2016/03/11 | 504 | 2,132 | <issue_start>username_0: What does this file do? It's part of wechat but is it just a cache of avatars? It's 256mb.<issue_comment>username_1: Clear out your old messages and see if the file shrinks (assuming you are concerned with this because of the large amount of storage it is taking). If it does, it's the file that contains all of your messages. Otherwise, it could be a cache or data that was never deleted by the app when it was done with it.
If you want to get rid of it to save space, do the things I listed below. If you are merely concerned with what it is, it's probably the file that contains your messages.
**If you are concerned with saving space:** After deleting your old messages, if the file does not shrink, clear the app cache through settings-> apps->wechat->clear cache and see if the file disappears. If it doesn't, that is a data file for the app probably holding contacts and messages. Deleting and reinstalling the app will likely delete the file, but double check that your contacts are saved somewhere else before doing that.
I must note, randomly deleting files that are not part of a cache can cause the app to crash when it is restarted or destroy data that you do not want to delete.

Instead, the folder tree contains several large cache files (for avatars and chats), and media files (pictures, music, video) sent to you by other users. This theory has been supported by the fact that, backing up the **tencent/MicroMsg** folders, uninstalling WeChat, reinstalling it, and then restoring the backed up tree, does not restore neither your previous chats, nor your old session.
Still, the app does never accomplish any maintenance on its cache, so that's a duty that must be carried out by the end user, while WeChat contacts and chats are stored within internal sql databases on the **/data** partition.

2016/03/12 | 835 | 2,720 | <issue_start>username_0: On my device, when I check the phone number through `Settings` > `About Phone` > `Status` > `SIM Status`, the phone number is incorrect. I ported my number over when I took out a new contract so I guess this is the number originally associated with the SIM. Is there any way to change this?
**EDIT:** Device is a Nexus 6P running M 6.0.1, no root.<issue_comment>username_1: I have found only two solutions:
1. Get Xposed and then either the app above or this one: <https://forum.xda-developers.com/galaxy-s3/themes-apps/app-sim-changer-change-registered-sim-t2106490>
2. Use an old Nokia/Alcatel phone to edit SIM phone number
Upvotes: 2 <issue_comment>username_2: A SIM contains multiple phonebook sections. One of them stores your SIM contacts. Another section contains "My Numbers" (MSISDN) with a max capacity of 3 numbers, usually.
Unfortunately, my phones are too new to access "My Numbers", and my phones that are old enough (2005) to edit them are out of reach.
Fortunately, I had a spare SIM800 *development board* lying around. [I hooked it up to my Arduino](https://www.factoryforward.com/sim800l-gsm-module-arduino-commands-library/) and started issuing AT commands.
Here's my conversation with my SIM card:
```
AT <-- Check if we are live and communicating with the SIM
OK
AT+CNUM? <-- Get own number
ERROR <-- CNUM failed, we don't have an "own" number
at+cpbs="ON" <-- Switch to "ON" phonebook: MSISDN (SIM own numbers)
OK
at+cpbs? <-- Get capacity of current phonebook
+CPBS: "ON",0,3 <-- Notice that there's no stored number (0 out of 3)
OK
at+cpbw=,"+639950001234" <-- Saving my number
OK
at+cpbs? <-- Get capacity of current phonebook
+CPBS: "ON",1,3 <-- Number saved (now consuming 1 out of 3 slots)
OK
at+cnum <-- Get own number
+CNUM: ,"+639950001234",145,,4 <-- CNUM OK
OK
AT
OK
```
Unplugged, then returned SIM to phone. After that, my phone now shows my number `+639950001234` instead of "Unknown".

However, I was recently trying to change the my number using that method, but found that I couldn't access the "ON" phone book. It turns out that you have to switch to local phone books before you can access it ( presumably only on some modems or SIM cards. ) You do this using `AT$QCPBMPREF=1` - after which the "ON" phone book is available. I found this info from the thread [here](https://forums.quectel.com/t/unable-to-access-own-numbers-phonebook/12832).

2016/03/12 | 390 | 1,274 | <issue_start>username_0: I'm looking for the whatsapp key file on my phone (which should be stored in `/data/data/com.whatsapp/files/key`).
Therefore I:
1. Rooted the phone Galaxy S5 (Android 4.4.2)
2. Checked the root status with Root Checker (it's rooted!)
3. Downloaded ES File Explorer
4. Opened /data/ folder in order to find the key file with ES File Explorer...
but the folder is empty!
Is that folder really empty or am I missing something?<issue_comment>username_1: ES File Explorer does not show `/data` on any of my rooted devices.
Not on my S5, not on my Note 2, or HTC One M7. I've heard other people easily using ES with root, but it never asks me for root permissions, just shows blank folders, like you.
I use [jrummy's Root Browser](https://play.google.com/store/apps/details?id=com.jrummy.root.browserfree&hl=en) on my S5, but any "root file explorer" will do.
ES File Explorer just doesn't cut it.
Hope this solves the problem.

Menu → Tools → turn Root Explorer to "ON".

2016/03/14 | 1,166 | 4,831 | <issue_start>username_0: Hello Android Enthusiasts!
I am the manager of an Internet Cafe on a cruise ship, and we're being plagued by a persistent problem that I can't quite solve.
We have a wireless network throughout the ship which can be used to access the Internet, but also includes a local intranet through which guests can view the daily events schedule, check their account, and use a free internal messaging service.
The issue we are running into seems to be with Captive Portal detection, and from my observations it appears to be affecting only Samsung phones (might just be S4 and higher), and has been observed on every OS from 4.2.2 and up. What happens is that they connect to the wireless network, and are then told that sign-in is required. A captive portal window will pop up, which does bring up our home page. If they then connect to the Internet, no problem. But if they just want to use the intranet, or if it takes them too long to fill out the user registration form, they get told that the network has been disconnected and we have to start over again from "sign-in is required."
I've done quite a bit of searching online for answers, and one is that the user must select "use network as is" from the captive portal options, but I see this option on very few devices. Other options have involved rooting the phone and running some terminal commands, which is obviously not something I can ask the guests to do.
We posed the issue to our shoreside networking team, and they came back saying they had whitelisted the following URLs and that this should fix the problem:
clients3.google.com/
apple.com/library/test/
captive.apple.com
connectivitycheck.android.com
connectivitycheck.gstatic.com
connectivitycheck.android.com/generate\_204
clients3.google.com/generate\_204
android.clients.google.com
It did not, phones are still being disconnected after about a minute if no Internet connection is made.
Is there anything else we can try? We are ultimately looking for a fix that won't require our users to do anything special.<issue_comment>username_1: We had a similar problem but I think it is not exactly the same problem.
We had an Galaxy S5 mini with Android 5.5.1 installed. We also have a "filter for websites" to deny access to some websites.
The problem here was that after starting the phone it connected and then disconnected immediately from network.
We found out that the network connectivity check is the problem. First tests show:
* When there is unrestricted Internet access it works.
* When there is no Internet access, network connection stays up. "No Internet connection" means we blocked all traffic on the firewall and all requests result in a timeout error.
When analysing more deeply and looking at the android source code we could identify the HTTP return code as problem. The device starts an HTTP request to connectivitycheck.android.com. This resulted in an HTTP 302 (moved temporarily) from our webfilter. Knowing this we did further tests:
* webfilter redirects access to connectivitycheck.android.com via HTTP/302 and all other internet sites are directly allowed: Here network connection was shut down again.
* deny access to connectivitycheck.android.com using firewall (therefore timeout for connectivity check) and all other internet sites are directly allowed: Here network connection stays up.
Therefore at the end we had two ways to fix the situation:
* allowing access to connectivitycheck.android.com without webfilter (therefore no HTTP 302)
* deny access to connectivitycheck.android.com on the firewall
But what about other Android versions? I did the same tests using a Galaxy S7 with Android 6.0.1. Here we never saw any problem. In Android 6 the connectivity check was slightly changed and is not suffering the above problem.
Upvotes: 1 <issue_comment>username_2: I've been plagued by this problem as well on one of [my open source captive portal libraries](https://github.com/tripflex/wifi-captive-portal/issues/7).
It seems to be due to the fact that Samsung has decided to implement their own code that will not trigger the captive portal login as it should when a 302 redirect is sent (and wifi does not have internet).
It seems as though you need to serve the captive portal file with 200 when they try to access `generate_204` endpoint, instead of just sending 302 redirect -- which works on every other device -- besides Samsung.
[Samsung Captive Portal Detection](https://community.arubanetworks.com/t5/Wireless-Access/Samsung-Captive-Portal-Detection/m-p/405934#M78972)
Thanks Samsung -- why can't you just follow normal captive portal standards!?
With this said though, i have had mixed results on different Samsung Sx devices... some don't even seem to query the `/generate_204` when connecting to wifi

2016/03/14 | 390 | 1,621 | <issue_start>username_0: I'm trying to remove permissions\* from certain bank app to prevent abuse.
I've managed to download apk file using emulator (AVD) and appextractor. I've used toolapk to extract the apk file and modified AndroidManifest.xml, repacked it and signed the file using jarsigner.
The installation on my phone fails with "App not installed.". The situation is the same on fresh emulator instance (no gapps). I tried to install unmodified version of the app on emulator with the same error.
How to get a more descriptive error message?
What am I missing?
My device is Galaxy Nexus running Cyanogen mod without gapps.
\*contacts & call log reading, sdcard r/w, etc...<issue_comment>username_1: If you use CyanogenMod, you don't need to remove Permissions from the APK. You can just go to Settings->Privacy->Manage App permissions after you installed the app and remove or add anything you want. Alternatively, which has even more control over the permissions (it can even be specific for which methods can be used) you can install the Xposed module XPrivacy (I have it installed and I use it a lot).

2016/03/14 | 467 | 1,876 | <issue_start>username_0: My Google Now for some time ago stopped speaking and executing commands.
When I do a command like 'set timer for ten minutes from now' it only searches Google for the text. Same for 'play <NAME> on YouTube'.
This began to happen when I logged in to Google Now and accepted the new terms.
When I say 'what's the Weather' it shows, but don't speaks out loud. I think that the fact of this working has to be with the google search itself and not the Google Now app.
Language is correctly set for english, and "Speech output" is set to on.
I have seem many other people with this issue googling for this, but yet no real fix.
Android is version `4.2.2` and Google Now is version `5.9.33.16.arm`.
**EDIT**: I have used Tasker + AutoVoice but don't believe this is the problem, because it begin right after I login to Google Now and accept the license; AutoVoice commands in Google Now are not working as well.<issue_comment>username_1: If you use CyanogenMod, you don't need to remove Permissions from the APK.

2016/03/14 | 933 | 3,934 | <issue_start>username_0: I have a Galaxy S5 with a fingerprint reader. I'd like to be able to unlock my phone with a PIN or pattern unlock, but I also want to protect myself from shoulder-surfing.
Is there a way to require **both** a fingerprint **and** a PIN/pattern to unlock the phone? If the fingerprint fails to read correctly, then a much stronger password would be required to unlock.
This would let me scan my fingerprint and put in my PIN/pattern without worrying that someone might see my PIN and unlock my phone later. It also protects me more from governments that can require me to unlock my phone with my fingerprint, since a PIN would also be needed.
Is there an lockscreen app, XPosed module, or other method that can enable this two-factor-like authentication?
I have a rooted Galaxy S5 running Android 5.0.<issue_comment>username_1: I use NOTE4 N910C. After upgrade to 6.0.1 such feature is avaliable by default. As I can see on <http://www.sammobile.com>, MM 6.0.1 is available for S5 so simply update Your phone via Odin
Upvotes: -1 <issue_comment>username_2: One solution is to use [Tasker](http://tasker.dinglisch.net/). Set up your phone to use a fingerprint as the standard unlock mechanism, with a strong password as the backup unlock (required if the fingerprint fails, or every time the phone reboots).
Next, create a Task named Screen Unlocked (or similar). In the Task, make it run the `Display`->`Lock` action. Set the Code to whatever pin you want. Check the `Remember Till Off` and `Full Screen` options, and make sure `Allow Cancel` is unchecked.
Next, create a Profile in Tasker for the Event of `Display Off`. When that profile is triggered, have it run the new Task you created. Add a second trigger to the same Profile to prevent this lock from happening if a call is in progress (using Invert). Otherwise, putting the phone to your head will turn off the display and cause the PIN lock (even though android knows it isn't actually locked and doesn't require tour fingerprint),and removing it from your head will show the PIN and block the call end and other buttons.
Finally, add a second Profile for the event Display Unlocked, and have it run the same Task. That way, if you do manually lock the phone while in a call with the power button (tripping the standard android fingerprint lock), it will properly show the PIN request on the screen again, without interfering with the end call buttons. Don't worry, having the lock show for display off and display unlocked will not, in fact, require you to type the pin twice.
With this setup, you unlock your phone with a fingerprint. When that is accepted, Tasker will prompt you for a PIN as well.
The reason you run this task on Screen Off instead of Screen Unlocked is that the Screen Unlocked creates a delay between unlocking the phone and showing the PIN request. By running the task on Screen Off, the PIN request is shown the instant you unlock with your fingerprint.
Note that this setup requires the PIN even if you use your backup password (if your fingerprint can't be read). However, I'm willing to live with that, since I rarely need to enter the master password anyway, and typing in a PIN afterwords is fine.
Protect Tasker
--------------
Since the PIN is stored in plaintext in Tasker, you should probably setup a PIN to open Tasker. Tasker has this built-in to its preferences, so you can require a PIN to view and modify any Tasker profiles and settings. Otherwise, if you leave your phone unlocked, anyone could find your PIN by viewing the Tasker config. In any case, don't use the same PIN for your screen unlock as you do for any other service like ATM cards or voicemail.

2016/03/14 | 3,709 | 11,967 | <issue_start>username_0: I started this question in order to have more light shed on a tool that's used by almost all the Samsung device owners that perform operations such as flashing: **ODIN**.
Since there's already a good answer that covers the meaning behind the most commonly used checkboxes, I would like to make everyone think about the ODIN configuration file, namely **Odin3.ini**. This file resides in the same position as the ODIN main executable, and it's mandatory in order to run the program itself. Its content (v.3.10.7) can be observed below:

As of recently, I performed some tests on the abovementioned values. You can see my findings in the answer below, which is freely editable by anyone.
Now comes the question part: was anyone able to ascertain the usage of those settings I was unable to/didn't test? For instance:
* Usefulness of `FactoryResetTime` - it doesn't reset the flash counter, before you say that;
* FTP connection output after editing `SLP`;
* Eventual output of **DeviceInfo**;
* Usage of `AuthorityKey`;
* Usage of `RtnForSprint` (only v3.10.7);
* Usage of the **T Flash** checkbox;
* What's supposed to be chosen as **UMS/PATCH** file - I've never seen one.
And yes, I'm aware that this is a bit of work, it's broad, and that it's not strictly related to Android. However, I found nothing on the XDA community, and I feel that we've yet to discover the real power of this ODIN tool. Any answer about this topic has the potential to help Samsung users out there to better understand this piece of software.<issue_comment>username_1: As suggested by @MatthewRead, this answer will reflect the same fashion of the question - it will be editable by anyone who has something useful to say.
In regards to the original question, here are my latest findings:
* **For label `[Options]`:**
+ `Title`: string. Used for changing the string displayed near "Odin"; freely customizable;
+ `FactoryResetTime`: unknown. I was able to change this value, but nothing happened;
+ `OptionEnable`: flag. When set to `0`, it makes any setting greyed out;
+ `PhoneEnable`: flag. Usually not present in a fresh Odin3.ini, can be manually added. When set to `1`, it makes **Phone EFS Clear** and **Phone Bootloader Update** selectable;
+ `DeviceInfo`: flag. Usually not present in a fresh Odin3.ini, can be manually added. When set to `1`, it makes the **DeviceInfo** checkbox available. Ticking the checkbox doesn't produce any result;
+ `SLP`: flag. When set to `1`, makes the program try a connection to **172.16.58.3** via FTP, in order to search for updates of the main executable. NOTE: I backtracked the IP, and it indeedly is a Korean server;
+ `AuthorityKey`: unknown. This seems like a string of some kind, and I think it's connected to the previous parameter, but I've no clues;
+ `RtnForSprint`: flag. Untested.
* **For label `[APOption]`:**
+ From `RePartition` to `NandErase`: flags. Editing them modifies the default behaviour of the corresponding option (`0` = unticked / `1` = ticked).
* **For label `[CPOption]`:**
+ `PhoneEFSClear`: flag. Usually, the corresponding checkbox is greyed out. By changing the value to `1`, it's possible to make it be checked, but still greyed out. Doing so will make the application prompt you to choose a firmware file, preventing you to start the flashing process only for, say, rebooting;
+ `PhoneBootUpdate`: apparently flag. The default value of `0k` may seem odd, but this flag does the same thing as the previous one, on the **Phone Bootloader Update** checkbox.
* **For label `[UIOption]`:**
+ `LED`: unknown. It may be anything: I changed this value, but nothing happened.
* **For label `[ButtonOption]`:**
+ From `Bootloader` to `UMS/PATCH`: flags. Editing them enables or "greyes" out the corresponding checkbox (`0` = disabled / `1` = enabled);
+ `USERDATA`: unknown, possibly flag. Since I didn't find any reference for this value in the program's code, I guess that this is a feature that will be developed in the future. For now, it does nothing.
* **For label `[D300Jig]`:**
+ `D300COM`: integer. I changed this value, but nothing happened;
+ `MicroCable`: flag. I changed this value, but nothing happened.
* **For label `[PortArrange]`:**
+ From `DPort0` to `SPort7`: unknown. Untested.
**Notes:**
* **`SLP`:** as previously mentioned, this flag triggers a FTP connection to a hard-coded IP address. I think that it may be useful in order to update Odin from a trusted source, but I've no proof. ***It would be useful if someone with an outdated Odin tests this***;
* **`D300Jig`:** I found a reference to this section in Odin's code, along with a string that's supposed to be displayed at output. Still, I wasn't able to make it work. Two Russian forums claim it to be a way to flash firmwares on old devices wo/ neither Loke nor the Recovery partition. More research is needed.
Upvotes: 2 <issue_comment>username_2: My guess is that The D300JIG is meant to be used with Samsungs proprietary JTAG unit called the Samsung Anyway Jig. Its what their software engineers and service centers use to revive bricked phones and flash firmware.
Either that or it could be related to flashing and servicing their D300 series smart TV's
Also Authority Key=pw is probably for a password needed to access Samsung secure servers on the ip address you mentioned above

**Odin3 keyboard shortcuts**
```

+ P AP
+ M CP
+ C CSC
+ S Start
+ R Reset
+ E Exit
```
**How Odin3 detects if some device is connected?**
Check the *names* of the entries in
HKLM\HARDWARE\DEVICEMAP\SERIALCOMM
contains '*mdm*'
and if it's *value* starts with 'COM'
Sample
```
"\Device\ssudmdm0000" "COM8"
```
Note: "Odin\_Multi\_Downloader\_v4.44"(2011) is more picky and only finds
"\Device\sscdmdm0..9"
"Odin3.09"(2013) finds
"\Device\ssudmdm"
"\Device\sscdmdm"
"\Device\ssacmdm"
"\Device\ssadmdm"
It's 'SAMSUNG Mobile USB Modem'(USB\VID\_04E8&PID\_685D&Modem)
that writes the entries to 'HKLM\HARDWARE\DEVICEMAP\SERIALCOMM'
-> Enabling/Disabling this in the Windows device manager triggers the
to log entries "Removed!! / Added!!" in Odin3
But instead of the modem disable/enable 'SAMSUNG Mobile USB CDC Composite Device' for proper reinitialisation. Or get [Nirsoft DevManView](http://www.nirsoft.net/utils/device_manager_view.html) and do it by this cmd-script:
```
::Comment in incase Odin3 'hangs' on "SetupConnection.."
:: ... and so keeps an open handle to "\\Device\ssudmdm0000"
:: ... that prevents/lock the device and dependencies from being removed
::taskkill /fi "IMAGENAME eq odin*"
DevManView /ShowLegacyDrivers /use_wildcard /disable "SAMSUNG Mobile USB *"
DevManView /ShowLegacyDrivers /use_wildcard /enable "SAMSUNG Mobile USB *"
```
then just create a link to the desktop and set in the link properties a hot key combo
like ALT+CTRL+Y to run it.
Well alternatively so can also do it the plug'n'play way, pull the USB plug and them plug it in again.

I have everything turned up to maximum but still very quiet like it is on low.
Has anyone experienced or heard anything like this or know of some ways on how to fix this and make the volume louder?
I am also running a Droid Turbo 2.<issue_comment>username_1: Fixed it.
You do need to go in and delete the cache after an update. Everything sounds correct now.
**Get into bootloader**
1. Power off phone
2. Press and hold Vol down , press power button until you seebootloader
(3 happy androids on skateboards at bottom of page). Release vol
down.
**Open Recovery**
3. Select Recovery by using vol down, press Power to select.
4. Wait. This takes a while.
5. You will now see a screen with a picture of a phone with a red
exclamation mark on it. Press in power button, keep it pressed, and
press volume up button shortly (do not keep it pressed). Release
power button.
6. You will now see a menu with yellow text on-top of it.
7. Select Wipe Cache partition with vol down. Press Power to select.
Now it wipes the cache partition. Done!
8. It should now have marked Reboot system now. Press Power to select.
Phone will now reboot to normal mode.

2016/03/16 | 526 | 1,847 | <issue_start>username_0: I have a Samsung Galaxy S6. This year, I'm doing an experiment wherein I do not participate in Daylight Saving Time (DST). However, my phone automatically adjusts itself for DST.
How do I disable this? Is there any way to stop my phone's clock from adding or removing an hour twice a year?<issue_comment>username_1: Android uses [`tzdata`](https://en.wikipedia.org/wiki/Tz_database) (IANA Time Zone Database) to store time zone rules, which the Daylight Saving Time (DST) information is also included. The rules tell when DST is observed in a given time zone. Thus, it is not possible to disable the DST if using a time zone that observes DST.
Therefore, to "disable" the DST, choose a time zone that doesn't observe DST and has the same offset as the current time zone (refer to [Wikipedia's List of tz database time zones](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones)).
Example:
* Brussels, Belgium (GMT+01:00) [observes DST](https://www.timeanddate.com/time/change/belgium/brussels); while it's on DST, its offset will be GMT+02:00.
* Brazzaville, Congo (GMT+01:00) [doesn't observe DST](https://www.timeanddate.com/time/change/congo/brazzaville).
*Turning off the **Automatic time zone** option* may also be needed to prevent it from being changed back to the network-provided time zone.

When I access YouTube from Chrome it plays 360p videos; the quality of the same video was way better when played from the browser.<issue_comment>username_1: The YouTube quality settings are determined by each video (although if you select a higher quality, it will default to that for the next time). Hit the three-dot menu button:
[](https://i.stack.imgur.com/n4fvfm.png)
Then the Quality cog button:
[](https://i.stack.imgur.com/bSO7Cm.png)
Then you can select the quality setting.
[](https://i.stack.imgur.com/h7zmym.png)
Other videos might have more options for the quality setting:
[](https://i.stack.imgur.com/lo55Om.png)
This completely depends on external factors like, for example, the size of the source video that was uploaded to YouTube.
You can also (from the 3-dot menu on the app Home) go to Settings → General to turn off the "Limit mobile data usage" option, which will allow videos to default to higher quality when you are not on Wi-Fi.

ADB (user 2000) doesn't have adequate privilege to directly read the database *mmssms.db* located under *com.android.providers.telephony/databases* - the same database which keeps records of your received and sent SMS and MMS. Neither does it have the permission [android.permission.READ\_SMS](http://developer.android.com/reference/android/Manifest.permission.html#READ_SMS) to read SMS.

So, all you can do is use an app to do the job for you, such as what Aaron [suggested](https://android.stackexchange.com/a/139866/96277) or if your vendor provides a software to manage your phone from PC, then consider trying it. It may be having the option to backup SMS and MMS.

But, how do I give Tasker the permission to write to external SD Card?

where Pent said:
Here's a nice link explaining the situation:
<https://groups.google.com/forum/#!topic/eyes-free/rspqjlmu_ss>
As I understand it, if on lollipop or 'portable' mode on marshmallow are used, access is required via a special API. I've looked at this API (DocumentFile) and it's going to require rewriting huge chunks of code used for the file functions, plus some awkwardness with the user pre-accepting file operations
on external SD (and I don't know how long that preacceptance stays valid, potentially making it
useless for later automation)
Summary, I'm not going to be doing this in the near future, if more mainstream devices start to get SD I may reconsider.
Upvotes: 2 [selected_answer]<issue_comment>username_2: First link above have the solution on Dustin answer. You should use any file manager to create a folder inside `data` like that
`/storage/sdcard1/Android/data/net.dinglisch.android.taskerm/`
And use Tasker to copy to that folder. You can move it elsewhere later.
A folder like
`/storage/sdcard1/Android/data/net.dinglisch.android.taskerm/whatever`
will also work. Tested on Android 5.1.1 RedMi Pro no root device.

2016/03/17 | 1,428 | 5,341 | <issue_start>username_0: I have a nexus device. Whenever new version of android is released, the phone gets it almost instantly. I want to know why other manufacturers doesn't update their software in the same timespan. For some manufacturers, this process can take several months.
**Is there a technical challenge that prevents them to do this?** or is just matter of not allocating enough resources to do this?
I know about the differences between different ROMs and manufacturers, UI layers and so on... I'm asking is if so difficult (and why), or if manufacturers just don't want to do it, to release the new ROMs earlier.
To give an example about what I'm saying: when I updated from Windows 7/8 to Windows 10 in several computers (MSI, Acer, Lenovo, and custom build), I just clicked the "update" button and all the computers updated fine, without drivers problems... Why android is not the same case? Every major release introduces several **breaking** changes that makes it difficult for manufacturers?<issue_comment>username_1: The thing is, other manufacturers have to update their skin and extra features they introduce with the product. Not everything would be compatible so they test it till everything is fixed! Moreover, there is this whole career thing, which is super complicated. Therefore, other's have to wait. While on the nexus devices, they are on Pure Stock Android with no customization. Thus, Google controls the updates and they get updates quite quickly.
EDIT:
The complications of the career is explained beautifully in a howtogeek article, you may want to check it out:

Notice that the graphic has a blue 'Google Play Edition' path which was when non-Nexus manufacturer had devices with only stock Android. This blue line would be the closest approximation to a Nexus device and notice how it doesn't have as many blocking points as the orange 'Carrier Device'.
*Comparing to PC*
You have to realize that the PC Hardware layer is relatively standardized on a x64 architecture either from Intel or AMD.
Android has multiple CPU architectures to support (ARMv7,ARMv8,x86,x64,MIPS) manufactured by different vendors (Samsung, Qualcomm, NVidia, Rockchip, Intel, MIPS) and its in Step 5 that the various vendors have to see what will get support. Way more customization goes on here than a normal PC.

Fragmentation is the key
========================
[Update process graphic](https://android.stackexchange.com/a/65587/131553) pointed out by benjaminS, beautifully illustrates steps involved. Steps 4 and 5 are hardware related , which is **heavily fragmented** . This is a major challenge.
Let's start by taking the example of Samsung, which launched Note 2 devices, in two variants,which are identical in all respects, except the chip set (Exynos , homegrown Samsung processor and Snapdragon). This led to different ROMs being developed , tested and ported and released at different dates (don't remember the specifics, was about 4 months as I recall-talking of international versions). This is with only critical hardware difference. Next, consider various other hardware elements-screen, camera, earphones to name a few others and fragmentation mushrooms. Add to that low cost competition coming up with [rebranded](http://www.droidiser.com/2012/10/exclusive-truth-behind-indian.html?m=1) devices and the panorama of fragmentation grows huge. Hence,
* OEMs have to [customise](https://android.stackexchange.com/a/15719/131553) ROMs from source code. Adding bloatware and customised UI takes more time
* ROMs have to be [different](https://android.stackexchange.com/a/35928/131553) for different hardware, though they may be similar in other ways
* ROMs have to be [country /region specific](https://android.stackexchange.com/a/82599/131553) **even** if the hardware is same
* Carriers add their own value and time penalty
it should be pretty obvious now why rolling out is delayed and comparing this scenario with PCs didn't hold given the standardised architecture

2016/03/18 | 486 | 1,831 | <issue_start>username_0: Currently, TWRP backups don't include `/data/media`, and this doesn't appear to be on the developers' radar at all ([the issue for it over at GitHub](https://github.com/TeamWin/Team-Win-Recovery-Project/issues/276) is just a bunch of +1s with no official response). Now that we have SELinux to contend with, simply copying the files back and forth is apparently [no longer an option](https://github.com/TeamWin/Team-Win-Recovery-Project/issues/276#issuecomment-116733341), and there are a number of different ways to access `/data/media` throughout the filesystem, each with different effective owners and permissions.
In excruciating detail, how should I approach backing up and restoring `/data/media` so everything is restored exactly as it was and my apps don't have trouble with the resulting permissions?<issue_comment>username_1: I recommend directly copying files from/to `/sdcard`.
The `sdcard` service will handle all the permissions and SELinux contexts for you.
The `/storage/emulated/0`, `/mnt/shell/emulated/0` and `/storage/emulated/legacy` are all shadow reflexes of `/data/media` (typically `/data/media/0`). In the `/init.rc` file you can find out that the `/system/bin/sdcard` is a service that controls all of them, so you can just copy the files in `/storage/emulated/0` with ease. All other directories like `/sdcard` and `/storage/sdcard0` are symbolic links. They don't matter at all.

2016/03/18 | 806 | 3,123 | <issue_start>username_0: I updated my Z5 to Marshmallow 6.0 yesterday. Worst mistake of my life.
It locked out my phone and wiped some SD photos (so I couldn't get past the keylock screen - on entering the correct code, it goes black momentarily, thinks about it, then returns to the lock screen on a never ending loop). Clicking any notifications fro the dropdown menu brings up the keylock screen again, and on inputting the correct keycode in, I get the error message 'unfortunately, system UI has stopped working' then it returns to the locked screen again.
I can receive calls, emails and texts...but I cannot access them, or send anything.
Worth noting that I already did a factory reset (and lost further photos from my sons 5th birthday), which fixed the problem last night...and this morning it return in the same manner as above.
About to do a further factory reset, but that's no way to live my life with a 3 month old phone....
Someone please help (And also any help on recovering my SD images would be welcomed!)
I have been to x2 O2 stores, with one Guru who couldn't' find a solution.
THANKS!
Maria<issue_comment>username_1: You mentioned that your device is the Z5. I assume that your device is the one mentioned below:
[Sony Xperia Z5](http://www.gsmarena.com/sony_xperia_z5-7534.php)
I did a quick search, and found that they are supposed to be releasing an update that fixes the issue:
[Sony Forums and Tech Support](http://talk.sonymobile.com/t5/Xperia-Z5-Z5-Compact-Z5-Premium/System-UI-stops-after-6-0-update/m-p/1102398/highlight/true#S15231)
Now, in reference to the Photos. I am also assuming that the photos are saved on the phone's internal SD Card, and not a removable external card. If this is so, can you connect to the phone via USB/ADB? This could allow you to retrieve the photos, if it works. In order for ADB to work, you would need to have USB debugging enabled. In order for USB to work, you need the proper device drivers installed on your computer. When connecting the phone to the computer, you should be able to access the phone's internal SD Card (but not the system partition). That should allow you to copy the photos over.

There are a number of ways to get to Google's Device Manager. One ways is:
<http://play.google.com> -> Click on the `Gear icon` at the top right corner of the screen -> Click on `Android Device Manager` -> Login -> Select your target phone (if you have multiple devices) -> click on `Lock`. Follow the prompts to change/set your lock code.
So far this has worked to resolve the issue. I'm not sure if something specifically has to be done to enable this feature, but since you are experiencing problems, you might consider testing the steps when you're not experiencing the immediate problem so that you can verify that it will be available the next time next time you need it.

A few days ago, I received a whatsapp call (media audio) while the phone was connected via bluetooth to the car, and I successfully used the audio car system for the whatsapp call.
Since then, unfortunately, whenever I connect the phone via Bluetooth to the audio car system, only media audio (e.g. youtube videos, mp3, music, whatsapp calls, etc.) is transmitted, whereas calling another telephone I do not hear anything via car stereo.
The phone works because if I disconnect the Bluetooth, the call is active and I can use the phone to speak/hear.
I tried to remove the Bluetooth phone device and add it again, and to disable transmission of media audio via Bluetooth to the car system, but the problem does not disappear.
Any help?
Thanks!<issue_comment>username_1: I removed the phone/device again from the bluetooth car audio system and linked it again via bluetooth, after changing the phone bluetooth name.
It did not work.
I then turned off and on the phone.
Now it seems to be working, not sure how/why though!

2016/03/18 | 1,046 | 4,262 | <issue_start>username_0: I have an Android 6, Samsung S6 smartphone and today I bought a tram ticket via SMS. Before sending, a warning popped up asking if I wanted to grant the Messages app the permission "SMS Services that cost you money". I assume this was because the SMS ("Premium SMS") is overcharged (by the price of the ticket), since the app never asked for this permission before sending a SMS.
I replied Yes, since it was a legitimate purchase, but I was in a hurry and involuntarily I ticked the option "remember my choice".
Now I would like that Android keeps asking me before sending Premium SMSs, since it's a security risk, but I couldn't find a setting to disable this option. Is this possible? Or the only way is to hard reset my phone and reconfigure it from scratch? I can't believe Android doesn't offer this option.<issue_comment>username_1: Well, bad news: It appears to be another of these annoying, huge Android bugs for which there's no solution yet.
The only workaround is to use another app for sending SMS, or to hard reset the phone.
From the [discussion](https://productforums.google.com/forum/#!topic/nexus/WjO0Sz5N-ew;context-place=forum/Nexus) linked in the comments:
>
> (...) the particular drop-down setting - for premium sms - you could toggle through back in an app's permissions in previous Android versions starting from 4.2. The case would arise if when using an app that required to send an sms to a 5-digit number, the OS would present a 'You might get charged' warning popup, which would prompt you to Allow or Deny sending the sms. If you also checked the "Don't ask me again" option then this warning popup would not appear again next time.
>
>
> A user could reset that checked option in Settings> Apps (or Application Manager), going to the permissions section of the specified app and uncheck the premium sms "lock"; With Marshmallow though, there does not seem to be a similar option back in app settings.
>
>
> The permissions toggles only enable/disable the standard SMS sending and have no effect on a premium sms locked option when they are enabled, leading to a blocking scenario where if a user had selected the "Don't ask again" option initially, he/she will not be able to resend an sms from the particular app.
>
>
> Even worse is the fact that uninstalling and re-installing the app does not reset that initial selection, rendering the sending of sms to 5-digit numbers impossible and beyond the user's control.

In the discussion you can read the comments of other users which have the opposite problem -- they replied "No" and ticked "Don't ask again", and now they are forbidden from sending Premium SMSs.

2016/03/19 | 1,106 | 4,787 | <issue_start>username_0: So since I updated my phone, there seems to be a mysterious 3-4GB of "System Data" on my phone's hard drive that I can't get rid of.
Here are some screenshots of this:
[](https://i.stack.imgur.com/xmfpzl.png)
I have an LG Leon running Android version 5.1.1
Is this a known issue with updating Android or is this a new thing?<issue_comment>username_1: That is probably a bunch of stuff you should **not** remove. For example it could contain the Android OS file images that are mounted during start up for your different directories: /system, /data , /sys, etc. These are things that are vital to your phone running, and thus removing them is a bad idea.
Upvotes: -1 <issue_comment>username_2: After reading the question again and looking at screenshot this may be reffering to the System data stored on your /data partition. If you can tap that entry and see if it gives you any more details as to what it is reffering to. This probably contains the OTA update in full (along with other settings as well). So you could possibly drill down inside of the system data option to see what is all there. an Update Zip is going to be rather large (for android and mobile device files anyways) on the order of 300-400 MB + (depending what is all in it). You would be safe to delete the OTA files since they are no longer used after the update is installed, BUT AGAIN A WARNING... This System Data Items Entry is probably reffering to a lot more than just the OTA download itself I would not just delete that entry I would instead go in to it for detail, and if none is given there then use something like ES File Explorer (once open in app settings>view check the box for showing hidden files) and go looking in /sdcard/ for a directory containing most likely a zip or a couple zips (may be separate zips for the ROM, Recovery, Fastboot, Radio, etc. depending on your device and manufacturer and how they handle things).
Reminder: as long as your google account is syncing correctly all your app data (not all apps but the majority have this enabled) along with your contacts (and even pictures if you set that up) are all sync'd back to Google so even if you delete this whole directory and have issues and have to do a factory restore and wipe all data when the phone starts up and you login again it will re-download all that data for you. Just be sure to go in to system settings>Accounts and tap google and tap the entry for your account and make sure every box is checked (is OK if browser data has ! and you see a chrome entry there your OEM browser is failing to sync but Chrome is not and has everything) Also can uncheck items if you don't care whether the data is backed up or not (like Google Fit LoL). I will still leave the original answer below as others may find the info useful.
The system partition by default is not accessible to the user. NOW that is not to say it forgot to clean up behind itself if you did an OTA update. Without rooting your phone the only way to probably adjust this is to grab a factory zip from LG for your device and flash it using their instructions. This will remove everything in system and do a fresh install. You are right though it should not be anywhere near that size.
BUT BUT BUT
If you are not using a rooted device you will never be able to write anything to that /System mount point so as long as the phone works it really does not matter if that partition is maxed out it will never be written to anyway. If you don't notice other little issues, and are happy with the phone I would just use it as is. Even if you have root again you will not be placing anything in /system (if you do it will be one or 2 tiny things mostly).
/system does NOT affect /Data so no matter how much storage your /system uses it will never take away from nor add to the storage space in /data.
For instance even if you update a google app that is installed in /System Android actually installs the update to /Data and stops using the version in /System (while still leaving it there untouched in case you go to Settings>Apps> and tap Uninstall updates. If you do this it removes everything for the app in /data and begins to use the copy in /system until the next update).
Basically, Android writes things to System during SYSTEM install (and that only really happens through the recovery menu not the actual Android OS itself (the recovery menu can actually be thought of as a second tiny OS that lives inside your device alongside the full larger Android OS kinda) and after that everything gets stored on /data and nothing gets written to /System only read from (it's a security thing if the system can write to /system so could say a virus which would be a bad thing).

2016/03/19 | 613 | 2,038 | <issue_start>username_0: I have a Samsung Galaxy S4 Mini (GT-I9195) and successfully installed CyanogenMod 13 with the CM 13 Recovery on it. Now I am stuck with the installation of [GApps](http://opengapps.org/?api=6.0&variant=nano) by means of TWRP.
I have tried to follow [this](https://twrp.me/devices/samsunggalaxys4miniuscellular.html) tutorial to install TWRP (3.0.1 or 2.8.7):
1. App Install Method: it tells me that something went wrong and it does not boot the recovery, indeed. What seems wired to me is that when I have to choose an image it shows me the device code **serranolteusc** and **serranoveltexx** for my S4 Mini rather than **serranoltexx**, like on the website of CM 13. Is this normal?
(I even tried Flashify instead of the TWRP manager, but it did not function!)
2. Since I am on Linux and have no Windows, I cannot use the Odin method. But I tried Heimdall via `heimdall flash --RECOVERY twrp.img --no-reboot` to no avail.
3. I tried the dd Install Method via `dd if=/sdcard/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery`, but it still does not boot into recovery mode. Is it possible that there is an issue with the path in `of=/dev/block/platform/msm_sdcc.1/by-name/recovery`?
Is it possible that there is no TWRP for **serranoltexx** available?<issue_comment>username_1: If you are ever in doubt about partition paths (and said device is supported by CyanogenMod or Lineage OS), you can check this from their sources. But to your question at hand, looking at TWRP device trees, you need to use "serranolteusc" as "serranoveltexx" is meant for the newer 64-bit variant (why name them the same is beyond me). Using the image for "serranolteusc" with the Heimdall or terminal and `dd` command should be enough to get TWRP installed.
If that doesn't work, maybe provide a logcat of when you try to `dd` and see if it complains about anything specific.

2016/03/19 | 923 | 3,748 | <issue_start>username_0: I have just bought a Samsung Galaxy S7 (running Android 6.0.1) and installed the Outlook app. Email syncs fine but I see nothing on my calendar. When I tap the top left burger (?) menu "Kevin's calendar" is almost always unchecked. I check it but still nothing shows.
I have also tried resetting my account by going to the calendar settings (cog in the top right, opening my @hotmail.co.uk account and pressing RESET ACCOUNT).
I've also tried uninstalling and reinstalling the app.
It worked fine on my Android S4.<issue_comment>username_1: In the hope that this will help someone else.
1. Uninstall the Outlook app
2. Go to "Settings" > "Accounts" and remove all accounts relating to hotmail.co.uk
3. Add a new "Microsoft Exchange ActiveSync" account and enter your details.
Once successful you can view your email by using the pre-installed "Mail" app and you can view your calendar entries by using the pre-installed "S-Planner" app.
If you want to use the Outlook app then follow these further steps
4. Reinstall the Outlook app
5. Open the Outlook app and follow the instructions in the setup wizard. Choose "Exchange" account when given a choice between "Office 365", "Outlook.com" and "Exchange".
6. You'll have to enter your username and password several times and accept all permission prompts.
You should now be able to see your calendar entries in the Outlook app.
(strictly speaking I don't think you need to do step 3 if you carry on doing steps 4 - 6, but I'm not prepared to go through all that again to prove it)

2016/03/20 | 690 | 2,617 | <issue_start>username_0: Is there such a thing as a searchable database or a website anywhere online where someone can type in the name of an app or a package name and see a summary of what the app is for, if it is a system app, if it is just Android or iOS, list of permissions needed, etc?
I guess sort of an app dictionary/encyclopedia with more in depth info than what searching Google Play will give me.<issue_comment>username_1: I am not very sure if any such searchable database or a website is even possible for anyone to create (including Google itself), given the current size of Android apps, the indie app development ecosystem of Android and plethora of Android devices on offer, which varies from country to country and more.
I guess the simplest approach is to take it case-by-case for each app.
**If you find a new/unknown app, just do a quick Google Search using app's Name.**
Most likely that you will find a link to Either Google Play store (if that app is hosted on Google Play) or some other Link from where you can download the APK for the app. Developers tend to provide enough information (such as app permissions) about the app so that user can see and install apps through these links.
Having said that, I found few useful links/sites which can be visited for app info.
[Link-1](http://www.freewarelovers.com/android/apps), [Link-2](http://www.appsapk.com/android/all-apps/)
Of course, these links/sites have their limitations and they do not have EVERY Single app which is ever developed for Android.
Upvotes: 0 <issue_comment>username_2: Unlikely such a site exists *and is complete*. See the two links in [this answer](https://android.stackexchange.com/a/140119/16575): [The first](http://www.freewarelovers.com/android/apps) currently covers 1718 apps, [the second](http://www.appsapk.com/android/all-apps/) ~7,350 apps. [My own site](https://android.izzysoft.de/) currently covers ~13,000+ apps (from multiple sources: GPlay, F-Droid, Aptoide "Apps", Xposed Repo).
Google Play covers >1 Mio apps, and I have a lot of apps not covered there (so do F-Droid (~1,800 apps) and Aptoide (~90,000 apps in their main repo, plus tons more in other "user-repos"). Then there are those apps offered outside of stores at all, e.g. only on the website of some company.
All that's left is typing the package name (surrounded by quotes) into a search box (Google, DuckDuckGo, whatever) and see what pops up. As you're specifically after malware: those results sometimes include links to scan details by several known anti-X companies, which are interesting (but not easy to read).

2016/03/20 | 748 | 3,020 | <issue_start>username_0: I'm an Android developer and I have a non-technical question regarding major Android version upgrades (e.g. from Android 4.x to 5 or from 5.x to 6).
Do any of the big Android device vendors offer these kinds of upgrades without wiping the data on the device?
I'm asking this question because I need to know if this kind of scenario should be supported by the app.<issue_comment>username_1: I must admit that I'm a bit confused by this post. Granted, I haven't been an Androider from the word go (my first device was a Nexus 7 running Jellybean), but every major update I have done has not required a factory reset (unless of course it has got stuck). This is true for all three of my devices: my Nexus 5, my Nexus 7 and my Nexus 9.
The biggest update I have done was on my Nexus 5 and Nexus 7, going from KitKat to Lollipop and that kept all my data. And of any update, KitKat to Lollipop would be the most likely to require a reset - they're very different.
Mind you, they are pure Android devices. So I'd say that if you have an official Google device (be it LG, HTC, etc.) with vanilla Android, you're pretty safe.
(Also, it would not be in the best interests of the vendor to require a factory reset before an update because then there would be less of an incentive to update.)
Upvotes: 4 [selected_answer]<issue_comment>username_2: We have had several devices from Samsung, ASUS, Sony, Motorola, Huawei etc. get major upgrades from Android I to J, J to K, K to L and now from L to M but we never had any of the data affected. Of course, all of these were non-rooted devices with manufacturer or Google provided OSes and the updates where issued/pushed by the manufacturer. This would make sense, as there may be important data stored by individual apps.
The case may be different for custom ROMs, though good custom ROMs would try to retain app data during upgrades. Having said that, it is always wise to backup your important data before performing any OS upgrades, minor or major.
Upvotes: 2 <issue_comment>username_3: As a general rule, mobile OS updates do not wipe user data when transitioning from 1 version to the next. Such wipes would be devastating for the large amount of users that have very little tech knowledge and don't take basic precautions like backups and storing their files in multiple locations.
However, quite a few apps run into issues when upgrading the OS version. Even system apps can have this issue. For example, when I upgraded my S4 from 4.4.2 to 5.0.1, the "recommended apps" app that recommends apps to use when connecting a headphone kept crashing when doing so. That was solved after a factory reset. That's why it is recommended to do a factory reset after a OS update. A not insignificant part of the userbase does factory resets in this manner.
As an app developer, you should least prepare for the user doing a factory reset at any time. With Marshmallow, that should be easier considering google now backs up certain app data.

2016/03/20 | 1,013 | 3,662 | <issue_start>username_0: I have been facing a severe battery drain issue on my official Cyanogenmod custom ROM. After discussing it on community forums, it was suggested that I use logcat for troubleshooting the problem.
**Problem:**
Every time I disconnect my device after a complete charge, it drains battery rapidly. It loses almost 50% in 15-20 mins. As mentioned above, I am planning to use logcat to try and capture the issue. I am planning to run `adb logcat` immediately after unplugging the phone from power. However, I have used logcat in the past and found it very very difficult to extract specific data from the large output. I already went through [the official logcat help page](http://developer.android.com/tools/help/logcat.html "Logcat Page") and [Reading and Writing Logs](http://developer.android.com/tools/debugging/debugging-log.html#alternativeBuffers) to see if I could find something useful, but I could not find a solution for my problem.
**Question:**
* Is there anyway to use filters or some other feature where I can limit the logcat output to the stats which are only related to battery usage?
* Can something like `adb shell dumpsys batterystats > batterystats.txt` be of better use to me? If so, how do I use it to get what I want?

Sure. The easier way is to used the device monitor from Android Studio. The more complex way is to use the command line interface to adb logcat (it uses the ANDROID\_LOG\_TAGS env var). Cf [logcat Command-line Tool](https://developer.android.com/studio/command-line/logcat.html) documentation on developer.android.com.

Battery drain is mainly because of some unexpected conditions occuring (errors conducting applications to loop infinitly, badly detected devices making access sub optimals, for ex reading byte per byte instead of Mb per Mb, etc). You should use the filtering ability of adb logcat to find such unexpected conditions. But be warned that such tools are mainly used by app or even platform devs, and it can be sometimes a little but complex to interpret such logs. However 100% of the guys who succeeded, have tried ;-)
Upvotes: 0 <issue_comment>username_2: Are you sure, it's not any app that is draining your battery? You can find this out by booting you phone into Safe mode. Read [How to boot your phone into safe mode](https://android.stackexchange.com/questions/39228/how-can-i-reset-my-developer-options-or-otherwise-boot-my-galaxy-s2-on-cm10-1-a) for instructions. If your battery doesn't drain in Safe mode, try uninstalling the apps that you installed after you started seeing this weird behavior. If you are not able to figure out which app it is, try factory resetting it. Also, if the battery is draining so quickly it might very well be a faulty battery.

2016/03/21 | 801 | 3,116 | <issue_start>username_0: I am coming from iOS to my first Android (Samsung Galaxy S7) and having hard time adjusting. The first thing that is throwing me off is lack of a calendar app.
The phone came with Samsung's own S-Planner, but I wanted to use a more native android app (so that if my next phone is not Samsung, I don't have to relearn). However I cannot find anything else installed on the device. Any online search results in various 3rd party calendar apps. So, is there no such thing as a "***native* android calendar app**"?
Secondly, the 3rd party calendar apps have options of syncing to Gmail/Exchange/other accounts, but is there no such thing as "**on-device calendar**" (like on iOS)? One that isn't linked to some account online?
Thank you<issue_comment>username_1: Google Calendar could be considered as native android calendar app. You can [download it from Google Play](https://play.google.com/store/apps/details?id=com.google.android.calendar). But I personally don't like it.
As for device-only calendar - I have never seen an android phone without such a calendar (I'm not familiar with Samsung devices though). Normally you can choose a calendar during creating an event.
Upvotes: 3 <issue_comment>username_2: The native AOSP calendar app was replaced by Google's own**1**. It went by the package name `com.android.calendar`, but is no longer found in either *Google Play Store* or on *F-Droid* (you can find its code [on Github](https://github.com/android/platform_packages_apps_calendar), though). As for synchronization, that's usually not done by the calendar app itself but by the corresponding sync service; most calendar apps use the "calendar provider" of the Android system to store their data.
If you want a "local calendar" that's not synchronized at any cost, and your device doesn't offer such, you can e.g. use [Offline Calendar](https://play.google.com/store/apps/details?id=com.droidwave.offlinecalendar); but that app doesn't seem to be maintained anymore (last version is from 2013).

I had tried it earlier, but gave up since I found interface not very friendly (for me at least-your experience may be different). Exporting to new device could be as you would do for other apps (backing up and reinstalling) or as I see in developer reply suggesting interface with another app to export(see 15/09/2015)

2016/03/21 | 726 | 2,889 | <issue_start>username_0: Google Maps are arguably the most accurate online maps in the world, but the problem is that the app itself has many limitations when it comes to offline use like not allowing downloads of maps bigger than a certain size and deletion of stored maps after a number of days.
Is there a way within Google Maps or using 3rd party software (available on F-Droid maybe) that can download Google Maps and store them indefinitely and also allow offline search? Or is there an alternative way to do this?<issue_comment>username_1: I use [MAPS.ME](https://play.google.com/store/apps/details?id=com.mapswithme.maps.pro) as an alternative. It works perfectly offline, you can save places, search anything in the downloaded maps, and it has a router for driving and walking too. Its map data is from [OSM](http://www.openstreetmap.org). It is also accurate enough, (but) it can be edited by anyone, though this *can* lead to mistakes (I've not encountered any of them so far), and on the other hand, sometimes it is even more detailed than Google Maps.
Anyway there are a lot of apps on Google Play using OSM's data.

Pros
* Uses less memory
* will automatically download offline maps along your route in case you lose signal
Cons
- offline maps self delete if unused for a time
---
Here WeGo is a good Android application for offline maps.
Pros
* You can download offline maps for your state/region, country, continent, or entire world.
* if you phone has aGPS, this application will work with or without cell service as long as you have downloaded the maps for your location and you can see the sky.
* Maps stay on your phone until you delete them.
* Gives you directions via walking, biking, public transport, lyft, driving, or ride share.
Cons
* You can not add nicknames to saved locations
* Uses more of phone memory (Map of the entire USA is just over 8GB)
* Managing saved places can be tedious.
---
For my personal use I usually use Waze for my day to day navigation needs, however when I go on long trips I use Here maps to download maps for regions I expect to be in, in case I lose cell signal or data connection. I only use google maps when Waze is having trouble with my request.

2016/03/21 | 821 | 3,219 | <issue_start>username_0: My Moto G phone (3rd gen; Android 6.0) used to charge rapidly and last over a day. I upgraded it from Lollipop to Marshmallow in mid-February and it still performed well. However, for the past 3 weeks or so, its battery life has suddenly pretty much halved. It also gets warm to the touch even when left alone!
I'm familiar with general tips for increasing battery life, such as those [provided by Motorola](https://motorola-global-portal.custhelp.com/app/answers/prod_answer_detail/a_id/105541/p/30,6720,9390) or on [this site](https://android.stackexchange.com/q/476/155892). From looking in GSAM Battery Monitor and Settings → Battery the most likely culprits seem to be Google Play Services and/or Google Calendar. But battery drain is still high even after denying all but the Calendar permission to Google Calendar; and it's not obvious how to configure Google Play Services.
If anyone knows of a solution that doesn't involve rooting the device I'd be very grateful. Or do I just have to wait for Google to release a bug fix?<issue_comment>username_1: Are you rooted or okay with rooting? Do you have Xposed Installer installed or okay with installing Xposed Installer?
If so, you can get Amplify from <http://amplifyandroid.com/>. The app basically lists all of the wakelocks and alarms (not alarms that humans use) that cause wakelocks and tells you how many times it woke the system and for how long. From there you can start delaying the alarms/wakelocks to increase battery life. Amplify **dramatically** increased my idle battery life.

Before I did the reset the battery drain looked like this in Settings > Battery:
[](https://i.stack.imgur.com/fjGsj.png)
The shallow gradient was when I booted the phone in safe mode. This at least suggested the issue was likely to to with one or more apps rather than something inherently wrong with the phone.
GSam Battery Monitor wasn't much use. All it told me was that Google Services or Google Play Services was draining the battery but it didn't tell me which app(s) were causing that.
So I opted for a factory reset of the phone data and installed apps manually, just one or two at a time, watching the battery drain in Settings > Battery to make sure the newly installed app wasn't suddenly increasing battery drain. I'd wait at least 12 hours before installing another one or two apps. So this approach takes a lot of patience and isn't very practical if you use your phone for many things in the mean time. But now my battery life has increased from just half a day to 4 to 5 days...
[](https://i.stack.imgur.com/BjvNL.png)
I don't know whether this could've been fixed without a factory reset, or what app or setting caused the battery drain to increase suddenly in the first place. Ideally there would be some way of getting a breakdown of battery drain within Google (Play) Services due to different apps invoking it.

So you can either (a) not use Google Now (b) be annoyed with trashy clickbait "stories" (c) allow Google to see, save, and track all of your searches and browsing history or (d) start a class-action lawsuit.

2016/03/22 | 504 | 2,016 | <issue_start>username_0: I want to make a wifi hotspot because there is no internet access where I live. I rooted the phone using kingroot.
I started searching for a good app to use and figured I'd start with FoxFi which seemed to have a decent reputation. Got it installed, tryed to start it up and it tells me within 30 seconds to "turn on my mobile hotspot function" on my phone.
Since my particular model doesn't have that standard, after searching I came across a workaround by downloading a hotspot toggle widget. Tryed again, FoxFi seemed to be satisfied with that widget being used in place of an OEM toggle.
Attempted to connect to the new wifi hotspot using my pc and it would not identify the network, thus resulting in no internet connection. So I figured there was a problem with FoxFi and my phone and must've tried at least 10 other wifi hotspot apps both with root and without with good reviews. Still, to no avail has any one worked, most just crashed, another had the same issue as foxfi.
I'd greatly appreciate any help, I have been trying to figure this out for the last 10 hours and am at a loss. If it matters, it's a straight talk phone running off of a verizon network, but I do believe that is the only option for this particular model of the samsung galaxy core prime, being the S82OL version.<issue_comment>username_1: As @Avinash had commented, WiFi Tethering is available on all phones, including mine, which is also a Samsung Galaxy Core Prime (but has a different Model Number).
Were you able to at least connect to your hotspot, by your PC, even without a Network Connection (Internet Access)?
If so, then you would have to enable your "Mobile Data" or "Data Connection" to be able to connect to the internet.

2016/03/22 | 479 | 1,992 | <issue_start>username_0: Since cell phones can call 911 without a SIM card present, it is clear that they can connect to a cellular network to which they are not subscribed.
Is it possible to use this knowledge to do cell tower location triangulation on Android without having a SIM card present? The use case is location detection when the phone is unable to obtain a GPS lock e.g. while inside a building.<issue_comment>username_1: SIM cards are not required for cellular connection. They are just some sort of ID method.
For example: If a phone has AT&T SIMCard, the configuration in the SIMCard will let it connect to AT&T as an identified (with phone number) user and so the SIMCard can be billed for the usage of service.
However, even without a SIM, a phone will always try and connect to cellular networks. But it will be a, let's say, guest user who can't use any of the services since they can't be billed because they can't be ID'd.
911 however is an exception. All services allow 911 calls regardless if the client is identified or not.
I told all these so you can understand the conception better. Now for the actual question: **It probably can be traced without a SIM as well.** Why probably? Because I don't know for sure nor have I ever heard/seen such a case. But conceptually they should be able to do it since they can also access your phone's IMEI and therefore identify the device and triangulate its signal. It is not something you can do on your own though, it is FBI-class action.
It is completely unrelated to GPS because GPS uses satellite, triangulation uses cell.

2016/03/23 | 1,743 | 7,351 | <issue_start>username_0: Disclaimer: I'm not in any way connected to the Greenify developers, nor am I trying to promote Greenify or anything. I'm actually interested in the answers to these questions.
I've found that with a lot of Android devices that I have managed, they become slower the more apps one installs on them. This is especially true with apps that perform some sort of tasks in the background. Often, devices can become so slow that they are a real pain to use.
The solution I found to this was an app called [Greenify](https://play.google.com/store/apps/details?id=com.oasisfeng.greenify&hl=en), that I use with root privileges and an Xposed module. I find that I can keep all the apps on the devices, but "Greenify" all of them. (I think this means that inactive apps are consistently "hibernated" or deprived of system resources, leaving the resources available for active apps.) This usually makes the device much snappier, yet I find that the impeding effect on the functionality of the apps is quite minimal. Needless to say, I consider Greenify a must, especially on devices with lots of resource hogging apps and/or limited hardware.
1. Does Android do something similar to Greenify natively? (Depriving background apps of resources in order to free it up for active apps?)
2. If yes, how is Greenify different from Android's native resource management?
I find that lots of people have Android devices that tend to slow down over time, and many of them end up just buying a new, more powerful device once every few years. But if they used Greenify (or something similar), they might have been satisfied with the performance of the older device for many, many more years. I for example, have a five year old phone, have tons of apps on it, and am quite happy with its performance when using Greenify. However, without Greenify (and *with* all my apps), the phone is so slow that it's barely usable.
3. Is there any native Android way to prevent apps from running in the background and hogging system resources?
For example, in GNU/Linux distros like Debian and Ubuntu, apps don't run or consume any resources at all unless you explicitly launch them (or have them set to launch at startup.) It's the same with OS X and Windows. And when you shut a program completely down, it can no longer consume any resources. I think even iOS automatically kills background apps when it needs the resources for something else.
I've used manual task killers, but after a while, I find that all the apps are back up running in the background again, even if I haven't launched them at all.
4. Is it true that Android is somewhat unique in allowing apps to run in the background, consuming resources?<issue_comment>username_1: 1. Android actually closes some background apps, but only when system ressources are missing (you open a massive game, for example)
2. Greenify differ from the Android memory management by the fact that it kills all apps you specified at will or after a certain time, not only when ressources are missing.
3. Nope. If some system apps that you do not use are running in background, you can disable them or remove them completely with a root app or the `adb shell`
4. Here's the list of things that I know can start a background activity and keep it opened:
* The apps can start an activity automatically at system startup with a permission.
* It can also start one when opened.
* A vulnerability in Android 4.3 and before allows app to keep them active, even when the Android task killer tries to kill apps, but Greenify can workaround this (see the experimental settings).
And @DeathMaskSalesman, a [HTC Wildfire S](http://www.gsmarena.com/htc_wildfire_s-3777.php) running KitKat **needs** Greenify, or else it'll run incredibely slow and drain a lot of battery, more than what needed to start an app.

As far as technical implementation goes, **the system calls into apps** to let them know that they need to release memory or risk being killed:

So to directly answer your questions:
1. No, Android does not clean anything up *for* apps, but it lets them know to do so themselves and kills them if they don't (or if it's not enough).
2. Greenify appears to do "on-the-fly" disabling of apps, so it is not allowed to run anything when in the background (and can't be started automatically when not running), but can still do anything when in the foreground. This is completely different from how Android does it as you see above.
3. Yes — disable them (from Settings → Applications → ) (though you will have to re-enable when you want to run them manually). Or, for those that don't have automatically restarting services, simply kill them (i.e., long press the Menu button and swipe them away). The latter will not prevent them from restarting if the system delivers an Intent to them, etc.
4. No, not at all. True multitasking has long been available on mobile devices — the original iPhone was an oddity when it launched without that ability.

2016/03/23 | 839 | 3,371 | <issue_start>username_0: I've just come upon several `.apk` files hosted with Github projects which are "compiled for debug" (i.e. having `application-debuggable` set, which one can e.g. check using `aapt dump badging /path/to/apk | grep debuggable`. Not being an Android dev, I only have vague ideas what that is for (extended debugging via ADB) – but that's not the question here.
**My question is from a *pure end-user perspective:* What are the (security) implications of installing/using such an app? What are the risks one must be aware of?**
Of course I searched the web for hints on this, but again only got vague hints like "thou shalt not", and "for a release this should be switched off" – no reasons, no background. For that one could think "obviously no big deal" – but notes like *Do spend some time thinking about the security implications for your users* in this context (see [this answer](https://stackoverflow.com/a/15392081/2533433) at SO) suggest differently.
Can anyone here provide some insights?<issue_comment>username_1: There aren't really any *innate* problems with running a debug app. If someone grabs your unlocked phone, enables Developer Mode, and starts debugging they might be able to grab sensitive information from the app's memory slightly more easily — but that's not particularly realistic and easily countered with a lock screen.
Debug information will also make it harder to make use of security through obscurity, which we all know is not real security. This obviously isn't even a factor when it comes to open-source apps, since they can simply inspect the source to find a flaw.
However, the specifics of what code paths you've added for debugging can definitely be security holes. Maybe for testing and verification purposes, the debug version writes the user's password out to logcat when they sign in, for example. There is a great deal of PII that could be exposed this way.
For an end user, all that you know is that it's *probably more likely* for an arbitrary app to leak information if it's a debug version. Unless you are searching for it yourself, you're not likely to see it. That's probably enough reason to avoid such apps — doubly so since a developer who doesn't know the difference between Release and Debug versions is probably not protecting your data very competently either.
<NAME> also [made a good point in chat](http://chat.stackexchange.com/transcript/message/28480273#28480273): A debug version probably won't be properly signed, meaning that it could be "upgraded" from a malicious source. I would again presume this to be an unlikely occurrence, but it is another point against it.

So actually, if your device is not rooted and you rely on `adb backup` for your backups (e.g. if you do not use Google's cloud backup, and your ROM has no support for [Seedvault](https://calyxinstitute.org/projects/seedvault-encrypted-backup-for-android)¹ built in), you might actually wish this to be set.
¹ Seedvault comes included e.g. with LineageOS since Android 10, and also with some other custom ROMs

2016/03/24 | 791 | 2,781 | <issue_start>username_0: I've been having trouble with my phone lately so I decided to back up my data and factory reset, but every time I want to do it the "reset phone" button does not work, I can't even press it. I have also tried to hard reset but when I get to the screen where I choose factory reset (the screen where there is a android guy saying "no commands"), there are no commands to choose so that is also a negative for resetting.<issue_comment>username_1: don't worry. Do just what I say:
1. Turn off you Motorola Moto G 2nd Gen(I mean moto G2).
2. Afterwards press and hold the `Volume Up` and `Volume Down` for about 2-3 seconds.
3. While still holding these keys press the `Power` button for a short while and release all buttons.
[](https://i.stack.imgur.com/HjOgU.jpg)
4. Then select option Recovery by using to navigate `Volume Down`, and to confirm Volume Up.
5. In the next step hold down the `Volume Up` for a few seconds when an Android logo appears on the screen.
6. While holding the `Power` button, press and release the `Volume Up` key.
7. Press `Volume Down` to choose "wipe data/factory reset", and then push the `Power` button to confirm.
8. Select "Yes--delete all user data". Use `Volume Down` button to scroll and `Power` button to select.
9. To restart the phone, select "reboot system now".

Then enter fastboot and on your computer write:

What is the exact difference between the two?<issue_comment>username_1: I had read about this in Google forums I think but can't locate. However [here](http://thetechportal.in/2015/12/08/google-calendar-gets-reminders/) is an article that explains the difference. More details in the article
>
> Google explains that the difference between Events and Reminders is that the former is deleted irrespective of whether the event was attended or not. Reminders on the other hand shows up in Calendar until the task is accomplished — and yea, that’s pretty much the literature difference between the two, so nothing new here Google!
>
>
> Until a reminder is completed users will be notified of the task by a message displayed on top of Google Calendar. Once the user has finished the task, the reminder can be swiped away from notification area. If you feel that this is a bit irritating then you can set the Reminder to a later time, similar to Events.

Upvotes: 4 [selected_answer]<issue_comment>username_2: In Android 6 I can see that reminders have less possible configuration options. They both share *Name*, *Location* and *start time*, while they differ in:
Reminder:
* One alarm
Event
* Date and time of the end of the event
* Contacts in the event
* Zero or more alarms
* Notes
Upvotes: 2 <issue_comment>username_3: To keep my Calendar Events and Reminders clear, I tend to think of calendar events as a fixed time and/or place, where reminders are flexible in the “manditoryness”, time, or place to be done.
Upvotes: 1 <issue_comment>username_4: I use "Events" for date/time specific happenings, and enjoy the fact that they stay listed, and can serve as a record of how I spent my time that day (I tend to delete things I don't end up doing). "Reminders" are cool, bc first of all they have a little finger with a string around it as the icon, and I set them to appear when I want to have my memory jogged about something that needs to be done (serves me kind of like a post-it note): i.e., set out the trash barrels, buy a birthday gift for my niece, etc.
Where I think the mix-up can happen, is that Events can be listed, and within the entry box one can set a reminder notification to pop-up 10 min, 30min, 1 hour before the actual event start time.

But, when I do that, Bluestacks says the software is corrupt and I need to redownload Bluestacks from their website.
What can I do to change the location of Bluestacks?<issue_comment>username_1: You should use a directory junction, which will make the old folder point to the new one (and automatically work when the old one is accessed as normal).
1. Fully exit Bluestacks
2. Move `C:\Program Files\Bluestacks` to `D:\Bluestacks\Files` (for example)
3. Likewise, move `C:\ProgramData\Bluestacks` to `D:\Bluestacks\Data`
4. Open a Command Prompt and run:
```
mklink /D /J "C:\Program Files\Bluestacks" D:\Bluestacks\Files
mklink /D /J "C:\ProgramData\Bluestacks" D:\Bluestacks\Data
```
5. Repeat similarly for any other directories you might need to move
Upvotes: 2 <issue_comment>username_2: I had a problem and received the message "The syntax of the command is incorrect."
So, for directory path with gap, it is necessary to use quotation marks.
For example: (link is first, target is second)
`mklink /D /J "c:\Users\All Users\BlueStacks" "d:\_ProgramFiles\BlueStacks"`
Junction created for c:\Users\All Users\BlueStacks <<===>> d:\_ProgramFiles\BlueStacks

Go back one screen and you have a new menu option for "Developer Option" tap that and turn on USB debugging.
Google for "Android File Transfer". Install and open the app, connect your phone to the mac.
a directory browser will show up and copying files is as easy and drag and drop.

Does that mean they can go at my personal photos and send it back to themselves?
Sorry if it's a bit paranoid but I don't like people stealing my photos.<issue_comment>username_1: Yes, this is the "Access external storage" permission which gives apps access to access your internal and/or external `/sdcard` space. Your photos are typical stored under `/sdcard/DCIM/` or `/sdcard/Photos/`, etc.

But the good news is that new android updates allows us to disable these permissions later on by going to our Settings and Apps.
I hope this might help you in disabling the app permissions

suddenly stopped fast charging. and when i say "stopped fast charging," i mean charges slower than molasses now. takes literally about 4hrs to charge from 80% to 100%.
tried multiple known good chargers and cables and verified with both another s5 and s6 activ. found that the computer won't recognize it anymore magically.
i am rooted and have uninstalled a bunch of bloat. shouldn't matter right?
also in developer options- i can check usb debugging, but then in the secret menu (\*0#\*0) or whatever, mtp+adb is unchecked. if i check that, then go back to developer options, usb debugging is unchecked.

If you have replaced this on purpose with a custom binary, then you needed to run a

adb shell chmod 0755 /system/bin/sh

Adb Shell Might work because you have replaced the shell in system, You can run a remote shell command..

2016/03/29 | 1,234 | 4,972 | <issue_start>username_0: I'm using a Using Samsung Galaxy S7, Android 6.0.1. and I'm having trouble using apps in parallel. Here's what triggered this post:
I got myself and [iRig2](http://www.ikmultimedia.com/products/irig2/) to practice playing guitar silently, downloaded AmpliTube, plugged in the guitar and it worked, I could hear my guitar back and apply effects, change amps, etc..
On to the next step, to play over backing tracks. IK Multimedia advises to use apps like [Riff Maestro](http://www.ikmultimedia.com/news/?item_id=7692) with AmpliTube running in the background. And this is precisely my problem, **I can't get AmpliTube to keep running on the background!**
Here's what I tried so far:
Test 1:
* open AmpliTube (app), plug in the guitar and check it's working. If it is:
* press home button
* open Riff Maestro (app)
* as soon as I click the home button, AmpliTube stops sending guitar sound out
Test 2:
* open AmpliTube (app), plug in the guitar and check it's working. If it is:
* press the home button (AmpliTube stops sending sound out, as per Test 1)
* open Riff Maestro (app)
* press the "Recent applications" button
* swap to AmpliTube, it starts sending guitar sound again
* press the "Recent applications" button again to swap for Riff Maestro
* AmpliTube stops sending sound again
I tried splitting the screen but none of the apps supports split screen.
The question is, how can I get 2 apps (in this case AmpliTube and Riff Maestro) working simultaneously so I can hear my guitar on AmpliTube AND play a back track on Riff Maestro?
Many thanks in advance!<issue_comment>username_1: That's a really good question! Thank you for asking it though.
On Android Programming, There is something we call, [**`Activities LifeCycle`**](http://developer.android.com/guide/components/activities.html#ImplementingLifecycleCallbacks)
Imagine, when you pressed the home `Button`, The current `Activity` is going to `onPause()` method which it stops the `Activity` and it's not longer active because this is the Android `Activity`'s lifecycle.
So, for better underestanding, The developer or those Application's programmers have to use something like [**`Services`**](http://developer.android.com/guide/components/services.html) which it can perform ***long-running operations*** in **the background** and does not provide a user interface.
And after that, you should be able to use those features together.
Upvotes: 1 <issue_comment>username_2: tl;dr
=====
* Get a device with multi-window support. Recent Samsung devices have this feature. The upcoming Android 'N' will support this as well.
* Use apps that run in the background, or use apps that work with the above multi-window support (and if the two you want to use don't do either, you're SOL)
Long explanation
================
Android traditionally only allows one foreground app to be displayed at a time.
But apps (if the developer of the app chooses) can run in the background, as long as a UI is not required. For example, a music app playing music but leaving only a notification as a UI.
There is a special permission to allow some apps to 'paint' on top of the current foreground with their UI, but those are rare, and again, require the developer to enable and use the feature. Most don't use that unless they are trying to make some always-on-top widget UI, like a 'most recent contacts' widget that Samsung uses for example.
Some devices customize the Android OS code and do allow for multiple apps to run side by side. For example, most Samsung devices running Android 5+ allow for multiple apps to run side-by-side, but it depends on a few things outside your control for them to really work together. Among them, for example, if they are audio apps, they both need to support *not* requesting exclusive audio access; otherwise one will mute (or at least 'duck') the other.
The upcoming Android 'N' version is going to support multiple app 'windows' a little better than the Samsung hack, but it is still in Preview (at this time) and therefore not on any production device for you to use. They will still probably have the same limitations that the two apps may or may not work together, depending on the apps.
All that to say, it is *possible* for multiple apps to work side-by-side together, but it is rare and there isn't much you, as a consumer, can do about it for now. The best you can do is try a recent Samsung device or wait for Android 'N', while hunting for apps by trial and error that happen to work together like this. But there are no guarantees since it is such a new feature in the Android ecosystem.
In this particular case, since you say you've tried the screen-splitting feature with the two apps, your only solution is to petition the app developers to support this behavior. It is up to those two developers to change their code to enable background audio and/or UI support, or to work with the new split window features better.

2016/03/29 | 558 | 2,302 | <issue_start>username_0: I want an app that can hide/encrypt selected pictures and video on the external memory card without moving them to internal storage where space is at a premium. This is the problem with Keepsafe and other popular apps in this category. I have rooted my phone & am using the Xposed media scanner module to exclude a hidden directory on the memory card, and done the `platform.xml` workaround to make the external card writable.
I've also wanted to try the symbolic link trick by placing the files on an ext2 formatted partition on the memory card used for link2sd and then `ln -sf` from the internal storage, but that doesn't work either. The media scanner exclusion works, but the files themselves are still readable on the memory card. Is there any app, even a root requiring one, that can encrypt or hide the files as they are despite the stupid restrictions put in since Kitkat?<issue_comment>username_1: I believe [SECRECY](https://forum.xda-developers.com/android/apps-games/app-secrecy-t3660053) will do what you want; I haven't used it for a while, but from what I remember it encrypts files on the SD card and doesn't need root.
Note: the app is no longer available on Play Store and the link directs to XDA Forums.
Upvotes: 2 [selected_answer]<issue_comment>username_2: by renaming a file from filename.txt to .filename.txt (add a dot "." before the name) you will hide the file. I.e. it will not show up on any file explorer, (unless it is set to show hidden files.)
If you want to hide, say movie files from appearing in your media player, or music files from appearing in your music player, or even photos from appearingin your gallery, (or any other type of file from showing in an app except a file explorer), you can change the file extention to anything else or remove it completely.
I recommend just changing the dot "." to a blank space, that way you can still identify the file yourself and you wont forget the file extension in case you ever need it.
like so: from "filename.avi" to "filename avi".

2016/03/30 | 655 | 2,481 | <issue_start>username_0: I know of 2 networks with the same SSID but different credentials (via a "sign in to network" webpage). I only have an account for one of them (and it happens to be somewhere with little-to-no 3G/4G so I can't just turn this network off completely). Of course, when it connects to the network I can't use, it turns off my 4G.
I've seen [this answer](https://android.stackexchange.com/a/130683/44734) suggesting it could be done using `tasker`. I don't currently have tasker but could buy it for this. But I have a few issues with that approach:
* I don't really want my GPS polling all the time for (mainly) battery life reasons.
* So: Will tasker do this with network-based locations (especially as one location has poor mobile signal - the same place is inside a big building so GPS might not work)?
* The answer I've linked to wasn't accepted despite seeming to answer the question pretty well, and has no upvotes. It doesn't make me confident it would work.

Note: the app is no longer available on Play Store and the link directs to XDA Forums.
Upvotes: 2 [selected_answer]<issue_comment>username_2: by renaming a file from filename.txt to .filename.txt (add a dot "." before the name) you will hide the file. I.e. it will not show up on any file explorer, (unless it is set to show hidden files.)
If you want to hide, say movie files from appearing in your media player, or music files from appearing in your music player, or even photos from appearingin your gallery, (or any other type of file from showing in an app except a file explorer), you can change the file extention to anything else or remove it completely.
I recommend just changing the dot "." to a blank space, that way you can still identify the file yourself and you wont forget the file extension in case you ever need it.
like so: from "filename.avi" to "filename avi".

However, it is saved on his android phone so he can access it on his phone, but not on a laptop he wishes to set up. I suggested he create a new gmail account and autoforward all mail from his current gmail (via his android phone) to his new gmail account.
How can he do this from his android gmail app? I can't find a universal forwarding option for mail to the account.<issue_comment>username_1: Unfortunately, there is no option like this in the gmail app. You would have to log in on the website to change it, maybe the login is saved in the chrome app, so you can set up the automated forwarding there.
You can even set up another e-mail in the accounts settings of your google account, where you could recover the mails. Just go to accounts.google.com on the phone and there you can set up a lot.
But only, if the password is saved.
The only solution if the password is not saved would be:
* forward every existing mail to the new mail account
* create an automated answer for the old account with the new mailadress inside
* keep the old account still in gmail in case of any important mails
* transfer the accounts, which are linked to the old mail adress to the new by entering a new mailadress in the respective accounts (i.e. banking, news, amazon and so on)

If you're not familiar with it, it essentially allowed you to tap a button to instantly turn your internal storage into a drive on your local network. You could then go into Windows Explorer, type in the local IP and password Wireless Storage provided, and be able to browse your phone exactly as if it was connected over MTP/USB or Bluetooth (but in my experience, I found it to be far faster and more reliable).
Now that I have a Galaxy Note 5, is there any way to recreate that same wireless storage feature, or at least come close to how seamlessly it worked?<issue_comment>username_1: Unfortunately, there is no option like this in the gmail app. You would have to log in on the website to change it, maybe the login is saved in the chrome app, so you can set up the automated forwarding there.

2016/03/31 | 1,758 | 6,257 | <issue_start>username_0: The mediaserver in my stock and rooted Android 6.0.1 (running in Nexus 6) doesn't detect new files created or moved to into /sdcard using adb. It doesn't detect until I do a soft/full reboot which I find unacceptable to perform.
I'm able to manually run mediaserver using command-line to begin file scanning again# *and I want this to be done automatically and immediately whenever a new file is created under /sdcard*. At the moment, I have Tasker run the mediaserver whenever USB cable is unplugged.\*
The obvious choice here seems to be an automation app of which I tried Tasker and [Automate](https://play.google.com/store/apps/details?id=com.llamalab.automate), and both amazingly failed to detect new files, particularly under /sdcard/Music, when created through adb. However, if an app created files in any directory under */sdcard* those two apps immediately detected the changes. I also tried pushing files to */storage/emulated/0/* instead of */sdcard/* and made corresponding changes in those two apps' triggers.That step didn't benefit me.
It is to be noted that I observed this problem in stock Android 5.1.1 and a CM13 snapshot build as well.
So, how do I achieve the goal?
### Update
I'm aware of the possibility of creating an alias in the OS running in my PC which would execute a script providing a way to push the file as well as run the mediaserver. However, it is something I would like to avoid as much as possible.
\* I was using it but later switched to a script executed from PC using an alias. However, ***I do not want to depend upon any of the two methods***. My fingers are comfortable with typing *adb push* instead of *adb\_push* or some other but single word.
### Update 2
* I do not intend to restrict myself to a particular directory, such as Download and neither pushing files into the latter actually works.
* I would like to stress that I'm not asking for *how to run mediaserver*. That I already know. All I'm looking for is: Whenever I do `adb push FILE /sdcard/FILE` the mediaserver should automatically and immediately kick in and scans the file. Regardless of any perceivable performance issue, I want it to kick in every single time.
### Update 3
Okay, *I may be using an incorrect term*. Perhaps *mediaserver* and *media scanner* are terms for two different things in Android. In the case of confusion, please stick with
"media scanner" for both the current revision and the bounty note.
### Update 4
# Courtesy of androidyue for [this helpful resource](http://droidyue.com/blog/2014/01/19/scan-media-files-in-android/), any of the following command in preformatted text is what I can use in my device to make media scanner scan the file.
```
# FILE_PATH refers to the location of pushed file in Android. E.g. /sdcard/Music/lolcat.mp3
am broadcast -a android.intent.action.BOOT_COMPLETED -n com.android.providers.media/.MediaScannerReceiver
am broadcast -a android.intent.action.MEDIA_SCANNER_SCAN_FILE -d file://FILE_PATH # guaranteed to work. See https://goo.gl/lH0CLT for proof.
am broadcast -a android.intent.action.MEDIA_MOUNTED -d file://FILE_PATH
```
### Update 5
Per the [suggestion](https://android.stackexchange.com/questions/141142/making-mediaserver-immediately-scan-a-file-created-through-adb?noredirect=1#comment182420_141142) from Manubhargav, I tried Sarkie's MTPFix available [here](https://github.com/Sarkie/mtpfix/tree/master/release). It didn't work, both in stock Android 6.0.1 and CM13. I saw the following entry when I enabled the service for that app.
```
04-07 09:38:14.771 3383 3383 I MTPService: Watching /storage/emulated/0
```
I later pushed a sound file into */storage/emulated/0/* and nothing showed up in my music player. Logcat also didn't display anything useful either.
By the way, this app [uses FileObserver](https://github.com/Sarkie/mtpfix/blob/master/app/src/main/java/org/sarkie/utils/RecursiveFileObserver.java), so I'm not surprised if it couldn't detect files created using adb, since it is the same issue with the automation apps I tried.

Try using Download folder inside Internal Storage as the absolute path
Upvotes: 0 <issue_comment>username_2: Okay, it seems the answer is trivial. My fingers don't have to lose the comfort of typing `adb push`, yet I would be able to cause media scanner scan my pushed file, *automatically and immediately*. Here's my script tweaked to my needs:
(**Note**: root access is *not* required in Android)
```
#!/bin/bash
function push_file () {
target="${@: -1}";
file_path="${@: -2:1}";
[[ "$prog_bar" == "-p" ]] && adb "$@" || $call_adb push -p "$file_path" "$target";
}
function broadcast () {
file_name="$(basename "$file_path")";
[[ `echo "${target: -1}"` != "/" ]] && unset file_name;
[[ `echo "${target:0:1}"` != "/" ]] && target="/${target}";
$call_adb shell 'am broadcast -a android.intent.action.MEDIA_SCANNER_SCAN_FILE -d '"\"file://$target$file_name\""'' > /dev/null;
}
if [[ "$1" == "-s" ]]; then
if [[ "$3" == "push" ]]; then
prog_bar="$4";
call_adb="adb -s $2";
push_file "$@" && broadcast;
else
adb "$@";
fi
elif [[ "$1" == "push" ]]; then
prog_bar="$2";
call_adb="adb";
push_file "$@" && broadcast;
else
adb "$@";
fi
```
I then setup an alias named *adb* in *.bashrc* like this:
```
alias adb='bash FILE' # FILE refers the file path of the said script
```
This was possible thanks to the very helpful article: [Handling positional parameters](http://wiki.bash-hackers.org/scripting/posparams#mass_usage) at Bash Hackers Wiki.
**Note**: the script more or less requires a \*nix based OS in PC with version 4.x of Bash installed and support for *.bashrc*. If you intend to use the script, you're encouraged to edit it to suit your working style.

search for and install universal adb driver
or your devices adb driver !
Once installed,
Wait for the bootloop and run this command in adb via command terminal (cmd)
```
adb devices
```
Does your device show up on pc ?
if it does show up, type
```
adb kill-server
adb root
adb shell
su
busybox rm /system/
```
rm will remove the file specified, in this case it's the boot animation file ... Once removed, your device will boot with a stock android logo or a blank screen !

In the output locate the string *Configured networks*. Following that would be the info on all the saved Wi-Fi networks in your device.

Any solution to this without rooting the phone?<issue_comment>username_1: As per [this post](http://forums.androidcentral.com/samsung-galaxy-note-5/587616-miss-menu-button.html#post4715333), go to Settings → Accessibility → Dexterity and Interaction → turn on the Assistant Menu.

[Samsung also says](http://www.samsung.com/us/support/answer/ANS00042217/997353289/) "In certain applications, you can touch and hold the Recent Apps button to view the Menu options." This is probably limited to newer apps as well which is why it didn't work for you.

I have my own personal SIM which I have a contract that gives me unlimited calls. What I would like to do is get another SIM as a work number to give to clients. To keep this SIM active I just want to pay the minimum amount (I think it is 10 Euro every 6 months or something like that) so that clients phone my work SIM and not have my personal number.
With having unlimited calls on my personal SIM I'd like to phone my clients back using my personal SIM as it costs me nothing extra but make it look like I'm phoning from my work SIM.
Is it possible to do this? Is there an app that can control this?
I could always just phone my clients using my personal SIM and withhold my number so my number doesn't show but that's not really what I'm after.
Does anyone know is this possible?
Thank you<issue_comment>username_1: Using a redirection service, you can do this,
Remember that changing a number may be ILLEGAL depending on the area you live in.
In most scenarios it's only calling someone from an unauthorized number,
So it's good to find someone that actually owns the number they are trying to identify as...

I do this when travelling overseas, my outgoing calls say they are my US number. I let incoming calls just go to voice mail of my real cell phone number so I don't have to pay international fees, and immediately call people back using skype out. My clients never have to know I'm out of the country.

Is there any way to run those apps.

Remember that changing a number may be ILLEGAL depending on the area you live in.
In most scenarios it's only calling someone from an unauthorized number,

Is it possible to do insert inlined images directly on Gmail?<issue_comment>username_1: To send a photo on Gmail using the Android app:
1. Save the photo that you want to send to a local folder on your phone.
2. While composing a message or reply, tap the attachment paperclip icon () at the top of the Gmail app and select "Attach file" from the menu that appears.
[](https://i.stack.imgur.com/aYYRw.png)
3. Select the photo that you want to send from a local folder on your phone. This photo is sent inline. If you selected a photo from anywhere else except for a local folder on your phone it would be sent as an attachment instead of inline.

1. Open Google Docs
2. Open a new Word document
3. Select "Insert image" and insert the image of your choice
4. Once done, it is now in clipboard form, copy that

2016/04/03 | 400 | 1,695 | <issue_start>username_0: I have a galaxy s6 with Verizon on marshmallow, and every time I try to toggle wifi from the lock screen I am forced to unlock the phone. This isn't really a hassle, more of a minor inconvenience, but it doesn't make sense that Samsung would design the lock screen like that. I know the iPhone has excellent security, and it doesn't require the phone to be unlocked to toggle wifi, so this isn't a security measure. This also happened in lollipop. Thanks in advance for any ideas.<issue_comment>username_1: This is just the way Samsung chose to implement it... The quick toggle panel on most stock Android or near-stock devices is accessible without unlocking the device, although anything other than a toggle, such as selecting a different WiFi network, requires unlocking.
You would need to flash a custom ROM in order to get the desired result due to Samsung's customizations being so non-standard.

You might need a rooted device to change the DNS.
An universal method to change the DNS is by using an app like **[SetDNS](https://play.google.com/store/apps/details?id=uk.co.mytechie.setDNS&hl=en)** or **[OverrideDNS](https://www.google.com/search?q=Override+DNS+apk)**.
Other methods for changing DNS is available here:
**[(GUIDE) How to Change DNS in Android Device (7 methods)](http://forum.xda-developers.com/general/xda-university/guide-how-to-change-dns-android-device-t3273769)**
A few DNS servers that don't resolve porn websites are:
1. OpenDNS:
172.16.17.32
192.168.3.11
2. Norton:
172.16.31.10
192.168.127.12

2016/04/03 | 826 | 3,377 | <issue_start>username_0: There are two types of boot animation:
1. Company-brand logo
2. ROM-based
I was able to change ROM-based animation by rooting the phone and using a custom ROM.
However, I'm a bit confused about how to change or remove the brand logo animation. Is it safe to do that? Will it increase the speed of the booting process?<issue_comment>username_1: Yes it is possible to change the company logo. If you have ever flashed a custom ROM which changes it and still have the `update.zip` file lying around, sometimes (after extraction) you will find a logo.bin (its a *raw* Binary file) file in the root directory. This file contains the Brand Logo as well as the charging animation and the image to be displayed in fastboot mode. However on your phone (and most other phones) there is no logo.bin file but just a partition named `LOGO` where a complete dump of the logo.bin file is saved.
There are `update.zips` just for changing your phone branding, however only files for the correct resolution and chipset will display correctly. (Yes, you can indeed use such files made for other phones with the same SoC with the same resolution)
Upvotes: 3 <issue_comment>username_2: I have a very different take on this matter than @username_1. Note a few things first and then decide whether doing this is worth it:
* The *boot logo* is a actually a raw binary image, constrained by size, not format.
* The format of the bootloader splash screen, as it is known, varies for even models of the same device (case in point, Exynos and Qualcomm Samsung Galaxy models).
* On Qualcomm devices, the bootloader splash logo is typically stored on a partition called `splash` or `logo`, to change which you need to flash as similarly named `.mbn` or `.bin` file (not `.img`)
* If you don't choose a logo with a format and size specific to your device, it may result in unforeseen circumstances (read, what will appear to be a **Hard Brick**, the device not booting up at all). Why? The bootloader is dumb and will try to load whatever is on the splash partition as long as it fits in there (i.e., has a specific size). It might not even be a picture at all. The bootloader may choose to 'panic', i.e., show some error message and reboot, keep trying to reload the splash, or continue booting the OS. You can hope for the last, but you never know unless someone has documented the specific behaviour for your device or you learn it the hard way. You may or may not lose your charging screen, however.
* Do you still want to do this? I don't know of a guide specific to your device, let that put you off a bit. If there is indeed an acceptable splash file for your device, just `fastboot flash` the image file (note, *image* as in *disk image*, not *photograph*) to whichever of the above 2 mentioned splash partitions which exists on your device. This can be done on some HTC, LG and Nexus devices with Qualcomm or Tegra chipsets.
* A last FYI, the manufacturer may choose to integrate the logo into the bootloader (`aboot`). I know Xiaomi does this for some devices (Redmi 1s and Redmi 2 - personal experience), it's probably true in your case too. Then you will need a **custom bootloader**, with the splash screen packed into the bootloader flashable image file (*image* as above).
Still there? I can't help you beyond discouraging you, so...

2016/04/03 | 907 | 3,180 | <issue_start>username_0: I would like to know how to root Cyanogen OS on WileyFox Swift<issue_comment>username_1: Simply by flashing [SuperSU](https://download.chainfire.eu/696/supersu/ "chainfire: SuperSU download").**1** There's a [thread at XDA](http://forum.xda-developers.com/wileyfox-swift/general/root-wileyfox-swift-t3261321 "XDA: Root Wileyfox Swift") explaining the steps:
1. download SuperSu
2. save it to your external sdcard
3. enable developer options (settings - about - click mutliple times on the build number)
4. enable OEM unlock in the developer options settings on the device
5. reboot Wileyfox Swift into fastboot mode: with the device powered down, hold the `Volume Up` and connect USB
6. to unlock the boot loader **(WARNING!!! This wipes your user data!!!),** type from your computer:
```
fastboot oem unlock
fastboot -i 0x2970 oem unlock-go
fastboot oem unlock-go
```
7. download latest recovery image [from Cyanogen](http://download.cyanogenmod.org/?device=crackling "Cyanogen: Downloads for Wilefox Swift")
8. to boot the custom recovery, on your computer type
```
fastboot boot .img
```
9. install supersu update zip from recovery menu (choose zip from extenal SD)
10. reboot and enjoy root access
Note that steps 6 and 8 require the matching drivers being installed on your computer if you run Windows.
### Updating a rooted Swift
Also note that "incremental updates" are no longer working with the device rooted. Please see [how to update rooted fox](http://forum.xda-developers.com/wileyfox-swift/general/rom-wileyfox-swift-t3267037) at XDA for alternatives. Each of those updates will probably break root, so you'll have to repeat the above procedure after each update to regain root access.
Alternatively, you can also switch from *CyanogenOS* to [CyanogenMod](https://download.cyanogenmod.org/?device=crackling&type=snapshot "CyanogenMod (stable) for the Wileyfox Swift"), which includes root access.
---
**1:** Note that's not the latest version – but the one reported working at the time of that post. The always [latest version is available here](http://download.chainfire.eu/supersu "chainfire: download latest SuperSU").
Upvotes: 4 [selected_answer]<issue_comment>username_2: Izzy's answer is great. A couple of additions - I hit an issue where my device would not Boot past the TWRP Recovery tool. If you hit the same roadblocks make sure:
* **Use TWRP version 3.2.0.4 or newer**. The previous version I used did not work. You can choose your Custom Recovery tool. I used TWRP instead of CWM.
* I followed these instructions: <https://www.youtube.com/watch?v=NaK5OxUeDKM>. Key points: Wipe data first, via TWRP. Use **Advanced Wipe** and select **Cache, Dalvik/Art Cache, System** and **Data**
* You can use adb sideload from TWRP (select the Advanced button). Make sure you **install the rooted ROM and the gapps zip files** before you reboot.
If it helps, I was running the non-rooted Cyanogen O/S. You download the rooted version from: `https://download.cyanogenmod.org/?device=crackling`. I found the newest version of TWRP on xda-forums. Then I used adb sideload to get the new version of TWRP onto my device.

2016/04/04 | 1,856 | 6,432 | <issue_start>username_0: I was flashing a **Samsung device** with a single file (`tar.md5` format) and i saw some people are working with 4 files(`Repairing firmware`) to fixing the most and actually, ***Any problems*** with those 4 files and i've heard that they says, it should fix any`(Software)` problems after flashing it on the device but *i couldn't actually* figured out ;
**What is the exactly difference between these two** which the 4 files containts four files such as ;
* `Bootloader` file
* `CODE` file,
* `Modem` file
* and `CSC` file
And the single one has the `Modem` file and the others which we'd introduce it in `PDA` section?
Or, which one should be the best option for updating a device?
Also, i've seen an application which it could convert the `Single firmware` to four files and that was more interesting about the question too!<issue_comment>username_1: * The single file which you can flash (I presume you are using Odin) contains **all the files required** for your firmware upgrade- which you place in PDA option of Odin
* If you want to upgrade the firmware **selectively**, you would use one of the four files mentioned:
+ *Bootloader file*- not normally done for stock, mostly used for compatibility issues in version upgrade in flashing custom ROM. [Example : MJ5 bootloader](http://techbeasts.com/2014/11/03/install-ditto-note-4dn4-rom-on-galaxy-note-2-and-get-all-note-4-features/) for flashing Note 4 ROM on Note 2
+ *Code File* is typically the ROM
+ *Modem File* is the radio component of ROM- you may want to replace a ROM meant for use in a different region and change the modem to get better performance by flashing modem file of your region. List of modems for your device can be searched on XDA forums. [Example- Note 2 modems](http://forum.xda-developers.com/showthread.php?t=2044937)
+ *CSC (variously referred to as Country/Carrier/Consumer Specific Code) File* is the file you would want to use to change if you bought the phone in a different region and want to use it in your region (Samsung ROMs incorporate region specific features ) . [Example](http://forum.xda-developers.com/galaxy-s5/general/how-to-change-csc-code-g900h-t3127753)
>
> What is the exactly difference between these two?
>
>

I had overlooked this main question and realised I never probed this aspect. Googling leads me to the conclusion that the key difference is **is it Odin ready (to be flashed as a single file or not?**. While Odin and Kies are both Samsung proprietary, formats required for using them differ. using a Kies format and adapting to Odin requires extraction of files required.
* Samsung firmware upgrade comes as a single file having the necessary files required for upgrade (Odin ready)
* Samsung firmware is available on many sites, [Sammobile](http://www.sammobile.com) is considered to be the most reliable out there. This site and other sites sometimes host upgrades/beta/test mode in *Field Upgrade Serviceable (FUS)* files which are not **standard Odin flash ready files. But they can be flashed using Kies**. Reason cited here for not being able to use directly on Odin is [header file corruption](http://forum.xda-developers.com/showthread.php?t=1611225). These need to be downloaded using apps like [FUS downloader](http://www.jayceooi.com/check-fus-downloader-download-decrypt-latest-samsung-firmware/) and then split into required files to be upgraded using Odin.You put these CSC, modem,bootloader files in the corresponding sections of Odin
Linked site(s) explain (**Warning:** Don't use *PIT* file which is available on splitting till you understand what it is for)
* To summarise, key difference lies in **packaging of firmware (Odin Vs Kies), others being type of firmware (beta/ test/ tested/ leaked) and possible end use (complete or selective upgrade)**
>

It depends on what you want to do-there is no specific answer, as for instance of flashing a modem only explained above. Or if your source upgrade file is Odin ready or not a explained above
If you are using Linux the method varies (not tried by me) and you can pretty much use either methods as outlined [here](http://forum.xda-developers.com/showthread.php?t=1508703)
Samsung has a pretty confusing (till you get hang of it) of breaking down these components and labelling them. You can read [here](http://googleweblight.com/?lite_url=http://boink.pbworks.com/w/page/34198052/Upgrading%2520Android%2520on%2520Samsung%2520Galaxy%2520S&ei=c5gJ9p4t&lc=en-IN&s=1&m=154&host=www.google.co.in&ts=1459772264&sig=APY536woP3dKFswg92zluykYVRa3q_B4SA) and [here](http://googleweblight.com/?lite_url=http://boink.pbworks.com/w/page/34198052/Upgrading%2520Android%2520on%2520Samsung%2520Galaxy%2520S&ei=c5gJ9p4t&lc=en-IN&s=1&m=154&host=www.google.co.in&ts=1459772264&sig=APY536woP3dKFswg92zluykYVRa3q_B4SA) for starters.

The 4 files are called Binary Firmware which contains all the files in certain order:
* Bootloader contains all the boot files
* AP contains all the system and recovery files.
* Modem/CP contains phone network and wifi software.
* CSC contains PIT file and cache removing IMG which puts all the files in order and repairs any damage firmware has before.
Thats why they are called repair files.
Upvotes: 2 <issue_comment>username_3: Some things were not explained. A 4 File is not exactly binary firmware in a sense (even though it's all binary) given that they are used to repair the device. Currently the PDA section when using Odin3 is AP. In the 4 file you will notice a CSC file and a HOME CSC file. If you are flashing there is a difference between the two. The CSC file returns your application data to factory whereas the HOME CSC file saves your appication data. Either one goes only in the CSC section, do not use both at the same time.
The Combination files are binary repair files that fix the binary codes of the device. It is only placed in the AP section of Odin3 when flashing.

Is it really impossible?
Isn't there some kind of workaround?
Update: Apparently ES file explorer can see the disk but can't open it. I heard there are such issues with NTFS hard drives on Android.<issue_comment>username_1: Absolutely possible, I do this almost every day. You need to have an otg dongle (not just a cable) that permits adding an external power source. I use a dongle I bought on amazon for £12 and normal usb battery pack. Then I can load films onto my phone from a 2tb WD passport.
Without the additional power source you are not able to read the drive as your phone (or tablet) can't output enough current to properly operate the HDD.
Upvotes: 4 [selected_answer]<issue_comment>username_2: I read in several places that using hard drives with USB OTG was possible with Samsung Galaxy phones because Samsung reads NTFS-formatted drives. (I have an A9 Pro.)
But while I could use flash drives and micro-SD cards up to 200GB, I could not get NTFS-formatted external hard drive to work, with or without powered hubs.
Until...I prepared a WD Passport 2T drive, yes 2 terabyte.
How did I do it? I reformatted using exFAT. That's it. Then no powered hub, no lag, no overheating. No problems at all.

2016/04/04 | 1,241 | 4,445 | <issue_start>username_0: I've downgraded from Cyanogenmod 13 (Android 6.0.1) to Android stock 5.1.1, and kept my previous mmssms.db file, but it is incompatible with older Android versions. I would like to import this database in an Android Virtual Device running Android 6.0, back it up using SMS Save & Restore, then restore the .xml file produced by that app on my device.
However, when I copy my old **com.android.providers.telephony** directory in the **/data/data/** directory of the AVD, neither the Messenger app, nor SMS Backup & Restore see any message. The directory and its contents are owned by the **radio** user, belong to the radio group, and have **chmod** set to 771.
How can I check what is preventing the system from accessing my database?
Or how else can I retrieve my sms ?<issue_comment>username_1: I've finally managed to restore the contents of my previous database on my current device and I will explain how.
The idea was to copy the backup of **/data/data/com.android.providers.telephony** from my previous installation, to an Android Virtual Device, back it up there using SMS Backup & Restore in XML format, then restore that XML backup on my device. SMS Backup & Restore merged the messages from the backup with the current device's messages so I didn't have to merge the two databases by hand.
In my question, the AVD running 6.0.0 wouldn't read the contents of my database because it was created on CM 13 which is based on Android 6.0.1. But Google doesn't seem to provide an emulator image based on Android 6.0.1, so I still used an AVD running 6.0.0. For performance reasons I've configured it to emulate an **Intel Atom (x86)** CPU and installed Intel HAXM driver on my PC (I've followed [this answer](https://stackoverflow.com/a/13856866/1190096) to do that).
The mmssms.db database holds properties about itself, especially version numbers, so I've edited them to make Android believe that it dealt with a database of a version it could deal with. I've opened mmssms.db in [SQLite Expert](http://www.sqliteexpert.com/), clicked on the "Database" tab, and in the property list, found the following lines:
* schema\_version
* user\_version
I've downgraded these to 44 and 60, respectively.
Then I transferred my backup of **/data/data/com.android.providers.telephony** to the AVD using **adb push**, after making sure that location was already empty there. Using **adb shell** I've set the owner and group of everything in this directory and its subdirectories to **radio**, and in the **database** subdirectory the **chmod** value to 660.
I've rebooted the device.
I've installed SMS Backup & Restore on the AVD through ADB. (The .apk of that app can be found on an existing device in /data/app on a device where it is already installed. I didn't bother installing Google Play Services on the emulator to get it from the Play Store, but you can do that.)
I've backed up the messages and copied the resulting .xml over to my real device, where I've used SMS Backup & Restore to restore it. Voilà.
Upvotes: 3 [selected_answer]<issue_comment>username_2: I had to do an extra step compared to @username_1 answer to get it working with LineageOS 14.1 (original `mmssms.db` came from Android 5.1).
Change the `user_version` from `64` to `68`:
```
sqlite3 mmssms.db
PRAGMA user_version;
PRAGMA user_version = 68;
.q
```
In recovery mode (`adb reboot recovery`):
```
adb push mmssms.db /data/user_de/0/com.android.providers.telephony/databases/
adb shell chown radio:radio /data/user_de/0/com.android.providers.telephony/databases/mmssms.db
adb shell chmod 660 /data/user_de/0/com.android.providers.telephony/databases/mmssms.db
adb shell chcon u:object_r:radio_data_file:s0 /data/user_de/0/com.android.providers.telephony/databases/mmssms.db
adb shell ls -alZ /data/user_de/0/com.android.providers.telephony/databases/mmssms.db
```
The important thing was to additionally change the file SELinux security context with `chcon`.
And after rebooting the old SMS messages were finally recognized!
Upvotes: 2 <issue_comment>username_3: username_2's solution works for me.
I pulled the mmssms.db file from a previous NANDROID backup of my phone and was able to restore all the old SMS messages from it by doing those commands in an adb shell.
It didn't work until I used:
`adb shell chcon u:object_r:radio_data_file:s0 /data/user_de/0/com.android.providers.telephony/databases/mmssms.db`

2016/04/05 | 802 | 3,187 | <issue_start>username_0: I'm using Nexus 5 and 6P, Android 6 having a feature called "Battery optimization mode" or Doze mode (in short). It is allowing apps not to run, if they aren't used to avoid battery consumption.
Google play services consumes more battery, RAM and CPU. But it is not included in Doze mode.
I've sent multiple feedback from my devices about this issue, but Google is not hearing at all.
Anyone please help me clarify, Why Google play services not included in Doze mode?<issue_comment>username_1: This is one reason, there may be more
[Google Play Services](https://en.m.wikipedia.org/wiki/Google_Play_Services) has location API. And your Android Device Manager (ADM) which you use to track your stolen or misplaced device uses location API. Let's say you forgot your phone leaving for home and on reaching home want to locate your phone by logging into ADM
You can do that successfully only if your ADM (using location API) is not affected by *doze*, which is the case as cited here [Does Doze interfere with Android Device Manager?](http://m.androidcentral.com/forums-does-doze-interfere-android-device-manager). If *doze* affected Play Services, then you won't be able to track your phone at all
Upvotes: 2 <issue_comment>username_2: Google Play services is excluded because Google wants it so. It has to remained excluded from Doze or any power saving mode because apps depending upon [Google Cloud Messaging](https://developers.google.com/cloud-messaging/gcm#arch) (GCM) may fail to serve the user appropriately, hence, ruining the user's experience with Android big time. A [GCM Android Client](https://developers.google.com/cloud-messaging/android/client) requires Play Store and Play services installed in Android device.
Anyhow, here's the brief reason: in the file `/system/etc/sysconfig/google.xml`, other than the usage policy of the file it is noted:
```
<*allow-in-power-save package="com.google.android.gms"* />
<*allow-in-power-save-except-idle package="com.android.vending"* />
```
where,
* *com.google.android.gms* : package name of Google Play services
* *com.android.vending*: package name of Google Play Store
I cannot precisely speak of what counts as *other things*. My educated guess is the APIs made available through Play Services. Refer to *Table 1.* [here](https://developers.google.com/android/guides/setup#add_google_play_services_to_your_project) to see the list of those APIs.
**Note**: it is beyond the scope of this answer or the question itself why Google decided to keep Play Services and Store always excluded from power saving features of Android instead of finding and implementing a hybrid path.
Upvotes: 3 [selected_answer]<issue_comment>username_3: Google Play Services is in charge of Google Cloud Messaging (GCM). [GCM is the mechanism by which applications can request to exit doze mode](https://developer.android.com/training/monitoring-device-state/doze-standby.html#using_gcm), upon receiving [*high priority* messages](https://developers.google.com/cloud-messaging/concept-options) from GCM. In other words, Google Play Services is partly in control of doze mode, so it cannot be dozed.

* The media files are synced using rsync.
* The system apps are updated anyway when flashing new ROM.

2016/04/06 | 769 | 3,245 | <issue_start>username_0: I have a Samsung Galaxy S4 (Lollipop) and a Visual Elite Prestige 10Q tablet (Kit-Kat rooted with KingRoot), and I'd like to be able to use Bluetooth tethering to let the tablet share the phone's data connection. Wifi tethering works fine, but it creates a heavy draw on the phone's battery to run both the cellular and wifi radio systems; as I understand it, Bluetooth uses much less battery than wifi (less power required to transmit, hence the shorter range).
Unfortunately, even though I went through the process in [this answer](https://android.stackexchange.com/questions/49852/android-to-android-bluetooth-tether) the tablet was unable to see the internet connection via the phone. The two devices are paired, and I've used the phone's Bluetooth for months to play music in my car. How can I trouble shoot this and get the connection working?<issue_comment>username_1: As you mentioned you want to share Internet from Mobile to your tablet using your phone's Bluetooth tethering.
**So first lets understand a little bit about Bluetooth services**: A device which need to access internet via Bluetooth from other device should have **Bluetooth PAN** Service (BT Personal Area Networking) installed/enabled. While the device offering the internet should have the **Bluetooth DUN** Service (BT Dial-up-networking Service) installed/enabled.
**How Connection is established:**
Device with (with BT PAN) establish a wireless dialup connection by dialing a certain code (#99 for GSM devices & #777 for CDMA devices) required to make use of the modem of the internet providing device (equipped with BT DUN). If all goes well connection is established.
**Your Case**:
Since most of the mobile phones and tablets are only equipped with BT-DUN Service and not with BT-PAN Service.. Your tablet is not able to establish the internet connection using your phone's mobile data service. But they can however do other BT exchanges using BT FTP (file Transfer) BT Audio (for headphone/voice) etc.
Since most of the PC's and Laptop does have this BT PAN service enabled, they are able to use the BT tethering from devices offering it.
**Solution for You:**
The most hassle free and easiest solution for you is to use Mobile Phone's WiFi Hotspot for sharing internet to your tablet. this should work well, provided u arent using a illegally unlocked phone (as hotspot functionality gets disabled in some unlock cases like this)
Hope that answer your query. If you still require any help feel free to let us know, we are always here to help :)

Since the live boot vesa start mode works, the urandom error is not the problem.
Rather, the required video acceleration seems to be missing from vmware.
As a result you need to configure grub to start androïd in vesa mode.
This can be accomplished following a procedure described [here](https://www.nakivo.com/blog/installing-android-on-vmware-esxi-a-how-to-guide/) with some mistakes or incompletness or a little outdated.
After the standard install, you need to
* reboot,
* On grub boot choice (white text on black background), keep first choice and type 'e'
After that, you can see existing boot commands in the boot sequence.
- Select the upper item and
- press e once more
To edit the boot command for GRUB, Use arrows to reach the right position
* replace the word "quiet" by "nomodeset xforcevesa", you should have:
>
> kernel /android-?.?-r?/kernel nomodeset xforcevesa root=/dev/ram0
> androidboot.selinux=permissive SRC=/android-?.?-r?
>
>
>
presse **enter** to save. then **b** to boot.
For the grub configuration to persist upon restart,
edit its configuration file:
>
> mkdir /mnt/sda mount /dev/block/sda1 /mnt/sda vi
> /mnt/sda/grub/menu.lst
>
>
>
Press "i" to use insertion mode:
* replace the word "quiet" by "nomodeset xforcevesa",
escape to go back to command mode.
Then
ZZ or :wq!
to save and quit
You now can restart your vm using your custom configuration.
If ever you wait too long without any action,
your screen might turn black, entering the sleep mode.
Use your keynoard's menu key to recover a usable screen.

Apparently this was a problem with the S6, where the 'solution' was to use third-party Wi-Fi management apps that no longer work in Marshmallow.

But that no longer works, as per the error message above...<issue_comment>username_1: The method described in this answer does not require root, but it does require that you have a Wi-Fi access point ("router") you control.
---
One possible but very tedious and hacky solution is to host the SSIDs on a Wi-Fi access point you control, so that they are visible on the S7. Then you can "forget" them through the normal Wi-Fi settings page. The list of saved SSIDs can be retrieved (but not altered directly!) with third-party Wi-Fi management apps.
Having an access point capable of hosting "guest" networks/SSIDs is particularly helpful here. Otherwise, you'll need a wired connection so you don't kick yourself out by changing the SSID around.
Of course, this is quite a terrible solution in every way except that it works. So hopefully someone will have a better solution available.

```
network={
ssid="network_ssid"
psk="secretpassphrase"
key_mgmt=WPA-PSK
priority=1
}
```
Remove the blocks of the networks you want to get rid off, save the file, reboot – and they should be gone.
For app-based solutions, be welcome to check my list of apps for [Global WiFi Configuration](https://android.izzysoft.de/applists/category/named/network_wifi_config#group_421).

I have no settings area like before where I can adjust it. I can change the background but that's it. I can't adjust or change the bubble or its color? It's really hard on my eyes. Is there a way to chsnge them still or do I have to download a theme? Seems silly to chsnge the theme for a text bubble option!<issue_comment>username_1: I have an S5, S4, and Note 2, and I also got fed up with the Stock Messaging app.
I highly recommend using [**Textra SMS**](https://play.google.com/store/apps/details?id=com.textra&hl=en). It has about 250,000 good reviews, many of them from Samsung users.
It's not one of those apps that use data and give you a separate phone number, Textra is a replacement stock SMS app with major customization.

2016/04/08 | 748 | 3,071 | <issue_start>username_0: I've rooted my phone but now I'm scared that it would be bricked. I've seen a page on "Tips to prevent from bricking" and it said to install custom ROM recovery or something like that. I think there were two things; ClockWorkMod and Team Win.
I tried to install one and downloaded ROM manager but didn't work (didn't find my device model name).
Doing what kind of things increases the probability of bricking my device?<issue_comment>username_1: Doing exactly what you are doing is probably the biggest chance of bricking your phone - **experimenting without proper knowledge and understanding** of how things work. Go into xda-developers and find your phone's forum. Then start reading - how to install a ROM and a Recovery, change kernels etc. Read the threads and follow the steps exactly as they are shown and you won't be having any problems. All it takes is for you to mess up a single step, to brick your phone - may it be you download wrong file, not for your model or you type in wrong command etc. Still Android these days (not like back in 2010 for example) are quite resilient. It's not too difficult to recover from almost all kinds of bricks.
**TLDR Read how other people did it before you on accredited sites like XDA-Developers and be careful.**
Story time: I've been doing this (rooting, installing roms etc. - being power user) for 5-6 years now so I know my stuff. I started unlocking my LG G4, then rooting, then installing recovery. What I did here was really stupid. Instead of installing a recovery I booted into it - so I had access to it only once. But I didn't notice right away. I installed my files, and the installer required a restart, and to boot back into recovery. But since I didn't install recovery the first time, as soon as I restarted my phone I literally messed up. I went into semi-soft brick. No access to fastboot, couldn't hook up my phone to my PC to execute commands, and the phone was in bootloop, only going as far as the logo.
Well I panicked a bit, went into the forum and started reading for solutions. At the end, something written for totally different thing allowed me to push some commands, and salvage my phone.
Also on your comment: And in general, don't root if you don't know what it is. Many people do root exactly for your reasons "people say its cool" I rooted to install xposed and get some modules I need.
Upvotes: 1 <issue_comment>username_2: Things like :
* Flashing a recovery/ROM that is built for a different device other than yours
* Installing beta/unstable builds of ROMs/recoveries
* Messing about with system files without a proper backup
* Typing the wrong command while modifying your device
These increase the probability of your device getting bricked.
Always ensure that you have something to fall back onto in case of an error. A NANDroid backup is recommended.
In case you run into any problem, sites like [XDA-Developers](http://www.xda-developers.com/) are a good source of help.
Rooting isn't bad, as long as you know what you're doing.

2016/04/08 | 3,518 | 13,432 | <issue_start>username_0: I have previously nervously rooted phones I've owned (Samsung S2, S3) as I wanted to be able to use AdAway ad-blocker, effective not just in browsers (e.g. AdBlocker) but also in other apps. I say nervously because I always found the mode in which these modified ROMs are offered (websites such as XDA developers) a bit dodgy/flimsy. Nevertheless, this has worked well in the past, but I am aware that I might just have been lucky, as those forums abound with bad experiences, i.e. bricked phones, or at the very least tons of wasted time trying to at least make your phone work again even in its stock let alone rooted firmware.
Now I have a new phone, the most expensive I've owned so far (S7 Edge), and browsing these same websites again, I feel just as edgy performing this risky operation. For instance, the S7 Edge section of the XDA-devs [website](http://forum.xda-developers.com/s7-edge/development) has several rooted ROMs available, however without spending hours and hours it is not obvious what the differences between them are. To name, just a few doubts:
1) how are 'recovery' firmwares different from ones just called 'Kernel' or 'ROM'?
2) in what way does each of those ROMs differ from the CyanogenMod, which I've happily used in the past but for which there is no S7 Edge version released from what I can see? Incidentally, I used Odin to install CyanogenMod on my old phones, rather than a 'recovery'.
3) are there major differences in how the S7 Edge will operate with such a rooted firmware/ROM as compared to the stock one? Specifically, will it be any more vulnerable to exploits etc, given that no-one can really tell whether these ROMs have e.g. built-in trojans?
Given all these concerns about Android rooting, is there any way that adblocking can be performed without rooting? If not, what is the least-intrusive and least-risky way to root an Android (in this case an S7 Edge)?<issue_comment>username_1: Answering your first and main question: **Ad blocking without rooting**
On non-rooted devices running Android 4.1.2, 4.2.1 and higher, Adblock Plus will filter all WiFi traffic, but it needs to be configured as a proxy server manually. Detailed instructions are provided by Adblock Plus for not experienced users.

They refer to different things altogether.
**Recovery** :
Recovery refers to the dedicated, bootable partition that has the recovery console installed. A combination of key presses (usually power + volume up) or instructions from a command line, will boot your phone to recovery, where you can find tools to help repair (recover) your installation, install official OS updates and/or custom ROMs and other stuff.
Recovery firmwares contain a custom recovery file that enables you to do a lot more additional things than what the stock recovery offers. This can include options to re-root your device, a file browser to browse through your files, format individual partitions and more.
**Kernel** :
Kernel is the core of the operating system that handles requests to and from the hardware, memory and process management and all the low-level stuff that is necessary for Android to be able to run. It is based on the Linux kernel with a few modifications to suit it to Android versions.
Kernel firmwares contain a kernel that, when installed, replaces the existing kernel and modifies the low level stuff in order to tweak the software to make better use of the hardware. Better battery life, higher performance, increased signal reception, etc. are some things a custom kernel can do.
**ROM** :
A custom ROM replaces your device's Android operating system — normally stored in read-only memory — with a new or modified version of the Android operating system. A popular custom ROM is CyanogenMod, which gives you a host of new options as compared to the original firmware.
ROMs may contain a different Android system altogether or might also include a kernel and/or a recovery. It's best to read the OP on those threads to find out what it contains.

This is subjective to the ROM you are referring to. Some ROMs use the RRO-Layers engine for theming, while others use the CyanogenMod theme engine. Some ROMs might have additional features over those present in CyanogenMod, others might have a different user interface altogether.
As to the unavailability of an S7 Edge version of CyanogenMod, this is because official builds aren't made yet or are in the works.

Again, these are subjective to the ROM you choose. Basically, some offer better performance, others offer better battery life, and a few more offer a mix of the two. It depends on which ROM you choose.
There are a few ROMs that might be more vulnerable to exploits than others. Therefore, it is recommended to go for an official build of a popular custom ROM, as they are tested and checked so that they would not contain malware.

Rooting is device-specific. There are different ways to achieve root access on different devices. In the case of an S7 Edge, you could try [Kingo Root](https://www.kingoapp.com/), it has been claimed to work on an S7 Edge. However, be careful, one wrong step can brick your device.

It includes ad blocking functionality as well as removing their containers on webpages. For it you will have to install one of the following apps from Play Store
1. [Adblock fast](https://play.google.com/store/apps/details?id=com.rocketshipapps.adblockfast)
2. [Crystal](https://play.google.com/store/apps/details?id=co.crystalapp.crystal)
3. [Adblock Plus for Samsung](https://play.google.com/store/apps/details?id=org.adblockplus.adblockplussbrowser)
After installing open
Internet->More->Settings->Advanced->Block Content (enable the switch and choose the adblocker that you installed out of the above).
Unfortunately this is only an app based solution not system wide (which would only be available by rooting).
As far as rooting is concerned-
* don't try to do it.You will lose Samsung Pay, Private Mode, Warranty and obviously Knox will be tripped. (if you don't mind losing these features go ahead!)
**Ans 2**- On S7 you will not be able to use Cyanogenmod for many months or never (as Samsung has blocked bootloaders on Qualcomm versions and they don't give Exynos source code). Hence all ROMs on XDA are stock modified ROMs (only containing small changes like adblocker, some x kernel, some changes here n there but mostly stock)
If CM comes to S7 then you will have to install via 'recovery'.
**Ans 3** As these ROMs will be mostly equivalent to stock, they will operate normally (except until **You** modify it heavily). These ROMs won't come with Trojans for sure
**No, system wide adblocking can't be performed without root.**
**Least risky way to root will be flashing Chainfire's autoroot via odin (only Exynos)**
Upvotes: 2 <issue_comment>username_4: I have no idea why anybody has not mentioned "*Lucky Patcher*" yet...
*Lucky Patcher* is an application that can **modify applications/APK** files present on the phone by patching them.
One of the things it can do, for example, is remove ads. It's ad removing mechanism is very powerful and can not only make ads not load, but also **remove/shrink the ad boxes so you wouldn't even think they were there**.
It needs root if you want to patch applications without reinstalling them but it can also patch applications **without root** by uninstalling them, patching them and then installing them again.
It can do many other things too (some which are illicit and I highly discourage you from doing them)...
The application's interface can be overwhelming and takes some getting use to but once you get the hang of it, you will find it's power beats almost every other adblocker for Android out there.
**How to patch an application to remove ads:**
1. Open *Lucky Patcher* and tap on the application you wish to block the ads in.
2. Tap on "*Open Menu of Patches*"
3. Tap on "*Create Modified APK File*"
4. Tap on "*APK without Google Ads*"
5. Customize the ad-removal settings (if you want)
6. Tap on "*Rebuild The App*"
7. Wait until the patching process is complete and tap: "*Go to file*"
8. Tap on the first item that is in the list that appears
9. Tap "Uninstall and install" and follow Android's uninstall and install dialogs
10. Open the app and confirm that the ads have been removed!
Lucky Patcher can be downloaded [here](https://www.luckypatchers.com/download/).

If you have an unlocked bootloader you can then boot a custom recovery ([even without flashing it](https://aubykhan.wordpress.com/2013/07/21/android-tip-boot-into-twrp-or-cwm-recovery-without-flashing/)) and then install [MoaAB](http://forum.xda-developers.com/showthread.php?t=1916098).
I use the same approach on three different devices with effective ad blocking. Not sure of the specifics for Samsung S7 Edge though.
Upvotes: 1 <issue_comment>username_6: In principle you can root the device yourself and use iptables-based transparent proxying to forward DNS and http queries to proxies that are not running with root privileges. Then you don't have to trust anyone else's software to be installed as root. In practice I don't know if there's any good software setup to run this way on Android.
For what it's worth, DNS blackholing is one of the most effective ways to adblock in apps, and it's easy to do yourself.
Upvotes: 1 <issue_comment>username_7: I'm not sure what you find dodgy about XDA, but it's not really any different from what manufacturers do when loading/updating phones. An official update could just as easily contain a backdoor, virus, etc and you would install it without a second thought. As long as it's done properly, phones being bricked as a result is not common at all, and is easily fixable if it does occur.
Rooting is extremely low-risk, but is currently not available for the S7 as they are still working on it. Things like that are also tested within the developer community before being released to the public.
As far as rooting, you MUST have the exynos version of the S7 for it to work. The Snapdragon version does not currently have a working root unless you install a custom rom.
<http://forum.xda-developers.com/s7-edge/development/sm-g935-exynos-cf-auto-root-t3337354>
If you prefer not to root, I found 2 options on a list of non-root apps for system wide ad blocking that does not require it. I can't post more than 2 links because my account is new, so I'll just link the thread I got them from.

2016/04/08 | 2,466 | 6,938 | <issue_start>username_0: I have been attempting to get reverse tethering working on my phone. I have a Galaxy S5 (g900t), running cyanogenmod 13 (marshmallow)...rooted, and with busybox.
\*Edit: I've made some progress. I ran this on my ubuntu machine:
```
sudo ip addr flush dev eth0
sudo ip addr flush dev usb0
sudo brctl addbr br0
sudo brctl addif br0 eth0 usb0
sudo ip link set dev br0 up
sudo dhclient br0
```
And then I ran this in the adb shell:
```
dhcptool rndis0
```
### After doing this, I seem to have internet.
I can do `wget -s google.com`. However, it only works as `su`.
```
root@klte:/ # wget -s google.com
Connecting to google.com (172.16.31.10:80)
Connecting to www.google.com (172.16.31.10:80)
2000@klte:/ $ wget -s google.com
wget: bad address 'google.com'
```
I verified that I can do `wget` as a regular user when I am connected through cell network or wifi.
### So my question is:
Why would I be able to apparently access the internet as `su`, but not as a regular user? I've checked my `ifconfig` and `route` settings, and they all look the same either as `su` or regular user. Does anyone see what I'm doing wrong?
---
### Config setting printouts
These settings are all the same, whether I run them as `su` or not.
Here is my `ifconfig`:
```
1|root@klte:/ # ifconfig rndis0
rndis0 Link encap:Ethernet HWaddr 62:91:0C:85:FD:6B

And here is my `route` table:
```

192.168.22.0 * 255.255.255.0 U 0 0 0 rndis0
```
And it appears that my DNS servers are set correctly:
```
root@klte:/ # cat /etc/resolv.conf
nameserver 8.8.4.4
nameserver 8.8.8.8
```<issue_comment>username_1: I know I'm answering an old question here, but I've run into the same problem with Android Nougat (LineageOS 14.1), and I might as well post the solution I found:
Run the following as `root` on the phone (through `adb`) after starting tethering:
```
dhcptool rndis0
ip rule add from all lookup main pref 99
```
(the commands to run on the computer aren't in question here; in my case, I had to `modprobe usbnet` and `modprobe rndis-host` to even see the `usb0` interface, but that's a completely different problem).
The thing is, Android uses a fairly complex routing setup, with different routing tables (see below for a dump). The `dhcptool rndis0` command puts the appropriate routing lines in the standard `main` routing table, but the `main` table is only consulted under a rule that says `uidrange 0-0` (that is, for `root`). What the second line above does is force the use of the `main` routing table for everything. This should be undone aftewards with
```
ip rule del pref 99
```
This seems to work for me, but I'm not sure how robust it is. Maybe it subtly breaks something that I didn't realize it would. Maybe there's a higher-level Android-specific command that's better and that I don't know about.
As a reminder, one can use `ip rule show` to display the current routing rules, and `ip route show table wlan0` to show the content of table `wlan0` (say).
For reference, here are the routing rules I found on my Android once tethering was set up:
```
0: from all lookup local
10000: from all fwmark 0xc0000/0xd0000 lookup legacy_system
10500: from all oif wlan0 uidrange 0-0 lookup wlan0
10500: from all oif rndis0 uidrange 0-0 lookup local_network
13000: from all fwmark 0x10063/0x1ffff lookup local_network
13000: from all fwmark 0x10064/0x1ffff lookup wlan0
14000: from all oif wlan0 lookup wlan0
14000: from all oif rndis0 lookup local_network
15000: from all fwmark 0x0/0x10000 lookup legacy_system
16000: from all fwmark 0x0/0x10000 lookup legacy_network
17000: from all fwmark 0x0/0x10000 lookup local_network
18000: from all iif rndis0 lookup wlan0
19000: from all fwmark 0x64/0x1ffff lookup wlan0
22000: from all fwmark 0x0/0xffff lookup wlan0
23000: from all fwmark 0x0/0xffff uidrange 0-0 lookup main
32000: from all unreachable
```

USB reverse tethering is only working for user 'root'.
For the user 'shell' it does not work.
1. USB cable is plugin to PC with Window 7
2. Enabled 'USB tethering' on the phone
3. Window automatically installed 'Remote Ndis Driver'
4. Manually enable 'Internet Connection sharing' on my LAN Ndis(I get the internet from) for the 'USB Remote Ndis'. Doing so Windows assigns 'USB Remote Ndis' the IP 192.168.137.1
^ by this setup on the PC is complete
Now I use "adb.exe shell" to login to android
-> su
-> ifconfig rndis0 192.168.137.2 netmask 255.255.255.0
-> route add default gw 192.168.137.1 dev rndis0

inet addr:192.168.42.129 Bcast:192.168.42.255 Mask:255.255.255.0
now the only line that's left to enable USB reverse tethering for at least root is:
```
route add default gw 192.168.42.1 dev rndis0
```
Now I'm just experimenting with
ip route
ip route help

It sets up a VPN on the android which redirects all traffic across an `adb reverse` port connection. Doesn't even require root at all.

When I try to search for it in the Settings app, it does show up:

*[click for larger image](https://i.stack.imgur.com/zzgExl.png)*
Unfortunately, tapping on it simply brings me right back to Developer settings where that option is not found.
The alternative instruction is to reboot to bootloader and issue the `fastboot --wipe-and-use-fbe` command, but it fails with "**fastboot: unknown option -- wipe-and-use-fbe**" error. I am running the SDK Tools version 25.1.1 rc1, and Platform-tools version 24 rc1 from the preview channel of Android SDK, with latest fastboot utility (version 102d0d1e73de-android).
I performed a complete wipe (system and userdata), and flashed all the [NPC56P](https://developer.android.com/preview/download.html#flash) images manually (bootloader, radio, recovery, system, cache, userdata.) The phone is encrypted, Screen lock is set to "PIN", and Secure start-up (requiring PIN before boot) is enabled.
Is this feature simply not available in Preview 1 and/or Nexus 6? How can I enable it?<issue_comment>username_1: I'm afraid that in Preview 1 this is only available on the Nexus 5X and the Nexus 6P. In Preview 2, support for the Pixel C is added. No other devices are supported at the moment. Sorry!

You can check various option available with your fastboot.
fastboot --help.
--wipe-and-use-fbe On devices which support it,
erase userdata and cache, and
enable file-based encryption
But it does not enable file encryption for me after executing the above command.

Is there any way to set which **incoming** connections and on which ports should be allowed/denied (something like Inbound Rules in Windows Firewall)? I'm OK with with the app requiring root.<issue_comment>username_1: I'm afraid that in Preview 1 this is only available on the Nexus 5X and the Nexus 6P.

2016/04/09 | 254 | 1,002 | <issue_start>username_0: After upgrading to Android 6.0.1 (Marshmallow), I can't send or receive SMS texts.
I'm on a Galaxy S6 on Verizon. I tried rebooting in Safe Mode, disabling Google Hangouts, uninstalling Mighty Text, with no change in status. I used Samsung Messages, Google Messenger, all with no results. I don't have permission to edit my Access Point Names.
Help?<issue_comment>username_1: I had the same problem. I fixed it by doing this:
Go to Settings -> Privacy and Safety -> App permissions -> SMS
Turn off the Messages app and turn it back on.
