2015/12/10 | 461 | 1,967 | <issue_start>username_0: After upgrading to my Nexus 5 to Marshmallow, I find myself experiencing crashes regularly. The phone screen will go black, and attempts to restart will make it to the home screen for a few seconds before the screen goes black again (regardless of power levels). The only way to restore normal functionality is to hook the phone up to a charger, at which point it will boot without issue.
I have tried clearing up disk space, which did not seem to help. I have tried doing a factory reset (the one via "Settings > Backup & reset > Factory data reset"), but that also does not seem to have stabilized the environment any more. It doesn't happen at regular intervals, nor does it always happen with the same app. I have noticed that it *often* happens while I am using SuperCell apps (CoC or Boom Beach), but that my be correlation rather than causation. It has **never** happened while my phone is plugged in.
All this said, anyone have ideas on what may be causing it or diagnostic steps to take? I tried looking for logs, but haven't found much. Could also be a hardware issue and the update is a red herring, but thought I would ask those with more knowledge before writing my phone off as lost.<issue_comment>username_1: To disable automatically disconnecting from a "poor" WiFi network, you will want to toggle the **Avoid poor Wi-Fi connections** setting.
This can usually be found in **Settings > Wi-Fi > [menu] > Advanced > Avoid poor Wi-Fi connections**.

2015/12/10 | 1,920 | 6,505 | <issue_start>username_0: I did two things to install Xposed. Firstly, I flashed `xposed-v75-sdk21-x86.zip` and then installed the .apk file. I can now uninstall the app itself but how can I erase the flashed file of the .zip?
Also, where are the modules stored? How to delete the modules completely?
Device is LG G3 D855. Running on Cloudy G3 ROM.<issue_comment>username_1: Until KitKat, to disable the framework you need to flash this zip (stored on your `/sd` at installation **Xposed-Disabler-Recovery.zip** .
As far as uninstalling the modules goes, selecting *Modules*, (from installer), long pressing the module(s) to be removed does it in KitKat. Of course, changes take place after reboot, and I am assuming the same holds for higher versions of Android. Modules reside as per [Izzy's comment](https://android.stackexchange.com/questions/131236/how-to-completely-delete-xposed-framework-and-modules/131294#comment163939_131236) for KitKat.
Quoting extracts from [How to Uninstall Xposed Framework on Android Lollipop Guides Aug 21, 2015](http://www.droidviews.com/how-to-uninstall-xposed-framework-on-android-lollipop/):
>
> Xposed Framework on Lollipop needs to be installed manually through a Custom Recovery unlike in Jelly Bean and Kitkat where the Xposed installer apk file would install the framework on your system automatically. So uninstalling Xposed Framework on Lollipop would require you to flash an **Xposed Uninstaller Script using a Custom Recovery like TWRP or CWM.**... Take note that **Xposed Uninstaller are different for different devices like arm, arm64, x86.** Find the Uninstaller Script for your device in the Downloads section. Also, Uninstaller Scripts are different for Android versions 5.0 (SDK 21) and 5.1 (SDK 22).

It further provides uninstall instructions and scripts.
I am on KitKat and have no way of testing this. It was a coincidence reading this and later seeing your question.

For any Android Lollipop

See the attached files in the first post of [this thread](http://forum.xda-developers.com/showthread.php?t=3034811). In relevance to your device's CPU architecture, download the uninstaller archive and flash it from the custom recovery. It would undo the changes the installer archive made.
In essence, the installer archive keeps the original system files but appends in their name `.orig` or convert them into archives (unofficial installers do). It then places its modified files at their location. All uninstaller does is remove the modified and extra files and change the backed up files back to their original self.
Relevant section from the uninstaller script
```

```
If you've the knowledge of setting the appropriate SELinux context for a file in Android from recovery mode, you can simply map the files the installer would've changed, revert the changes using command-line and set the correct context. No uninstaller would be required.
**Note:** If you're not using the official Xposed Framework then the uninstaller may not work for you. It may even cause unforeseen issues. Best is to search the web for the uninstaller.
>
> Also, where are the modules stored?

>
>
* Xposed Installer app downloads the modules under `/sdcard/Download`.
* They may be called modules [but they simply are apps to Android](https://github.com/rovo89/XposedBridge/wiki/Development-tutorial#creating-the-project), hence the APK would be found under `/data/app` or the locations covered [here](https://android.stackexchange.com/a/28231/96277) by Izzy. Alike every app, there data directory would be found under `/data/data`.

Deleting an Xposed module is no different than removing any user installed app from Android. So, you can use any technique that you would use to remove an ordinary app.
Note that the file `XposedBridge.jar` under `/system/framework/` is what provides modules the necessary APIs to interact with the modified framework.
---
For Android 4.2.x - 4.4.x
=========================
Use the file [`Xposed-Disabler-Recovery.zip`](http://forum.xda-developers.com/showpost.php?p=52632524&postcount=5) located at `/sdcard/Android/data/de.robv.android.xposed.installer/files`. Flash that file from recovery mode (requires a custom recovery) to disable Xposed Framework. If you don't have such file, download it from the first post of the [official thread](http://forum.xda-developers.com/xposed/xposed-installer-versions-changelog-t2714053).
That archive, in essence, changes `/system/bin/app_process.orig` to `/system/bin/app_process` i.e. it removes the modified `app_process` and brings the original file back to its glory. It doesn't delete the Installer app. You can make those changes on your own too using adb in recovery mode.
The concept of modules here is no different from what is covered in the above section.

2015/12/11 | 741 | 2,845 | <issue_start>username_0: I got an old phone: an HTC WildFire S. Everything works fine, except that the power button has gone bad. Can I start the phone from my computer over a USB connection somehow?<issue_comment>username_1: When your phone is not turned on it can't have a adb service running (Disregarding the possible technical difficulties it would also be a security issue.)
Try the following instead:
1. Take out your battery and connect the phone to a charger
2. Your phone should now turn on.
3. Insert your battery.
4. Hold power button (+).
Your device should boot now. I'm not sure if this will work for you but i booted my old ZTE Blade using these steps.

============
Many PCs can be woken from sleep mode via a keypress. Some, if configured to allow "wake on LAN", can even be woken via a specially-composed Ethernet packet.
I'm unaware of any way to force an Android device to power on using a special USB command.
What to try
===========
* You can try removing and reinstalling the battery.
* Or you can try connecting the phone to a charger; there might be a slim chance that this will force it to power on.
* If that doesn't work, you can try a Google search for [ [how to power up Android phone without power button](https://www.addictivetips.com/android/turn-on-an-android-phone-with-a-broken-power-button/) ]. You'll find lots of results, including [an article on the AddictiveTips website](https://www.addictivetips.com/android/turn-on-an-android-phone-with-a-broken-power-button/) and many others. These articles have additional suggestions which I haven't mentioned. Maybe one of the articles has a tip which can help you.
What next
=========
If none of the aforementioned ideas help, you can then either:
* Attempt to repair the phone yourself.
* Pay a technician to repair it.
* Or try to sell it (at a discount) to a local shop, which can then try to fix it.

* install fastboot
* install VCOM preloader drivers
* open scatter file with SP Flash Tool
* add new entry for EMMC\_USER (with start address and size of boot partition) at Read back option
* click readback (start)
* connect phone (readback will start as soon as preloader is detected)
* insert battery
* hold Volume button (down = fastboot, up = recovery)
* disconnect phone (after readback finished)
* connect phone (phone reboots)
* still hold Volume button until phone booted into fastboot or recovery
* boot into bootloader (from recovery)
* while in fastboot mode type in cmd.exe
fastboot oem off-mode-charge 0
this works similar for flashing stock rom (tools without readback option). for samsung devices (no fastboot) a JIG dongle may help

2015/12/11 | 918 | 3,586 | <issue_start>username_0: I have a Galaxy SIII (Android 4.3) phone on the Vodafone network (UK). I was using WiFi when available and mobile data occasionally. It all worked fine. When on mobile data, I would see an icon on the top bar showing a little letter H with two arrows underneath.
But now the mobile data has sort-of stopped working. I say sort of because it appears that I can still turn mobile data on, and I still get the little H with two arrows, but none of my apps that use data appear to actually be able to communicate with the internet. I don't actually get any "no connection" messages, instead, I just get rotating wheels and other indicators that they're trying to get something that's not arriving.
If I switch back to wifi then everything starts working again.
Any ideas?
**EDIT:** I have not installed any custom ROM. The phone is not rooted.
**EDIT:** I just called vodafone, who suggested a variety of things that made no difference. Now they've said it may be a fault in my SIM card and are sending me a new one.
**EDIT:** New sim card arrived. No difference. More calls to vodafone, multiple suggestions... nothing has worked.
**EDIT:** Tried sim in Galaxy SII... all symptoms identical. Saw little H icon (sometimes flipping to "H+" or "3G"), but no mobile data getting through.
**SOLVED!** it suddenly started working again. I suspect it was a fault at vodafone's end and my last call to tech support induced someone there to correct the fault.<issue_comment>username_1: **TLDR: use a SIM with a different number (no matter if Vodafone or a different service).**
We see a symptom (no net), but we have to find out the cause first, to solve the problem. So let's think step by step, what the problem could be.
* **Faulty phone?**
* No, your other phone (the SII) doesn't work either (using the same SIM).\*
* **Faulty SIM?**
* No, you have already tried a new SIM.
* **Faulty cellular tower?**
* No, you have already tried an other tower (by changing location).
* **Faulty Vodafone?**
* Likely, because I'm sure they have net, and you're sure that they have to give you net (data limit hadn't been reached), plus we've found out in the previous questions that it isn't about the net is stuck between you and them. The only problem here is that you have already asked them, so they should have investigated the issue. But I'm sure they will take a next - more in-depth - look, since all the other possibilites are crossed out now.
I advise you to call Vodafone again, tell them that your phone is ok, your SIM is ok, the local tower is ok, your data subscription is ok, and then there is nothing left to do: they have to accept the fact that there is something wrong with their service. Until that, use a SIM with a different number, I'm sure it'll work in your current phone.
\* To be 100% that your phone is ok, try a different SIM with a **different number**. I think the new number can still be Vodafone, because only your current account is affected (your current number), not the whole infrastructure. However, if you don't want to experiment (and your phone is unlocked), you can immediately get a SIM from an other company, as Firelord suggested in a comment below. (So that you are safe, even if the whole Vodafone system is damaged.)

I have not used an Android device however so I do not really understand how it works and compares. My general understanding is that it is similar to Gnome-like Linux interfaces, but I guess there must be some differences since Android has a layer of Java, [the Dalvik/ART virtual machine](https://en.wikipedia.org/wiki/Android_Runtime), between the Linux kernel and the UI elements.
I have read the Android [developer overview to the UI](http://developer.android.com/guide/topics/ui/overview.html) but that has not really helped me understand how the UI operates from a workflow basis.
Obviously I could just buy an Android tablet and use it for a few months, but I am hoping there is some way for me to understand the Android UI and how it differs from other major UIs. How can I get this knowledge?<issue_comment>username_1: Only by using Android device.
If you don't want to buy a tablet or phone, just install Android emulator like Genymotion, Bluestacks or a classic emulator from Android SDK, but none of these would give you the great experience as using and playing with real device.

**Android** is primarily designed for a single user, so there's no concept of CLI login. In fact virtual terminals/consoles are disabled in kernel by default. `init` - after starting all native services including Surface Flinger (Android's Display Server) - starts a service named `zygote` which is a special process to fork Java-like Virtual Machines. Android's core framework (`system_server`) and all apps run in separate instances of VMs. `system_server` starts apps which are configured to run on boot, including many system apps.
So what we see after the boot animation ends is **System UI** app. This app is responsible for showing lock screen, status bar, notifications etc. `system_server` has 100+ Java services running inside it including Activity Manager, Permissions Manager and Window Manager. WM communicates with Surface Flinger to draw surfaces on screen as requested by `system_server` and apps. Another core component we see is a **Home** or **Launcher** app which is somewhat like a Desktop. It shows, at least, icons of all installed apps and forwards the request to `system_server` for launching/showing the app when we tap an app icon. So everything we see on an Android device is an app.

2015/12/12 | 616 | 2,263 | <issue_start>username_0: After doing something wrong while installing CyanogenMod 13, I flashed a google marshmallow stock rom. I wanted to go back to CyanogenMod 12, so I backed up my data using CWM recovery, factory reset, and installed CM12. After making sure it was working, I flashed Gapps and restored from my recovery. My apps were back, but I was also back with the google stock rom. Is there any way to only back up the app data?<issue_comment>username_1: You can use Titanium Backup Pro to backup the apk file as well as data of your apps.Otherwise, if you want to backup just the apk files, you can use App Backup Restore.You can also copy the apk files from \data\app to your SD card via a suitable file explorer like Root Explorer or ES File Explorer.
Upvotes: 0 <issue_comment>username_2: As mentioned in the comments by Firelord and me, there are multiple approaches:
* you could use [Titanium Backup](https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup)
* you could use [ES File Manager](https://play.google.com/store/apps/details?id=com.estrongs.android.pop), which includes an app manager capable of backing up apps and their data
* you could use [ADB backup](https://android.stackexchange.com/q/28296/16575)
* You could use [Adebar](https://github.com/username_2Soft/Adebar) to make the previous step easier
*TiBu* and *ES File Manager* require root to work. ADB and *Adebar* don't.
*Adebar* a.o. creates a script to backup each of your (user) apps into a separate archive using `adb backup` (and another one for the data of system apps, and two others for restore). While you could do a similar thing with TiBu (which uses its own backup format), *Adebar* runs from the command line while with TiBu you must use a GUI. Side effect from using *Adebar:* you'll have your device documented: tech specs, apps installed, etc :)
*Adebar* is pretty easy to install, but will require [adb](/questions/tagged/adb "show questions tagged 'adb'") to be available on your computer (see our [adb tag-wiki](https://android.stackexchange.com/tags/adb/info) for details on that). It runs fine on Linux, and recently was reported to run on Windows as well via Cygwin.

2015/12/12 | 724 | 2,476 | <issue_start>username_0: I used [Texdroider DPI](https://play.google.com/store/apps/details?id=com.texdroider.texdroider_dpi) to change the dpi from `320` to `300` and after the reboot it gets stuck at the lenovo logo. I could just flash it again but i don't have the rom on this pc, and it will take 10h to download it.
Is there any faster way to reset the dpi? I have TWRP installed. With android 5.0.1.
Edit:
Output of `cat /system/build.prop | grep density` is `ro.sf.lcd_density=300`
Tried editing [build.prop](http://pastebin.com/uWhckDpY) back to 320 with Sublime Text. Now the command returns `ro.sf.lcd_density=320` but it still gets stuck.<issue_comment>username_1: You can use Titanium Backup Pro to backup the apk file as well as data of your apps.Otherwise, if you want to backup just the apk files, you can use App Backup Restore.You can also copy the apk files from \data\app to your SD card via a suitable file explorer like Root Explorer or ES File Explorer.

* you could use [Titanium Backup](https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup)
* you could use [ES File Manager](https://play.google.com/store/apps/details?id=com.estrongs.android.pop), which includes an app manager capable of backing up apps and their data
* you could use [ADB backup](https://android.stackexchange.com/q/28296/16575)
* You could use [Adebar](https://github.com/username_2Soft/Adebar) to make the previous step easier
*TiBu* and *ES File Manager* require root to work. ADB and *Adebar* don't.
*Adebar* a.o. creates a script to backup each of your (user) apps into a separate archive using `adb backup` (and another one for the data of system apps, and two others for restore). While you could do a similar thing with TiBu (which uses its own backup format), *Adebar* runs from the command line while with TiBu you must use a GUI. Side effect from using *Adebar:* you'll have your device documented: tech specs, apps installed, etc :)
*Adebar* is pretty easy to install, but will require [adb](/questions/tagged/adb "show questions tagged 'adb'") to be available on your computer (see our [adb tag-wiki](https://android.stackexchange.com/tags/adb/info) for details on that). It runs fine on Linux, and recently was reported to run on Windows as well via Cygwin.

2015/12/12 | 304 | 1,405 | <issue_start>username_0: Today I discovered one incredibly useful app that allows you to remote control your computer using your mobile phone. However, you need to be connected to the internet on both the phone and the computer and the problem is I only have a limited amount of data to use every month on my phone which would probably last me about a week if I were to use this app everyday. Is it possible to remote control a computer from far away without being connected to the Internet on the mobile phone? I really hope it is.<issue_comment>username_1: **No, there isn't.**
The internet is what allows computers to connect to each other when they are not on the same network. This would technically be possible if both devices were connected to the same network (most commonly the same router or ethernet hookup), but when your device is connected to a cellular connection, the internet it is the only way to connect your computer and phone.
Upvotes: 1 <issue_comment>username_2: **No.** The reason you need your *limited data* is because that is how the data gets transferred from one device to another. Through internet. In order to send commands (which are basically data packages) to a device, you have to have a connection with that device. That connection is internet. There are other forms of data transfer methods of course (i.e. radiowaves) however that is no use in this case.

2015/12/13 | 772 | 3,016 | <issue_start>username_0: I would like to know if Android devices make active or passive scan when looking for the AP to connect. I've already made a test using Wireshark and wifi sniffer and it seems that while an iPhone sends Probe Request frames to discover available APs (active scan), my Android device sometimes sends Probe Request frame, but most of the times it does not send Probe Request frames at all, but waits for the AP to send a Beacon frame (passive scan).
I've been looking for some official info/documentation concerning this topic, but haven't found anything useful yet. I would be very grateful if someone could provide me with the answer to this question.<issue_comment>username_1: The only "official" explanation I found is in [this comment](https://android.googlesource.com/platform/frameworks/base/+/a5ec95cdb1a7d2024249277dff1f99d0046c9b56) (dated July 2009) in the Git repositories on android:
>
> wifi: **WifiManager.startScan() will now do passive scans by default**.
>
>
> Active scans will only happen if an hidden AP is in use, or if the new method
> *WifiManager.startScanActive()* is called.
>
>
>
The existence of an hidden function to start an active scan (reported [here](https://github.com/mozilla/MozStumbler/issues/40)) suggests that the normal scanning function is indeed passive. This is to be taken with a grain of salt, though, as the Android documentation doesn't explicitly tell if the function *WifiManager.startScan()* is passive or not.
Also related: this two posts on SO ([post 1](https://stackoverflow.com/questions/3439811/do-android-devices-scan-actively-for-wifi-networks?rq=1), [post 2](https://stackoverflow.com/questions/24670963/how-to-active-scan-wifi-in-android)) report that the scanning activity is passive (post 1) and that since android 4.3 it not even possible to call the active scan method (post 2) - but there is no link to official sources.
Upvotes: 4 [selected_answer]<issue_comment>username_2: I have been searching for the official document for an exact answer too. But I couldn't find any. Hence I'm writing this base my own assumption.
I believe a client device(mobile in this case) does both the active and passive scan.
My reasons are as below:
1. When a mobile activates the WiFi interface, it needs to scan for the beacons by nearby AP so that the available SSIDs will be listed for connection. This is a passive scanning mode.
2. A mobile which has been connected to several SSIDs before will bust the probe request frames(with all the SSIDs) to nearby AP and if the SSID match, the AP will respond to the probe request and the connection/authentication process will begin. This is an active scanning mode.
3. Special case for the AP with hidden SSID. When the user manually connecting to the hidden SSID, the mobile device will generate a probe request and broadcast it to the nearby AP. When the SSID matched any of the AP, it will follow by connection/authentication process. This is an active scanning mode too.

However, I am concerned if I will be able to control permissions on the "stock apps" without rooting or flashing my device with a new ROM? Even a Nexus will come with stuff like Google Maps, I am sure. So will I be able to control what Google Maps has access to, for example? What about Samsung devices and the egregious bloatmalware they package with it?<issue_comment>username_1: When using apps which require certain permissions for the first time, the app asks you to grant the permission, which happens with stock apps too. If it doesn't, then permissions for stock apps can be managed in the App Permissions section of the Settings.

2015/12/14 | 360 | 1,438 | <issue_start>username_0: Is there a way of disabling auto-play of video in Chrome? Many sites have moved to HTML5 video and so you have ads or featured videos that start automatically playing the moment the page loads.<issue_comment>username_1: Starting from Chrome 47, there's a Chrome flag that is used to turn media autoplay on/off:
>
> Disable gesture requirement for media playback.
>
>
> Disable user gesture requirement for playing media elements. Activating this will allow autoplay to work.
>
>
>
You can see it by going to this link: [chrome://flags/#disable-gesture-requirement-for-media-playback](http://chrome://flags/#disable-gesture-requirement-for-media-playback);
The default status for the flag is disabled, so autoplay should not work: you should check your Chrome version and eventually update it. I tested with version 47 and autoplay does not work unless you turn on the flag.

Calibration of batteries (Li Ion or Li Po, used in almost all mobile devices) is a myth
You can start using it straight away and charge as you normally did with earlier batteries

[Looking for a consistent answer about battery calibration](https://android.stackexchange.com/questions/50469/looking-for-a-consistent-answer-about-battery-calibration?s=1|1.8341)
Using calibration apps doesn't really help as the battery files in system (to which these apps write) are renewed and previous data erased when you charge / reboot
As explained in this [article](https://plus.google.com/105051985738280261832/posts/FV3LVtdVxPT)

Related Myth : Charging a new battery for X hours
-------------------------------------------------
Charging a new battery for x hours before use is a "*legacy hangover*" from the days when Nickel Cadmium batteries were used. Those batteries had a "[memory effect](https://en.m.wikipedia.org/wiki/Memory_effect)". As a result, over a period of time, they "remembered" lesser battery capacity than rated capacity. To prevent this, it was advised to always fully charge these batteries
* This is not the case with Lithium Ion or Lithium polymer batteries. There is no logic to charge fully or x hours before use. Just use the battery normally, as suggested by others in comments
* [Table 1](http://batteryuniversity.com/learn/article/how_to_charge_when_to_charge_table) corroborates with additional information
Upvotes: 5 [selected_answer]<issue_comment>username_2: You don't need a calibration app for that. Just fully charge the battery to 100% (in one run), let it run down to below the 20% mark, the recharge it to 100% (again in one run without interception) – battery calibrated.
And as that describes a "normal day" with recent devices (take it from the charger at 100% in the morning, put it back almost depleted in the evening): No calibration needed at all, you calibrate it as a side-effect :)
All those calibration apps do in addition is removing the `batterystats.bin` file – which doesn't do anything to calibrate the battery (an [old myth](http://www.xda-developers.com/google-engineer-debunks-myth-wiping-battery-stats-does-not-improve-battery-life/) in fact).

### It's a sandboxed process from a *removed* app.
For such a number over 99000, it is the Unix UID for an **isolated sandbox process** (`u0_i70`).
In Android's UID system, called "AID". Android allocated 1000 special UIDs for isolated sanbox processes, 99000-99999. Some apps use that for security reasons, like Chrome (Incognito mode).

2015/12/16 | 2,939 | 12,100 | <issue_start>username_0: There are quite a few app based rooting methods. A recent review [9 free software apps to root Android devices](http://www.3ptechies.com/mobile/android/9-best-software-apps-to-root-android-devices.html), points to some of them and there may be more apps, paid or otherwise.
From what I understand,
**Plus Points**
1. Ease of rooting
2. Don't need a laptop or computer
**Minuses**
1. Based on exploits, so may not work if exploits are denied by OS updates
2. Difficulty in unrooting (as I see on some forums for my device Huawei Honor 6)
**Questions:**
* What are the pros and cons apart from above?
* If a device has both options - app based rooting and rooting by methods by developers, which one should I opt for?
**Note:** I am not seeking app suggestion or recommendation.<issue_comment>username_1: On request by OP, some details [from chat](http://chat.stackexchange.com/transcript/message/26321102#26321102):
Good question, but hard to answer: there are a few more things to consider.
1. it's not just "app based versus USB" – and even your "Difficulty in unrooting" is not necessarily the fault of "app based" in general, but rather that of a specific app causing that difficulty.
2. From a security point of view: if there's an app that can root my device – who says another app doesn't just do that without my consent? We all know there's malware out there doing exactly that (in order to integrate itself as system app, to be protected against factory-reset).
3. However, if there's no such app (and in the hope that's because it cannot be done by an app on this device/ROM), it's much harder for such malware. If then there's an easy method via USB, I feel a little safer :) It's rather unlikely some other app manages to attach an USB cable, download something to my computer, and runs that combo to do harm.
So above might count as "contra app-based" – but if such an app already exists for the device in question, there's not much we can do about. Even if we say "it's safer the other way round", that doesn't protect us against #2. Sure, we can check that before buying a device – but who says such an app doesn't pop up the day after?

**Answer:** It's all about malware vulnerability. Using Root exploits is a HUGE security risk and that over-weighs any other advantages
What is Soft Root and Hard Root?
--------------------------------
* **Soft Root :** Root is obtained directly by
running a piece of software (i.e., root exploits)- either by directly installing on the device or requiring `adb` shell through a PC connection
* **Hard Root :** Root is obtained by flashing su binary externally via an update package or ROM
Malware Threat - in general
---------------------------
* Even though legitimate, many convenient one-click root methods operate by exploiting vulnerabilities in the Android system. If not carefully controlled, such exploits can be abused by malware author to gain unauthorized root privilege.
* As described in the Android Malware *Genome Project* , **36.7% ( of 1260 ) malware samples had embedded at least one root exploit.**
* These well-engineered exploits are not well protected, it is extremely dangerous if they fall in the wrong hands.
Who are major root providers and broadly, how does it work?
-----------------------------------------------------------
[](https://i.stack.imgur.com/IiprN.png)
What are the types of root expolits ?
-------------------------------------
The paper covers 78 exploits studied. In general , the order of **impact** ( from the *highest to lowest*) :
* **Kernel Exploits:** Due to its privileged position, targeting Linux Kernel is natural to achieve full control over an Android device- example ,TowelRoot
* **Library Exploits:** the exploits targeting libraries that are used by Android system processes, or external libraries used for supporting different applications, example ZergRush exploit , libsysutils used by Volume Manager daemon
* **Application and Application Framework Application layer root exploits :** exploits targeting system applications or services, mostly include vulnerable logics introduced by `setuid` utilities, system applications, or services. example is a vulnerable `setuid` utility that is only present on XoomFE devices
that has a command injection vulnerability
* **Vendor-Specific Kernel or Drivers:** Vendors either customize the kernel (e.g., Qualcomm’s custom Linux kernel branch) or provide vendor-specific device drivers for various peripherals (e.g., camera, sound). Such code runs inside the kernel space and the compromise of which can also lead to full control over the device.
**Number wise** , exploits are as in figure below
[](https://i.stack.imgur.com/ptHUG.png)
How difficult is it to lay your hands on Exploit (Source or Binary) ?
---------------------------------------------------------------------
**Very easy.** Easily available from Google search, making it a cake walk for malware authors to leverage such exploits. Googling for 73 exploits lead to 68 of them being available - 46 with source code and 22 with binaries
How do these exploits work?
---------------------------
Major requirements for exploits to work (ordered from *most difficult to least*) ( [malware](/questions/tagged/malware "show questions tagged 'malware'") tag has a lot of these instances)
* **Requiring user interactions:** (6 out of 78 studied)
+ Asking the user to download an app and manually interrupt the installation
+ Asking the user to boot into recovery at least once .
+ Asking the user to manually put the device into “battery
saving” mode .
+ Asking the user to open a vendor specific app and hit a button
* **Requiring `adb` shell through a PC connection:** (17 out of 78 studied). For some exploits, `adb` shell connection is required because of the following most common reasons:
+ The exploit can successfully modify a setting in `local.prop` which enables root for `adb` shell only.
+ The exploit needs to write to a file owned by group shell and group-writable (not world-writable)
+ The exploit targets the adb daemon process that requires the attack process to run with shell user. For instance, the *Rage Against the Cage exploit* targets the vulnerability of adb daemon’s missing check on return value of `setuid()`
* **Reboot:** (6 out of 78 studied) Generally, many root exploits require at least one reboot. For instance, a symbolic link attack would allow an attacker to delete a file owned by system with weak permission, to setup a link at the same location to a protected file. After a reboot, the corresponding init scripts would attempt to change the permission of the original file to world-writable, which in reality changes the permission of the linked file
* **None or permission:** (44 out of 78 studied) The exploits in this category have no hard requirements, however, some of them may require certain Android permissions like `READ LOGS` in order for the process owner to be placed in certain user group.
Can these exploits be detected by Anti-Virus ?
----------------------------------------------
Since the root exploits are highly sensitive and may be leveraged by various Android malware, it is expected that anti-virus software on Android platform can identify most of them, including the ones implemented by root providers. Overall, the result shows that the state-of-the-art security products on Android platform still **cannot address root exploits effectively**
4 representative Android anti-virus products were used to test the *largest provider (name not revealed)* having 167 exploits. Because originally downloaded exploits from the providers database have packed the actual exploit code and employed a tamper-detection mechanism, study crafted 3 different versions for every exploit:
1. Original exploit fetched directly from providers servers, with
packing and tamper-detection on.
2. Unpacked exploit, which will expose all actual exploit logic to
anti-virus products.
3. Re-packed exploit with tamper-detection disabled.
Exploit binaries engineered by large root providers are surprisingly **“clean”** as all major anti-virus software have difficulty detecting them as table below shows

Conclusion
----------
Simple. Stay away from *Soft Root methods* unless you are capable of dealing with the consequences
Upvotes: 4 [selected_answer]<issue_comment>username_3: There are a few advantages to rooting using the official process.
1. It's officially supported on many phones. This means you can use a process that's documented by the manufacturer, and tools from an official source, or a trustworthy third party (CWM or TWRP), instead of having to run a tool that you got from some dodgy website.
2. Because it's officially supported, most of the time, a system update won't change the process, so you don't need to go looking around for "the latest" rooting method. In contrast, software updates tend to patch vulnerabilities, so exploit methods will often stop working after an update.
3. Because of the above, after you "soft root" you might be tempted to not install a system update, because that update patches the vulnerability and stops your rooting method working. With the official process, there's no reason to stay on an old, vulnerable version.
As well as the convenience of a one-click method (mentioned in the question), there are some other advantages of doing it that way instead.
1. Unlocking the bootloader to "hard root" wipes the phone, so you have to set things up again and restore data from backup. Typically "soft rooting" via a vulnerability doesn't need to wipe the phone, and that can be a lot more convenient.
2. Because rooting modifies the system partition, typically you can't do an OTA update afterwards: the updater recognises the system is modified, and bails out. But **some** "soft root" methods on **some phones** avoid this problem, so you can do an OTA update without having to unroot or flash a new system image. This is also a bit easier. Either way, you'll still have to root again after an update.
3. Since you don't have to unlock the bootloader, there's no temptation to leave it unlocked. This has the security benefit that people can't flash new ROMs to your phone (e.g. if it is stolen and they want to circumvent the screen lock or factory reset protection).
What Beeshyams says about security is important, but to my mind it's irrelevant to the question. It's good to point out or remind people that every "soft rooting" method is exploiting a security vulnerability, and malware could use just the same vulnerability to install rootkits on your phone. However, the vulnerability is there whether you use it or not. The security risk comes from the **possibility** of the rooting method. Rooting your phone by exploiting the vulnerability doesn't make it more exploitable, or worse.
If your phone **can be rooted** by a rooting app/exploit, then it is vulnerable to malware. This is true just the same regardless of whether you root it or what method you use. Not using the exploit (by doing a "hard root" instead, or just by not rooting) will **not** protect you from malware, **nor** will it reduce your exposure.

2015/12/16 | 806 | 3,273 | <issue_start>username_0: I plan to install Cyanogenmod on my new Android phone. For this first install, I've to do a factory reset - what's no problem on a factory new phone.
But do I have to perform this factory reset on every minor and major update of the mod in the next month and years - and loosing all my app settings, logins, game highscores etc. again and again?
Or does the Cyanogenmod update behave like a normal Android update (just a little bit downloading, rebooting and continue with all apps and settings as before)?<issue_comment>username_1: Generally speaking **you don't have to perform a factory reset when downloading a newer build**. The flashable zip should perform all wipes by itself if it is necessary (only certain partitions are affected - your data should be safe). Many developers include an OTA(Over-The-Air)Update Application so you can comfortably download and install the new build with 1-3 clicks. It depends on which device and which custom rom you are using.
In most cases you only have to perform a factory reset
1. when you're performing a fresh installation of CM
2. the android version changes(factory reset may not be needed but it is adviced most of the times)
3. when something goes wrong :)
The best thing to do is to make regular backups and save them on your computer - this way you won't loose much.

To answer your question now, avoid nightly/ experimental/ snapshot builds, install only stable builds and update as recommended by CM installer or manually as highlighted.
***Generally* minor updates and nightly builds do not need factory reset**
This is about official builds. If you are sourcing your build from other developer forums follow their instructions

I have no clue on how to proceed next. Does anybody here have a fix? I want gapps installed on my device.<issue_comment>username_1: You could try replacing the CM recovery with TRWP and flash open\_gapps with that. My OnePlusOne has TWRP and flashing open\_gapps worked fine.
The disadvantage is that you have to reboot into recovery to flash the CM updates.
Upvotes: 2 [selected_answer]<issue_comment>username_2: I was able to to keep the CM recovery and load Open GApps as long as I side-loaded both of them at the same time using `adb`. In other words, load **both** the CM `.zip` and the Open GApps `.zip` before you reboot.

2015/12/16 | 594 | 2,465 | <issue_start>username_0: I paired a BG-BluBox external sound cube to a Samsumg Galaxy Note 10.1 2014 Edition successfully.
At a later time, I initiated a pairing of the BG-BluBox with a Samsung Galaxy S5 (Android 5.0). The pairing was not successful\*. I am now unable to pair this device with the S5.
I have located the Bluetooth app under Device Manager and have deleted data and cache and restarted the device.
I have also wiped the cache partition.
In both of the above cases, the outcome is the same. The Bluetooth app on the S5 still shows other paired devices as before, shows the BG-BluBox, but the S5 reports that the PIN/password is incorrect when I try to pair.
How can I pair this device with the S5?
\*I may have had to enter a PIN, which I may have entered incorrectly. This was a while ago and I don't recall the details now.<issue_comment>username_1: Based on our chat discussion, consolidating
1. By entering PIN correctly on the sound box, you are able to pair with S4 or any other device
2. This doesn't repeat with S5, even after clearing the cache and data of S5 (The first way is to to clear cache and data of Bluetooth app from Settings > Applications Menu > Application Manager.
3.There is no option of resetting memory of sound box and it remembers the last known good connection, which in this case is S4
Available information points to a problem with S5 persisting to remembering the wrong PIN entry and attempting to pair
To fix this,(Considering your device is NOT rooted), would suggest to factory reset your device after taking back up of data and attempt to pair
**EDIT**: You had mentioned that clearing Bluetooth app data/ cache **did not** clear the saved settings for S4. Which makes me suspect that cache of app is not being cleared. Suggest try this to clear cache of your device -turn your Samsung Galaxy S5 off and press at the same time Power + Home + Volume Down buttons to enter in Recovery Mode. Inside Recovery Mode press “Wipe Cache Partition” and reboot your phone. This option I understand had not been tried. You will not lose data. If this also doesn't help, factory reset would be the last resort
Meanwhile, you can mail OEM of sound box to get instructions on resetting or clearing it of stored device information and do that as well to have a clean slate

2015/11/17 | 1,785 | 6,482 | <issue_start>username_0: I have an nVidia Shield TV device, which is running Android TV.
In order to integrate this into my home theater setup, I need to be able to determine if the device is active or sleeping.
For my other devices I just use ping to determine this. However, since Android devices are basically always on, this doesn't work in this case.
One way, of course, would be to write a simple app, which opens a TCP port when the device is active and closes it when it's sleeping.
My question is if there's a simpler way, maybe an existing app or some other way to do this without developing my own app to do this.<issue_comment>username_1: This is not actually a solution but in device settings there's probably an option which disables Wi-Fi when device goes to idle mode. Even if there's no such option I'm sure there must be an application for this. So if Wi-Fi is disabled in IDLE state then "ping" approach will work but you have to deal with unworking background updates and so on when device goes to IDLE state.
I don't think that there's a default application for this solution but maybe further point will help you. You can create your own Android application which listens to [PowerManager.ACTION\_DEVICE\_IDLE\_MODE\_CHANGED](http://developer.android.com/intl/ru/reference/android/os/PowerManager.html) `Intent` and upon receiving receiving some kind of request from your server it can send back if device is awake or not. However notice that when your device receives server request it will probably come awake.

Query system services
=====================
Enable [adb](/questions/tagged/adb "show questions tagged 'adb'") in wireless mode on device. Follow the [official guide](http://developer.android.com/tools/help/adb.html#wireless) or [this answer](https://android.stackexchange.com/a/116023/96277) of Izzy for instructions, if needed.
You can find the status of Android - sleep or awake - from the dump of various system services.
* Service: Power
```
adb shell dumpsys power
```
Search the strings `mWakefulness` and/or `Display Power: state`. Both of them would give you the status you need.
Example:
```
adb shell 'dumpsys power | grep -e "mWakefulness=" -e "Display Power"'
```
gives me
```
mWakefulness=Asleep
Display Power: state=OFF
```
* Service: Window
```
adb shell dumpsys window
```
Search the strings `mAwake=true` and/or `mScreenOnEarly=true` and/or `mScreenOnFully=true`
Example:
```
adb shell 'dumpsys window | grep -e "mAwake=" -e "mScreenOnEarly" -e "mScreenOnFully"'
```
gives me
```
mAwake=true
mScreenOnEarly=true mScreenOnFully=true
```
* Service: Display
```
adb shell dumpsys display
```
Search the strings `mState=OFF` and/or `mScreenState=OFF`.
Example:
```
adb shell 'dumpsys display | grep -e "mState=" -e "mScreenState"'
```
gives me
```
mState=OFF
mScreenState=OFF
```
---
Use Automation
==============
If none of the system services mentioned in previous method worked for you, setup an [automation](/questions/tagged/automation "show questions tagged 'automation'") app, such as Tasker or MacroDroid or Automate.
We would now use automation to write the status of Android into a file, such as Sleeping for sleep mode and Awake when it is awake.
### [Tasker](https://play.google.com/store/apps/details?id=net.dinglisch.android.taskerm),
* Profile: Event → Display → Display Off
* Task: (Actions) : File → Write File → select a text file to write into, type Sleeping and uncheck Add Newline
* Profile: Event → Display → Display On
* Task: (Actions) : File → Write File → select a text file to write into, type Awake and uncheck Add Newline
### [MacroDroid](https://play.google.com/store/apps/details?id=com.arlosoft.macrodroid)
Android sadly doesn't come with `echo` or `printf` utility, If the device is rooted then you can install [busybox](https://play.google.com/store/apps/details?id=stericson.busybox) and be at peace. If not, download busybox [binary](https://busybox.net/downloads/binaries/latest/), set executable permissions and push it into `/data/local/tmp` using [`adb push`](http://developer.android.com/tools/help/adb.html#copyfiles). Another way for a non-rooted device is to keep three files, one for state, one with the text Sleeping and and the last one with the text Awake. Whenever the screen turns off/on, copy the second/third file into first one.
MacriDroid also requires a plugin, such as [Secure Settings](https://play.google.com/store/apps/details?id=com.intangibleobject.securesettings.plugin) to execute commands.
* Trigger: Screen On/Off → Screen Off
* Action: Secure Settings → Actions → Run Command:
+ Command: `echo Sleeping > FILE_PATH`
+ Command Name: Screen off
* Trigger: Screen On/Off → Screen On
* Action: Secure Settings → Actions → Run Command:
+ Command: `echo Awake > FILE_PATH`
+ Command Name: Screen off
For a non-rooted Android, `echo` should be replaced with `./data/local/tmp/busybox echo`. Otherwise, do a copy operation using the command `cp SOURCE DESTINATION`.
### [Automate](https://play.google.com/store/apps/details?id=com.llamalab.automate)
Your flow should more or less look like this image
(Click image to enlarge)
[](https://i.stack.imgur.com/jqP1t.png)
Your need to create two flows, one for sleep and other for awake. The second block in the flow is named *Broadcast receive* and can be found under Apps. The third block is named *File write text* and can be found under File & Storage.
You can now check the content of that file using adb in wireless mode or using SSH (requires an [SSH server](https://play.google.com/store/search?q=ssh%20server&c=apps) on Android; run the server on all interfaces and do not bind it to a single interface.)
---
There is another possibility, such as making your automation app upload the file to a local or remote server so that you can query that server instead of Android to know status.

Your need to create two flows, one for sleep and other for awake. The second block in the flow is named *Broadcast receive* and can be found under Apps. The third block is named *File write text* and can be found under File & Storage.
You can now check the content of that file using adb in wireless mode or using SSH (requires an [SSH server](https://play.google.com/store/search?q=ssh%20server&c=apps) on Android; run the server on all interfaces and do not bind it to a single interface.)

There is another possibility, such as making your automation app upload the file to a local or remote server so that you can query that server instead of Android to know status.

2015/12/16 | 632 | 2,297 | <issue_start>username_0: I want to record some of my public speaking using a lapel mic while walking away from my android smartphone. I've done this using a standard bluetooth headset. However, the audio is pretty poor. So, I'd like to purchase a better quality microphone (probably a mic that attaches to my shirt). The reviews on amazon for bluetooth mics are pretty bad. The best reviews for this type of mic are mics that have 3.5mm output. I'm wondering if there is a way to convert that into a bluetooth signal that is sent to my phone for recording. I've seen that bluetooth adapters exist, but those seem to be all about hooking up to bluetooth headphones. I've been googling trying to figure out how bluetooth works (receivers, transmitters, etc), but I can't find out if this will work... and I can't seem to find if anyone else is doing it successfully. Any help is much appreciated.<issue_comment>username_1: OK, so I have an ANSWER. I know for sure that the Pryme BTH-300 can accept a microphone plugged in via 3.5mm and sent the external mic's audio to a device via bluetooth (I have one myself). The only bummer of the Pryme BTH-300 is that the audio output, if you're listening to music, for example, is poor.
I'm going to try
Sony RM-X7BT
which has a microphone input as well as an output that it can send via bluetooth to your phone. I'll try to post on here my findings, but on Amazon for sure.
Upvotes: 1 <issue_comment>username_2: I believe a number of the products from JK Audio may be helpful with this specific use case. Specifically, their [BlueDriver-F3](https://www.jkaudio.com/bluedriver-f3.htm) which is a female XLR-adapted device that can plug into a mic and send the mic signal to a phone (or speaker) via Bluetooth. There are other "Bluetooth Wireless Audio Interfaces" (useful search term) that may work as well.
There are plenty of converters to go from a 3.5 mm output to an XLR male output so that you could use the BlueDriver-F3 with a lav mic with a 3.5 mm output. For example, the [Rode VXLR Adapter](https://www.bhphotovideo.com/c/product/387850-REG/Rode_VXLR_VXLR_Mono_Mini_Jack.html).

2015/12/17 | 590 | 1,908 | <issue_start>username_0: I'd like a phone, preferably Android, with 256 GB of storage.
To the best of my knowledge, no 256 GB microSD cards exist (despite a few [scammy Amazon listings](http://rads.stackoverflow.com/amzn/click/B017C8XH02)). Therefore, the phone would either need to have (1) a fullsize SD slot or (2) dual microSD slots. I don't know of any android phones that have a fullsize SD slot, although there are of course tablets that do. And the only Android phone I know that promised dual microSD cards is the [vaporware Saygus V2](http://www.androidauthority.com/saygus-delays-what-is-going-on-650149/).

Though currently, I don't see cards with a capacity of more than 256GB.
Upvotes: -1 <issue_comment>username_2: [A quick search on Amazon](https://www.amazon.com/s?field-keywords=256GB+microSD) gave a bunch of results.
* SanDisk Ultra has a 256GB model (red and pale yellow)
* Samsung EVO+ has a 256GB model (red)
* Samsung EVO Select has a 256GB model (green)
* Other manufacturers also have 256 GB models, e.g. Patriot LX and ADATA Premier
* Lexar has 256GB models but I've heard they're ceasing producing storage products
Oh, there's one more thing that I'd like to note: The "maximum supported storage capacity" actually depends on the SoC (chip) and system. So as long as your phone is running on an SoC later than 2015 and Android 5+ (Lollipop) then it should have no problem supporting a 256GB microSD card.

2015/12/18 | 583 | 2,342 | <issue_start>username_0: I have had a constant nightmare with not being able to take OTAs on any of my (rooted) devices. They boot into TWRP, complain about the build fingerprint, and won't install, so I have to wait for a full .zip and flash my systems manually.
What is it that is preventing the OTAs from installing over a modified /system partition, and why can't it be defeated or disabled?
If it can't be defeated/disabled, why can't my modified /system lie about its build fingerprint to fool this validation into allowing the OTAs to be installed?<issue_comment>username_1: OTA files work by patching files rather than replacing them will a full copy of the new version of the file. This means that it has to verify that the existing files are exactly as it expects or the patching process won't work (or could cause the file to become corrupt). If you were to fake the fingerprint and force the OTA to apply you might end up with a device that can't boot due to some files being corrupt.
Android 5.0 (i think) switched from verifying just the files it was patching to verifying the partition as a whole so any modification (even to a file that is not being patched) will cause this to fail.

1. OEMs like Samsung have Knox counter which gets tripped once you root or replace stock recovery by custom. There were work around earlier to this, but Note 4 onwards tripping Knox "burns" this information into the hardware. Only way to revert Knox status is by changing that chip on the motherboard !!(I am not aware how this is achieved but it is on record as a mail reply from Samsung ). I expect OTA to verify this first
2. OEMs like Huawei (my current device is Honor 6), allow you to unlock boot loader and cover it by warranty allowing OTA updates if rooted but stock recovery intact. Replacing recovery fails OTA
3. I suspect carriers which "lock-in" their customers will also employ their own means to verify before allowing OTA (probably this is one reason why there is a varying delay in carriers rolling out OTA)
So it may not be a simple solution to have the recovery trick OTA...too many tricks to learn and proprietary ones, which is NOT the purpose of TWRP

2015/12/18 | 411 | 1,513 | <issue_start>username_0: Some providers offer a "data only" sim card. Do these types of sim cards have a phone number assigned to them? If yes, what happens if a dial out is attempted of if there's an incoming call?<issue_comment>username_1: Usually, they have. Usually, "data-only SIM" only have a special tariff plan with cheap data service rates, and is an ordinary SIM from all other points of view.
Finally, it fully depends on cellular provider - it can allow voice services, or it can prohibit them.
So, the only way to get a correct answer is to try.
Upvotes: 2 <issue_comment>username_2: Yes, they do have number, perhaps, *special* number, taken from a specialized pool of numbers, allocated for certain purposes, such as assigning tailored tariff plan to them.
You might hear of "Numberless" sim cards [in some parts of the world](http://mybroadband.co.za/news/cellular/8152-mtn-numberless-sim-system.html), however, these sim cards aren't entirely numberless. You'll **need** a number to actually use it.
Upvotes: 2 <issue_comment>username_3: A number has to be assigned so that the (rather old) system can recognise the SIM.
Just because it has a number though doesn't mean that any calls can be made or received and will already have been disabled by the network.
The provider can add services as wanted/needed though: SMS can be useful for [managing routers](http://www.draytek.com/index.php?option=com_k2&view=item&id=5765:how-to-command-vigor-lte-router-by-sms-message?&lang=en).

I have 3 e-mail addresses, all of those I wish to keep in my Gmail app (I did that in an older phone I had), so I go to "Add Account" in the Gmail app, click "New Account" and...
I'm taken to a "Confirm your Password" screen. And there, I type my password... Only to see a "try again" prompt. And no matter how many attempts I do, all I see is a "try again" prompt. My research led me to know that a "2 step verification" can be the issue, but turns out it's deactivated on ALL 3 OF MY ACCOUNTS!
I also can't add other accounts to my Youtube app, which I need since I need to publish videos while away from my PC. Here's an image of that confirm your password screen. If anyone has any suggestions, I'll be thankfull (just a warning: I'm a noob, so I'd appreciate "simpler" language if possible).
Also, if it helps, the main account is my personal e-mail. I'd like to add 2 "workplace" e-mails to the Gmail app, and one of those is linked to a Youtube Account.

Why do you go to "New Account" if you **already** have 3 email address?
This is how on my 5.1.1, Adding an account works:
* I go to Settings > Accounts > Add Account > Google > 'Enter email' > 'Enter password' > Logs me in
The steps you're describing isn't available, as you only need to confirm your password when creating a New Account, and not when logging into an already created account.
If you see "Confirm Password", then you're not *logging in*, but rather, *creating an account*, in this case, a 4th Google account.

I know that it's not possible to do that without root access but the device is rooted.<issue_comment>username_1: Google changed the USB protocol for Marshmallow to always default to charge.
The reason for this change because they brought back the ability to make external storage (SD card) become internal storage. Creating a new storage type called "Adoptable Storage".
Originally google removed the ability to swap storages because they viewed it as a huge security vulnerability.
[Adoptable storage](https://source.android.com/devices/storage/adoptable.html)
In order to achieve your end goal it looks like you might have to compile marshmallow from source. Find the `MtpService.java` and then with `updateDisabledStateLocked()` change `mMtpDisabled` to `false`.
[MtpService.java](https://android.googlesource.com/platform/packages/providers/MediaProvider/+/4599003425f9b83319805a3522aeb31bfd2f1d30/src/com/android/providers/media/MtpService.java)

Follow this steps to fix this:
**Turn off your device**

2. Wait for the screen with the three Android images to appear, and then release the **POWER** and **VOLUME DOWN** buttons.
3. Press **VOLUME DOWN** to select FACTORY RESET, and then press the **POWER** button.
The **boot** may take some minutes

Open up the device manager from a desktop computer and set a temporary password on the phone. You can use that temporary password to get past the lock screen.

If I open the Misc. category there is no files displayed that can fill up that much space (the same thing goes for ES File Explorer SD card analyst).

Here should've been another image to illustrate the situation with analysis from ES File Explorer SD card analyst, but I don't have enough karma for that.<issue_comment>username_1: Consider these possibilities:
* Do you have "Recycle Bin" enabled in ES Explorer? If so, check the Recycle Bin folder. Its easy to forget sometimes that your deleted files aren't actually deleted when using ES.
* If you wiped-clean or reset your phone to factory recently, it might be keeping your previous data somewhere, normally in a `.android` folder somewhere.
* Also you can enable to show hidden files in ES Explorer, maybe might give hints.
* ES Cleaner too, run it and see what it finds and thinks you can clear. Most times, it provides the link to the directory where the files tantamount to cleaning are.
I can think of the above now. I hope it helps

[](https://i.stack.imgur.com/o4jyS.png)<issue_comment>username_1: If you backed up the apps you removed, you should be able to just adb push them back to the device OR copy/paste to the system app directory if that's available from Windows/Linux (etc) file explorer. Assuming all you did was delete some apk's.
If you didn't and you can find a stock rom, you might be able to do the same but instead getting the apk's from the rom.
Its possible that doing so may not work (depending on how the rom is set up and what you have available) and that you need to (re-)flash a rom (even just a dirty flash of the same rom or newer should get you back in).
But what you should have done was a full backup via adb, made sure there was a rom available for flashing, or installed a recovery and made a full backup before messing around in the system section. BACKUP backup backup!
A more direct answer may be obtained from the device thread on xda website where multiple people likely know the device well enough to get you through it.

You might want to bring it in to the Google Store. This is why you do not mess with system apps! It brings a lot of trouble to your phone.
Now, if you deleted the apps because you wanted storage, That is not a good idea, because your phone may overflow with downloaded with apps and games, which is not healthy for your device. Bringing it to the Google Store, they may fix your problem.

3. Go to device manager and click "Action" > "Add legacy hardware"
4. Install the oracle virtual box adapters manually (my path was `C:\Program Files\Oracle\VirtualBox\drivers\network\netadp\VBoxNetAdp.inf`)
Now that VirtualBox adapters are installed correctly, it needs to be setup correctly. (the following solution is like many other solution in here)
1. Start Oracle VM VirtualBox dependent Genymotion, and go to "File" > "Preferences" > "Network" > "Host-only Network"
2. Click "Edit"
3. Set IPv4 192.168.56.1 with mask 255.255.255.0
4. Click "DHCP Server" tab and set server address: 192.168.56.100, server Mask: 255.255.255.0, lower address bound: 192.168.56.101 and upper address bound: 192.168.56.254

How do I clear app cache/data on Android without accessing settings?<issue_comment>username_1: Quoting from official Cyanogen site

"Delete all the lines after "ui\_print("Verifying the updated system image...");" until "show\_progress(0.020000, 10);". once you have done it save the file and copy it back into the location inside the rom zip file and flash it on your phone."
Worked for me.

* Will the preloaded apps be restored?
* Will my device remain rooted or will I lose root?
**Device**: Samsung Galaxy Note 1 (GT N7000)<issue_comment>username_1: Your phone will be unrooted and apps will install again.
Upvotes: -1 <issue_comment>username_2: There are two parts to your question
1. **Factory Reset**.
a) Factory reset removes user data including apps installed by the user on phone. Since your device is rooted, you can see that everything in `/data`
and `/data/data` will be wiped.
b) Factory reset does **not** flash stock ROM. Since you have deleted preloaded apps, they will **not** be restored. If you want them restored, you have to flash stock ROM
To understand more about factory reset, please read this
[Factory reset to restore performance? What are the disadvantages?](https://android.stackexchange.com/questions/12802/factory-reset-to-restore-performance-what-are-the-disadvantages)
2. **Root**. You will **not** lose root on factory reset. Your phone will remain rooted
Please read this post to understand more [Can I safely do a factory reset without losing root?](https://android.stackexchange.com/questions/100996/can-i-safely-do-a-factory-reset-without-losing-root)

2015/12/21 | 1,278 | 5,105 | <issue_start>username_0: I installed CM 13.0 onto a Nexus 6, which includes Android 6.0.1, and I have set a PIN. The Settings UI reports that my phone is encrypted.
However, my phone is able to boot all the way to the lock screen without entering my PIN. This seems to imply that only `/data` is encrypted. I was expecting that I would have to enter a PIN at boot time, the way I did with Ice Cream Sandwich and Lollipop. Furthermore, when I go to TWRP, I can see all my files without ever entering a PIN.
My understanding was that Marshmallow required full disk encryption, and that full disk encryption would require a PIN at boot time to decrypt anything useful.
What did I misunderstand here? If someone stole my phone and didn't know my PIN, what would they have access to?<issue_comment>username_1: I do believe the password you had entered was Encrypt Device Data which in turn does what is below, not screen lock
If you have gone into settings and encrypted your device please note that **IF** your device had the function of Mass Storage, that feature will now be disabled as Media Storage will be the only thing you can use(media storage: add videos and or music by computer media software; no adding other folders and or files manually, ect.)
Encrypting a device and or SD card locks specifically 3rd party software and or computer interaction from getting access to the device, device files and or prying eyes let alone access to folders you once could by connecting to your computer.
To undo this that I have found useful and possibly the only way:
Format Encrypted Device
SD Formatting wipes out all user data like a clean slate and or like a new card
Device formatting wipes **ALL** user account information including all files like Music, Photos, Videos, ect.
It is recommend to backup these files before formatting any of the two (2)
To backup
* Settings
* Backup and reset
Make sure **Backup My Data** is checked
Make sure **Backup Account** is correct
Make sure **Automatic Restore** is checked
Automatic Restore: Restores user account(s), system data, downloaded system apps, restores system pictures, system videos, system music, and or anything else that was saved to the **system only**
**IT IS RECOMMENDED TO RESTORE OVER WI-FI, IF YOU USE CARRIER DATA CHARGES MAY APPLY**

Nexus devices with L or M had forced encryption at first bootstrap - that is, forceencrypt flag is present in fstab.qcom, so your device is automatically encrypted.
In those cases, master key is encrypted with default password, which is
```
<PASSWORD>
```
Most probably, when you had set lock screen PIN, you haven't selected *Require PIN to start device*, hence, there is no preboot authentication.
In regard to FDE, in AOSP ROMs only /data is encrypted; but there are solutions for [LUKS](https://github.com/guardianproject/LUKS) or [PBE](https://github.com/GNUDimarik/Mobiflage) that are not user friendly. Several years ago, [WhisperCore](https://www.cnet.com/news/whispercore-app-encrypts-all-data-on-android/) was launched and abandoned.

[](https://i.stack.imgur.com/BYbjp.jpg) [](https://i.stack.imgur.com/u59WA.jpg) [](https://i.stack.imgur.com/26pfa.jpg)
But protecting your device is your choice. The system wants to give you liberty to do what you like so it won't enforce data security even if encryption is available. When setting lock screen security, there's a question about, liking to protect your device by asking a pattern, password or PIN. This means when device switches off, and this option is on, it runs an encrypting script so as on the next bootup the phone demands the pattern to decrypt. Even TWRP will ask you for a code so as to mount `/data`. Note that if the whole root partition is encrypted, the device won't even use the **boot.img** and recovery since they rest at `/dev/platform/[memory.name]/by-name/boot.img` and `/dev/platform/[memory.name]/by-name/recovery.img` hence encryption only affects the `/data` partition, anyway, encryption is for protecting your data from unauthorized access not the system from accessing it's runtime essentials. Failure to agree to that prompt well count your device as decrypted and it's not encrypted on shutdown again hence it behaves like a decrypted device which is put aware to you when it tells you, "device protection features will not work on this device". That's what Android does, if you want a more practical visible type of encryption try BlackBerry 7 OS encryption and it's precedent devices. It will encrypt media, sdcards, and they won't even work on your computer through drag to copy. Unless you send then by bluetooth or any recognized upload.

Apparently, pressing the "Xcover button" on the side of the phone will now toggle the flashlight on and off even in the lock screen.
I've tried to find some way to turn this behavior off, but I'm not seeing anything in the settings that would look promising. My attemps to Google for a solution just yield instructions for *enabling* flaslight access from the lock screen on versions *prior to* Lollipop.
Short of getting a more robust case for my phone, how can I keep my pockets from shining in the dark?<issue_comment>username_1: I had this same problem, and found a solution!
Download a random app (one that you don't actually need) from Play Store, then go to Settings (*Personal* / *Xcover key*) and change the button to open that app. Test that it works, and then delete the app, and now the button does nothing. ;)

2015/12/23 | 592 | 2,221 | <issue_start>username_0: What I have found recently: In order to save space on my device (Galaxy S5) I attempted to use the 'move to SD card' option. This has not really helped all that much. It seems that it uncompresses an application, making it a lot larger before moving a chunk of it to the SD card.
What I am asking is about the option that is available via a rooted phone. Does the rooted version offer a better solution, such as moving more of the app to the card? Or is it not worth the effort to root the phone for that choice?
My phone is I am certain long out of warranty so not really worried about that.
It is clear to me there also may be multiple different tools that do this. It would be helpful to find which may be the best choices. Thank you in advance.<issue_comment>username_1: Link2SD is a great **root** app that move the files 100%. I had it and saved a lot of space! but for now I don't need it. You will need to use a tool to edit the partitions on you SD card to make Link2SD work. I'm not sure if any of the tools running on Android will work correctly. There is a "Link2SD tutorial" available.
Just one bad thing about Link2SD : It is not free.
Upvotes: 1 <issue_comment>username_2: The "Move to SD card" neither moves the app (APK file) nor the complete app data.
It just moves the additional media files and data (that doesn't pose any security risks upon revealing to user) like Images or Graphics or whatever.
(And all apps do not provide this option. It depends on the app developer.)
These moved data can be found in the Memory Card in a directory named *Android/data* .
And yes, the rooted solution moves the complete app and app data into your memory card, which completely lessens the burden.
But you have to [create a separate EXT2/EXT3/EXT4 partition first in your memory card](http://www.wikihow.com/Use-Link2SD#Creating_Another_Partition_sub) (using softwares like [MiniTool Partition Wizard](http://www.partitionwizard.com/)) and then use an app like [Link2SD](https://play.google.com/store/apps/details?id=com.buak.link2sdplus&hl=en) (as @Tamoghna said) or [**Mounts2SD**](http://forum.xda-developers.com/showthread.php?t=2432479).

=======================
If you are root you can backup/ restore all partitions (not only recovery) with native tools.
To list all mountable partitions and block devices use `find` and `grep`
```
adb shell
su
find /dev | grep by-name$
```
On my system I get `/dev/block/platform/soc/1d84000.ufshc/by-name` back (this is very device specific and yours may look different).
Now You can list `ls` this path to show all mountable partitions.
```
ls -al --color /dev/block/platform/soc/1d84000.ufshc/by-name/
```
Or all in one command
```
ls -al --color $(find /dev|grep by-name$)
```
Backup
------
Armed with this information you can, as root, backup all partitions. Just use the `dd` (part of every android toolboox/ toyboox e.g.:
```
dd if=/dev/block/platform/soc/1d84000.ufshc/by-name/recovery of=/sdcard/Download/recovery.img.dd
```
Restore
-------
>
> **Warning**
> Data lost possible! Don't use until You understand all `dd` parameter.

In many cases you can also **restore** with the `dd` tool, e.g:
```
dd if=/sdcard/Download/recovery.img.dd of=/dev/block/platform/soc/1d84000.ufshc/recovery
```

```
fastboot boot twrp.img
```
This remote-boots the custom recovery partition so you leave the stock recovery partition intact.
Now you root the phone.
Reboot the phone.
adb shell
su
Use dd command to copy the recovery partition.
If you have already flashed a recovery partition then it's too late. You will have to find a stock recovery partition for your phone somewhere on the [interweb](https://dictionary.cambridge.org/dictionary/english/interweb).

2015/12/23 | 544 | 2,032 | <issue_start>username_0: I have a bricked android BLUBOO X2. I rooted it, changed build.prop to set some settings so that I could boot in Ubuntu Touch(which didn't work). And now I can't boot up anymore at all, it is in boot loop.
I tried booting in recovery and then selected "apply update from ADB". It then says: 'Now send the package you want to apply to the device with "adb sideload < filename>" ... '. I did this once and it showed an error, but the weird thing/problem is that I cannot sideload anything anymore: 'error: device not found'.
I (think I) know it is connected with my (Windows 10) PC because it made a connection and deconnecting sound when booting in recovery.
How can I get my android to be connected or how otherwise can I load a ROM or change the build.prop back?<issue_comment>username_1: Well, you've just messed with the system partition, so there's nothing much to panic.. Here's a stock ROM for your phone:
<http://www.needrom.com/category/bluboo/x2-bluebo/> (Choose the ROM for the SAME android version you had before bricking).
The good news is you won't need to lose your data. Everything will be safe.
Download SP Flash Tools, load the scatter file from this ROM, uncheck all the partitions except ANDROID (SYSTEM) as this is the only partition you need to rectify. Click on Download and connect your device. Your device will be unbricked without having to lose any data.

Every time I turn on the screen, the battery drops 1%. For example, the battery is 30%. then I close the screen and turn it on again after a minute, and then in few seconds,the battery becomes 29%. It only happens when I turn on the screen, but when im using it, the battery discharge is normal. How can I fix it?<issue_comment>username_1: Based on our chat, things which were tried are:
* Turning *off "proximity sensor" and "Smart Stay"* (to rule out malfunctioning causing battery drop h
* Checking screen usage from inbuilt battery statistics (seemed to match usage)
* Booting into safe mode and observing battery drop
* Factory reset to rule out rogue app causing this
OP has confirmed that the **Battery drop continues** as stated in the question
Being a new phone, it could either be
* ROM bug, which can be checked from user forums. If it is a reported bug add if the OEM rolls out a fix then the problem is solved
* Defective piece, which being in warranty can be exchanged (**Recommended** course of action on my opinion)
(Flashing stock again is an option but do not advise it as rooting methods, flashing tools etc may not be readily available being a lesser known phone My25 (myphone). Flashing a custom ROM for the same reason and absence of developer support , is not recommended)

I need this because I want to transfer files larger than 4GB on my phone microSD card, but FAT32 allows just files up to 4GB.<issue_comment>username_1: Honestly speaking, It depends on the manufacturer. As far as I am aware, the company has to get some license from Microsoft to include NTFS support. Speaking from experience, most (high-end) Samsung and HTC phones do while custom roms typically do not.
The only sure-shot method to confirm is by trying it out with an extra sd card...

The body looks new so I don't mind keeping it but I am worry about malicious software/apps. I know I can factory reset the phone, but is there any way to tell if the ROM is original?
FYI, the phone is a Moto G 2nd gen w/ 5.0.1 lollipop.<issue_comment>username_1: TheBro21's comment applies only if it's a KNOX enabled device. For most Android devices, when you boot into downloading mode it will read a few lines in "SYSTEM STATUS: custom" or "Custom Binary Download YES (and the number of time here, if it hasn't be reset with triangle away)". If in bootloader mode it says `Unlock state: true`, it might be that the ROM is custom, but then again it may have been done by a stock flash.
You can also go into the settings and about and look at the system status, ROM, kernel, or base-band and if it has a weird name, google it, it's probably a custom ROM or kernel, if not, it probably isn't or close enough you'd never notice.
If you really are concerned and want a fresh device on official firmware, google how to flash your device with Odin, than download the latest stock firmware.

You can
* Factory reset your device (of course after taking back up of data )
* Root your device, flash a custom recovery and take a complete back up of your device with [TWRP](https://twrp.me/devices/motorolamotog2014.html)
* Generate MD5 check sum using TWRP or alternate apps like [Hash Stamp MD5 & SHA1 generator](https://play.google.com/store/apps/details?id=leonidpeter.hashstamp)
* Download [stock lollipop](http://www.guidingtech.com/38303/restore-moto-g-stock/) (assuming that your device variant matches with that mentioned and the ROM version on your device matches)
* Generate and verify stock MD5 and SHA1 with TWRP nandroid back up
* If it matches, it is confirmed both are same and no tampering took place
* If not flash only kernel from TWRP, and generate MD5 and SHA1. Repeat with downloaded image and verify
* Repeat above with `/sys` and `/data`
* This should pinpoint the tampering that happened
It is a little tedious but IMO, worth the effort as it proves beyond doubt that either present ROM has not been tampered with or if tampered, in which portion (s) of the ROM it happened. This may not be a practical solution but is based on the premise that (near) fool proof validation is only possible when compared with original stock ROM. Other variations of this could be see if OTA updates work or comparing partition sizes

But, if you want to be 100% sure it was not tempered, I would suggest to manually download the official ROM and flash it. This does not void your warranty and AFAIK all phones can be manually flashed with official software.

This is how I would proceed. If the official stock ROM is available from trusted sources, you can download it and verify the integrity of the binaries on your phone by comparing it's MD5/SHA checksums with that of the one you downloaded.
But in your case, if the official ROM is available you could simply flash it and you can use your phone safely. But in case the ROM is not available(or even if it is available), the most safest option for you is to download the Official CyanogenMod ROM for your device and flash it. It will keep your phone free of "malicious software/apps."

2015/12/23 | 1,007 | 4,065 | <issue_start>username_0: Normally I can reinstall (preserving application data) APK only when it's signature matches the previous one.
How do I force upgrading of the application signed with a different key (for example, from a distribution version to a self-compiled version, for example) without removal of the data (i.e. uninstallation) using root access?
Workaround is backup application's data + uninstall + install + restore data, but that is inconvenient and notifies other applications about [un]installation which is not intended.
Ideally this should be a one-off exception that I personally approve, not just disabling of the whole signature verification mechanism.<issue_comment>username_1: TheBro21's comment applies only if it's a KNOX enabled device.

2015/12/23 | 555 | 2,134 | <issue_start>username_0: I'm trying to connect my 2014 Macbook pro to a Pixel C tablet. The tablet has developer settings enabled, usb debugging enabled and unknown sources enabled. 'adb devices' shows nothing and there is no debug icon shown on the tablet.
I'm using a usb 3 type C connector that works **Perfectly** from my Macbook to my Nexus 5x
I've tried resetting the PRAM/NVRAM and the SMC to no avail.
The strangest thing is that we have 3 developers here with 2 ports per macbook. It *does* work on ONLY 1 port on one macbook, a 2015. We have a second *exact* same macbook bought on the same day that this tablet doesn't work on either.
Since it works on 1 port on one macbook, we know that the tablet is configured correctly for debugging. But why can't we connect it to the second port on the same machine or to another macbook??
We've never had any issues connecting any other Android device to any of these macbooks before.
**Updates:**
1. Got a different usb C cable and still have same issue.
2. Default USB Configuration (from Dev Options) is MTP, tried other USB config PTP and didn't help
3. After testing again on the 1 port that it worked in the past, trying 'adb devices' shows the Pixel C about 3 out of 5 times (in the span of 10 seconds). Trying to deploy to the device fails every time, presumably due to the flakey connection...<issue_comment>username_1: I have tried a number of USB 3.0 cables with no luck but every high quality USB 2.0 cable I've tried has worked for me. This includes USB 2.0 cables that have a Type C connector (There are many of these on Amazon. I'm currently using an "iOrange" brand cord) as well as traditional micro-usb cables with a Type C adapter ("TechMatte USB-C to Micro USB Adapter").
I'd prefer faster charging and better speeds but this takes care of my debugging needs reliably.

Or alternatively, can I view their chat history remotely?<issue_comment>username_1: Find out where they have backed up their data, on the cloud or in their sd cards, then you'll have to retrieve the data and you are good to go.
Upvotes: -1 <issue_comment>username_2: This is not possible without breaking the law. Whats app uses a store and forward mechisnism, that means the messages are stored on the server then forwarded on to the client (i.e the persons phone you are talking to).
The only way to get access to the data on their phone or the whatsapp server is with a court order.
You will be able to see any conversation you have had with them on whatapps, but nothing more.

I checked the path `/data/misc/wifi/` using `adb pull` from terminal, but it's empty<issue_comment>username_1: You can't get the passwords without root access because shell (adb) is not privileged to access the file containing those passwords. As you would know, the file `wpa_supplicant.conf` contains all the saved Wi-Fi passwords. In order to even ascertain the existence of that file, you must have read or executable permission until `wifi` directory. It just happened that the permissions on that directory is `drwxrwx---`, is owned by user `wifi` and group `wifi`. Executing `id` tells us that shell is not part of `wifi` group, so it ultimately would be considered `others`. As you can see, the permissions for others are blank `---` i.e. no read/write/execute permission is available, hence, you can't enter that directory, let alone copy a particular file residing inside it.
Root the device if you want that file badly.

Upvotes: -1 <issue_comment>username_4: I have to say I am surprised that the answer to this is hidden so well on the internet.
**It is a myth that retrieving the WiFi passwords from an unrooted device is impossible.**
Prerequisites:
* developer mode activated on android device
* USB debugging (in activated developer options)
* USB data cable
* adb (on host computer)
* java (on host computer)
* an archiver such as winzip or 7zip (can be skipped on Unix systems)
These prerequisites may differ depending on operating system. android version and manufacturer. Answers on how to prepare these on your specific platform can be easily obtained with a search on your favourite search engine. Keep in mind that a USB cable that is good for charging your phone not necessarily provides a data connection. Use the cable that came with your phone if in doubt.
Steps:
1. Connect your phone to the host computer using the USB data cable
2. Backup your WiFi passwords with *adb* (from command line).
```
adb backup com.android.providers.settings
```
3. Enter a password for the file on your phone. The resulting file will be named "backup.ab" and appear in the directory where you executed *adb*.
4. Download and install [Android Backup Extractor](https://sourceforge.net/projects/adbextractor/).
5. Convert the backup file into a TAR archive using the password that you entered earlier:
```
java -jar abe.jar unpack backup.ab backup.tar *password*
```
6. The archive will contain a file called "flattened-data". This file contains all networks that are saved on your phone. The *psk* entries are the passwords.
Notes:
It may be easier to move the backup file into the same directory as abe.jar before converting it.
Tested on Android 7 and Ubuntu, adb version 1.0.36, android-backup-extractor v20180521. If *adb* doesn't work, make sure you device is found using `adb devices`. On the same device, I tried to access the passwords directly using `adb pull` which didn't work (as was expected).

2015/12/24 | 584 | 1,803 | <issue_start>username_0: I want to change the recovery image from ODIN package for Samsung P601. I've unpacked the archive and got recovery.img.
Next I've tried to do `simg2img recovery.img recovery.raw.img`, but it says:
>
> Invalid sparse file format at header magi Failed to read sparse file

I think that means that it should not be converted.
I've tried to mount it, but the FS seems to be not ext4.
So, the question is - how to mount recovery.img, change files there and save it back? I'm using OS X and Windows (with cygwin).<issue_comment>username_1: Recovery isn't a sparse image (which is an Ext4) so you cannot do that, neither mount it. It's a boot image for which you can use mkbootimg.
Upvotes: 0 <issue_comment>username_2: You can use `unmkbootimg` from [this thread on XDA Developers](http://forum.xda-developers.com/showthread.php?t=1877807).
```
$ unmkbootimg recovery.img
```
This should give you two files: `initramfs.cpio.gz` and `zImage` (the kernel image). To extract `initramfs.cpio.gz` use this command:
```
$ mkdir ramdisk && cd ramdisk
$ gunzip -c ../initramfs.cpio.gz | cpio -i
```
Check [this post](http://www.imajeenyus.com/computer/20130301_android_tablet/android/unpack_repack_recovery_image.html) for more detailed information.
EDIT:
I just realized I only answered half of the question. To re-pack the image after making changes to the extracted files, use the command that `unmkbookimg` gave you, e.g.
```
mkbootimg --kernel zImage --ramdisk initramfs.cpio.gz --base 0x40000000 --cmdline 'console=ttyS0,115200 rw init=/init loglevel=8' -o new_boot.img
```
According to the article, use this command to create the new initramfs.cpio.gz file (untested):
```
find . | cpio -o -H newc | gzip > ../newramdisk.cpio.gz
```

2015/12/24 | 1,296 | 5,146 | <issue_start>username_0: Just got a Fossil Q Founder smartwatch. Currently, it is showing Fahrenheit. How do I change the default weather app to use Celsius?
I've changed literally every single setting I can think of. I have used the Fossil app to change the watch faces to show the temperature in Celsius. I have Google Now cards configured to show in Celsius. I even tried downloading the Google News and Weather app and changing the temperature units used there. I checked every settings menu I could find in both the Android Wear app and the Fossil app. Nothing.
Rocking a Nexus 6P. Everything is the latest.
Multiple Google search results have pointed to Google Now weather card settings as the place to change the units in the Android Wear app, but as I mentioned above, I already have those set since before I even had the watch. I tried changing to Fahrenheit and back to Celsius, but still no luck. I've tried restarting the watch and my phone a million times, but also had no luck getting the settings to take on my watch.
Can someone please help? It doesn't help that Google has the worst support imaginable. I would bet my life savings that if I called them for support, they would tell me to do a factory reset without even attempting to understand that actual issue.<issue_comment>username_1: I contacted Fossil who said that the temperature units on the watch are based on the language setting you select when you set up the watch. If you select US English, then it will be Fahrenheit (probably the only language setting that uses Fahrenheit).
I am Canadian and there is not usually a Canadian English option, and UK English has caused strange anomalies for me in the past. Plus I live in the USA, I just want Celsius and I don't think I'm the only one. I informed them that their solution for units is not adequate.
I am using the AccuWeather app which I paid for years ago and I like it. But their Android Wear app is broken right now on my watch and they are aware of the issue and working on it, but it has been some time (plus their latest material design update took ALL of their flexibility out of unit selection so that is quickly becoming an issue).
Upvotes: 4 [selected_answer]<issue_comment>username_2: It's because your phone language is set to US English.
Just change your handphone language to another type of English, such as English (United Kingdom), then the weather on your watch will change to Celsius.
Upvotes: 2 <issue_comment>username_3: I just bought a Fossil Q Founder watch.
If you go to watch setting, then change watch face, scroll to classic, tap the setting bar below the displayed face, then it will allow you to scroll down to weather unit. Tap it and it will allow you to change between Celsius and Fahrenheit.

2. Go to <https://myaccount.google.com/u/1/language>
3. Change your language preference default to English and then choose Canada.
4. Make sure you use the same account for Google Wear OS.
5. If you are using the same account, after this change, restart your Fossil watch and you should be good to go.
I have tested this on Fossil Gen 5 and it works.

I found a solution though. I updated my language setting on my phone through Settings, System, Languages and inputs, Languages. I had English (United States) as my default language and English (Canada) as my second language. I deleted English (United States) and that changed English (Canada) to my default. Once I did that, my phone immediately updated with Celsius.
Reference: [Wareable - How to change the language on Wear OS](https://www.wareable.com/android-wear/how-to-change-the-language-on-wear-os-6991#:%7E:text=Changing%20language&text=the%20only%20way%20to,Languages%20%26%20input%2C%20then%20Languages.)

On the phone paired to the watch, go to `Settings -> System -> Languages & Input -> Languages`.
There you will be able to set English as your preferred language, and in a second step whatever country you prefer to derive units and regional typing conventions from (date format, decimal point/comma, etc), no matter wether english is actually spoken in that country officially.

2015/12/25 | 755 | 2,914 | <issue_start>username_0: My Nexus 5 is rooted. I received the 6.0.1 OTA update but when I try to install the update (I just clicked install link when the update finished downloading), the device restarts and goes to the [TWRP](https://en.wikipedia.org/wiki/File:TWRP_2.7.0.0.png) screen and doesn't install the update.
Can anyone tell me how I can get the update to install?<issue_comment>username_1: You cannot install an OTA update on rooted device because SuperSU changes some statement in install-recovery.sh to run itself on boot.
To install OTA you need to install factory image available at <https://developers.google.com/android/nexus/images?hl=en>
If you dont want to loose your apps and data. Simply edit the script **flash-all.bat** and remove
```
-w
```
From
```
fastboot -w update image-hammerhead-*.zip
```
Installation script file name will differ according to your OS.
You will loose root access and TWRP after going through above method as there's no other way to install OTA because all system files should be intact for successful installation of OTA.
Upvotes: 3 [selected_answer]<issue_comment>username_2: If your phone is rooted by flashing normal SuperSu, then the SuperSu app and binaries would have been pushed into the /system partition of your phone. OTAs normally verify the checksum of your current system partition with that of untouched stock system partition's before the update. By rooting your device, which modifies the system, the MD5 sum would definitely not match, so you won't be able to install the OTA.
If you had rooted it by using systemless root (by SuperSu), then you can flash the OTA with no issues, since system partition will not be modified by that method. It seems you have TWRP installed now. It is better to flash the [stock ROM (6.0)](https://developers.google.com/android/nexus/images?hl=en) and don't root it. Then install the (6.0.1) OTA through the stock recovery.
There's no way other than this.
Upvotes: 1 <issue_comment>username_3: You can using app: [root] FlashFire that can downloaded in PlayStore.
Then, download the latest factory images package for Nexus 5 from [here](https://developers.google.com/android/nexus/images)
After the file is downloaded and saved in your phone, open FlashFire app.
The app will grant root access and if it found update[OTA] file, choose 'delete'.
Next, click "plus" icon > choose "Flash firmware package" > browse to the location that you saved the downloaded factory image.
Then the app will scanning the firmware file and after that you can select some options.
\*If you want to keep TWRP as recovery, just uncheck "Recovery".
\*Be careful, if you want to keep your data in phone, make sure that "Data" unchecked.
Last, just click "FLASH" then your phone will reboot and install the update.
\*Note: I've tried this for my Nexus 5 and it is successfull. Hope it works for you too :)

But I now have a new problem. This game I was playing for months on this phone, says it is not compatible with my phone. I still have the files of the game in my SDcard but app isn't there. I tried to update my phone but it says it is already up-to-date (4.2.2) What should I do?<issue_comment>username_1: Simply find .apk file of that game on google, and then install it.
Upvotes: 2 <issue_comment>username_2: I have had this issue before. It means that you can not play the game in question due to incompatibles like if your device does not support multi-touch and the feature is then recommended for use in the game. If you have another device that you can play this on you can extract the app (50 / 50 chance). Some apps can be extracted others can not. You will in turn have to allow **Unknown Sources**(Risky for leaving on when done and otherwise) when you are to reinstall it. I have done this with a game, to play on a Samsung Galaxy Tab 4 that said "this device is not supported". You'll need to download an APK extractor first (APK: Android PacKage)
**WARNING: Sharing Applications Purchased by you (Free and or otherwise) is against Google Play's terms and conditions and or is in a grey area. Selling the app as your own WILL put your Google account under review for possible ban and or removal**
* Grey area
-Open Source Hardware (**Recommend to ask Developer** Developer will recommend you to direct him/her to the app on his/her device and install)
After installing the APK extractor do as follows
* find the app in question
* extract
* locate APK
* Save to SD card and place into device of choosing
* go to settings on device in question
* go to Security
* Allow Unknown Sources (**Read Warning and continue at own risk**)
* goto folder with game in question
* click the APK and install

So, I recently upgraded from Nexus 4 to 5x. My contacts used to live on the sim, but since having to change sim (micro -> nano). I exported the contacts using the Contacts app to a .vcf file. I have now imported these contacts to my Gmail account via web.
On my Nexus 5x (6.0.1 update), I cannot see how I can sync contacts from Gmail. I have an issue where I cannot edit **some** contacts if I just import straight from the vcf file. I am logged in to my Gmail account.
This should be a simple task and I cannot figure it out.<issue_comment>username_1: Figured it. I was browsing the Apps list and I had Google Contacts Sync app disabled, thinking I wouldn't use it. The edit pencil icon is now visible.

I have tried installing it manually but it just can't work and crashes every time I want to download or update apps.

You can choose from a variety of packages, available on multiple versions of Android. See [here](http://forum.xda-developers.com/android/software/tk-gapps-t3116347) for more information.

To convert, you can simply use ES File Explorer. With this option, first, uninstall the Play Store. Enable root explorer in the app dashboard. Still, in the dashboard, tap local and select device. Look for system, app, and there paste the Play Store APK file there that you have copied (so you first copy the Play Store APK before going to root explorer). Next reboot.
Or you can convert to a system app using any root app like Link2SD. Here you need to install the Play Store app, next you open Link2SD and select Play Store. Tap the more options button and tap convert to system app. After it is complete, reboot.

2. Delete files from Lucky Patcher folder
3. Click on Tools
4. Click on Install Modded Play Store
5. Click on original, not on modded; this process takes time of 5 minutes.
Now you have your own Play Store.
Upvotes: 0 <issue_comment>username_4: The "Install Modded Play Store" dialog in Lucky Patcher also supports installing the unmodded Google Play store. To do this, open Lucky Patcher > Tools > Install modded Play Store > Original Play Store (select version). Make sure to uncheck "Install as a User App" before installing. Then reboot.
If it doesn't install right (or doesn't appear after reboot), you could try it manually. Go to Rebuild & Install > LuckyPatcher > Download, select PlayStore.apk (which was downloaded by installing the unmodded Play Store above), press "Install as a System App", and then reboot.

If that's the case, then there's really nothing that can be done from the user's side except by letting their operator know and request to allow/register the short numbers. Otherwise, switching to a different operator is the last alternative.

2015/12/25 | 1,154 | 3,982 | <issue_start>username_0: We're using Samsung with Android 4.1.2 as a scrabble timer - via the default Clock application. It would be much more comfortable if I could force the phone screen to be always on so that we can see the time remaining. I found no setting or downloadable program to achieve that.
I need some workaround tip - any ideas?<issue_comment>username_1: You should be able to do that using [Tasker](http://www.appbrain.com/app/tasker/net.dinglisch.android.taskerm). Set up a profile with a "time" condition (specify the time frame you want the screen kept alive, e.g. "from 9 am to 6 pm", and for the task itself select "stay on". Make sure the option is disabled before starting this. [tasker](/questions/tagged/tasker "show questions tagged 'tasker'") will then take care for it: Switching the option on at 9 am, and returning to the *previous state* at 6 pm (which is why you should have switched that option off to begin with).
Optionally, you could also define an "exit task" to explicilty switch that option off again − regardless of what it was set to in the beginning.

So, that's why you need [an extra software for Mac](https://www.android.com/filetransfer/), because Apple only wants its devices to be supported.
To avoid that, you could try to mount your SD Card in USB Mass Storage (UMS) Mode.
That could be easily be done from Settings if you're using Android JellyBean or below.
For KitKat (4.4) and above, you need to have a rooted device & some other external apps like **[Universal MASS STORAGE Enabler](http://forum.xda-developers.com/android/apps-games/app-universal-mass-storage-enabler-beta-t3240097)** (created by me) or [USBSharer](https://play.google.com/store/apps/details?id=os.devwom.usbsharer&hl=en) or whatever.

2015/12/26 | 587 | 2,324 | <issue_start>username_0: This is dangerously close to "recommend me an app" although it is not necessarily so.
I am currently doing a lot of reading on an online library site. Usually my browser (chrome, android 4.4.2) will go to a "full screen" mode when I scroll down a page of sufficient size. But such is not the case here, and that site is not unique in this sense either. The how and why of this is irrelevent to me, I just want to be able to read with the nav bar hidden.
Unfortunately, with the trendy "easier to use" (i.e., dumbed down) interface AFAICT you cannot force this behavior. Last time I used firefox it had tabs in a manually hidable sidebar, so I installed that. But it now looks and behaves just like chrome :( As an irony, it seems that firefox's own homepage is an example of one which will not invoke fullscreen when scrolling down.
I am aware of "immersive mode" apps but have not tried this because I presume it will then just hide the system notification bar and I will get a slightly bigger view of the browser with tabs along the top. However, if I'm wrong please correct me.
Does anyone know of a way out of this, including a browser which still includes a manual fullscreen mode (as silly and archiac as it may sound)?<issue_comment>username_1: Sadly Google Chrome and other browsers don't have a feature to hide the url bar and tab bar.

2015/12/26 | 685 | 2,782 | <issue_start>username_0: I'm the owner of a Huawei P8. At the beginning the phone was recognized by my PC as a second hard disk but lately I touched something (I don't remember what).
Now, when connected to the PC, the phone is set to charge but it is not seen as a mass storage and neither the computer nor the phone seem to recognize each other. I went through almost all the settings but couldn't find ANYTHING on how to make the computer react to the phone.
USB debugging cannot be used. I would like NOT to have to root the phone or do strange installations – and online the only kind of answer I found was that I have to do a hard reset of the phone. Is it true? Can anybody give me a less traumatic suggestion?<issue_comment>username_1: I have the same problem. Phone is wonderful except for this annoying bug, and I've spent hours searching for a solution: None.
You need to do a hard reset for the phone give you the dialogue where you choose usb connection mode. Oh, and don't choose "nothing" (ever), cuz then you'll have to this over again.
REMEMBER to back up everything on internal memory to your SD-card and remove the SD-card before resetting, or it's content will be deleted! I really wish for a better solution than this, but its the only way for now.

The problem was not with the cable or PC - the same cable and PC would work later on, with the only changes made, made to the phone.
I didn't have the same qualms about rooting or 'strange installations', so I rooted using KingRoot then used "SG USB Mass Storage Enabler" on the Play store to toggle the storage mode.
This worked for me, even though SG Mass Storage Enabler is made for Samsung and Sony devices, and hasn't been updated since 14 Nov 2013.
A disadvantage of this method was being unable to uninstall KingRoot. This may be my own fault though, possibly due to me corrupting the KingRoot install by trying to replace it with SuperSU.
This method was the only method I tried that worked. Things that didn't work included trying to backup without root to factory reset (this is data and application dependent on whether you can backup without root), trying to activate USB debugging, ADB, Hisuite and HDB.
If a custom recovery is already present on the phone, then SuperSU could be used to root instead of KingRoot, which is adware at the least, and also seems to prevent itself being removed from outside the app.

The problem is that my phone's battery is low, and I have no way to charge it in another phone. Can I put the phone into download mode and charge the battery? Will that work?<issue_comment>username_1: Yes, it works without any doubt. I can say it by my on experience. It happens like your phone is switch off. Here, you can watch it's animation of charging if except this ( low battery ) everything OK.
Upvotes: 0 <issue_comment>username_2: It will charge, but you may not have "charge full" indication , so monitor charging so that you don't end up charging once it is full ( batteries do not charge once full but internal temperature goes up, which is not good for battery life). Charging for 90 minutes should comfortably see you through flashing activities

2015/12/27 | 671 | 2,302 | <issue_start>username_0: Apologies if this question was already asked.
Is it possible to move the `/data` directory to the external SD card?
I want all apps, app data, downloads and files to be automatically saved to the external SD card, instead of to the internal storage.
**Information:**
The internal storage is 178 MB, where 157 MB is used by apps. There's no internal SD card and my external SD card has 32 GB.
`/sdcard` is a symbolic link to `/storage/sdcard0` which is the 32 GB external SD card.
The device is rooted and uses CM11/4.4.2.
**Tried:**
1. Used `Link2SD` but could only move the APKs and dalvik. The app data and system apps couldn't be moved. Unfortunately I can't buy the new Link2SD.
2. Tried `FolderMount` but it doesn't allow access to `/`. It only allows access to the SD card.
3. Couldn't find fstab in `/etc` or `/system/etc`
4. Tried `Root External 2 Internal SD` but there's no internal SD card, just "internal storage" (shows 178 MB) and "SD card" (shows the 14 GB FAT32 partition on the external 32 GB SD card).
**Considered:**
```
su -
cp -r(p?) /data /storage/sdcard0/data
rm -r /data
ls -s /data /storage/sdcard0/data
```
However, I'm new to modifying Android and don't want to accidentally brick my device. When I tried to copy the data directory as root, it said that some files/directories did not exist.
Does anyone have suggestions?
Thank you for reading.
Edit: @programming Thanks for your help. I can't find the option on the storage page.
The storage page looks like:
```
Storage (clicking on `:` gives the option "USB computer connection")
Internal storage:
Total space ...
SD card:
Total space: ...
Erase SD card
```
There are no additonal options, as in: <http://teckfront.com/use-external-sd-card-primary-storage-android-4-4-3-phone/>

It was working fine, I even restarted it a few times just to test everything was going nice and dandy. I also installed two apps to see if SuperUser was working properly (busybox and titaniumBackup) and both seemed to work fine.
Now, while trying to make a nandroid backup I entered recovery mode and touched "reboot device now". Afterwords, the device stopped starting properly.
As described in the title, the screen remains black with messages popping up saying something like "[x] app has stopped working". Trying to turn off the device gives me the usual windows (turn off/airplane mode/restart). Also, I can change the volume. Any idea of what could be going on?<issue_comment>username_1: If you want to set your SD card as the default storage device, go to `settings > storage`, then select **default writing disk** to SD card.

Definitely NO, `/sdcard` is not backed up, because of there would be a CWM backup. Read: <http://forum.xda-developers.com/galaxy-s3/help/how-to-backup-internal-sdcard-t1999853>
Hope it help
Upvotes: 4 [selected_answer]<issue_comment>username_2: To add to other answer, your back up has ALL the information in your back up image as the phone has when you took back up
* `/system` refers to your ROM
* `/data` refers to your data created by apps both that came with phone and user installed apps (`/data/data`)
* `/data/cache` (the cache) refers to app data stored for quick access
* `/data/dalvik-cache` (the Dalvik cache) refers to storage where optimisation information of your apps is stored
* `/sd-ext` refers to external SD card (all CWMs do not by default save this)
Other partitions mentioned are not backed up. Compression happens if you enable it (IMO, not worth the extra time it takes, given you can always store it in external SD (by choosing it) or pull it to your PC)

Boot into CWM/TWRP Bootmenu (pressing "Volume up" Key and Power Button) while starting the phone - and chose to clear "Dalvic Cache and Cache". Both will have **no** impact on your installed software or data. So it is quite safe to do.
After clearing reboot. The next restart will take a bit longer because these caches have to be rebuilt again. Solved my problem with random shutdowns.
Another possibility could be a dead battery. Especially if charging values change between full loading (100%) and after rebooting (90% or similar) ...

2015/12/27 | 869 | 2,934 | <issue_start>username_0: I'm new to Android and trying to find the simplest way to run a 2 line script that deletes files from a specific directory.
I Googled the topic and created a file that I called `test.sh` which has 2 lines:
```
#!/system/bin/sh
delete Android/data/mydir/*.dmp
```
I copied this file to an Android device and managed to create a shortcut to this file. Now I want to execute this script whenever I click the shortcut but I'm unable to make it work!
I would appreciate any hints to get this going.
Thanks!<issue_comment>username_1: You can use [Script options](https://i.stack.imgur.com/CCiFx.jpg)
Has more privileges if you have a rooted phone
You can choose the script via the inbuilt file manager, and can choose various options, as seen
And yes there's no command as delete Use
>
> rm -rf
>
>
>
instead as suggested [above](https://android.stackexchange.com/a/132741/132780)
Also if you are trying to delete the data created by an app i.e inside **data/data/example.app/DataToDelete**
You will need to have Superuser privileges or only that particular app can delete its own data.
Upvotes: -1 <issue_comment>username_2: In your script you forgot `#` , and what is more the command to **delete** is not `delete`(as you wrote) but `rm`, along with at least one option:
* `-r` for recursive
* `-f` for force
* `-v` for verbose
so try
**For a single file**
```
#!/system/bin/sh
rm /path/to/file/filename.extension
```
**For a group of files @ location by extension with wildcard:**
```
#!/system/bin/sh
rm /path/to/file/*.extension
```
**A straight up clearing of a directory:**
```
#!/system/bin/sh
rm /path/to/directory-containing-files/*
```
Alternate to **clear that directory of files and directories as well**, with verbose to see what's being deleted
```
#!/system/bin/sh
rm -frv /path/to/file/*
```
**To delete the directory itself**
```
#!/system/bin/sh
rm -fr /kill/that/pesky/directory
```
You must have `root` privileges to modify anything in `/system` and/or `/data` folder.
The exception would be `/data/local` directory which you should be able to access/modify within as peon user.
If `selinux` is enforcing **you will NOT be able to modify anything** in `/data` with the exception of the previously stated exception even if `su`.
This with the exception of laying out the proper path to `sh` in your script is not really an android question.
**Your normal practices in scripting on a Linux OS should mostly carry over as long as you use the correct path to `sh`.**
You can create that script in regular `sdcard` storage space and execute by running
```
su
/sdcard/./yams.sh
I like yams. They're nummy.
```
**If you get a permission error, denied etc.,** then
```
chmod 755 /path/to/script.sh
```
and again run as `su`
**You can alternately run**
```
su -c /sdcard/yams.sh
```

2015/12/27 | 538 | 2,010 | <issue_start>username_0: I am trying to download a game for my child in the Amazon Underground app store.
The problem is, the Underground app refuses to install under my child's login (it claims to be incompatible with my device!?!). I can install both the Underground app and the particular app I want to install under *my* login, but I don't allow my child to know my PIN or use my login as I have other things install I don't want her to mess with.
If I could find the APK before it is installed I figured I could just manually install it under my child's login, but I can't find it! I have run a file manager and did a search under the entire filesystem (as root, no less!) for all files within the last hour, and did not find *any* APKs. Some other answers [here](https://android.stackexchange.com/questions/18989/where-are-the-downloads-from-the-amazon-appstore-stored) and [here](https://android.stackexchange.com/questions/10336/amazon-app-store-location-of-the-downloaded-apk) claim it is stored in `/sdcard/Android/data/com.amazon.venezia/cache/` or `/sdcard/Android/data/com.amazon.venezia/files/apks`. However, both of those directories are empty after the download is finished. I am looking when it tells me the download is ready to install, but before I allow it to install, so I know the APK must be around there somewhere. Where is it?<issue_comment>username_1: Look in `/data/data/com.amazon.mShop.android/files`
I had to use Fx to search my entire device to find the Amazon Video APK.
Upvotes: 1 <issue_comment>username_2: The smaller size apps are located in `/data/data/uk.amazon.mShop.android/files/` and are named `update.......` - you must be root to see/extract these.
The larger size apps or games are located `/sdcard/apks/` as they are too big to store in the apps private /data/data directory and are also named `update....` - a stock user can see/extract these.
This was correct at time of posting as the location has changed i nthe past, it may well change again.

2015/12/28 | 1,118 | 4,525 | <issue_start>username_0: Chainfire (the developer of SuperSU), has come up with a new style of rooting devices on Android 6.0 Marshmallow and above. This is "**systemless**" root, and is all the rage right now. So, just in case anyone feels curious, I thought there should be some information about "systemless" root here for future reference.
**The main question:**
What is "**systemless**" root, exactly?
This question has 2 ancillary questions, which are:
1. Where is it more applicable over traditional "**system-based**" root, and how is it different from it?
2. Is it better than traditional root? If so, how?
A comprehensive answer to the main question along with the ancillary questions will be preferred.<issue_comment>username_1: Systemless root, developed mainly by Chainfire, is an alternate method to root your phone without altering files in your system. It makes changes in the boot image instead of the system files like init, etc, and hence makes rooting and unrooting theoretically easier. It is an experiment, so I don't think it works perfectly. It also could circumvent Android Pay root restrictions, but Chainfire did not expect that, and says that Android Pay would be patched to push out any such root users too.
For more information about it, check the [xda](http://www.xda-developers.com/chainfire-releases-root-for-android-6-0-without-modifying-system/) article. The dev also has a forum [here](http://forum.xda-developers.com/showpost.php?p=63197935&postcount=2).
Upvotes: 3 <issue_comment>username_2: **Main Answer:**
Systemless root is a rooting method/procedure developed by Chainfire (the developer of the popular root management app SuperSU) which involves a modified boot ramdisk image. The superuser `su` binary becomes a kernel inclusion instead of existing under `/system/xbin/`, like in normal system-based root.
**Ancillary Answers:**
1. *Preference of systemless root over traditional root:*
It was initially suggested by Chainfire to be useful for Nexus devices from Marshmallow onwards to prevent rooted users from having to reflash the entire stock system, boot and recovery partitions before undertaking even a minor OTA update, which has since become more important as Google has introduced the policy of pushing out monthly security updates through OTAs, and flashing the entire device every month is tedious at best.
Systemless root eliminates the heavyweight system partition from the flashing equation, allowing the devices with systemless root to be updated just after reflashing stock recovery and boot.
2. *Pros of systemless root over traditional root:*
* Utility when OTA updating devices as mentioned above.
* The modified boot image gets rid of the "Tampered" screen on Android bootup from Marshmallow onwards, if the device has a non-stock partition, most commonly recovery.
* No exploits required. Systemless SuperSU can technically be flashed as a boot image through fastboot, although it is normally done by flashing a zip in a custom recovery, which automatically patches the on-device boot image to make the necessary modifications to support systemless root.
* It works with an `SELinux Enforcing` security condition, while traditional root needs `SELinux Permissive` on Android 5.0 and up.
* It *unintentionally* circumvents Android Pay and Android for Work root restrictions, which work with traditional root.
3. *Cons of systemless root over traditional root:*
* Quite buggy and is still in BETA stage, although it is being actively developed and is definitely usable (from personal experience). **Edit:** No longer buggy and the default rooting method on Android 6.0.1 and up when using SuperSU.
* Some custom kernels like LeanKernel refuse to work with systemless root as they need traditional root for functioning properly. **Edit:** Most custom kernels now recommend systemless root, a well-known such kernel being ElementalX.
* Some root apps may not work with systemless root as they hard-code the `path-to-su` in their code, which is only applicable for traditional root.
* Not sure if this is actually a con, but systemless root is the only **recommended** rooting method that will work on Android 6.0.1 and up.

Upvotes: 0 <issue_comment>username_2: the reason is your haxm is not working is that, that your AVD and HAXM both must be configured to use same amount of memory(not sure if lower memory in avd will work).
you can change HAXM memory by reinstalling it(could not find any better method). during installation you will be asked to enter the desired amount of memory.
and you can change the avd memory from avd manager by clicking on the icon and then editing the avd by clicking the pencil button in the right, then go to advanced settings and you will see the memory option(might need to scroll on lower resolution screen)
Upvotes: 1 <issue_comment>username_3: Maybe you can try to use an emulator snapshot.To use a snapshot with your device, open the AVD manager from the Android Studio menu by selecting Tools→Android→AVD Manager, edit the AVD by clicking on the Edit symbol, then check the “Store a snapshot for faster startup” option.
This will save a snapshot of what the memory looks like when the device is running. The emulator will be able to restore the memory in this state without booting the device.
Besides, when you create a new virtual device, you can set its CPU type similar to your development machine(e.g. If your machine use a particular type of Intel x86 CPU, then set your virtual device's CPU to x86 architecture). Also, installing HAXM will help accelerate the speed. You can find it on <https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager>.
What's more, you can try to use GenyMotion instead of the original AVD.
Finally, running apps on your real device will offer you a more efficiency way to test the code.
In your case, it seems that your HAXM memory configuration(max 1024MB) cannot fullfill the AVD(1536MB) according to the screenshot. So you could adjust the HAXM max memory configuration by running the HAXM installer again. When the installer prompted to adjust the max memory size, set it to a number bigger than 1536MB, such as 2048MB. Then reload the AVD, the HAXM would run correctly, and the speed will improved efficiently.
Upvotes: 1 <issue_comment>username_4: Things you can try,
* Your AVD RAM size is higher than that of the HAXM's maximum RAM size. You can see in the log that,
```
emulator: AVD RAM size = 1536
emulator: HAXM max RAM size = 1024
emulator: You might want to adjust your AVD RAM size and/or HAXM configuration to run in fast virt mode.
```
So you need to adjust and set your virtual device's RAM lesser than that of max HAXM RAM size. I would suggest 512mb or 768mb for your AVD.
* The first startup can take a while, especially on a slow machine but otherwise try running the adb logcat command to see the log output. That will help you determine what the problem could be.
* Delete the emulator and create a new one
* Un-check the 'Snapshot' option and restart your emulator.

2015/12/28 | 1,658 | 6,482 | <issue_start>username_0: I have an old 64 GB sdcard and a new 128 GB sdcard, how do I copy over all files from my old card to my new in a way that makes android treat the new card just as the old card.
I tried simply copy-pasting over my DCIM folder, then I put the new sdcard in and rebooted my phone, on startup the phone recreated the /Android folder and all apps had rights to their new folders.
**Ways I tried to move the files:**
1)
* dd old card to disk
* dd to new card
+ after this the card works but is seen as having 64 GB instead of 128 GB
space
* use gparted to resize partition
+ this makes android see the card as having used 64 GB space but with no files or folders
2)
* dd old card to disk to disk
* dd to new card
* use fdisk resize partition
+ this makes android see the card as having only empty folders, but still used 64 GB space
3)
* create 128 GB partition
+ this I have tried with both FAT32 and exFAT
* mount via mtp
+ **Update:** I have also tried to copy paste all the files and folders directly to the sdcard from the old card via the cp comand on linux (that was the very first thing I tried... I only tried all the other things because this did not work)
* rsync all files and folders to the sdcard
+ this seems to make android see all the folders and files, but now my apps can't write to their own folders
+ eg
the problem in all of the above cases is that android eigher a) does not see the file, simply sees the card as a file with 64 GB used space but it cannot see any of the folders, or it does copy it over but the apps does not have 'access' to their own directories eg Android/data/com.bambuna.podcastaddict/files/podcast/ is where my podcasts are, but the app podcastaddict does not have write premissions for the folder.
so in short... how do I copy over all my files from the old sdcard to the new one... or do I have to factory reset my phone and redownload all my apps such that all the folders and appropriate premissions are created by android... which seems to be my only option
additional information
* my phone is a unrooted z5 compact
+ it runs android 5.1
* I have access to a Linux and windows computer, but would prefer Linux solutions.
* I don't care what file system is on my external SD card.
* I am familiar with the command line and would prefer solution listing a few commands I need to copy-paste
As Firelord suggested, rebooting the phone makes android "display" the DCIM folder, so this one can be copied over, however it still seems that the /Android/data/com.company.app/ folders have to be created by the apps themselves, otherwise they cannot write to them, but you can subsequently copy files into these folders
Factory reset and restore from backup did this for me... it is an ugly solution... but at least it works.
I erroneously assumed that file permissions werehidden somewhere on the SD card and therefore tried to find the 'correct way' to copy, but it seems that the folder permission is saved on the internal card, or they are tied to the application in some non-trival way.
I restarted my phone again, and then some of my apps lost permissions to write to their SD card folders?!?!, ie podcastaddict which had downloaded 300 podcasts overnight could not write to `sdcard1/Android/data/com.bambuna.podcastaddict/files/podcasts`
By deleting and reinstalling podcastadditc it regenerated its folder and it has been working since.<issue_comment>username_1: use genymotion emulator. It is fast comparing to general emulator. Program execution is fast than general emulator.

Besides, when you create a new virtual device, you can set its CPU type similar to your development machine(e.g. If your machine use a particular type of Intel x86 CPU, then set your virtual device's CPU to x86 architecture). Also, installing HAXM will help accelerate the speed. You can find it on <https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager>.
What's more, you can try to use GenyMotion instead of the original AVD.
Finally, running apps on your real device will offer you a more efficiency way to test the code.
In your case, it seems that your HAXM memory configuration(max 1024MB) cannot fullfill the AVD(1536MB) according to the screenshot. So you could adjust the HAXM max memory configuration by running the HAXM installer again. When the installer prompted to adjust the max memory size, set it to a number bigger than 1536MB, such as 2048MB. Then reload the AVD, the HAXM would run correctly, and the speed will improved efficiently.

* Your AVD RAM size is higher than that of the HAXM's maximum RAM size. You can see in the log that,
```
emulator: AVD RAM size = 1536
emulator: HAXM max RAM size = 1024
emulator: You might want to adjust your AVD RAM size and/or HAXM configuration to run in fast virt mode.
```
So you need to adjust and set your virtual device's RAM lesser than that of max HAXM RAM size. I would suggest 512mb or 768mb for your AVD.
* The first startup can take a while, especially on a slow machine but otherwise try running the adb logcat command to see the log output. That will help you determine what the problem could be.
* Delete the emulator and create a new one
* Un-check the 'Snapshot' option and restart your emulator.

There is 26 GB available storage on the device. I can copy a small file with no problems. I was able to copy a 4.9 GB file. The device is connected via USB and USB debugging is enabled.
What is the problem?<issue_comment>username_1: use genymotion emulator. It is fast comparing to general emulator. Program execution is fast than general emulator.

you can change HAXM memory by reinstalling it(could not find any better method). during installation you will be asked to enter the desired amount of memory.
and you can change the avd memory from avd manager by clicking on the icon and then editing the avd by clicking the pencil button in the right, then go to advanced settings and you will see the memory option(might need to scroll on lower resolution screen)

2015/12/29 | 1,095 | 4,054 | <issue_start>username_0: Can somebody help with how can I listen to text messages on my phone? One of my friend using this same feature now I want to know how it works. Is there any way I can listen to my texts?<issue_comment>username_1: The text-to-speech feature mentioned might not be app-specific (refer to @Izzy's [linked question](https://android.stackexchange.com/q/1146/16575 "Is there an app that will vocalize (text to speech) a message (SMS)?") for help on that). It probably is an Android system feature enabled.
The Android system feature mentioned is the accessibility setting of text-to-speech (or TTS for short). It is better referred to in-system as Talkback, and the app is automatically updated through Google Play as it is provided by Google. Your OEM may provide either Google TTS or Pico TTS, or both. Google TTS is of higher voice quality compared to Pico TTS.
As to enabling Talkback so that (every text you can touch on the screen, including) your SMSes can be read out by your phone (although that could be a security liability), I'll detail the standard method.
To turn on TalkBack, follow these steps:
1. Navigate to Settings → Accessibility.
2. Follow the steps for your version of Android. [Learn how to check your Android version](https://support.google.com/nexus/answer/4457705).
* Android 4.1 and above: Select TalkBack and slide the TalkBack switch to the on position.
* Android 4.0: Select TalkBack and slide the TalkBack switch to the on position.
Next, go back to the previous screen and turn on Explore by touch.
* Android 3.2 and earlier: Select the Accessibility checkbox, then select the TalkBack checkbox.
The confirmation screen displays a list of permissions that allow TalkBack to provide useful spoken feedback. To confirm that you allow these actions and to begin using TalkBack, touch OK.
Now, in your messages app, tap on the message and it will be read out to you.
**Note:**
TalkBack will read out anything you tap on-screen, as long as it has text associated with it. Beware!
For further details on Talkback, check out Google's official product support page for Android Accessibility [here](https://support.google.com/accessibility/android/answer/6283677?hl=en&ref_topic=3529932).
**READ THIS LAST:**
This is **not without** side effects. **TalkBack will read out everything on your screen you touch if it can be acted on or has text in it, including notifications.** Also, it will read out stuff like "colon p" for :p emoji and will read out all the characters in a web address. It will even tell you what you have touched, and let you act with a double-tap or move on to the next element without triggering anything.
Quoting from [this Android Central article](http://www.androidcentral.com/what-google-talk-back "AndroidCentral: What is Google TalkBack?") @Izzy mentioned:
>
> TalkBack isn't something you'll want to use unless you need it. Frankly, it's darn near impossible to use when you can see what it is telling you you're seeing, and you can't help but tap and try to do things before it is ready.
>
>
>
Now, TalkBack can be specifically enabled for just the messaging app(s) through usage of an automation app like Tasker or Macrodroid.
With credits to @Izzy, these should help you out with configuring Tasker for this purpose, as you need it:

there is no important/needed data on the phone
I tried factory reset, after used Dr Web to find viruses, and to root the phone (Kingo ROOT) in order to be able to remove some of them, 2 files identified by drweb couldn't be removed even though the phone was rooted because they were system files (priv-app/baseservice.apk and another one), I renamed them instead.
all this ^ didn't helped completely, they appear again somehow, so would like to format and clean install a new OS
**is there a easy way to do that ?**
my guess is I need some program on my pc (windows7) for this and connect the phone using usb and run some commands
the device is a fake galaxy S6, Android 5.0.2 kernel version 3.10.61<issue_comment>username_1: Things you can do:
1. Downgrade to your stock ROM and **install a good antivirus** and run a complete device scan because some of them are powerful enough to remove viruses from system files in priveledged user mode.
2. **Install Ubuntu Touch instead of android as shown in [this guide](http://www.pcadvisor.co.uk/how-to/linux/how-install-ubuntu-touch-image-3531970/)**. The guide is actually primarily for nexus devices but you can make it work for Galaxy S6 by finding the stock ROM yourself and other stuff for the S6 yourself instead of following the links given in the guide which are for nexus devices.

2015/12/29 | 781 | 2,886 | <issue_start>username_0: I have a Samsung Tab E that only has one USB port.
Can I charge the tablet and have a USB keyboard attached at the same time?
I've tried a 3-way cable ( [link to Amazon](http://www.amazon.co.uk/gp/product/B00EB70PQW?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s01) ) but it supplies power to the keyboard, not the tablet.
I've also tried using a USB hub I had lying around, but I couldn't get that to work either.<issue_comment>username_1: The most likely way to use a keyboard while charging on a single port device is to use a *Bluetooth* keyboard.
Failing that, you may need a different 3-way cable. The keyboard certainly needs power to operate (unless it has internal battery power), but a correctly wired 3-way cable should be able to *both* power the keyboard and charge the device. You can verify that there's voltage on the charge pins of the two USB connectors on the 3-way cable, with a meter and suitable fine probes -- though it's very possible that the device will refuse to accept charge if there's a data attachment on the USB port. You'd have to contact Samsung to verify that.

> In terms of actual current (milliamps or mA), there are three kinds of USB port dictated by the current specs: a standard downstream port, a charging downstream port, and a dedicated charging port. The first two can be found on your computer (and should be labeled as such), and the third kind applies to “dumb” wall chargers.

[Tablets are known to have any of these ports](https://android.stackexchange.com/questions/132832/device-uses-non-usb-charger-can-i-still-charge-it-through-the-usb-port/132872#comment166494_132872). The port you have for charging is a dedicated charging port (as I suspect ) and will not allow simultaneous data transfer. This is borne out by your observation that the keyboard is getting power when connected with a 3 way cable or even USB hub (more reliable for such requirements)
You can easily verify this by connecting a flash drive through an OTG cable and transfer files. If it doesn't work (as I suspect), you have your confirmed answer
It may turn out to be a futile attempt by introducing additional hardware to meet your goal if the port itself cannot support. You may like to first validate this by seeking a confirmation from OEM, in case my reasoning current appeal to you

* Stop
* Play videos in background
* Play videos in Piciture-in-picture mode
The issue for me was the power saving setting, similar to username_3's answer for their Huawei Mate 9.
Here's how to fix it on a Samsung:
* Open Settings
* Open Apps
* Find and open VLC
* Click "Battery"
* Toggle "Allow background activity" to on
Without this setting, audio playback will be stopped about 30 seconds after locking the phone regardless of the "Background/PiP mode". However, with "Allow background activity" turned on, audio playback will continue even with the "Background/PiP mode" set to "Stop".

I got the music onto my phone with my Chromebook, a HP 14, and simply moving the files to my phones "Music" folder. Once disconnected from my laptop, the music won't appear in the "Play Music" app. I know the files are on my phone, since they appear when I look in my file manager.
I've tried hitting the "refresh" button on both the music app and file manager, in addition to clearing the cache on both the applications. I've also rebooted my phone numerous times, and tried using a SD re-scanner with no avail.
This problem has happened on my phone before, and I solved it by clearing all the music data and putting it all back on my device. Still, I would really prefer not to do this, since it is kind of a pain.

2015/12/29 | 318 | 1,168 | <issue_start>username_0: I received OTA for my nexus 7 tablet few days back and since then my device is not booting up. Can someone please help how to get it working ?<issue_comment>username_1: Download the `Nexus Root Toolkit` from [here](http://www.wugfresh.com/nrt/). It has options to restore any Nexus device back to its factory settings, including bricked or boot looping devices, under the `Flash Stock + Unroot` button. You should select the option `Current status` of `Soft-Bricked / Bootloop`. The toolkit will walk you through, step by step, restoring your Nexus to working condition.
You may lose any data stored on the device.

1. Boot into stock recovery (guide [here](http://www.robschmuecker.com/how-to-boot-into-recovery-mode-nexus-7/ "Recovery Guide")) and wipe the cache partition then reboot.
2. If that fails, boot into recovery in the same way and wipe the data partition.
