2017/07/06 | 1,344 | 4,791 | <issue_start>username_0: I'm using a YubiKey Neo configured as an one-time-password generator. I'd like to use it with the [YubiClip](https://github.com/Yubico/yubiclip-android) app but every time I pass it next to my phone, Firefox (my default browser) opens with a blank tab.
Any idea how to make Firefox stop reacting to NFC events? I don't need NFC for anything else than Yubikey so it's okay if some other functionality is broken by doing this.<issue_comment>username_1: You can try restricting what the app can see with [XPrivacy](https://github.com/M66B/XPrivacy) if your Android version is supported (4.0.3 - 6.0.1).

I'm not sure specifically what you require, but you can try out [Parallel Space](https://play.google.com/store/apps/details?id=com.lbe.parallel.intl&hl=en), [Go Multiple](https://play.google.com/store/apps/details?id=com.jiubang.commerce.gomultiple&hl=en), [Multiple Accounts](https://play.google.com/store/apps/details?id=com.excelliance.multiaccounts&hl=en), or many others just like it available in the Play Store.
If you download any one of the launcher apps (such as [Nova Launcher](https://play.google.com/store/apps/details?id=com.teslacoilsw.launcher&hl=en) or [Google Now Launcher](https://play.google.com/store/apps/details?id=com.google.android.launcher&hl=en)) then after installing one of the parallel apps simply import the launcher app into the parallel app (it's the first thing you're asked to do upon opening any of the parallel apps) and you have a secondary "virtualized" environment to install most any app you'd like without it doing any damage to your phone or other apps/accounts/etc.

For example, Lenovo has incorporated a similar isolation mechanism in order to allow installation of multiple instances of applications or at least dual installation.
This feature is called *[Dual Apps](http://www.androidbeat.com/2017/01/how-to-use-dual-apps-lenovo-k6-power-note/)* in some Lenovo devices:
[](https://i.stack.imgur.com/w5XhOl.jpg)
The brief description states:
>
> Dual Apps will let you run two separate instances of the same app.
> Both instances will run independently of each other and will not share
> any kind of data with each other, except for contacts provided you
> have allowed that.
>
>
>
I believe this idea has been inspired with the recent surge of dual sim-powered smartphones and growing popularity of social networking applications such as WhatsApp, Facebook etc.
For this reason Huawei's EMUI 5.0 has implemented the same feature called *[App Twin](https://club.hihonor.com/in/tips.267/app-twin---an-exclusive-emui-5-0-feature.15269)*
[](https://i.stack.imgur.com/dUQQTl.png) [](https://i.stack.imgur.com/MkAw1.png)
Essentially for now it supports WhatsApp and Facebook but more applications can be added as suggested on [this XDA thread](https://www.xda-developers.com/how-to-clone-any-application-with-emuis-app-twin-feature-no-root/).
However it seems its not as fine-tuned as the former as it has some limitations :
>
> You cannot backup or clear App Twin account data separately. When you
> enable an app in App Twin and perform a backup, both the main account
> and twin account are backed up. When you clear app data, both accounts

Probably the most interesting project on this topic now is *[Island](https://forum.xda-developers.com/android/apps-games/closed-beta-test-incoming-companion-app-t3366295)*
The developer (<NAME>) is working on a beta version of this project, and is described
>
> *Island* is a sandbox environment to clone selected apps and isolate them from accessing your personal data outside the sandbox (including

> Isolated app can be frozen on demand, with launcher icon vanish and

The features are summarised as follows:
* app freezing,
* privacy protection,
* parallel accounts
As mentioned above its still in beta, and installation is via

Below is the image of boot lock screen when Mi Max is not connected to PC:
[](https://i.stack.imgur.com/6tmH3.jpg)

I was using my phone (Xiaomi Mi Max Dual SIM with 4GB RAM + 128GB ROM) and i got that screen. None of the buttons seams to dismiss the screen. Reboot always go to the same screen (boot loop). Can't use the phone (no calls, alarms, etc).
Below is the screen, when is connected to PC (the cable changes position in the image).

I download the pcsuite, mi flash and mi unlock on my pc but can't connect to device (even when i run the apps as administrator).
Below is Mi Pc Suite screen:

Below is the Mi Unlock screen (no device connected):

ps specs are:
* Dell OptiPlex 7020 CPU: Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz
* Dell Motherboard 0F5C5X with Intel PCH Q87
* Microsoft Windows 7 Professional (64-bit) Service Pack 1 (build 7601)
Have issues with "SM Bus Controller driver" that are now solved. I read in the foruns that Max is not yet supported by pc suite. pcsuite can't connect detect phone, but adb driver installed with success.
Mi Suite and Mi Unlock don't identify the device. Mi Flash detects the device if i boot with volume-down + power (and got a back screen). The flash failed on the initial tries, because the device don't reply to the hello package.
If i boot with power pressed for 8 sec (or more), i got into the phone + pcsuite lock screen and Mi Suite, Flash and Unlock don't detect it.
I try power up with volume up, volume down, volume up+down and no recovery screen (no rabbit or fast boot leters). Still can't use my Mi Max: no calls, no access to apps, nothing :(
The pc suit logs are at <https://drive.google.com/open?id=0B-J9Wa8DpsEzU0RTV3VMR0ZuRGs>
Does the Mi Flash util work without the unlock boot? I already got the sms unlock code, can login into my Mi account inside Mi unlock fine.
**New steps**
Reboot the phone using power + volume up + volume down (EDL mode - back screen)
Connect to PC, install the Qualcomm HS-USB QDLoader 9008 driver, Mi Flash detect the device and i could flash the helium\_global\_images\_V8.2.1.0.MBDMIDL (full flash, delete all).

I use a normal cable (no deep flash cable). I did the flash but **did not** open the case, remove the battery or short the testing points.
Below is the mi max test points photo (from tutorial on web).

When i reboot the phone (power button for 8 secounds) still get into the same "pcsuite.mi.com" and phone image screen. Mi Pc suite and Mi unlock don't identify my phone in 9008 / EDL mode.

Try this command `adb reboot bootloader` or `adb reboot recovery`
If any of the command works then you can flash stock image directly from bootloader using fastboot or from recovery.
[adb and fastboot commands for xiomi](http://en.miui.com/thread-24219-1-1.html)
If above mentioned method does not work then try this
As you have got unlock code, you can unlock bootloader now. (Typically after 1 week of requesting you can successfully do it).I guess you would be able to do it now so follow this method now.
After unlocking you can do either one of the following tasks
1. Flash a custom recovery (prefer TWRP) and then custom ROM
2. Download stock image for the device and flash it [link](http://en.miui.com/download-302.html)

2017/07/06 | 654 | 2,896 | <issue_start>username_0: I just bought a second hand phone (my first device running android). I'm surprised by the fact that three times I've been asked for permission to make and manage phone calls. This is a very scary thing to allow and it's even for things that don't seem to need it. I first noticed it when I wanted to run Diagnostics. It asks to Allow Support to make and manage phone calls. This is already strange but perhaps could be justified in the process of running diagnostics. But I tried some other things to check the permissions that they would ask and also the pre-installed Xperia File Transfer Mobile and even the FM radio ask for it. All of these are pre-installed and system apps.
Is this normal? Would you give these permissions? Or is there something wrong with the phone (malware?)?
(For now there is no sim in the phone so the damage that it can do is very limited.)

I already did a factory reset and the issue persists.<issue_comment>username_1: Does seem very scary given permission to almost all apps requirements to agree to many requests such as to all questions an apps wants from a person .Fear not it's normal in companies software automatically .The requirement consist of few or many wanting phone ,SMS,contacts ect: Give consent some apps won't let install otherwise why !!we don't know Go to settings click on apps go through as many as wishes turn off what you don't want a company app having to many of your personal details that's it (Done ) no need to reset your devices it's inconvenient and will need to back up your files ,folders ,contacts in the meanwhile in doing so may loose precious photo's and possibly some files .Just go to settings everytime you experience issues once you know how it's easy and less time consuming and save your sanity .

But in case you are feeling malicious activities you can deny them in settings freely as per you use. You can allow them once to use and deny after use. That simple.
Note: Just make sure your device doesn't giving notification/location/media permission to any third party app which doesn't have to do anything with these permissions.

2017/07/07 | 3,689 | 12,736 | <issue_start>username_0: I've recently bought a new Android smartphone. After setting it up and loading my contacts onto it I thought that would be it.
Now after some days, every time I unlock the phone it takes a few seconds before it opens the default browser and opens some spam website. I tried to see what was causing it. I removed any apps I didn't know I could trust, but the problem persisted. After trying to solve it for some time I gave up and reset the phone to factory default. Now after having it reset to the default it ran without issues for roughly a week before the problem reappeared.
I tried to uninstall some apps in order to see if they were to cause of it, but nothing changed after doing so. However I did notice that if I turn off the wifi it won't even try to open the browser (I haven't tried mobile data since I don't have a bundle). This makes me feel like it might be related to something on the network but that wouldn't explain why only that phone would have the issue when there are at least 6 android phones on that very same network.
I hope that there is someone who can help me find the cause of this issue and help me solve it.
TL;DR
When unlocking my phone, it opens the browser and tries to open a spam website. But only does so while connected to the wifi.
Things I've tried so far:
* Factory reset (only helped for a limited time)
* Clearing the browser cache and all related data
* Removing any app I don't know to be reliable
* Attempting to find what triggers it (seems like some type of internet connection is required??)
The device is the Doogee Shoot 1. As for the browser, the default is set to be the Android browser, but if I change the default it would use Chrome just as well. It seems to really just use the browser that is set to default.<issue_comment>username_1: Slightly more information needed to solve the issue, although I will attempt to find the possible problems. Which browser? What phone model? Was it purchased from official sources?
In theory factory reset should have helped you with the issue. Since it didn't, there are a couple more places where you can get some form of adware. First of all, you said uninstalling some apps? Which apps in particular? Did it appear after installing a particular piece of software?
Is it your wifi or are you using a public one? If its public one, usually companies send app install and advertisements requests through wifi relatively often. If you live in/near a busy area, wouldn't be surprised if that would be just someone using to advertise their product. Try using different wifi or someone else's wifi, see if the problem persists. If it doesn't. It is an issue with the network you are using, which means you are most likely going to need to change. You could try contacting your provider to help you with that (Had an issue like that before, my ISP providers helped me after contacting support). Also, see if the mobile network shows the same problem. If it doesn't, then your option would be to change the network you are currently using.
Upvotes: 0 <issue_comment>username_2: Based on the troubleshooting OP did following my advices, the culprit appeared to be a system app [as a malware](http://www.avgthreatlabs.com/en-ww/android-app-reports/app/com.tihomobi.lockframe.syslocker) named *System Locker*
with package name *com.tihomobi.lockframe.syslocker*. The issue appears to be a result of a system update, [per some users](https://www.google.co.in/search?q=%22com.tihomobi.lockframe.syslocker%22&oq=%22com.tihomobi.lockframe.syslocker) of the device.
As usual with a system app, if you get to use the **Disable** option under **Settings → Apps → System apps/All apps** → the culprit, than by all means, do disable that app, force-stop it or reboot the Android. The issue should stand resolved until you factory reset the device.

Troubleshooting #0
==================
Before you begin with a bit technical steps mentioned below, you would want to try a rather *user friendly solution* suggested [here](https://android.stackexchange.com/a/233762/96277). It that doesn't work for you, than come back and follow the rest of my answer.
---
Troubleshooting #1
==================
Here's how I found out the culprit. The in-built Android tool *dumpsys* inter alia shows which app was called by which other app. The caller is referred to as Calling Package.
Provided that you have setup [adb](/questions/tagged/adb "show questions tagged 'adb'") and [usb-debugging](/questions/tagged/usb-debugging "show questions tagged 'usb-debugging'") successfully in the PC and Android device, do the following:
1. keep the device connected to PC
2. reboot the device or force-stop that default browser app
3. let the malware do its job, that is, have the browser be launched automatically
4. as soon as the browser is launched, do nothing with the device physically, but run the following adb command on PC:
```
adb shell dumpsys activity activities
```
Here's the [output from OP's device](https://pastebin.com/z2g8TwJZ):
```
ACTIVITY MANAGER ACTIVITIES (dumpsys activity activities)
Display #0 (activities from top to bottom):
Stack #1:
Task id #2
* TaskRecord{8190ba1 #2 A=**android.task.browser** U=0 sz=1}
userId=0 effectiveUid=u0a64 mCallingUid=u0a26 *mCallingPackage*=**com.tihomobi.lockframe.syslocker**
affinity=android.task.browser
intent={act=android.intent.action.VIEW dat=http://im.apostback.com/click.php?c=362&key=<KEY>&s4=8%2FdNwcNuQFEjjaucho5IqA%3D%3D flg=0x10000000 pkg=com.android.browser cmp=com.android.browser/.BrowserActivity}

```
In the output: :
* *com.android.browser* is the package name of stock Android browser in your device
* *com.tihomobi.lockframe.syslocker* is the package name of the malware app and is referred as calling package.
If you've found the malware, avoid next troubleshooting and skip to the heading **Nuke the malware**.
---
Troubleshooting #2
==================
(In response to a duplicate posted [here](https://android.stackexchange.com/q/204334/96277) -- the culprit app was [Farming Simulator 18](https://play.google.com/store/apps/details?id=com.giantssoftware.fs18.google))
In certain circumstances, aforesaid troubleshooting may not be able to help, such as when calling package name is the package name of the browser itself shown in dumpsys output. In that case, prefer [logcat](/questions/tagged/logcat "show questions tagged 'logcat'"). Setup logcat like this:
```
adb logcat -v long,descriptive | grep "dat=http" # you can grep anything from URL too. It is purely up to you.
adb logcat -v long,descriptive > logcat.txt # alternative; if grep is not installed in your OS. You need to search into that file now.
```
Now unlock the device and let the browser with that URL be launched automatically. Also, press `Ctrl` with `C` if you are saving the output into a file.
The output we're seeking would look akin to:
```
[ 11-27 16:03:22.592 3499: 6536 I/ActivityManager ]
START u0 {act=android.intent.action.VIEW dat=https://livemobilesearch.com/... flg=0x10000000 pkg=org.mozilla.firefox cmp=org.mozilla.firefox/.App}
from **uid 10021**
...
[ 11-27 16:03:22.647 3499:15238 I/ActivityManager ]
START u0 {act=android.intent.action.VIEW dat=https://livemobilesearch.com/... pkg=org.mozilla.firefox cmp=org.mozilla.firefox/org.mozilla.gecko.BrowserApp}
from **uid 10331**
```
See the two highlighted UIDs 10021 and 10331. One of them (they would be different in you case) is for the browser app launched, and one of them is malware app requesting that URL. So, how to find what is what?
**If you've root access**, simply do:
```
adb shell su -c 'ls -l /data/data/ | grep u0_a**21**'
adb shell su -c 'ls -l /data/data/ | grep u0_a**331**'
```
Output would be like:
```
drwx------ 5 u0_a21 u0_a21 4096 2018-01-01 10:31 **com.android.chrome**
drwx------ 5 u0_a331 u0_a331 4096 2018-01-01 10:31 **com.tihomobi.lockframe.syslocker**
```
**If you don't have root access**, do:
```
adb shell dumpsys package > packages_dump.txt
```
Now search for the line with your UIDs such as "userId=10021" and "userId=10331". The line above the line searched would give you the package name, and may look something like this:
```
Package [**com.android.chrome**] (172ca1a):
userId=10021
...
Package [**com.tihomobi.lockframe.syslocker**] (172ca1a):
userId=10331
```
The two package names are com.android.chrome (for Chrome browser -- certainly not a malware) and *com.tihomobi.lockframe.syslocker*. To know the app's name from package name, use my answer [here](https://android.stackexchange.com/a/198095/96277).
---
Nuke the malware
================
Now that you know the culprit, you can disable it through GUI as stated above. If that is not possible, do:
```
adb shell pm disable-user PKG_NAME # disables the app
adb shell pm uninstall --user 0 PKG_NAME # removes the app for primary user
adb shell am force-stop PKG_NAME # only force-stops the app
```
Replace *PKG\_NAME* with package name of the malware you noted in the troubleshooting above.
That should do the trick. Furthermore, you can also consider removing the malware app permanently for all users, but that requires root access though.

The steps:
1. Connected my Galaxy Note 8 to PC, open CMD and took the logcat with basic command from withn CMD prompt:
>
> C:\Users\igorn> adb logcat > note8.1.log
>
>
>
2. As soon as the new tab with spam page was opened, I stopped the logcat capturing immediately by Ctrl-C and searched the log for "chrome":
>
> grep -i chrome note8.1.log
>
>
>
Last ten of found lines revealed the suspicious:
02-03 09:43:14.443 3931 4232 D GameManagerService: handleForegroundChange(). pkgName: **com.qrcodescanner.barcodescanner**, clsName: **kotovich.kotovich.kotovich.kotovich**.ScannerChromeActivity,FgActivityName:com.qrcodescanner.barcodescanner/kotovich.kotovich.kotovich.kotovich.ScannerChromeActivity,userID:0
3. Than I went to application list in device settings and saw the Barcode Scanner. Checked it on GoolePlay and found a plenty of 1-star reviews for exactly same malware behavior!
As well I noted that this application got last update two days ago, that match perfectly the timing - the problem started to appear exactly two days ago! Bingo!
4. Uninstalled it and the problem gone! Happy end :)
For infomation only: neither of other approaches like installing BitDefender, MalwareBytes, etc worked for me, so I was simply happy to sort it out!
So thank you, **username_2**!
Upvotes: 2 <issue_comment>username_4: So I was having this same issue and I kinda stumbled on a simple way to fix it.
First thing I did is I reset all the browser defaults so if ANY application wanted to open a browser it needed to ask me permission and then I can select which browser I wanted it to use.
Second I installed a browser I have never used... went into its settings and reset all its defaulted programs too so it couldnt just piggy back onto the new browser.
Then when it prompted me to select what browser that I wanted it to use I told it the new one I installed and told it to use that as default so it would put it in the browser.
I then went into the browser and found the only app that is set to use it as a default. It also showed me the last time it was used by that program and that time matched the time I told the spam thing to use the new browser as default.
In my case it turned out to be my QR code reader... I did notice its icon had changed a couple months ago. So it was either bought by a company that changed how it worked or the company was hacked and so it traveled down.
And as far as the browser goes I used the Samsung browser but I am sure the reset of them will have that last used part to make it easier for you to track down.
Hope this helps. :-)

with package name *com.tihomobi.lockframe.syslocker*. The issue appears to be a result of a system update, [per some users](https://www.google.co.in/search?q=%22com.tihomobi.lockframe.syslocker%22&oq=%22com.tihomobi.lockframe.syslocker) of the device.
As usual with a system app, if you get to use the **Disable** option under **Settings → Apps → System apps/All apps** → the culprit, than by all means, do disable that app, force-stop it or reboot the Android. The issue should stand resolved until you factory reset the device.

Troubleshooting #0
==================
Before you begin with a bit technical steps mentioned below, you would want to try a rather *user friendly solution* suggested [here](https://android.stackexchange.com/a/233762/96277). It that doesn't work for you, than come back and follow the rest of my answer.
---
Troubleshooting #1
==================
Here's how I found out the culprit. The in-built Android tool *dumpsys* inter alia shows which app was called by which other app. The caller is referred to as Calling Package.
Provided that you have setup [adb](/questions/tagged/adb "show questions tagged 'adb'") and [usb-debugging](/questions/tagged/usb-debugging "show questions tagged 'usb-debugging'") successfully in the PC and Android device, do the following:
1. keep the device connected to PC
2. reboot the device or force-stop that default browser app
3. let the malware do its job, that is, have the browser be launched automatically
4. as soon as the browser is launched, do nothing with the device physically, but run the following adb command on PC:
```
adb shell dumpsys activity activities
```
Here's the [output from OP's device](https://pastebin.com/z2g8TwJZ):
```
ACTIVITY MANAGER ACTIVITIES (dumpsys activity activities)
Display #0 (activities from top to bottom):
Stack #1:
Task id #2
* TaskRecord{8190ba1 #2 A=**android.task.browser** U=0 sz=1}

```
In the output: :
* *com.android.browser* is the package name of stock Android browser in your device
* *com.tihomobi.lockframe.syslocker* is the package name of the malware app and is referred as calling package.
If you've found the malware, avoid next troubleshooting and skip to the heading **Nuke the malware**.
---
Troubleshooting #2
==================
(In response to a duplicate posted [here](https://android.stackexchange.com/q/204334/96277) -- the culprit app was [Farming Simulator 18](https://play.google.com/store/apps/details?id=com.giantssoftware.fs18.google))
In certain circumstances, aforesaid troubleshooting may not be able to help, such as when calling package name is the package name of the browser itself shown in dumpsys output. In that case, prefer [logcat](/questions/tagged/logcat "show questions tagged 'logcat'"). Setup logcat like this:
```
adb logcat -v long,descriptive | grep "dat=http" # you can grep anything from URL too. It is purely up to you.
adb logcat -v long,descriptive > logcat.txt # alternative; if grep is not installed in your OS. You need to search into that file now.
```
Now unlock the device and let the browser with that URL be launched automatically. Also, press `Ctrl` with `C` if you are saving the output into a file.
The output we're seeking would look akin to:
```
[ 11-27 16:03:22.592 3499: 6536 I/ActivityManager ]
START u0 {act=android.intent.action.VIEW dat=https://livemobilesearch.com/... flg=0x10000000 pkg=org.mozilla.firefox cmp=org.mozilla.firefox/.App}
from **uid 10021**
...
[ 11-27 16:03:22.647 3499:15238 I/ActivityManager ]
START u0 {act=android.intent.action.VIEW dat=https://livemobilesearch.com/... pkg=org.mozilla.firefox cmp=org.mozilla.firefox/org.mozilla.gecko.BrowserApp}
from **uid 10331**
```
See the two highlighted UIDs 10021 and 10331. One of them (they would be different in you case) is for the browser app launched, and one of them is malware app requesting that URL. So, how to find what is what?
**If you've root access**, simply do:
```
adb shell su -c 'ls -l /data/data/ | grep u0_a**21**'
adb shell su -c 'ls -l /data/data/ | grep u0_a**331**'
```
Output would be like:
```
drwx------ 5 u0_a21 u0_a21 4096 2018-01-01 10:31 **com.android.chrome**
drwx------ 5 u0_a331 u0_a331 4096 2018-01-01 10:31 **com.tihomobi.lockframe.syslocker**
```
**If you don't have root access**, do:
```
adb shell dumpsys package > packages_dump.txt
```
Now search for the line with your UIDs such as "userId=10021" and "userId=10331". The line above the line searched would give you the package name, and may look something like this:
```
Package [**com.android.chrome**] (172ca1a):
userId=10021
...
Package [**com.tihomobi.lockframe.syslocker**] (172ca1a):
userId=10331
```
The two package names are com.android.chrome (for Chrome browser -- certainly not a malware) and *com.tihomobi.lockframe.syslocker*. To know the app's name from package name, use my answer [here](https://android.stackexchange.com/a/198095/96277).
---
Nuke the malware
================
Now that you know the culprit, you can disable it through GUI as stated above. If that is not possible, do:
```
adb shell pm disable-user PKG_NAME # disables the app
adb shell pm uninstall --user 0 PKG_NAME # removes the app for primary user
adb shell am force-stop PKG_NAME # only force-stops the app
```
Replace *PKG\_NAME* with package name of the malware you noted in the troubleshooting above.
That should do the trick. Furthermore, you can also consider removing the malware app permanently for all users, but that requires root access though.

The steps:
1. Connected my Galaxy Note 8 to PC, open CMD and took the logcat with basic command from withn CMD prompt:
>
> C:\Users\igorn> adb logcat > note8.1.log
>
>
>
2. As soon as the new tab with spam page was opened, I stopped the logcat capturing immediately by Ctrl-C and searched the log for "chrome":
>
> grep -i chrome note8.1.log
>
>
>
Last ten of found lines revealed the suspicious:
02-03 09:43:14.443 3931 4232 D GameManagerService: handleForegroundChange(). pkgName: **com.qrcodescanner.barcodescanner**, clsName: **kotovich.kotovich.kotovich.kotovich**.ScannerChromeActivity,FgActivityName:com.qrcodescanner.barcodescanner/kotovich.kotovich.kotovich.kotovich.ScannerChromeActivity,userID:0
3. Than I went to application list in device settings and saw the Barcode Scanner. Checked it on GoolePlay and found a plenty of 1-star reviews for exactly same malware behavior!
As well I noted that this application got last update two days ago, that match perfectly the timing - the problem started to appear exactly two days ago! Bingo!
4. Uninstalled it and the problem gone! Happy end :)
For infomation only: neither of other approaches like installing BitDefender, MalwareBytes, etc worked for me, so I was simply happy to sort it out!
So thank you, **username_2**!
Upvotes: 2 <issue_comment>username_4: So I was having this same issue and I kinda stumbled on a simple way to fix it.
First thing I did is I reset all the browser defaults so if ANY application wanted to open a browser it needed to ask me permission and then I can select which browser I wanted it to use.
Second I installed a browser I have never used... went into its settings and reset all its defaulted programs too so it couldnt just piggy back onto the new browser.
Then when it prompted me to select what browser that I wanted it to use I told it the new one I installed and told it to use that as default so it would put it in the browser.
I then went into the browser and found the only app that is set to use it as a default. It also showed me the last time it was used by that program and that time matched the time I told the spam thing to use the new browser as default.
In my case it turned out to be my QR code reader... I did notice its icon had changed a couple months ago. So it was either bought by a company that changed how it worked or the company was hacked and so it traveled down.
And as far as the browser goes I used the Samsung browser but I am sure the reset of them will have that last used part to make it easier for you to track down.
Hope this helps. :-)

2017/07/07 | 242 | 1,012 | <issue_start>username_0: I'm currently traveling with my phone, and my lock screen shows a dual clock with Roaming and Home times. Which is very useful! Except the Home time is actually from the timezone I originally registered the clock in, NOT the one where I currently live - I've moved timezones since I bought it. Is there any way to set the Home timezone to where I actually live while keeping the dual clock?
I'm on a Samsung Galaxy S7 with Android 6.0.1<issue_comment>username_1: And of course right after I finished writing this question, I figured out the answer. Go to Settings, Lock Screen and Security, Info and App Shortcuts, Dual Clock, and that has a "set home timezone" option. It would've made more sense to put it somewhere in the "Time and Date" Settings section, but oh well.

Having said that, nevertheless it could be that the ROM supports many languages but are **hidden** because of things like:
* CSC (Customer Service Code) location
* Region or
* Carrier
This behaviour has been noted for Sony, HTC and **Samsung** devices. Luckily there is a possible workaround in this case (yay!).
Since you have a Samsung device, you may try [Language Enabler (Wanam)](https://play.google.com/store/apps/details?id=com.wanam&hl=en) which is recommended on [this](https://forum.xda-developers.com/showthread.php?t=2709184) XDA thread.

Features :
* Choose *language to be enabled (83+ languages)*
* Display Languages on their Locale encoding
* Auto Backup your stock language settings
* Restore your stock language settings
**Important**
*This app doesn't add any language support, it just enable all supported languages, so if you don't get your local language after reboot, that means it's not supported in your ROM.*

Upvotes: 4 [selected_answer]<issue_comment>username_2: I'm aware that this is an old post, but I've decided to leave my answer here. So if anyone in the future is stuck, they can reference from my post.
Most of articles that I've found bait you to install and buy their apps.
I don't trust those apps and I sure don't want to pay any money for it.
So I've put together what I've found based on 2 reliable sources, including the answer up there.
**(Contents are pasted down below)**
Source: [How to add a new language that isn't provided by manufacturer on Android](https://github.com/cchanyu/MasterNotebook/blob/6efcd20e4fdb2f7cdc453cc595b94b55da58e328/Java/Android_Root_Access.ipynb)
**1. Enabling the developer mode:**
Developer mode allows you to gain access to more controls, but it's hidden by default.
So in order to enable Dev mode, do the followings:
**Open your Device (Phone/Tablet) > Settings > Device/Phone Information > Tap on Build Number 7 times.**
**2. Enable USB Debugging:**
In order for your PC to control your device, you need to enable something called USB Debugging and that can be found in Dev Mode
Go back to the Settings and Search up **"Developer Options".**
In the Dev Options, scroll down until you see **"USB Debugging"** option and enable it.
**3. Using adb commands on PC:**
Now you have to **connect your Android Device to your PC** using an USB cable.
Then **download [Android Studio](https://developer.android.com/studio)** from Google.
You can verify your install location: `C:\Users\[USERNAME]\AppData\Local\Android\Sdk\platform-tools`.
Or, just open Command Prompt (Terminal) and go to the root folder by typing the command below.
```
cd C:\Users\[REPLACE_WITH_YOUR_PC_NAME]\AppData\Local\Android\Sdk\platform-tools
```
Once you're in the right location, the **computer will recogize the command adb**.
You can start using adb commands. Before we get into any further, we have to go back to our Android Device.
**4. Download Language Installer App:**
There is an app called [Language Enabler](https://play.google.com/store/apps/details?id=com.wanam&hl=en) by Wanam.
After installing the app, run the following commands on your command prompt.
This command will give the app root access to your device to make changes.
```
adb -d shell pm grant com.wanam android.permission.CHANGE_CONFIGURATION
```
**5. Langauge Installation:**
Now all you have to do is to install the language using the Language Enabler app.
Go back to the app, select the language you want to install and press install.
This'll install the language and you can now delete the app and undo everything up there as we no longer need them.

What does it depend on or what does it take to enable it? What is the science behind it? Btw, I'm running the regular android rom.
Ps: it would be really nice if your answer would explain things simply for me to understand. Thanks in advance :D<issue_comment>username_1: On some devices yes... but it requires kernel support, meaning you need a custom kernel. There are several known methods of enabling it with a custom kernel and it depends on the screen type, SoC, and other factors, but in most cases it causes an additional 2-3% battery drain per hour to support DT2W or S2W because the digitizer needs to be powered all the time and the device wasn't designed for that.
Actually implementing it is more of a development question than an Android question though, it requires manipulation of the kernel code and building a new boot image and flashing it.

I've enabled USB debugging in development options and also have the latest version of Android Studio and the SDK, I've also installed the Android 7.0 package in Android Studio and the windows USB drivers from that, I've also reset both the phone and computer after one suggestion, one person even suggested updating the USB drivers for the phone in device manager on windows to the drivers(Android\_winusb) in the SDK folder but it says it cannot find any relevant drivers, also have tried adb kill-server and adb start-server.
Nothing I do seems to help at all. Also I really don't want to have to root the phone as that voids any warranty but from everything I've read there's no need to do that in order to get this working.<issue_comment>username_1: I suggest you to connect your phone to your PC, and on your computar to go on Device Manager in control pannel and remove devices related to your smartphone.
Then, disconnect the smartphone from you PC.
Restart your PC and your phone.
Connect again your Phone to your PC.
Another try:
Simply disable USB Debugging, while connected to PC.
Re-enable It and connect to your PC.

As long as:
* The appropriate SAMSUNG driver has been manually installed
* The device is in developer mode and
* USB debugging is active on the device
The PC should pick up the phone in ADB (when the PC has correctly recognised the phone, you should have a message on the Samsung device asking you to trust it). When the device trusts the PC, and the correct drivers are installed, it should show up in `adb devices`.

You would need two macros for this
(Triggers / Actions / Constraints are added by **`+`** on the right side of each panel )
**Logic:**
* *Ring on Calendar Notif Macro :* Whenever you get a notification from your calendar app, alert you with a non - stop ringing , at a volume level and sound customised by you
* *Stop Ringing Macro :* *Manually* stop the ringing using a widget on your home screen and set the Volume levels to what you would prefer in your normal device usage
Barebone implementation of this logic is implemented in Macros below. You can customise it later by experimenting

**Don't** get intimidated by the long explanation - it's detailed so that you don't waste time setting it up ; shouldn't take you more than 5 minutes to set up :)
**Ring on Calendar Notif** Macro
* **Trigger:** Notification Received → Select your calendar app → Text → Any
* **Actions**
* Set Macrodroid Variable → New Variable → Stop Ringing , Type *Boolean* → Set it to *false* (initialising variable that controls when to stop / start ringing )
* Repeat Actions ( second item on drop down when you press the plus sign on action panel ) → While condition repeat → Conditions **`+`** → Macrodroid Variable → Stop Ringing →`OK` → Select *False* and `OK`
This creates a while / do loop wherein we want you to be sued when notification arrives something to be done when . You see now a WHILE / DO - End Loop created . Tap the *End Loop* and you will get a pop up *Add action above*. Tap that and add actions below
* Volume Change → select *Media / Music* and set slider to say maximum % tap `OK`
* Play → select any sound from drop down list
* Wait before next action → set it to 2 seconds
**Constraints:** Leave blank
**Stop Ringing** Macro
* **Trigger:** Empty Trigger
**Actions**
* Set Macrodroid Variable Stop Ringing to *True*
* Volume Change - set the Volume levels you normally have on your device
**Constraints:** Leave blank
Go to the widgets section of your launcher , drag and drop Macrodroid widget to your home screen and assign it to Stop Ringing macro
**Alternative app option**

<https://play.google.com/store/apps/details?id=com.kebab.Llama>
It's an old app but very simple and powerful.
Give access to your notification by activating Llama in Accessibility settings of your phone.
* Create an event with condition as **app notification bar icon** of your calendar app
* Add action to that event as **play a sound** and choose a sound
That's it. Test the actions once and you are good to go.
*And not to forget, this app has no ads. It has no internet access at all. Salute the developer!*

How can I prevent this (without signing out of spotify)?
Android: 6.0.1

Major part of this guide was extracted here: [How to Disable Bluetooth Automatic Playback on any Android Phone](https://www.xda-developers.com/how-to-disable-bluetooth-automatic-playback-on-any-android-phone/)
The point of this guide **isn't to disable Bluetooth music entirely,** otherwise the latter can easily be achieved by:
Disable Bluetooth Music : Settings >> Bluetooth >> Your device(Car) >> Settings then uncheck audio support.
..and this simply destroys the whole purpose of the guide.
It is important to know that *autoplay* is a *feature* of many Bluetooth devices, despite the fact people do see this "feature" as a problem though, which is the original reason the original author wrote the guide.

**Understanding Bluetooth Autoplay on Android**
* What essentially happens when you connect a Bluetooth device that sends an autoplay command is that this command is seen as a KeyEvent for toggle play/pause in Android.
* Applications with a MediaButtonReceiver broadcast receiver can then react to this Media Button event.
* Android keeps track of the last application that requests to receive Media Button events.

You can actually see which application is currently set to respond to these key events by entering the following ADB command:
`adb shell settings get secure media_button_receiver`

**Disabling Bluetooth Autoplay with Tasker**
**Profile (or Trigger)**
* Goto Profiles Tab and click the "+"
* Event >> State >> Net >> BT Connected
* Tap back to exit from this window
**Task**
You will notice as soon as you exit, you will be prompted to link this to a Task
* Scroll all the way up the Task list select "New Task + "
* You can just keep it anonymous or give it a name
* Click "+" to add new Action
* Media >> Media Button Events >> Grab
* Tap back to exit from this task
*AFAIK root is not necessary for this task*

Once you’re done, Tasker should now automatically set itself as the Media Button Receiver in Android upon connection to your selected Bluetooth devices. This way, the play/pause action that is sent will not be received by any of your media applications, but instead by Tasker
Unfortunately I couldn’t get Spotify or Soundcloud music application to replicate the issue. **However, I retested this feature using a PC with the remote audio service (Bluetooth module on my PC supports that) to test the bluetooth autoplay feature.**
**Tests done**
1. Enabled Bluetooth audio service (to use PC speakers to listen to remote audio).
2. Open two different music apps on android and played music and play
3. Created a “media button grab” in Tasker to handle Media Button key events.
4. Retested (2) with Tasker running the previously created task.
[](https://i.stack.imgur.com/LXC6n.png)
**Results**
1. On test (2) the audio output was transferred to PC speakers indicating that the autoplay feature was still active.
2. After performing test (4), **the audio sound output came from android and was not transferred to PC speakers. Which essentially solves the issue.**

Alternatively..
Head to playstore and get [Bluetooth connect & Play](https://play.google.com/store/apps/details?id=com.cp2.start.and.play.music.player)
[](https://i.stack.imgur.com/xHysx.png) [](https://i.stack.imgur.com/GFl16.png) [](https://i.stack.imgur.com/QoM4c.png)
You can tell it which app should play for each bluetooth device (or to NOT play on a given BT device)

Open up your Google Chrome browser on he phone, click on the right upper corner bottom, click on settings, advance, site settings, media and turn off auto play. Bingo.
Now you can play any media when you want.

I have mine set to play a 1 second clip of silence such as [this](https://archive.org/details/1secondofsilence_201911). This grabs the playback and does not automatically continue to the prior app playing media.
I tested this on Android 13 (LineageOS 20) with a Pixel 4a.
I tried the solution suggesting to grab playback with Tasker or the `media_button_receiver` option (both rooted and not), but neither worked.

I just had this issue, and tried adding it as a contact and removing it, but it became potential spam again immediately.
However, I then tapped the phone icon next to the entry in my calls list to dial the number, and after hanging up I noticed that did the trick and now the number in question shows normally!

But most companies stop supporting old versions after a major change so it can be possible that after some time MicroSoft decides not to support the version then it will force you to install new version
Upvotes: 1 <issue_comment>username_2: You'll need to enable "install from unknown sources" setting before this works. Also you need to uninstall the latest version first and turn off Google Play autoupdate for this app.
As @deepak pointed out, this may work for sometime until a major change on Skype's backend will start crashing your app or it may start misbehaving.

2017/07/13 | 919 | 3,414 | <issue_start>username_0: I've been having some difficulty keeping a reliable connection at my house, so I installed [the OpenSignal app](https://play.google.com/store/apps/details?id=com.staircase3.opensignal) to see what might be going on. According to its map, I live in a "hole" between several different towers.
However, the pointer on its home screen doesn't seem to make any sense. It's supposed to tell me where the tower is that I'm connected to, but it seems to rotate faster than necessary to account for me rotating the phone (unlike a compass needle), and it seems to be fascinated with my home stereo speakers when I bring it close to them. (like a compass needle pointing to the speakers' magnet)
So is this a legitimate radio problem? Or is somebody's software getting confused?
---
I've gotten a lot of feedback about OpenSignal being worthless, but it was only meant to be a diagnostic tool for the problem of getting a more reliable connection. The reason to know where the towers are, and specifically the one I'm connected to, is to somewhat intelligently play with placement. (I'm mostly using the data connection for a WiFi hotspot, so an awkward location isn't all that bad.) If there's a better app or methodology, I'm all ears.<issue_comment>username_1: From app blogs [Methodology](https://www.google.co.in/search?q=open+signal+app+gives+wrong+information&oq=open+signal+app+gives+wrong+information&aqs=chrome..69i57.33827j0j4&client=ms-android-motorola&sourceid=chrome-mobile&ie=UTF-8#xxri=3) explains how they collect data
* Crowd Sourcing (already pointed in comments)
* Monitoring users who installed app continuously
So, the accuracy pretty much depends on how many people use the app with GPS *on*
* Data Analytics
Also see [Cell towers/wifi routers not located correctly](https://opensignal.com/blog/cell-towerswifi-routers-not-located-correctly/) which is dated but relevant
This app was recently launched in India and I noticed this
1. Cell towers are very well mapped of a provider, though, in my area tower density is low ( likely because provider made it open source as a part of publicity )
2. Cell towers are not well mapped, for another provider, though the tower density is much higher
Not a very dependable app , IMO
Upvotes: 2 <issue_comment>username_2: The solution to your issue would be to "fill in" the data. Crowdsourced maps require lots of data points to build a representation of the real world and you sitting in your house is really a single data point (possibly two if you alternate between cells).
Personally I recommend "CellMapper" over OpenSignal but either should work.
Methodology:
1. Open Recording App
2. Wait for good GPS lock
3. Move around the area where your cell (or sector thereof) is located/focused
Most high sites have 3x sectors (think pizza slices) so by recording points in each you triangulate the point in the middle where the site is or should be. More data, more accuracy. Below is an example of poor data (probably wrong) and an example of good data (probably close).
[](https://i.stack.imgur.com/Qv181.png)
[](https://i.stack.imgur.com/b479U.png)
Note: Once the preliminary collection is done you can manually locate the cell (they can often be seen from the street) and then fine tune the sites position.

2017/07/14 | 837 | 3,086 | <issue_start>username_0: I have recently flashed Lineage OS 14.1 (fortuna3g unofficial build, Android Nougat 7.1.2) onto my Samsung Galaxy Grand Prime Duos (G530H/DS). Everything in working order, except the rear camera. Each time when I try to access camera from other apps(Whatsapp, Banking etc.) OR opening the stock camera app, it gives me "Can't connect to camera" message.
I have tried with 3rd party apps (open camera), some online tutorial fixes (cmfix camera fix for cyanogenmod), restarting camera app, restarting phone, reflashing LOS 14.1 etc.
I went back to stock to verify that camera works fine. There is no hardware issue.
Anybody had similar problem? Were you able to fix it?<issue_comment>username_1: As this is an unofficial build so most likely this will be a bug in the rom.
Update it to latest build if problem still persists then stick to the [xda thread](https://forum.xda-developers.com/grand-prime/development/cyanogenmod-14-0-galaxy-grand-prime-t3462500) for the rom and wait for the developer to fix it or try fixing it yourself if you have experience in android builing.
Edit: By browsing through xda thread I found this [comment](https://forum.xda-developers.com/grand-prime/development/cyanogenmod-14-0-galaxy-grand-prime-t3462500/post73026988#post73026988). So it seems like there is no camera bug in new builds so you have to just update it to the latest build.
Try **clean flash** if the problem still persists.
Upvotes: 0 <issue_comment>username_2: This is a common bug in during early stages of android nougat development in custom ROM Lineage 14(cyanogenmod14), which was solved after few updates.
This problem doesn't occur in latest builds.
Possible Solutions:
1. Try to clear cache of stock camera.
2. Try to find any Official Nightly Builds(which updates regularly, otherwise contact developer and report the bug).
3. Try to clean flash(Backup user data, and wipe /system, /data, cache etc. install as new)
4. Please check whether you can turn on flash light from notification shade.
5. If you have used adoptable storage(SD card as internal), then check whether camera storage is internal or not.
Upvotes: 0 <issue_comment>username_3: Answering my own question.
My particular problem had to do with baseband and device codename, no bugs or problems with the build. For those, like me who were unaware of how this is related.
My baseband version matched the fortunave3g codename. So I should have installed that build of the of the ROM instead of fortuna3g, like I initially had. More information can be found in the device model [master thread at xda-dev forums](https://forum.xda-developers.com/grand-prime/general/master-thread-samsung-galaxy-grand-prime-t3481435)
I was unaware of the relation between the two things. But anticipating issues I had previously downloaded the three available builds (fortuna3g, fortunafz & fortunave3g). So all I needed to to was flash the appropriate build.
Everything is working fine now.
Thanks to all for the attention. Ultimately my problem was lack of awareness.

2017/07/16 | 891 | 3,433 | <issue_start>username_0: First of all, my SD card is not corrupted and I can access all my files with TWRP recovery file manager after entering my pattern to decrypt my storage, all of my files are not corrupted either. This question is not about how to restore files.
My Android 6 phone (Alcatel 5010D) fails to mount internal SD card on boot as adopted storage. It does mount the card only at /mnt/expand/5cf86564-54ca-4bbf-85e7-1f491f7ef923 (/dev/block/dm-1) but my /sdcard directory is empty (actually, it is a link to /storage/self/primary which in turn is a link to /mnt/user/0/primary). In settings > Storage & USB I can see my SD card, it says "8.21 GB used of 28.50 GB" (this is correct). But if I click on it, Apps, Images and everything else are using "0.00 B" which obviously is not correct. I have plenty of applications and some images. If I click "Explore", it shows empty screen.
So, how can I manually mount it? Or at least understand why Android does not do it automatically anymore? I have root access.
Please note that I know for a fact that mounting /sdcard manually is possible. TWRP recovery does this somehow, and I can access all my files in its file manager. In the past I was able to fully recover by copying all of them with adb pull while in TWRP recovery, format SD card for internal storage, copy everything back and then it works again normally. But sometimes Android stops mounting internal SD card on boot automatically for no apparent reason. If I knew how to do it manually, I would at very least had a quick fix for this issue and perhaps I could understand why Android fails to mount it automatically. I tried to Google an answer to this question, but usually I find methods like to mount encrypted storage on PC which is not what I'm looking for.
Also, as I already mentioned, my SD card is not physically corrupted, and I can read all files on it just fine. I know how restore everything, I'm aware of an option to format SD card as portable. But I would like to try to fix the issue at hand without reformating my card.<issue_comment>username_1: I got a similar issue, my sd was defined as internal memory in my moto E 3gen, Checking the surface everything was clear but like you the sd does not mount
and format is RAW(+GBT) so unreadable on any kind of OS + certainly secured by Motorola process
My workaround was to use "HDD Raw Copy Tool" make a clone in a file then copy this clone to a new fresh sd card
New sd card mounted successfully in moto E and I can then make a backup of my 1700 pictures
On old SD , I try then to format or change GBT to MBR but something wrong with it, so I guess the SD card is really corrupted or damaged

1. Backup old card (whole disk) as an image using ddrescue, save decryption key on your computer
2. Remove adopted card
3. Take a new card, format as internal, migrate data to this card, save decryption-Key on your computer, shutdown phone, remove new card
4. mount image and new sdcard unencrypted to Folder A and B
5. rsync A -> B
6. new card into phone, start debugging
7. Reset SELinux permissions using
**restorecon -R -v /mnt/expand/[yourpartition]/**\*
as root in adb shell.
This did the trick for me. The new card did not vanish anymore and keeps persistently mounted.

Set Chromer as the default browser in your phone. From there on, any link you try to open in your phone will be presented in a custom tab. You can also not do this and choose to open link in Chromer when prompted.

The default is usually to use the in app browser.
You have to find this setting in each app and change it.
Chromer is a nice way to manage links opened from other apps (Web Heads) but AFAIK has no control over if other apps use it.
If somebody knows a one shot method to change the browser settin for all app I am all ears.

2017/07/16 | 961 | 3,598 | <issue_start>username_0: Have to mention this to avoid possible confusion, this question is *not* duplicate. This question is specific to **using adb to uninstall a package**. There are several similar questions but are all different from this one, as they're focused on removing an application by any means.
*Please do not provide answers using "rm" command to delete the package files. Also, answers related to malformed package names, or trailing carriage returns. I think they're pretty much all covered in all the other questions.*
I had `pm uninstall` functionality but after ROM upgrade. Some things won't uninstall anymore. For example the following two system apps (which I removed under previous ROM, significantly improving overall performance):
/system/priv-app/SecurityCenter/SecurityCenter.apk=com.miui.securitycenter
/system/app/Updater/Updater.apk=com.android.updater
Now I get an error trying to pm uninstall them: **Failure [DELETE\_FAILED\_INTERNAL\_ERROR]**
But other **system** apps (which won't uninstall through regular android interface) do uninstall via `pm uninstall` command. Example:
/system/priv-app/Browser/Browser.apk=com.android.browser
So both are system apps, what could be the difference between them?
For reference, I upgraded from MIUI 8.1.6.0 to 8.5.3.0, and re-installed TWRP and SuperSU. This question is not specific to my ROM, as I see other people are in the same situation. But I seem to have an advantage being able to be able to uninstall some system apps. And am willing to contribute, to find a solution for everyone, to uninstall any app.
I tried: mount -o rw,remount /system
but that didn't solve it.
Please help out with any ideas along the way. Thanks!

*`Update 1`* - Confirming steps to avoid intermittent issues
\* Wiped all partitions in TWRP
\* Installed Latest ROM (MIUI 8.5.3.0)
\* Went back to TWRP, wiped only /Data
\* Restored /Data from backed up version of the ROM that came with device (MIUI 8.1.6.0)
\* Now after I boot into OS, ROM shows as latest (MIUI 8.5.3.0) in settings
Now I am able to pm uninstall every app I've tried. Even the most resilient: Google APP, Updater, Security.
This Frankenstein.. err I mean hybrid ROM works fine so far, and I've already removed many system packages, making the phone (Redmi 3S+) visibly faster. But I would still like to pinpoint what was causing this to make it into *Generic Solution*. So, if it ain't broke I'm willing break it, so next time it breaks we will know what's causing it and how to fix it.
*`Update 2`* -
\* Wiped all partitions and restored all partitions from Original ROM.
\* Restored to factory settings (using TWRP)
\* and after booting into ROM, went back to TWRP and made another backup
\* Using same scenario as in Update 1 above, with only exception of using /Data from here. pm uninstall does *not* work.
Any thoughts on the differences between the two /Data partitions I should be focusing on?<issue_comment>username_1: I succeded adding the **-k** and **--user** options to the **pm** command, e.g.:
```
pm uninstall -k --user 0 com.android.service
```
The command was issued as root, no need to remount /system as rw. Android on the phone is 6.0 and the package is a system app. Without the extra option I get the error:

Yes, Chrome is trying to be like WebView with multiple similarities, but it is different. There is no plans to get rid of until Chrome can catch up, but it has a long ways to go.

2017/07/17 | 787 | 2,893 | <issue_start>username_0: Is there any app, tool, ROM, etc. for Android that lets you restrict selected individual permissions of an app, ONLY when it is in the background?
This should function similarly to the "Restrict background data" feature that help reduce mobile data usage by preventing background apps from using network resources.
For example, you may want an app to have access to your location when you're actively using it, but you don't want it to keep the GPS on in the background, either because it drains the battery and/or is tracking your movements.
Same thing with other permissions like accessing the microphone and camera; because it is very rare for most people to intentionally record audio/video/photos from a background app. Other examples are: send SMS, reading/modifying contacts, write to internal/external storage.<issue_comment>username_1: From Nougat onwards Chrome *is* web view.

><issue_comment>username_1: From a privacy perspective, any app that requires more permissions than its actual usage is not a secure or private app. Is there a valid reason why they would need your call information? Is the software related to managing calls? From what I can tell, not really. You can never trust developers for their words. Many people in the past claimed they will not spy or collect additional data even with permissions, many more people will do that in the future, yet there are a lot of them who do break their "promise".
I am personally relatively paranoid, so if an app is just a news browsing app, if it requires permissions like my SMS history or anything more than its initial purpose, It is a massive no go.
Upvotes: 2 <issue_comment>username_2: I'm part of the development team of the Sheepoll App. Glad you came up with the question.
When developing an Android app, you have a lot of Android hardware/software functionalities that require permission to be used.
These permissions are declared in a "Manifest", basically a file that says:
* This app needs internet
* This app needs to use the device camera
* This app needs to write data to the external storage.
And so forth.
After investigating, we found out that unnecessary permissions indeed were being requested by our app. These permissions have been added by default during our development phase. This issue has been identified and fixed, as seen [here](https://github.com/facebook/react-native/issues/5886).
These permissions will be removed in the next release of the Sheepoll App. :)

2017/07/18 | 337 | 1,440 | <issue_start>username_0: I've a complex problem.
My phone refuses to turn its screen on. Its touch screen has proven to still work, but it just simply refuses to open the screen.
I bought a new phone, but my problem consists of the fact that my wireless headphones are still paired up through bluetooth to the phone that wont open its screen anymore.
I dont remember how to navigate to the bluetooth screen in the settings with a black screen.
My problematic phone is an Allview P6 Qmax.
My headphones are a Panasonic RPBTD5K.
I would like to know if its possible to use... Maybe a third party program, thats capable of unpairing my problematic phone from my headphones.
Or if my headphones have a command to unpair from what they're paired with.
Thanks.<issue_comment>username_1: I've found that I can long press the power button on the headphones to unpair them from the phone. Thanks me.
Anyhow, if anyone here does know the answer to some third party program or some other solution to unpairing bluetooth devices from unresponsive phones, please comment for future visitors.
Upvotes: 2 <issue_comment>username_2: The headphones probably connect to the last device they were connected to. Just move your phone away a certain distance so that the headphones are out of reach for the bluetooth to connect. Then connect the headphones to a different device, to stop it from automatically connecting to your broken phone.

I have it set up on the tripod and then go and set up whatever I'm shooting and after 2 minutes, the camera always exits and goes back to the launcher screen.

2017/07/18 | 1,094 | 3,762 | <issue_start>username_0: Many of us Android users have probably already heard of [Greenify](https://play.google.com/store/apps/details?id=com.oasisfeng.greenify) – an app that can automatically hibernate apps as soon as you turn off the screen. That even works while keeping their GCM functionality working – so whenever a cloud message for them comes in, they get awake again.
Unfortunately, that wakeup only works with GCM. Now I want to hibernate a non-GCM app, but have it awaken in intervalls (eg. de-hibernate it all 30 min for 1 min, then auto-hibernate it again).
**Is this possible – and if so, how?**
My device is rooted, the XPosed framework is installed, and [tasker](/questions/tagged/tasker "show questions tagged 'tasker'") available as well – so solutions involving one or more of those criteria are perfectly welcome as well.<issue_comment>username_1: Oh well, oh my … question almost included the answer. Still needs some testing (I've just set it up now), using [tasker](/questions/tagged/tasker "show questions tagged 'tasker'") which has a *Greenify* plugin:
>
> * **Condition:**
> + *Event › Display › Display Off*
> * **Task:**
> 1. *Task › Wait:* 20 s (just in case)
> 2. *Task › Anchor:* (Name, optional step)
> 3. *Plugin › Greenify › Hibernate:* Pick the app
> 4. *Task › Wait:* 30 min (or however long you want to have the app hibernated)
> 5. *Plugin › Greenify › Wakeup:* Pick the app again¹
> 6. *Task › Goto:* Action Number, 2
> * **Exit Task:**
> + *Plugin › Greenify › Wakeup:* Pick the app again¹
>
>
>
**Note:** That's how I ***would*** set it up. Had to skip the exit task as *Tasker* won't let me add one. So that's the crux here: I have to trust *Tasker* to restore the "previous state" correctly. If that doesn't work, I'll have to create a second profile for *Event › Display: Display On* (which would, being an *EVENT,* fire when the display will be *turned* on – it's not a state) and have a single task to do what otherwise the exit task would do.
**Note 2:** In order for this to work, you need to add the "target app" to Greenify's hibernation list first (i.e. tell Greenify it should hibernate it when turning the display off). If you don't do that, it won't ever be hibernated at all.

¹ if your app doesn't react on the wake-up command, see [Xavier's answer](/a/179699/16575) for an alternative shell command to try
Upvotes: 3 [selected_answer]<issue_comment>username_2: I found out some of the hibernated apps wouldn't respond to the Greenify *Wake* command, instead I used the `start service` command to "wake" the target application (without opening its UI)

* Tap back to exit from this task
* Click "+" to add another action
* Task >> Goto [Action Number, 2 (anchor task)]
Like @username_1 said you can rely on Tasker 'previous state' to reset the config, because adding an exit task is not probable
My workaround simply involves starting the service of the hibernated app (IMO=waking the app) because sometimes the app won't wake up using the Greenify *wake* option as I previously encountered :)

2017/07/19 | 2,383 | 8,068 | <issue_start>username_0: For PC RAMs, when a manufacturer say they produce a 4GB memory bank, they are producing a memory bank with 4,294,967,296 bytes (4 **GiB**). The same applies to CPU cache, i.e. a CPU with 2MB L3 cache means 2,097,152 bytes (2 **MiB**) of L3 cache.
For hard drives, flash drives (USB drives, SSDs, eMMCs and UFSs) and optical discs (CDs, DVDs and BDs), manufacturers use powers of 103 for B, KB, MB and GB, so a 4GB USB drive has *roughly* 4,000,000,000 bytes.
According to my observation, Android phone manufaturers use the latter kind of units when advertising RAM. That does not sound reasonable to me because PCs' RAMs aren't advertised that way.

**Evolution of Mobile Phones and Standards**
* The [earliest commercial model phone DynaTAC 8000X](https://en.m.wikipedia.org/wiki/Mobile_phone)appeared on the scene in 1983. [It couldn't do anything more than basic calls](https://en.m.wikipedia.org/wiki/Feature_phone) so RAM doesn't come into play
* By [1987](https://en.wikipedia.org/wiki/Timeline_of_binary_prefixes) hard drives were marked in **SI** units as can be seen from the binary timeline linked
* **Feature Phones:** [IBM Simon](https://en.m.wikipedia.org/wiki/IBM_Simon) was the first feature phone in 1994, which had 1 MB of RAM and 1MB of storage expandable to 2 MB - you read that right :) So, when the feature phone cane out , SI standards were in vogue
So, *likely reasons* :
* SI standards were automatically applied to mobile memory as they were more viewed as storage elements rather than computational requirements
* Fact that memory was / is not based on platters (see accepted answer ) , adopting binary system made no sense . Instead of having separate nomenclature for storage and RAM, SI units were adopted for both. But in the case of PC's legacy continued, though one could argue that it is incorrect. Mac OS since
has since version 10.6 (Mountain Lion in 2011) shown hard drive size using [decimal prefixes and continues to do so](https://en.m.wikipedia.org/wiki/Binary_prefix)

This is true even for phone manufacturers, in fact just as [rjknight](https://news.ycombinator.com/item?id=7540344) pointed out, The RAM marketing strategy is similar to the "hard drive maker conspiracy" story is driven by the fact that manufacturers have no real incentive to switch to binary prefixes, because that would make their drives (RAM in this case) look "smaller".

AFAICT, using the **mebibyte (MiB)**, **gibibyte (GiB)** and so on, is a more accurate way of presenting the volume of data stored in these quantities.

These other binary prefixes (kibi, mebi, tebi, etc.) were introduced in an attempt to reduce such confusion, but these prefixes have yet to see widespread adoption.
In PC 2GB of ram refers to gibibytes, not gigabytes. RAM comes in allocation in powers of 2 due to architecture. Memory addressing is done in binary form, this implies it is going to be a power of two.
So, since writing memory addresses in binary always results in a binary number, RAM developers have (almost) always stuck to creating RAM in units of powers of 2, combining individual chips which are (almost) always combining to powers of 2.
Here is another [explanation](https://www.reddit.com/r/explainlikeimfive/comments/jcsqg/why_does_ram_come_in_specific_sizes_256_512_1024/):

And as expected, the exact number of bytes in a DRAM module is always an integral power of two.
**Conclusion**
This is is more like a business idea, that takes advantage of confusion regarding the common usage of "gigabyte" instead of "gibibytes" much like ISPs advertise 8Mbps (= 1MBps) as 8MBps, so it needs awareness from end users or customers.
It seems most manufacturers hide under metric system or SI units to "advertise" to the unsuspecting consumers, although in real terms the say what they don't mean.

**Evolution of Mobile Phones and Standards**
* The [earliest commercial model phone DynaTAC 8000X](https://en.m.wikipedia.org/wiki/Mobile_phone)appeared on the scene in 1983. [It couldn't do anything more than basic calls](https://en.m.wikipedia.org/wiki/Feature_phone) so RAM doesn't come into play
* By [1987](https://en.wikipedia.org/wiki/Timeline_of_binary_prefixes) hard drives were marked in **SI** units as can be seen from the binary timeline linked
* **Feature Phones:** [IBM Simon](https://en.m.wikipedia.org/wiki/IBM_Simon) was the first feature phone in 1994, which had 1 MB of RAM and 1MB of storage expandable to 2 MB - you read that right :) So, when the feature phone cane out , SI standards were in vogue
So, *likely reasons* :
* SI standards were automatically applied to mobile memory as they were more viewed as storage elements rather than computational requirements
* Fact that memory was / is not based on platters (see accepted answer ) , adopting binary system made no sense . Instead of having separate nomenclature for storage and RAM, SI units were adopted for both. But in the case of PC's legacy continued, though one could argue that it is incorrect. Mac OS since
has since version 10.6 (Mountain Lion in 2011) shown hard drive size using [decimal prefixes and continues to do so](https://en.m.wikipedia.org/wiki/Binary_prefix)

This is true even for phone manufacturers, in fact just as [rjknight](https://news.ycombinator.com/item?id=7540344) pointed out, The RAM marketing strategy is similar to the "hard drive maker conspiracy" story is driven by the fact that manufacturers have no real incentive to switch to binary prefixes, because that would make their drives (RAM in this case) look "smaller".

AFAICT, using the **mebibyte (MiB)**, **gibibyte (GiB)** and so on, is a more accurate way of presenting the volume of data stored in these quantities.

These other binary prefixes (kibi, mebi, tebi, etc.) were introduced in an attempt to reduce such confusion, but these prefixes have yet to see widespread adoption.
In PC 2GB of ram refers to gibibytes, not gigabytes. RAM comes in allocation in powers of 2 due to architecture. Memory addressing is done in binary form, this implies it is going to be a power of two.
So, since writing memory addresses in binary always results in a binary number, RAM developers have (almost) always stuck to creating RAM in units of powers of 2, combining individual chips which are (almost) always combining to powers of 2.
Here is another [explanation](https://www.reddit.com/r/explainlikeimfive/comments/jcsqg/why_does_ram_come_in_specific_sizes_256_512_1024/):

And as expected, the exact number of bytes in a DRAM module is always an integral power of two.
**Conclusion**
This is is more like a business idea, that takes advantage of confusion regarding the common usage of "gigabyte" instead of "gibibytes" much like ISPs advertise 8Mbps (= 1MBps) as 8MBps, so it needs awareness from end users or customers.
It seems most manufacturers hide under metric system or SI units to "advertise" to the unsuspecting consumers, although in real terms the say what they don't mean.

1. Install Nova Launcher and run it
2. Long press on your Nova Launcher home screen
3. Press and hold to add an **ACTIVITIES** widget (should be near the top)
4. From there choose a Settings widget
5. Choose Notification Log
6. Select your new Notification Log to access the Android Notification Log.
I don't know why Google hid the notification log widget and judging from the huge number of apps in the Play store that offer to record notifications for you, it really is a sought after feature. Thanks to Nova Launcher for making such a great app!

2017/07/20 | 845 | 3,401 | <issue_start>username_0: Here's what I need. I run a business, I use my personal Android phone (Samsung Galaxy S8) for 100% of my calls. It's not a problem. But I have a lot of clients whose numbers I don't have memorized. I could put a hundred contacts in my personal phone so I would know who's calling, but, I don't want to fill up my phone's contact list with people I only talk to occasionally.
When I look at my contact list, I want to see my friends and family only. Is there an app that will handle sort of a 'secondary phonebook' with business contacts only, that will still work with caller ID?
And if you are going to comment 'you need a second phone for business stuff', don't bother. That's not what I want to do, and that's not what I'm asking. This is a question about whether there is a particular Android app that will solve my problem (or an Android setting), not anything else.<issue_comment>username_1: You can use the Google contacts app with two Google accounts and swap between the accounts easily as necessary.
([Here](https://play.google.com/store/apps/details?id=com.google.android.contacts) is a link to the Google contacts app.)
Or if you're using a Galaxy S8, you can have separate contacts in the secure folder.
Upvotes: 0 <issue_comment>username_2: I have saved separate phone contact lists as vCard files-one for business and another for private use. another for frequently dialed numbers (hybrid of both pvt+biz). It is tedious but depending on my need i load(import) one from my collections above. Hope this method helps.
Upvotes: 2 <issue_comment>username_3: I had the same issue and couldn't find an app to fix it so I decided to create one.
You can check it out [Secondary Contacts](https://play.google.com/store/apps/details?id=nothingapps.com.secondarycontacts)
It's an entirely separate contacts list that can't be read by other apps. Has caller ID too and you can import/export contacts to and from the main contacts app
Upvotes: 0 <issue_comment>username_4: The best solution I could find is [OpenContacts](https://f-droid.org/en/packages/opencontacts.open.com.opencontacts/). It's a completely separated contact book that comes with good integration, but without letting your contact information slip through it's own container. No contacts will be shared to other apps like WhatsApp.
It's my choice when it comes to handling business contacts while ensuring GDPR compliance. I even use [NetGuard](https://f-droid.org/en/packages/eu.faircode.netguard/) to disable internet for OpenContacts just to be safe.

2017/07/21 | 953 | 2,607 | <issue_start>username_0: Is the 'global' model of a phone the same thing as an 'international version?'
I'm shopping for an S7 edge, and I've heard all over the internet that the international version doesn't work with Samsung Pay.
Also, this may be a dumb question, would a model such as the SM-G935FD (a Taiwan model) be considered an 'international version?'
Is the distinction thus:
--US--
SM-G9350
SM-G935A (AT&T, Cricket USA)
SM-G935P (Sprint, Boost, Virgin USA)
SM-G935R (US Cellular)
SM-G935T (T-Mobile, Metro PCS USA)
SM-G935V (Verizon USA)
--International--
SM-G935F (Global)
SC-02H (Japan Docomo)
SCV33 (Japan au)
SGH-N611 (Japan Docomo)
SM-G935D (Japan Docomo)
SM-G935FD (Taiwan)
SM-G935J (Japan au)
SM-G935K (Korea)
SM-G935L (Korea)
SM-G935S (Korea)
SM-G935W (Canada)
[I got this list from <http://willmyphonework.net> - I use this site as I'm phone shopping to check whether a certain model will work with my carrier] (this example is to help me further understand, you see. Edit/shorten as you see fit.)<issue_comment>username_1: As for the 1st question, CDMA(Verizon and Sprint) is often referred to as Global.
For the 2nd, for Samsung Devices I'm pretty sure all international variants are the ones with Exynos CPUs instead of Qualcomm ones. So yes, the Taiwanese phone would be international.
Upvotes: 0 <issue_comment>username_2: Okay, so I chatted with a Samsung representative, and they informed me that their global model phones are indeed considered international. In re-reading my question now, I realize my question may not have been as clear as it could have been- I'm in the market for a new S7 Edge, and so was curious about what it meant when one of *Samsung's* phone models was "global," such as the SM-G935F.
So, the rep said the global model, and any non-US models (Japan Docomo, Taiwan, Japan au, Korea, Canada, etc) are considered international. He also confirmed that they do not currently work on Samsung Pay, and he does not know when this will happen, if it does.
So this is correct:
**--US--**
SM-G935A (AT&T, Cricket USA)
SM-G935P (Sprint, Boost, Virgin USA)
SM-G935R (US Cellular)
SM-G935T (T-Mobile, Metro PCS USA)
SM-G935V (Verizon USA)
**--International--**
SM-G935F (Global)
SM-G9350 (China) [credit: Andy Yan]
SC-02H (Japan Docomo)
SCV33 (Japan au)
SGH-N611 (Japan Docomo)

SM-G935FD (Taiwan)
SM-G935J (Japan au)
SM-G935K (Korea)

***Please note that I do not want to root my phone. I had previously rooted my other phone with kingo root, but could never unroot it.***<issue_comment>username_1: Unfortunately, that is just not possible. The apk of system apps resides within system partition. The privileges (access rights) required to make changes in system partition are not given to ordinary users. We can only gain such higher privilege through rooting.
That said, if you are dealing with space issues than you are looking at wrong front. System partition has nothing to do with those space issues since only a system wide update/upgrade makes changes in it. They are caused by data partition. It is possible that you may have updated some system apps, so now, they would be having an apk in system partition and another apk (the latest update) in the data partition (now that is one precious space). You can delete the ones in data partition by disabling that system app. When you attempt to do that you would get something like this:
[](https://i.stack.imgur.com/M20TW.png)
OK, and the apk from the data partition would get deleted.

You'll need to have an unlocked bootloader (look up a guide for your system—note that this is different from rooting and carrier unlocking), and doing this will take some familiarity with adb and fastboot. If your concern is just space, I would stick with username_1's advice, as doing this would be a lot of effort for very little space saving.

use osmonitor app, it will find the apps that at are using up ram , and you can remove them.
Finally use a firewall, i use 'no root firewall' and it disables access to the internet by app, you whitelist the apps you need to access internet. eg Gallery was pinging the net, and why? photos are local

Use your tv remote to control it.
As long as your tv supports hdmi cec you can control the firestick with the tv.
Just make sure hdmi cec is enabled in tv settings as well as in firestick settings.
If that doesn't work, try a powered usb otg cable and plug in a usb controller that has xinput or plug in a playstation controller or xbox one controller via a micro usb cable.

How do I rename entries in Google Authenticator?<issue_comment>username_1: Touch the entry you want to rename for maybe one second (until it's selected), then use the three-point-menu to rename it.

On the top of the screen, you'll see edit icon (pencil) allowing you to rename the entry.
Click on the pencil and rename the entry.

The problem with this is many use a sub domain and domain as the first part so you can't even see the second part (which can be changed).
Google really should fix this.

2017/07/25 | 696 | 2,982 | <issue_start>username_0: The other day, my friend told me that completely stock Android could run as a ROM on any device you care to mention. Since basically everyone else has told me otherwise, I decided to verify his claim and stumbled accross [this Android Enthusiasts StackExchange thread.](https://android.stackexchange.com/questions/176538/can-i-install-stock-android-7-n-on-any-device)
I accepted the answer that was marked as correct, but it got me thinking. If stock android cannot be run on any device, how do custom ROMs like CyanogenMod or anything else support so many phones? Thanks.<issue_comment>username_1: CyanogenMod/LineageOS and other custom ROMs can't run on every device either. They have different versions for different devices. For example check [this list](http://download.lineageos.org/) for the newest LineageOS-compatible devices.
The same version can't work on every device, because the operating system (in this case the android) have to include the drivers for the specific device it will ran on. An android version which would include all the drivers would be illogically huge.
Upvotes: 3 [selected_answer]<issue_comment>username_2: It depends what do you mean with "stock Android" you two didn't understand each other I think. I'll explain you how some things work so you can understand what's going on:
It's about how you define "stock Android" if by stock you mean the one shipped with phone (Samsung, LG etc.) or you think on pure Android aka AOSP. The stock Android is placed on nexus/pixel devices Motorola and few others, other manufacturers use Android but the add something their theming and such things (Samsung - TouchWiz, Huawei - emui and so on..) so it's stock on that phones. So if you take any rom of Samsung and try to install it on any other phone you will fail. Android is just a system it needs drivers so it can communicate with hardware, it's not like on PC where you install OS and then search for drivers (until windows 7, linux is some other story). Android ROM is like it Windows XP is made for only one configuration for example "x" cpu, "y" gpu, "z" hard disk and also particular manufacturer and it won't work if there is "w" cpu instead of "x". With custom ROMs things go like this: lineage os provides source code for operating system and other users who may or may not have contributed to making lineage os are providing so called "device trees" and kernel source code (published by phone manufacturers but sometimes needs some changes to make things work, also unique for every model of phone so one can't be used in two or more different models), so lineage os source code, device tree, and kernel sources are used to make rom - compile it for particular phone model, there are also proprietary files which are files used by some hardware but it's not open source so you need to extract it from phone. So no rom can be used on two or more different models even if are they from same manufacturer.

I cannot access anything on Google App since it immediately switches to Chrome.<issue_comment>username_1: Actually from the looks of things, Google has implemented Chrome custom tabs feature. The Google app now opens search results as Chrome Custom Tabs.

Turned out it was caused by the Qustodio Parental Control app. It blocked safe search which was forcing the Google app to open google search in Chrome because google would not allow the parental control app to enforce safe search and monitor its app .
Don't know if its that but here is Qustodio help article telling that :
<https://www.qustodio.com/en/help/article/2832549/> (under heading "Safe searches on Android")
If you don't have Qustodio Parental Control app, maybe it could be some other app that high control on your device. Qustodio shows at this link what i mean by high control (ex. Apps with usage access, Accessibility, etc) - go to the step called "11. When prompted to Activate app supervision, choose Activate Now.".

If I connect my phone to the wifi, the computer and other phones and laptops connected to the same wifi will run slowly; videos buffering for indeterminate amounts of time or not at all, web pages failing to connect, ping issues while someone is playing games on the computer and also issues with packet loss (so I'm told).
I never had an issue with this while using these same wifi connections in question, until I updated my phone a couple of months ago. I couldn't definitively say the version of Android software that I updated from because I'm not really savvy with this kind of thing and I can't remember.

2017/07/26 | 455 | 1,805 | <issue_start>username_0: On my Android phone (Sony Xperia Z3 Compact), I have a situation where it sometimes goes very sluggish, and the battery drains quickly.
This seems to happen after roughly once a day, and lasts until I restart the phone.
I haven't been able to get any useful info out of the battery info in settings, although the %s there sum to quite a bit less than 100%, so I'm concerned there is some dodgy system process killing my phone.
Is there any way I can get a list of all processes and current cpu usage? I've had a look in the play store but not found any apps that can do this.<issue_comment>username_1: Sounds like you have a lot of background activities running, you could just go to

It shows a list of all applications which are running, for how long, and the amount of RAM they are using. If you tap on the app it will also list those services of the app which are running and allows you to force stop each service.

Turn it on through "Settings" > "Developer options" > "Monitoring": "Show CPU usage". Turn it off when you don't need it, because it takes up a lot of screen space.

2017/07/26 | 1,043 | 3,675 | <issue_start>username_0: I am going to install Lineage and I need to decide which version of open Gapps to use.
I use lots of Google apps (Google Play Store, Gmail, Calendar, Photos, Music, Google search, Translate, Keep etc.). But, I am fine with installing them one by one, from Google Play store. So, I prefer a minimalist version so that, I don't need to keep anything that I don't use. Therefore, my first thought was Pico Gapps. But, this version does not include offline speech recognition files. Can these be installed later from the google store? Or, if I want to be able to use the "ok google" voice command, do I need to install Nano Gapps?
Also, are there any other obstacles I am not aware of? I want to be able to install anything else from the play store (and not to be forced to flash anything later).<issue_comment>username_1: You can download Gapps package for your lineage from this website source [opengapps.org](http://opengapps.org/).

1. Is it possible to unlock phone with any software? As android manager says that data will be wiped out as soon as my phone will be connected to internet. But, I am worried if it possible for anyone to unlock my phone. (I had 3\*3 pattern lock).

That's the problem. But you still have access to status bar, which is a part of System UI. So here comes the 1st solution:
* Boot your phone as normal, then unlock it. You should see a blank screen with only your wallpaper (or black screen) **with a normally-functioning status bar**.
* Drop down the status bar and there should be an entry to your Settings app. Tap it to open settings.
* Turn on USB debugging and connect your phone to a computer.
* From your computer, download an APK of a launcher app of your choice. Place it somewhere and grab an `adb` executable.
* Open a command prompt (terminal) and enter
```
adb push name-of-your.apk /sdcard/
adb install /sdcard/name-of-your.apk
```
* Wait for installation to complete. If it takes more than a minute, reboot your phone and it should be OK. You will be prompted to select the default launcher app with only 1 option.
Alternatively as suggested by *Једнор<NAME>је*, as a 2nd solution, you can send the APK via bluetooth and install it from the notification bar.

Once it completes installing, unlock your device and press the Home key and you should be brought to the first time use screen for the launcher you installed and have access back into your device to enable USB debugging or anything else you need to do to reinstall your ROM.
Note that I believe Nova Launcher is installed with Beanstalk (at least some versions) as it's default launcher, so if you install that from the Play Store you are likely in the same condition as you would be in reflashing the ROM except the launcher will not be installed as a system app (which you could fix with apps like Titanium Backup).

2017/07/27 | 952 | 3,966 | <issue_start>username_0: I have a problem: my house wifi goes down a lot for some unknown reason, and so I turn on data to continue whatever conversation I was having on my laptop on my phone. Then I forget to turn on wifi when the internet comes back on, and I watch YouTube videos on my phone. This, in turn, eats up 500mb of my 1gb data plan. This has happened three data cycles in a row.
When I select the YouTube app in the data section of my settings, even when I select the "restrict background data" option, and even when I go into YouTube's settings and select "only stream HD video on wifi", it still uses data. It seems like there is absolutely no hope for preventing this app (or any general app for that matter) from using any data at all.
I couldn't even find a good third-party data management app that has this functionality. Every app I've found only allows me to read and analyze my data usage and set 'timers', but no way to completely prevent specific apps from using any data. I decided I would just completely eliminate YouTube, which was annoying in and of itself because it seems there's no way to uninstall a factory-installed app. I ended up just disabling it in my settings, and then blocking it entirely with a third-party app called Boomerang.
Please, is there any simple way to completely block all data usage of only a specific app? Why is this such an unheard-of request?<issue_comment>username_1: You don't have a launcher.

2017/07/27 | 811 | 3,600 | <issue_start>username_0: This is something that I only recently noticed but many Android phones are built amounts of RAM that differ yet different versions are not distributed equally. For example, my phone from Spain has 2 GB of RAM but when bought in Asia comes with 3 GB. Internal storage is treated differently such that there are 16 GB and 32 GB versions available on both markets.
The recent Moto Z2 does the same thing. North America and Europe get a 4 GB version while in Asia, it comes with 6 GB.
Why the difference? Why offer not offer both at different price-points? Does Android require that much more memory when dealing with large character sets such as Chinese?<issue_comment>username_1: Asians, especially a significant portion of Chinese and Indians, take raw specs very importantly when considering devices for purchase. With local competitors like Xiaomi upping their game aggressively, 2GB RAM for low-end / 4GB RAM for high-end is no longer considered acceptable.
This is more than just a marketing move - apps made by local developers and companies tend to not comply with Android standards both in UI/UX design and in task/memory management. Apps would try the most devious methods to stay at the front - e.g. creating a transparent 1px floating window - just so it will not be killed by built-in memory management and consistently deliver push notifications and advertisements. Such chaotic environment with many apps constantly running in the foreground and competing for resources is detrimental to RAM usage, so having a larger RAM capacity to compensate is often considered necessary.

Adding to *username_1*'s answer, I would like to bring up another reason: **The absence of Google**.
Because the China government, driven by an evil party, does not like Google, all Google's services are blocked in China, except for Ads, Maps and Translate (the only 3 availables). Apps using GCM or any other kind of Google service will not function correctly on that part, so Chinese companies pretty much have made their own "chain services" for IPC and push notifications. These services however, does *not* comply with Google's developing standards, nor do they follow the general rules of UX and memory management. Most of them keep themselves in background by creating extra processes and use those to wake themselves up periodically, taking extra RAM, which dramatically decreases battery life and hurts UX.
Even worse, instead of having one service family exist, big Chinese companies are making their own service families one by one. So Alibaba has an Ali Service, Baidu has a Baidu Service, Tencent has a Tencent Services, and even Xiaomi has a Mi Eco Services. To make things worse, one Chinese app may use multiple services at once. Even if an app is calling a small function from a Chinese service, it may potentially wake up all apps using that service (unless terminated), and can eat up your RAM in a few seconds.
As China is a growing producer, Chinese products are selling abroad, especially South Asia (India) and Africa. By selling phones without GMS, the aforementioned Chinese service families are also spreading abroad, damaging UX to those users. However, situations seems better outside China because most foreigners do not use Chinese daily services like IM (WeChat and QQ) and online shopping (Taobao and Jingdong), and fortunately the services they use (WhatsApp and Amazon) don't utilize the Chinese services. So markets in India and Africa don't get *that* much "inflated".

2017/07/27 | 808 | 3,022 | <issue_start>username_0: I recently got a new phone and want to back up the files from my old phone (Nexus 5) before passing it on to a family member.
Using MTP connected to a Windows 10 PC the transfer is unbearably slow (around 10-20 seconds per file, even though a file may only be a few kB). Using MTP connected to a Mac using Android File Transfer is a lot faster, however the app crashes, freezes or gives an error after a minute or two and stops transferring files.
Is there a better way to transfer files, or a solution to the slow transfer speeds on Windows?<issue_comment>username_1: Have you tried another USB cord ? or if your laptop has a USB 3.0 port, use that instead. If its still the same, try using file Transfer apps from the
Play Store like **ShareIT**, **Xender** or **Snappea** etc.
Upvotes: 0 <issue_comment>username_2: When there are many files to be transferred, and small ones at that, this has been reported:
[Share Via http](https://play.google.com/store/apps/details?id=com.MarcosDiez.shareviahttp) is an *open source* app worth considering. It's handy to share with other mobile devices as well
Alternatively, you can consider other [File Sync](https://android.izzysoft.de/applists/category/named/file_sync) apps from the curated list maintained by username_4
Upvotes: 1 <issue_comment>username_3: I recommend you use a different file transfer protocol, preferably SMB or similar, to transfer the files. Somehow, MTP is buggy because speeds get significantly lower when transferring small files and takes a while to peak again.
Try file transfer apps such as ES explorer, Sambadroid, etc (I have used these with no speed issues). Even over Wi-Fi, you still get consistent transfer speeds (1-2 MB/s)
I also have written another post to achieve this [using Sambadroid](https://android.stackexchange.com/a/170986/209414). The same can also be achieved using the former [app as outline here](https://android.stackexchange.com/questions/143115/file-transfer-with-linux-pc-through-mobile-hotspot) (it is the same for Windows).
Upvotes: 1 <issue_comment>username_4: The probably fastest solution would be using [adb](/questions/tagged/adb "show questions tagged 'adb'") (check with our [adb tag-wiki](/tags/adb/info) for some background and hints for setup). To ease things up (and not gluing you to the command line), you could use a [file manager supporting ADB](https://android.izzysoft.de/applists/category/named/network_admin_adb#group_947). As you're being on Windows, my recommendation for that part would be [Droid Explorer](https://github.com/camalot/droidexplorer), written and maintained by our community member [<NAME>](https://android.stackexchange.com/users/1951/ryan-conrad).
You might consider the effort needed for an initial setup on Windows a bit much. But if you check with above linked ADB tag-wiki for what you'll be able to do with ADB (and with *Droid Explorer,* not to forget) beside the simple file-transfer task, I'll bet you'll find it worth it!

2017/07/29 | 744 | 2,641 | <issue_start>username_0: In Nox (3.8.1.1) running Android 4.4.2, I'd like to change the launcher from Nox Launcher to Smart Launcher. I set the default home app through settings, but every time I restart Android in Nox (or sometimes randomly), the setting doesn't stick and it gets switched back to Nox Launcher. Nox Launcher apparently likes to reset the default app to itself on boot. Also I can't uninstall Nox Launcher, nor can I disable it in settings:
[](https://i.stack.imgur.com/LRNRt.png)
Is there a way to make the home app setting stick?<issue_comment>username_1: I found the answer in [the video](https://www.youtube.com/watch?v=DviS8RQ2mcE) beeshyams posted in [a comment](https://android.stackexchange.com/questions/180343/permanently-setting-launcher-in-nox#comment231960_180343). There's actually a much more concise video [here](https://www.youtube.com/watch?v=YubeZjj_rBE). I've confirmed that it works correctly in Nox 3.8.1.1, so here are the instructions, which basically just involve disabling Nox Launcher by "removing" the app directly:
1. Make sure you have an alternate launcher installed first! I don't know what will happen if you try this without having another launcher installed. You're welcome to find out, but I didn't want to test it.
2. If not already set, enable root mode in Nox (*Settings → General → Root*) (note I mean the actual NoxPlayer settings in the title bar, the little gear, *not* the settings in Android), then restart Nox to apply the change.
3. Open *File Manager* then navigate to the folder */system/app*.
4. Scroll down until you find one named *launcher\_1.7.1\_en\_signed.apk* (version number / language code may be different in older or newer versions of Nox so your filename may vary slightly).
5. Rename it to *launcher\_1.7.1\_en\_signed.apk.bak* (`Long Press` *→ Rename*).
6. Now you're ready to go. Go to the Android *Settings → Home* and make sure your launcher is selected there just to be safe, and it should be good.
7. Disable root mode in Nox if you want then restart it.
To restore the Nox Launcher, just undo the filename change in the same way. If you'd rather see this all visually just watch the "concise" video linked above.
Upvotes: 3 [selected_answer]<issue_comment>username_2: Here's a shorter way to do it:
1. Enable root and install any launcher you wish.
2. Use this app to uninstall the Nox launcher (show system apps, and allow in settings to uninstall them):
<https://play.google.com/store/apps/details?id=com.lb.app_manager>
And that's it.
Disclosure: I made the app.

chmod 755 /system/priv-app/Messaging_SEP81 (Set permissions on folder)
chmod -R 644 /system/priv-app/Messaging_SEP81 (Set permissions on apk file)
ls -l /system/priv-app/Messaging_SEP81 (Check permissions - Should be: -rw-r--r-- 1 root root - not sure what 1 & 2 is)
ls -l /system/priv-app | grep "Messaging" (Check permissions - Should be: drwxr-xr-x 2 root root)

I did the following in the order as it is.
* Backed up my contents
* Unlocked the bootloader
* Flashed TWRP recovery
* Installed elementalX-G4-1.04
* Flashed SuperSU-2.82
* Wiped cache partition
Now my phone was rooted and I restored all the contents and data. All of a sudden Pokemon GO is not working and I got to know that it won't work in rooted devices since it's failing Safety Net tests. After going through some threads, I get to see that installing suhide might bring back life into the game.
I downloaded suhide0.54 and booted into recovery mode, flashed suhide0.54 and tried rebooting. Phone got stuck at Moto logo for a long time. I tried wiping cache and rebooted but still the same.
Tried flashing suhide-0.55, wiped cache partition and rebooted system. Still the same condition. Please help me out on how to get out of this situation.
Model : Moto G4 Plus
Version : Android 7.1.1<issue_comment>username_1: >

Remove SuperSu. You will find super su uninstaller on internet. Flash Magisk.
You can hide supersu in magisk menu.
Upvotes: 0 <issue_comment>username_2: You need to uninstall suhide. There is an uninstaller.
Check this post:
<https://forum.xda-developers.com/apps/supersu/suhide-t3450396>
And scroll to the downloads section. Download the file with 'rm' in the name. Transfer it to your phone and flash it in TWRP. Make sure you have the latest version of TWRP. Reboot.
I would suggest buying a cheap phone and experimenting with that. Unroot the G4 plus and do all the stuff with it that you can do unrooted.
In terms of the phone to buy to root etc, I would suggest either a used phone (make sure you can unlock the bootloader before buying) or a new moto e, maybe. If you are in the UK, I would suggest buying a used phone. You can unlock the bootloader on an HTC One M8, which you can pick up for about £90.
<https://htc-one.gadgethacks.com/how-to/unlock-bootloader-root-your-htc-one-m8-0154444/>
In the US, the new Moto E is $99 on Amazon Prime or $129 normally on Amazon.

2017/07/30 | 873 | 3,081 | <issue_start>username_0: I moved my apk file to `/system/priv-app` just as you adviced me in [this thread.](https://android.stackexchange.com/questions/180347/installing-apk-as-system-app-directly-with-root) When I'm trying to install it through clicking this .apk, Android said me that "The application has not been installed". I tried to use `adb install myapp.apk` for this purpose but again ADB gave me an error: `Failure [INSTALL_FAILED_POLICY_REJECTED_PERMISSION]` and I suppose that app requires permission which can be granted only by root. So the only way I see now is to run `adb shell` later `su` next `cd /system/priv-app` and `install [-cdDsp] [-o USER] [-g GRP] [-m MODE] [-t DIR] [SOURCE]... DEST` and that's a point because I totally don't understand this legend:
```
Copy files and set attributes
-c Just copy (default)
-d Create directories
-D Create leading target directories
-s Strip symbol table
-p Preserve date
-o USER Set ownership
-g GRP Set group ownership
-m MODE Set permissions
-t DIR Install to DIR`
```
How to set attributes to install this apk as system app?<issue_comment>username_1: You should move the APK file to `/system/priv-app`, then change its file mode to 0664 (-rw-r--r--) and change its owner to root:root.
```
chmod 0644 your.apk
chown 0.0 your.apk
```
Then it should be fine.
Upvotes: 1 <issue_comment>username_2: I think you misunderstand the whole process. You are not supposed to use install command or the likes of it anywhere in the process [I mentioned](https://android.stackexchange.com/a/180358/96277). You simply:
1. [mount the system partition in rw mode](https://android.stackexchange.com/a/110928/96277)
2. copy-paste the apk into the location,
3. set the appropriate permissions using busybox's chmod and chgrp or through inbuilt tools:
```
adb shell su -c chmod 644 APK # replace APK with your apk's absolute location, such as /system/priv-app/xyz.apk
adb shell su -c chown root:root APK # replace APK as said above
```
4. do a reboot.
Follow those instructions religiously. You can altogether avoid the commands using a file manager app such as Solid File Explorer, ES File Explorer, etc.
During the following boot the Android would detect the apk and install it automatically.
Upvotes: 3 [selected_answer]<issue_comment>username_3: As suggested by @username_2, you can eliminate the hussle of entering commands (and possibly reduce the likelihood of errors) using a file explorer such as the one mentioned already.
For instance with ES explorer, simply long press the target `.apk` file and choose properties then edit:
[](https://i.stack.imgur.com/b31AUl.png)
Afterwards you get proper permissions i.e `-rw- r-- r--` and owner i.e `root`:

Looking through settings, apps, there seems to be a way to switch the default program for everything except alarm clocks.
Thank you<issue_comment>username_1: I'm not sure if the problem solved itself, or if it was something I did. Instead of OK Google set alarm, I did OK Google "specific alarm app" "time" , and it now defaults without having to specify the app anymore.

When it prompts you for the duration, there will be an option somewhere on the screen where you can click and select a different timer app.
Upvotes: 3 <issue_comment>username_5: If you're using the Google Assistant mode, when you say "ok Google set alarm", it will type your words as you speak, and then vocally respond, typing its words as it speaks, in a facsimile of a text messenger. An icon for the clock app it's currently using should appear beneath Google's response as she asks you when you would like to set it for. If you click on this, it will drop down a menu of options for which clock app you'd like to use, and then it will use this as your default alarm clock later on. I believe you may also be able to say "view alarms".

* Open Assistant.

* On that card, click the timely icon and select the default clock from the list.

Upvotes: 1 <issue_comment>username_2: I suspect this strange behaviour is caused by some setting that requires developer options to be enabled, but itself is not deactivated for instance USB debugging., transitions/animations etc.. (this has been observed to enable developer options in some LG builds typically when the battery saving feature disables animations at 15% )
As a workaround try this:
* Go to developer options, turn off debugging,
* Then disable the developer options with the switch on top of the screen
(same as your screenshot)
The trick is to first deactivate setting that uses developer options then toggle it off

Upvotes: 1 <issue_comment>username_2: as the above answerer pointed out, an app that will hibernate other apps when screen is closed like Greenify will help prevent unnecessary background services running. but if I'm not mistaken Google services cannot be controlled with Greenify and hibernated .
what you can also do it turn off mobile bandwidth usage in the background. this is a setting available on Android 6. Plus or it may even be before that I'm not sure.
it is under mobile data traffic >> restrict background data. you can restrict at phone level which did not work well for me because my phone would go to sleep for a long time and I found it hard to wake it up or you can disable at app level .This works best for me.
another option to try out is under developer options limit background process limit to nothing which means there is no background process or you can restricted to only one or two background processes

As for telling which app generated it, aside from going the hard way (installing and starting the apps one-by-one), you should also be able to use tools like MyAndroidTools to check the services and broadcast receivers an app possesses. Apps with ad SDKs will likely have services and receivers dedicated to maintaining the SDK.

2017/08/07 | 2,570 | 10,289 | <issue_start>username_0: Background
==========
"**Google Play services for Instant Apps**" has installed itself onto my device *without* my permission. It *broke* functionality of my firewall (AFWall and couple of other apps). And it is updating itself and other apps/components without permission. When I uninstall this component, it downloads itself again and installs right back. *(That is, most likely it is "Google Play services" that's actually doing this in the background)*
There are no confirmations and no notifications of anything downloading, updating, or installing. The way I discovered it was by noticing that some functionality of my apps was changed/broken. So I used an app ("System Info for Android") and it shows that in fact this "Google Play services for Instant Apps" was installed a day ago.
**My question is:** how do I completely disable unauthorized updates of an Android device, yet preserving the following functionality:
* Contacts Sync
* Google Play Store
* Google Maps App
In these screenshots, you can see that all settings responsible for automatic updates are switched off. Therefore this download and installation is clearly unauthorized and should not be happening. *The screenshot of Instant Apps setting shows up after the thing is already installed. Leaving just the global setting from Google Play Store.*
[](https://i.stack.imgur.com/n5s51.png)
*Settings › Apps* // *Settings › Google › Instant Apps* (turned OFF!) // Play Store Settings (Auto Update turned OFF!)
It has all started after I followed a *misleading suggestion*, you can see in this screenshot, to update "Google Play services":
[](https://i.stack.imgur.com/1Kwtm.png)

---
Update 1:
---------
What I've discovered so far is that *something* (most likely "Google Play Services") is requesting the download + install. The way it's doing it is placing the request with Google Download Manager. Unclear what triggers it, but if watching device closely an icon from Download Manager *does* show up in notification indicating download percentage. However, upon completion, it instantly disappears. Still, there is nothing indicating installation.
What I've tried so far:
1. Install the following as user-level instead of system-level apps that they are originally: Google Account, GP Store, and Service Framework (`com.google.android.gms`; `com.android.vending`; `com.google.android.gsf`) This didn't work. The download is still requested and subsequently, installed.
2. Seems any way of blocking installation will make it download again and again (until your data is used up). So most likely best approach would be to prevent the downloading in the first place. I wasn't able to install Download Manager as a user app, which seems the part that needs to be controlled.
3. Blocking Download Manager and/or Play Store via firewall is possible, but that breaks down the only trustworthy way of downloading apps.
Update 2:
---------
Downgrading to the previous version of GP Services (v11.3.02) worked for a few days, but today GP services for Instant Apps was downloaded and installed. So, doesn't matter which version you use. Most likely Google will update all phones this way regardless.
Update 3:
---------
So now Google is updating itself on regular basis pretty much whenever it feels like it. If I'm streaming a movie, crippling my speed, using up my internet bandwidth for which I pay money per MB. In this image you can see 3 Google apps were updated without permission.
[](https://i.stack.imgur.com/9PAkl.png)<issue_comment>username_1: As the name suggests, it's part of the Google services apps. PlayStore uses it to run apps without installing them (new service). It is possible to disable but not remove (as far as I know it will just keep installing it self as being part of the core services).
To disable, go to *Settings › Google › Instant Apps* and switch the toggle switch ([Reference](https://support.google.com/googleplay/answer/7240211)).
I believe this will be a system app on newer devices as they come out, for the rest of us with older devices they will just force install on compatible devices.
**Edit:** Due to the fact the question was amended after I answered. This answer applies to none rooted devices. With a rooted device it could be possible but I can't think of a solution that's easy or permanent.
Upvotes: 2 <issue_comment>username_2: **About:** [Root Only] This solution involves blocking write access to the temp (cache) folder where Google downloads its system apps such as Google Play Services, Google Play services for Instant Apps, etc. It's simpler than it looks, because I'm explaining everything, it looks like a lot. Afterwards, installing new apps essentially becomes 3 steps and the process is similar to installing programs on a PC.
---
**Background:** Under my system the folders work as follows:
1) `/data/data/com.android.providers.downloads/cache`
\* This is the folder where Google system updates (as well as New system apps) are installed.
\* Unfortunately, this folder is also used for downloading normal new apps. So you can't just block it permanently. You have to be able to block/unblock it when downloading new apps.
2) `/mnt/sdcard/Android/data/com.android.vending/files`
\* This folder is used to update normal (non Google-system apps). So no need to block this, or do anything special when it comes to updating your normal apps like Facebook, games etc.
---
**Solution:** The *cache* folder above is kept locked during normal operation. When you want to install a new app, overall process is as follows (although mostly automated): (1) unlock *cache* folder (2) lock app folders, in case it sneaks through while it's unblocked and installs it. (3) Download your new app from the store (4) Copy downloaded program from installation folder to another place, and rename it from default name (download.apk) (5) Clear and lock *cache* folder (6) unlock the apps folders (7) Click on the apk file to install it.
Obviously you don't want to type this at the terminal every time so these are automated steps. They involve using two additional apps as well as having BusyBox installed (to be able to use chattr command by the scripts)
1. Locking unlocking is achieved by an app called Gscript. You can use any other app that achieves execution of scripts. There's a version in google store, but it crashes for me and other people. There's a stable fork available here: <https://bitbucket.org/Equidamoid/gscript> (Thanks to author's post here: <https://stackoverflow.com/a/20328927/7609435>)
Just paste these two scripts there. (Both need SU)
A) Execute before download - **Lock apps / Unlock cache**
`chattr +i /data/data/*
chattr +i /data/data
chattr +i /data/app/*
chattr +i /data/app
chattr -i /data/data/com.android.providers.downloads/cache`
B) Execute after download is complete and after you copied the file - **clear and lock cache / unlock apps**
`rm /data/data/com.android.providers.downloads/cache/*
chattr +i /data/data/com.android.providers.downloads/cache
chattr -i /data/data/*
chattr -i /data/data
chattr -i /data/app/*
chattr -i /data/app`
2. You will know the app is downloaded when the Play Store says "download failed". It'll say that because it couldn't install the apk, but it was actually successful downloading and it is sitting inside the *cache* folder. Before running script (B) above, you have to move the file from *cache* folder elsewhere. You can do it using any app of course, but I like to use Total Commander, because it can have two panes and it supports bookmarks (I added *cache* to it). So move it and rename the file from default name to something else and then run the (B) script above. Also note, when copying the APK it should have an icon of the app. If it has the default icon it's probably corrupt download due to other unrelated reasons, so you can try downloading again.
3. Now the *cache* folder is cleared and locked and apps folders are unlocked. *(you can double check that cache folder is empty just to be 100% sure but I doubt this is necessary)* You can now install the APK you downloaded.
**Note1:** If you click on a new download and it says "pending" just (force) close Google Play and restart it, it should start downloading automatically.
**Note2:** I have tested this with only Android: 6.0.1 / MIUI: 8.5.3.0 so this solution might not be universal. Check to see if you have the cache folder and if the download of the Google Play Services is being uploaded there (once upload is finished it stays there for a while).
**WARNING:** It's fine to keep cache folder locked up, but if you happen to restart your phone while those data folders are locked, your phone will not boot. And you'll need to go manually and change it from TWRP shell.
P.S. I understand this solution is not for everyone, but if your primary concern is stability and to keep data-usage under control, this works... for now. Hopefully someone will come up with a better answer than this.

In the best case scenario this should be enough to block Instant Apps from auto-updating.
Run on device via a terminal (connectbot, juicessh, etc).
```
pm hide com.google.android.instantapps.supervisor
```
Or, if running via adb on a pc while connected via cable (or wifi adb), then use:
```
adb shell pm hide com.google.android.instantapps.supervisor
```
Unlike `pm disable` *`pm hide`* also works on non-rooted devices. So far, I didn't see any more Instant Apps notifications appearing.
If the above does not work for you then another approach would be modifying the SELinux context of the file/folder (e.g. with [`chcon`](http://www.all-things-android.com/content/se-android-commands)).

To revert the `pm hide` command above use:
```
pm unhide com.google.android.instantapps.supervisor

2017/08/07 | 577 | 2,307 | <issue_start>username_0: I have been using google maps for a while now as my driving guidance/maps app. It does have one slight inconvenient, while you are driving you'll get all notifications to still crop up space on your screen, and for some apps they might even get in the way of your maps.
Is there a way to keep google maps, or any other maps app for that matter, foremost on my screen?
If I set the phone in driving mode, can I stop other apps from getting screen space/time all at once or is it in a per app basis?<issue_comment>username_1: Use **[Android Auto](https://play.google.com/store/apps/details?id=com.google.android.projection.gearhead)**.
This will reduce the accessing time for Maps or Any other application required while driving.
Also During driving and using android auto, you'll have a better experience of Map as the notifications from other apps won't bother you as they do on running the Maps app directly.
Reason for this is to minimize the interruption of other apps while driving.
Android auto is designed with keeping these points in mind and to make driving safer.

The option for me is in "Settings", "Security", "Screen pinning", which you set to "on". You pin an app by swiping up on it from the overview list, then clicking the "pin" icon which will appear. To unpin a pinned app, press and hold the "back" and "overview" buttons at the same time.

This way you will not receive any notifications while you are using the Maps app and there will not be any interruptions and you can access all your notifications once your travel is over. Alternately, you can download offline maps in Google and switch off your internet completely. This way you will not only receive any notifications, but your battery will also be saved if you are travelling for a long time.

So try this:
* Navigate to the platform tools folder (`%USERPROFILE%\AppData\Android\Android-sdk\Platform tools\`)
* Open command-prompt (or teminal) by right click + shift
* Disconnect any USB cables and close other instances of emulator devices.
* Now try `adb devices` and make sure it lists the emulator device and is not blank.
*Note: If this fails first run `adb kill-server`*
* Now run `adb root` command
* Root your virtual device [as per instructions](https://stackoverflow.com/a/44473415/7551330)

2017/08/09 | 2,911 | 11,508 | <issue_start>username_0: Android 5 offers two encryption features:
1. Encrypt the device (phone)
2. Encrypt the external micro SD card
I understand the benefit of 2.: if someone takes my micro SD out and wants to use it on another phone/computer, he won't be able to see my personal files.
But I don't see the the benefit of 1. over a simple password screen lock: nobody can take the *internal* memory of my phone out of the phone itself. So what is the advantage of 1. over a simple screen lock with password + SIM code lock?
**In which precise situation would a thief be defeated by an encrypted device whereas he wouldn't be with a standard screen lock with password?**
(I'm not speaking about external micro SD for which I already understand the benefit of encryption)
To be more precise: is there a way for a thief of a phone *with* password screen lock *but no device encryption* to access the phone's internal data (let's say he doesn't know the password / cannot crack it).<issue_comment>username_1: >

Understand that encryption is used to protect the data from unauthorized access (device misplaced or lost or alike situations). If you are sure that the device would not fall into wrong hands ever, you don't need the encryption.
As for the quoted text: some devices have their bootloader unlocked; some others don't even have this concept (such as MTK devices) in which case a custom recovery (a bare-bone OS) can be loaded into the Android device which would grant complete *unrestricted* access to your data if it was not encrypted.
Alternatively, if a PC has access to your device through ADB (think of Android versions prior to JB) than your data is available to that as well.
Some might even go as far as taking out the emmc or the type of storage in your SoC and use it somewhere else. What would your screen lock do if Android is not booted into? Nothing!

A custom recovery now cannot gives access to your data since it remains encrypted. The thief however can brute force the encrypted partition. Depending upon the power of the machine(s) they've got they *may* be able to find the key to decrypt the data.
Upvotes: 5 <issue_comment>username_2: You are right that there is no advantage of encryption if your device screen lock password can be cracked or guessed by an intruder. The moment he / she does that , there is no security offered by device encryption - *Physical possession is ownership* and you are compromised
Reason behind this is that Android didn't separately use a password for Disk encryption and lock screen. Lock screen is a part of encryption process. This is a security concern that seems to be overlooked in favour of making life easy for an average user

If you want to keep the encryption password separate from the lock screen password you can use this app [cryptfs password](https://play.google.com/store/apps/details?id=org.nick.cryptfs.passwdmanager) developed by the same person whose text has been quoted above
**Edit**
In response to the edit in question, you are reasonably secure if a thief cannot crack or guess your password. But I understand that there are methods available for a sophisticated thief who is technically advanced to compromise your data security (some have been hinted by username_1's answer )
Upvotes: 2 <issue_comment>username_3: Why encrypt the device?
The main and ultimate reason is for **the safety of your personal data**. Even if it's not immortal, it can protect you against most "garage workshop" level of intrusion.
First, *~~Physical possession is ownership~~* is wrong. What's the intention for a lock screen (with password prompt)? Yes, it's to prevent unauthorized **normal** access to a device (originally computer). However, as the age goes, people have learnt to *bypass* the lock screen by booting into another separate operating system and then they'll gain access to everything. The intrusion technology has evolved by a lot ever since. Does the computer refuse to boot into an alternative system? No problem. Take the drive and grab another computer.
That's the origin of data encryption. When a simple password, there's hardly any difficulty to bypass the protection. If any datum is encrypted, it won't be accessible without the correct key. With a good encryption algorithm, brute-force attack is confidently impratical. No one wants to crack some data for tens of years. It has helped a lot with data security.
Encryption is intended as an add-on protection. In other words, it's not a poka-yoke (aka foolproof). If someone keeps on telling others his lockscreen password, or he hasn't set a LS PW at all, the encryption can do... pretty nothing. When you meet an extremely malicious guy, he can steal your phone and pick off the storage chip, ano use another device to extract data. In that case nothing is effective except physical encryption.
The downsides are
* primarily, performance degradation
* encryption key gets messed up (rare case but...)
---
Why not encryption? Don't you store very private photos that you don't want to leak?

While taking out your phone's internal storage out is harder than the SD card, it's definitely not impossible. Rework stations used to extract chips from circuit boards may be expensive, but not outrageously so (around $1000), and can be rented in many electronic repair shops for tens of $ an hour.
[](https://i.stack.imgur.com/LG1hD.jpg)
If you have a bunch of stolen phones you've decided to destroy in hopes to get sensitive data (older models you won't be selling anyway), it will cost you a couple of bucks per phone to get the flash chip out.
Reading the flash IC is even easier. Check out this [flash reader](http://www.flash-extractor.com/shop/), which can be bought for under $300 (and about 10 times cheaper on e-bay or aliexpress):
[](https://i.stack.imgur.com/RdTPW.gif)
BGA versions of such flash readers are available as well. One of the side-effects of flash memory becoming so inexpensive and omnipresent is a very high level of standardization, to the point where chips from different manufacturers not only have the same physical size and pinout, but also support the same command set.
Upvotes: 5 <issue_comment>username_5: Well actually... Although it might seem like your data is safe without encryption and with a screen password, the reality is that it's vulnerable to root based exploits.
The device is **compromised** in the sense that it is accessible via adb or a USB exploit.
With *full device* encryption, the data is completely impossible to get to as the screen lock is required at start up.
What this means basically, is that if you have FDE your data is inaccessible without the password while without it, your data is accessible to a smart hacker.
Upvotes: 1 <issue_comment>username_6: No password/lock/pincode implemented without encryption can protect your data when attacker has physical access to device. Because there is always (yes always) a way to alter these locks. But when there is encryption, altering doesn't work because data remains scrambled until password is found. (Or cipher cracked, but this is very very unlikely to happen when cipher is strong)

[They don't need to.](https://www.youtube.com/watch?v=tM66GWrwbsY) There's literally YouTube videos about how to do this. Any average person with dedication could do this. Any thief that's made it their life work will thank you for not encrypting your phone, because it'll reduce their effort to mere "minutes" instead of "hours".
We're not living in the Stone Age. This is the age of prolific technology everywhere. If you're not using full drive encryption on your phone, laptop, etc, then your data is very easily accessible. Yes, there is a minor performance penalty for encrypting your phone, and some minor inconvenience, but using encryption is a *major* inconvenience to those that might gain access to your phone for a short period of time, like an hour or even overnight.
While some critical information is encrypted (typically passwords, PINs, and the like), most of your data is opaque, and can be used to commit all sorts of Bad Things™ with that data. By using full device encryption and a secure password, you avoid being a casual victim.
No security is absolutely perfect, but using a PIN instead of encryption is only protecting the "front door" of your system. Many phones can be accessed through back doors, such as SSH servers, safe mode kernels, and more. Many devices simply do not get security "right." Full device encryption helps bridge that gap in security.
There are still some risky, but theoretically successful attacks you can do against encryption, but those are still outside the reach of casual thieves. Phones without encryption, however, can be broken in by anyone that actually bothers to get a hold of your phone with the intent to get your data. Phones with encryption are usually only good for one thing: reselling on the black market. In many cases, your data is far more valuable than the device itself.

1. Go to Setting-> Apps
2. Tap on Joy Launcher
inside joy launcher, select uninstall updates then, select storage and clear data,it will work 100%
Upvotes: 0 <issue_comment>username_8: Yeah Alcatel really screwed up a lot of the factory apps. IDK who the dev is now but they need to fire him or her. To return joy launcher to the factory version (which is called onetouch) go to settings, apps, and scroll down to Joy launcher. Go ahead and click it then in the upper right hand corner there are three dots. Push the dots (menu) and uncheck the box to uninstall updates. That will bring it back to the way you bought it. Make sure you disable the automatic updates for Joy Launcher aka Onetouch. Hope this helps you.

*I am open for rooting, installing custom ROMs and using external equipment like headphones.*<issue_comment>username_1: From what I read, it can receive phone calls. So, I assume there's a Phone app?

I suggest using Skype or Google Voice to call landlines, or Google Duo to call other Android users. Both of these options will route your call over data.

I'm trying to restore my apps that are backed up to Drive. I keep getting this (screenshot) and cannot change so I can restore my apps. I even did a factory reset and was not offered the option to restore my apps. I don't have any idea what was done to make it return this now about the admin. It's my personal phone and nobody else uses it. I don't have a school or business account either which is where the help tells you to go and change admin.
Any help please there to resolve this.

Upvotes: 3 <issue_comment>username_2: Gave an answer but it says the answer already exists yet answers said it's a false alarm. Problem is it's not false for every user as some show there are no backups and someone else reset their device but couldn't restore because it said there are no backups. It is a false alarm for some but not all. So users need to double check that a backup actually exists.

```
tsu -e

The option `-e` preserves your environment, and should be enough to run your script without errors.
Also note that `tsu` is just like Linux `su`, which opens **another shell** instead of running a command.

```
/data/data/com.termux/files/usr/bin/tsu -c '/data/data/com.termux/files/usr/bin/php /data/data/com.termux/files/usr/bin/vkup.php'

2017/08/11 | 627 | 2,383 | <issue_start>username_0: Some of my more secure applications offer fingerprint unlocking. This would be convenient to use, and I don't foresee any security issues with someone using my fingerprint because I would have had to have unlocked the phone with a pattern for someone to gain access to the application.
On the other hand, if the phone can be unlocked with my fingerprint as well, someone could unlock it while I am incapacitated (e.g. sleeping) without my knowledge, and then unlock the high-security applications as well. Having a pattern is a great form of two-factor authentication IMO.
I added a fingerprint to my rooted phone which runs LineageOS 14.1, Android version 7.1.1 -- this automatically allowed unlocking the phone via fingerprint. I cannot find a setting to disable this without removing the fingerprint and being unable to use it in any of my apps. Is there any way I can forcefully disable fingerprint authentication on the lock screen, but retain access to fingerprint unlocking for various apps without using a custom lock screen?
Here are the options I have for the lock screen and fingerprints -- I do not see any way to disable fingerprint authentication without removing the fingerprint, from the settings at least:

Be very careful! Upgrading the firmware on an op3 will make the TPM destroy the encrypted private key used for decryption if the bootloader is unlocked so if you're encrypted it is a good idea to backup all data before you attempt to upgrade the firmware
There is also a high chance that your older recovery will no longer boot after upgrading the firmware so you must upgrade your recovery before you attempt an upgrade

2017/08/14 | 849 | 3,219 | <issue_start>username_0: When I was young, memory and RAM were the same, but now they seems to be different (this is called progress).
But what exactly is the difference in modern smartphones?
What is (free) RAM and when is (free) RAM important?
How can I help it as a user?<issue_comment>username_1: "Memory" is a vague term. It can refer to the *RAM* (the memory programs use while they're running) or to the *storage* (where things are saved). The storage is the equivalent of a hard disk on your PC, but it's not actually a hard disk, it's Flash memory.
You need free *storage* to install new apps or download music, videos, etc. If you run out of storage, you might need to free up some yourself by uninstalling apps or deleting downloaded files.
You need free *RAM* to run more apps, but this is managed by Android. When an app runs, it starts using RAM, but when you stop using it (back out of it, or switch to another app), Android doesn't remove it from RAM right away. This way, the app starts faster next time you run it, because it doesn't need to load everything from storage again. But when all the RAM is full, Android will remove apps that you haven't used in a while. Next time you start those apps, they'll be loaded from storage.
Normally you don't need to worry about how much free RAM you have, because Android manages it.

In Computer Science, **memory** is a wide concept for *everything that is capable of storing data*, while **RAM** only stands for *Random Access Memory*, or more precisely, *runtime memory*.
**Memory** is the same word that the M stands for in both acronyms ROM and RAM. It's simply because both of them can store data, despite one being non-volatile and the other being volatile.
These concepts haven't changed even if you're talking about modern smartphones.
Fore more information, see [Are there guidelines on how much free RAM a phone should have?](https://android.stackexchange.com/q/20032/205764) and our [tag wiki for `ram`](https://android.stackexchange.com/tags/ram/info)
>
> *What* is (free) *RAM* and when is (free) RAM important?
>
>
>
Whenever a process runs, it requires RAM to store is runtime data. When many processes run together, they demand more RAM. You should never make your phone's RAM full, so a portion of its RAM is available for use when a process requests more. That "available for use" RAM is called **free RAM** (or more precisely, "*available* RAM").
Free RAM is always important, but it is often **more important** when you're trying to start another app or running a resource-intensive app. It is because when there isn't enough RAM, some processes may fail, and resource-intensive apps will refuse to run.

If you're using a moderately new phone, leave it alone because Android can handle it very well. Stay away from "RAM cleaner"s and "Task Killer"s as they do no help actually.
If you're using an old phone with 256 MB or so of RAM running Android 2.x, you should install less apps and routinely terminate them, ~~or throw it away and buy a new phone~~.

I also do not see it listed in our MDM software, so I can't force a remote wipe that way. It appears that it could be wiped with a Google account, but I do not know what Google account it may have been linked to. Is there a way to expose which Google account it was attached to in the hopes it's one we have access to? Or is there a way to totally reset it to factory and wipe the data?<issue_comment>username_1: There are two possible ways from here:
1. Hard Reset: This will wipe all data stored on the phone, [see this](https://www.androidcentral.com/how-factory-reset-android-phone#buttons) on how to perform a hard reset using hardware buttons.
2. Try something like [Dr.Phone](https://drfone.wondershare.com/unlock/reset-locked-android-phone.html#part2) software to remove screen lock.
Upvotes: 1 <issue_comment>username_2: Here's the trick, when you hard reset your android device, one would want to believe that all the personal information are completely deleted and safe from any other user of the device. But far from it, even after the **hard reset**, some data which might include personal data, still remains accessible on the local storage.
Even after **hard resetting** the device, all the data remains present phone memory and can be easily recovered with any good `data-recovery tool`. Therefore if you should just do a simple **Hard reset** or **Factory rest** as the case might be, and another user gets his/her hands on the device, they can easily recover most of the personal data of the previous user using a **`data-recovery tool`**.
To fully wipe your personal data from any android device, try the steps below;
Encrypt the android device before Hard resetting it
===================================================
Encrypting the device before hard resetting will disorganize or scramble the data on the device, making it almost impossible for whoever that will want to recover the data using any `data-recovering tool`, because he/she will have to provide a specific key to organize or unscramble the data.
To encrypt the device, click on your **menu list** => **settings** => **Security** => **Encrypt phone** ensure that the device is connected to a charger to prevent any lost of data, then you finally click on **Encrypt phone**, sit back for a while and wait for it to encrypt completely.
Factory Reset the Android device
================================
When you've successfully encrypted the device data, the next thing to do is to Factory reset the device, but **NOTE** This will erase all of the data on the device, but in your case, you're aware of that already.
To Factory Reset the device, click on your **menu list** => **Settings** => **Backup and reset** from here, you should see the **Google account** attached to to the device, but to still continue with the resetting, click **Factory data reset** which usually should be at the end. => **Reset phone** or **Reset device**.
Ensure you have adequate charge on your battery to handle the entire process and that battery is not mistakenly pulled off during the process, because if any happens, it can lead to corrupting of data.
---
>
> To be on the safer side to add another layer of protection, you can do these again to prevent any **MINAMOTO** individual from doing any funny thing
>
>
>
---
Load any dummy data
===================
Following the 1st and 2nd steps should be enough for most people, but as I said to be safer, load fake data on the device again, you can connect your phone to a PC and copy/paste large files maybe videos, enough to fill/or almost fill all the space.
Redo the 2nd step (Factory Reset the Android device)
====================================================
Carry on another factory reset, this should erase the dummy content you loaded onto the device. This will make it even harder for any other user of the device to locate your data because it will be buried below the dummy content.
I hope these helps.

What about Android? It seems like Android 6.0.1 is still totally missing IPv6 on the tethering side. Not only that, but tethering explicitly doesn't even work at all when you're on an IPv6-only network, unless your phone has IPv4 connectivity, too (which with DNS64 and NAT64, is often not the case -- T-Mobile US is especially well-known for not being keen on providing native IPv4 to IPv6-capable devices).
Has IPv6 tethering support been added since then? Are there any plans to add support in later versions? It's 2017, there are basically no more IPv4 addresses, what's up with this disappearing tethering support?!<issue_comment>username_1: It should be available since Android 7. <https://android.googlesource.com/platform/frameworks/base/+/7747fd4/services/core/java/com/android/server/connectivity/tethering/IPv6TetheringCoordinator.java>
It's working on my Android 8.1.

```
% ifconfig en0
en0: flags=8863 mtu 1500
ether 8c:29:XX:XX:XX:XX
inet6 fe80::8e29:XXff:feXX:XXXX%en0 prefixlen 64 scopeid 0x4
inet 192.168.43.163 netmask 0xffffff00 broadcast 192.168.43.255
inet6 2607:fb90:4bYY:YYYY:8e29:XXff:feXX:XXXX prefixlen 64 autoconf
inet6 2607:fb90:4bYY:YYYY:d427:13ba:ZZZZ:ZZZZ prefixlen 64 autoconf temporary
nd6 options=1
media: autoselect
status: active
```
Note that this includes both a temporary random IPv6 address (used ZZ to anonymise), as well as the permanent IPv6 address that's deterministic based on the prefix (YY) and the MAC address (XX).
P.S. Yes, it does appear that T-Mobile US might as well be delegating the whole /64 prefix to its ME, however, doing a [`traceroute6(8)`](http://mdoc.su/-/traceroute.8) may indicate that the prefix is not actually fully dedicated to the Mobile Equipment, as the first use of the prefix appears to be at the PGW level, followed by ME, followed by OS X, when doing a traceroute6 to the permanent IPv6 address of the OS X box:
```

Still pretty cool to be getting not just one but even two public routable IP addresses on a laptop whilst tethered to an average Android device with default everything; like the internet was meant to be, p2p.

2017/08/16 | 1,155 | 2,981 | <issue_start>username_0: Sometimes I want to edit text files on a remote computer (such as linux scripts, websites, etc.) but I only have an Android device at hands (let's say I'm sitting in a train and have nothing better to do with my time).
I could download the files over SSH, edit them, and upload them again, or even edit them on the SSH console, but this is tedious (I mean MORE tedious than it already is to edit text with an handheld device, if that is possible).
Is there a way that I can directly edit the files remotely? I would envision a solution that might, for example, automatically download the file, and upload it back on save.<issue_comment>username_1: It should be available since Android 7. <https://android.googlesource.com/platform/frameworks/base/+/7747fd4/services/core/java/com/android/server/connectivity/tethering/IPv6TetheringCoordinator.java>

2017/08/17 | 1,312 | 3,341 | <issue_start>username_0: I recently started using an Oppo A77 phone and have no experience with ColorOs. All I am trying to do is to be able to display a preview (sender/subject/body/something) show up on my notification window where Gmails notifications come up. There is no option to select preview messages in the notifications settings.
This is my notification setting for gmail:
[](https://i.stack.imgur.com/AKPXv.png)
and this is how my gmail notifications come up:
[](https://i.stack.imgur.com/XtcQC.png)
How do I get a preview of my gmail notifications on an oppo A77 ?
This is the exact question asked on other sites and no one seems to know the answer :

2017/08/18 | 513 | 1,938 | <issue_start>username_0: I have an image on my smartphone and I want to paste it into Google Image Search to see if I can get similar images.
I can do this by pasting the image using desktop but not using Android ...
Is there such a possibility?<issue_comment>username_1: Steps for reverse image search from a smartphone:
1. Click [here](https://ctrlq.org/google/images/) to visit Ctrlq.org.
2. There you will find Reverse Image Search option (Google's official) and within there you will see the *Upload* button. (It will allow to choose from camera and gallery.) Click on it and select an image.
This will search and display to you related images on your mobile phone.

This app lets you pick an image from your gallery (or take a new one with your camera), perform some basic editing (crop/rotate), and then fires a corresponding search for similar images.
The list initially linked (disclaimer: link goes to my own site) gives you some alternatives.
