问:
Is it possible to whitelist an app from Google Play Store?
It's actually not a big problem, but annoys my eyes when I usually intend to update some apps.

From the screenshot above, you see a name of an app and beside the name there's a warning sign and it said my device is at risk, though I believe that app is perfectly fine and there's nothing wrong with it.

This is when I tap the "See details":

There's also this setting:

I did turn on/off, and this is what happened if I turn it off:

Is it possible to remove that annoying notification by putting the app in a white list or something so that Play Protect wouldn't scan and would skip the app?

To simulate the goal I want, I backed up the app and uninstalled it:

And I want to be like this:

Is it possible to do this without uninstaling the app, but just whitelist the app from Play Protect?

Edit :

I just remembered that this would also happen when I re-signature an app by any tools that resign the original app from where it's originally obtained.

For instance, I downloaded an app from play store, back up the apk file and resign it this would happen and when installing it, there would be this notification:

But the app that I make an example above is the original app (I guess). Also, if I press 1) OK, Play Protect would do the job and the app wouldn't be able to be installed, but if I press 2) Install anyway (unsafe) (though actually there's no something wrong, so I think it's safe), the app would be successfully installed as normal.

My phone has slowed down after inserting an SD card (Strontium 32GB 85 MB/s UHS-1 CLASS 10 card)
I have no idea why. the card is empty(except the empty folders made by android). The lag is most pronounced while multitasking(for example duo video call in picture in picture mode while i message someone on messenger) but still exists while opening other apps when not multitasking. When i entered the SD card it asked me if i want to use it as extended storage or portable and i chose portable. It lagged so much at that time. It's a Realme 7 with Mediatek G95 and UFS 2.1 storage + 6 gb ram. i also have a custom rom installed on it called CorvusOS.

How does one clear the storage in Google One without affecting the original files?
I was trying to move all my stuff from my old iPhone to my new google pixel 6 pro. In the process of me trying to do, that one of the attempts I made was to use Google One to make this change. It failed as I outlined in that question but it also had the unexpected consequence that now it seems things like my g-drive are overfull of data I didn't even know was sent to them (I mean why the hell were files sent to my g-drive?!?!?! it just feels like an attempt to google to force me to use their google one thing I don't want or need).

Anyway, now that I want to remove everything from google one I can't figure out how to do it without affecting the original files e.g. in my phone.

Is there a way to remove everything on Google one without affecting the original files?

sample instructions are not clear if they will affect

```<code>Manage storage on your computer
On your computer, go to Google One.
Under "Clean up space," click View.
Under the category you want to manage, click Review and free.
Select the files you want to remove.
To sort files, at the top right, use the filters. You can’t sort some categories.
To preview files before you delete them, click the photos, videos, and certain emails.
After you select your files, at the top, click Delete "".
To confirm, click Permanently delete.
</code>```

If I try it look what it says:

```<code>Move 1 item to Trash?
This action permanently deletes selected files after 60 days.
Deleting these items will remove them from your Google account, synced devices, and shares within Google Photos.
</code>```

Ultimately what I want is as if I never had used google one. ever.

How to know if an app doesn't work because my phone doesn't support or it's just the app's fault?
When the internal storage (not the SD Card) in my phone is almost full, sometimes it makes some apps failed to be installed, but they will be able to be installed after I free up some space.

I installed three different apps today and they are from different developers, but they have the very similar behaviour when they're crashed. So, I concluded that my phone might have been broken or something. The apps can be normally accessed, but they will crash and force closed, the errors can't also be reported, I'm not sure.  I don't know whether my phone doesn't support the apps or it's just the apps that don't function well. I bought the phone 7 months ago, and I think it's unlikely that it's broken already.

How to know if it has something to do with the storage or some settings I don't understand perhaps? The app version, minimun SDK, minimum or maximum android requirements or whatever.

copy play services from one device to another
I have an Android device (fire tablet) without playstore/playservices. By googling, I found tons of howtos to download and install the 4 necessary apk packages. Since I have several "offcial google" devices, I thought if it isn't possible to just download the apks from one of them, so I don't have to read a lot to find our which download source is trustable.

While I know how to list all installed packages and also how to adb pull them, I only found

com.google.android.gsf

com.google.android.gms

com.android.vending
but not com.google.android.gsf.login in the list retured by pm list packages.

Chrome (Android) auto download pdf every week (is it a virus ?)
A year ago i've been fighting against an hacker that had access to a lot of my accounts (not very difficult since my passwords were record with google account). Somehow he archives to get the codes from 2FA on my phone. I guess he had infected my phone as well (dunno if he infected my PC or my phone first and if he archieve to infect both threw one). I decided to reinstall android. Now as a 2FA i'm using authenticator app from google. Since that time, I also reinstall windows on my PC to be 100% safe. I obviously changed all my passwords since that time, multiple times.

I received a month ago an alert from microsoft saying that someone break in (again). So I changed the passwords (again). Im weakly checking connexions. Hackers are still trying but for now they just could not break the password.

But more recently, I've notice chrome app autodownloading a PDF once or two a week. I dont have any tab open to the domain where it comes from, it never ask where i want to store the file even when I enable this parameters. The file is called reaching-all-learners.pdf and come from this link : https://education-static.apple.com/product/reaching-all-learners.pdf
BE CAREFUL ABOUT THE LINK since I dont really know what is the matter with this site and how legit it is or not.

I'm wondering if any of you, with cyber knowledge could tell me what is going on and how I can fix it so it stop download this file again and over again.

My old phone can't detect my new phone

The phones are right next to each other. Both are connected to the same Wi-Fi network. Even in these ideal circumstances, the old phone does not see the new one in Settings → Google → Set up and restore → Set up nearby device. It just says "Searching for devices" for about a minute before reporting "No devices found". What else do I need to do to sync the old phone to the new one?

It's not the same issue as this one because there are different Android versions involved.

Using a VPN Server on Android device in order to perform remote vulnerability scan
I am working on an Android Java application that performs a vulnerability scan of the network where the mobile device is. Since I cannot install any type of vulnerability scan tool on Android I would like to send the vulnerability scan packets from a back-end server (running open-vas) to my android device and then make the android device forward them to the destination hosts inside his network. The easiest way to do that would be to create a VPN Server on the android device, but I don't think it's possible with the VpnService APIs. From what I have found it looks like someone managed to forward traffic with VPN Service: Android VpnService - How to forward intercepted internet traffic.

Another idea was to create a sort of packet wrapping: I can wrap the original packet coming from the back-end server inside a standard TCP packet, send it to the android device, unwrap it and forward it to the host inside the device's network. Although I don't know if this would really work in my case for 2 main reasons:

I will probably receive RAW packets from the server (since vulnerability scanners forges specific RAW packets for vulnerability testing) and Java does not have any support for manipulating packets

Even if I am able to unwrap the packet I will still have a RAW
packet to send and from what I have seen Java does not have any
support for RAW sockets for security reasons.

So do you guys have an idea if there is a way to create a VPN Server on Android to do this remote vulnerability scan?

Thanks!

PS Maybe rooting the device will give some more alternatives but I am reserving this as last chance.

问:
how to force an old app to be supported in the higher android version than it's supposed to be?
I have a very almost similar question to this discussion: Is it possible to run old apps on newer versions of Android? If so, how?, the question in the discussion hasn't even got answered officially yet, so I don't think it's duplicated.

Besides my question more want to ask about the possibility if the app that used to work in my previous android version i.e Android 11 and after updating my phone to 12, the app that used to work, doesn't work anymore.

The app that I'm talking about is "Stack Exchange" i.e. the android app version of this very site and has loads of similar features to this site. Sadly, however, the app doesn't seem to have the older or the latest version and it's even rare and not listed in Play store, mind you the app used to be in Play Store, but I don't know why they removed it, the app itself doesn't seem to be dangerous and it helped me a lot to even ask, answer, pose questions and getting notifications. This is the link of the app if it matters: Stack Exchange.

I'm not a developer, so if you explain rather complicated things I'm afraid I wouldn't understand. However if it's just a small edit using apktool, apkeditor I would probably understand.

Is it possible to make this app functions again as usual using small tricks? Or at least tell me why this is happening. I mean, I have another old app that worked in my previous android version (11), but is still also working now. Why only this app that doesn't work? What's the issue?

I also have collected all possible duplicates that after I read they apparently are not relevant.

I honestly think there's still hope to use this app after reading Robert's comment in this discussion: How to use an old version of an app that wants to get updated. Also: How to use an older version of an application?

问:
Is there any app cloner that 100% works on android 12?

I used app cloner when my OS was android 11 and it worked very well, now mine is 12 and I have installed all possible apps that I could think of to just clone an app. It's a very simple task, but I'm really disappointed none of them works well without crashing.

The only one that "almost" works is the app in the picture above, app cloner. When I said "almost", that means the app can be opened, but when I touch/tap a certain button in the app, it force closed and there's an error notification from the app cloner. The reason I like this app, because it could allow the user to install two or more (if it's premium) apps with the different version of the very same app which, AFAIK there's no app other than this that could do so.

I don't need a virtual space or any app cloners that just duplicate the main app I want to duplicate, what I want is an app cloner (just like app cloner that I'm talking about) that is able to duplicate "an apk" file i.e. the apk file that hasn't been installed and the most important part is the apk file might have different version from the original app that has been installed.

Is there any app such like that to do this? Or even is there a way, a very simple way to clone app with different version on android 12 without crashing? I read somewhere that this OS version android 12 has clone profile or whatever, I'm not sure what that is, and I couldn't find the article, if in case it has something to do with the cloning app, I would also hope you mention that in your answer.

Thanks in advance!

P.s. I might just install this app in my virtual android emulator if there's no solution for this, but I hope you could give good news that it's still possible to clone an app with different version in this OS.

How to save data/settings of OS in termux?
Short story.

Installed termux, installed Ubuntu 20.04 using Andronix,

```<code>curl https://raw.githubusercontent.com/AndronixApp/AndronixOrigin/master/repo-fix.sh > repo.sh && chmod +x repo.sh && bash repo.sh && pkg update -y && pkg install wget curl proot tar -y && wget https://raw.githubusercontent.com/AndronixApp/AndronixOrigin/master/Installer/Ubuntu20/ubuntu20-lxde.sh -O ubuntu20-lxde.sh && chmod +x ubuntu20-lxde.sh && bash ubuntu20-lxde.sh
</code>```

, installed all the modules I needed to work. It took several hours to install and configure. I even screwed in the latest version of Nodejs, which was not very difficult to do but took a lot of time.

Then I disabled VNC Viewer, exited termux. When I decided to try to start my OS, I launched Termux, made ./start-ubuntu20.sh and instead of starting it, it started reinstalling the OS for me.

I just don't understand this point because I'm already tired of trying to install. I need a mobile linux solution on a smartphone.

Termux used the latest version on Android 7. Before installing the OS, I did apt update AND apt upgrade

What did I do wrong? Or what did I forget to do? Or what did I accidentally do that was not necessary? Or maybe Termux just doesn't save the configured OS somewhere to a file and needs to be worked with on the fly (until the next shutdown?) Or maybe the problem is in my Android 7?

Also, is there an easier and more reliable way to deploy an OS that will keep all my settings? Don't know.

External SSD drive can only be detected when Android is on 100% battery
Android 11 will communicate with the external drive using a -y- connector, one lead to power, and the other lead to PNY 1TB drive.

However, once the battery drains below 100 percent, Android refuses to acknowledge the connection to an external drive unless the drive has been connected at one hundred percent battery charge. Unplug the external drive while the battery is below one hundred percent charge and you are forced to wait until the battery is charged to one hundred percent before you can reconnect to the aforementioned drive.

That being said, I am able to connect -y- cable to Android and to the external drive as long as the battery is charged to one hundred percent, establish a connection to the drive and then unplug the power lead and remain connected to the drive until the battery is drained.

问:
How can I prevent an application from closing in the background on Android 12?
I have a Pixel 6, and have the application "Fate/Grand Order" installed. On an earlier version of Android 12, the game would remain opened in the background, when the application was switched. That means, when I returned to it after e.g. looking something up on Chrome, the game would remain loaded, ready to proceed.

However, after updating Android 12 (not the game itself), the application would immediately close when switching to a different application. Returning to the game will cause it to start from the beginning.

How can I force Android to keep the game loaded in the background?

What I've tried

I have read in several sources that setting an app's battery usage to "Unrestricted" will cause the application to remain open in the background. I tried that, but the behavior did not change.

For information, my Pixel 6 has 8GB of RAM, and the developer options show that only 4.8 GB are used on average. So I highly doubt that the application is being closed out of a lack of RAM. Furthermore, Fate/Grand Order only requires 242 MB of RAM, while Chrome needs 337 MB.

Create boot.img from compiled kernel
I am trying to install Magisk on a RePhone. The only operating system related download I found (on the company's website or anywhere else) is this: https://myrephone.com/opensource.7z

That seems to be the kernel source, so if I understand it right, that should be roughly what I need to obtain boot.img. I have compiled an Android system before and afterwards the file just existed and I could use it, but here it doesn't. Is it possible to create that file from the compiled result? If yes, how?

Some more background: Not much development work seems to have been done on this phone model so far, so I can't just install LineageOS or TWRP. The stock recovery doesn't allow full ADB, only sideloading, so I can't run arbitrary commands on the phone, like extracting boot.img from it. The bootloader is unlocked.

Google activity showing things I didn't do
I have a Galaxy  S10 Lite and I need some help because I really don't know what to do about this. I have looked up for a solution and can't find one anywhere. Since I got my phone last year I have had 2 Google accounts on my phone. Well some how the Google account activity was showing I was doing things that I was indeed not doing. Problem was it shows it came straight from my phone but the times it says I was doing those activities, I know for a fact that I was not. So I ended up deleting both accounts and made a whole new account and completely removed my old accounts.

Well now it's the same thing with the new account and it's showing I'm making phone calls and doing other stuff at 2 and 3 am when I know I'm not. And today I got a notification on my phone saying someone tried to log in to one of my old accounts even though they were suppose to be deleted because they got deleted. But the old account is showing all my activity I currently actually have on my phone with my new account. I really don't know what's going on and all the activity says it came from my phone but I know I haven't done any of it. Can anyone help me figure out what's going on here or know someone who has technology experience that can help with this? Google support is no help whatsoever.

Below is a screenshot from today where it shows someone tried to login to one of my old accounts.

Country code issue on texts
Running Pixel 6 Pro & Android 12....

Since returning back to Australia from a New Zealand holiday (country code 64), I'm now finding that all my incoming Messenger texts are unrecognised as known contacts. If I try and make a contact entry directly from the text, I can see the number (and all others) are now prefixed with 64.

Phone won't receive MMS from one specific number after switching carriers
I don't suspect this is an Android specific problem, but I don't think there's another more relevant Stack Exchange.

I switched my carrier from Verzion to Google Fi and took my phone number with me, new SIM card. Ever since the move, for one specific contact I don't receive MMS messages (group chats or photos) from them. I can receive SMS/texts from them no problem. I can receive MMS from every other number (that I'm aware of) no problem as well.

Does anyone have any ideas why this would be the case? Sender uses Android as do I. They are not on Google Fi, I think T-Mobile.

Family tablet : too opened accesses for everyone
We used to have an old tablet, using an older version of Android, where multiple user profiles were allowed, but one at a time. The benefit was that each account was "personal", meaning one could not just freely access the emails of another member of the family.

Fast forward 2022, we have a brand new Android tablet. It's way more powerful, but also, the multi user accounts setup has changed. Now, all accounts seem to be available "simultaneously", in the same session.
It's fun for kids who can have access to the games of parents,
but it goes a step too far by making every email of everyone immediately available to everybody. And everyone can impersonate anyone, just by switching account, no login protection required.

It's way too open. It's even a barrier to letting the tablet be used freely by occasional visitors, so it definitely has a direct impact on usage pattern.
I suspect Android has a solution to make each account a bit more personal. But I couldn't find it. Searching on this topic over Internet delivers mountains of irrelevant information, it's hard to find anything useful for this topic. Hence the question here.


问:
How to determine why my pixel 3a running android 12 just beeped, and stop the unexplained beeping
My cell phone has a habit of beeping, with no recent notification present either on the lock screen or on the screen you get when you swipe down from the top of a home screen. (Sorry, I don't know what that screen is called.)

Casual investigation showed no way to find out why it just beeped, and three different screens showing different (inconsistent) sets of recent notifications - one of them showing only what time each app had last produced a notification, with no content.

One of these three lists distinguished between silent and non-silent notifications.

I was unable to find any interface that controlled what kind of notifications a given app could generate. The best I could do was a binary control for whether they could generate notifications at all.

I don't want to be interrupted by beeps without any associated notification I know how to find. I'd prefer to be able to get notifications, with beeps, from a selected small set of apps (calendar, text messages). Ideally, I'd prefer to apply more detailed controls (my podcast player need not tell me about automatic downloads, but I'd like to know about download failures). But given the (ahem) user friendly design, I'll settle for shutting up the random beeps, even if it means I can't get audible notifications from other apps; I do however require an audible ring for phone calls, so permanent do-not-disturb-mode is not an option.

Note that I'd be overjoyed to RTFM. Pointers to documentation will be gratefully welcomed. But from experience, Android vendors routinely customize the UI, such that a manual for e.g. a Samsung might well require me to interact with UI elements not present on a pixel running the same Android version. Also, Android 12 "made Android fun again" (according to one reviewer) by making major unexplained UI changes, as well as breaking existing functionality. So I fear that a manual for an earlier Android release will just tease me with instructions to do things no longer possible.

Android without wallpaper - is it possible?
I've just got new S22 phone and wanted to customize it. I wanted to have just a black screen as background, but I could not find any way to do it. On s22 one needs to choose some wallpaper- there is no option None.
Then I checked my old phone and a new tablet - same there ...
Then I checked all the questions here filtered by "android wallpaper" - and found nothing ...

this is crazy?!

Am I missing something or is it really not possible to have "wallpaper : None" on Android? (just simple black screen background.)

App won't start after running in custom domain

问:
Accessing An Android Device With Broken Screen Via ADB and Unauthorized Machine in 2022
I've done a lot of experimentation on this, but can't seem to get anywhere. I'm looking for guidance on recovering data from my broken Android phone(s). It seems like this is going to require some advanced forensics recovery process at this point.
Is it possible to push files or do any device manipulation if it's put in Recovery Mode/Fastboot/etc?

So far I've uncovered two methods that have saved two phones:
ONE: Use scrcpy with keys found on an old laptop backup from ~/.android/adbkeys.pub

```<code>shell$ scrcpy -b4M --print-fps --push-target=/sdcard/Download/ --verbosity=debug -t --disable-screensaver
shell$ adb pull /sdcard/errrrything* /localbox/
</code>```

This obviously only works if you can push APKs via a working debug session. I happened to have a working copy of an adbkey.pub from an old backup I found.

TWO:
Again, finding a good ~/.android/adbkey.pub and copying it to the device via push like so:

```<code>shell$ adb push ~/.android/adbkey.pub /data/misc/adb/adb_keys
shell$ adb pull /sdcard/errrrything* /localbox/
</code>```

This will push your key to the device, but obviously won't work while the phone is booted Normally unless you click "Grant Permission" on the prompt, which is impossible without a screen to see/touch.

Moving along back to my original question: Is it possible to push files or do any device manipulation if it's put in Recovery Mode/Fastboot/etc?

If so, I'd think it would be possible to remember the steps and timing for the volume/power buttons and slip in.

Any help is appreciated! If it helps, these are my phones I'm trying to recover:

Pixel 3a XL (USB Debugging On. Rooted.) - OS Version Unknown. 2 Years Old.
Motorola Nexus 6 (USB Debugging On. Rooted) - OS Version Unknown. Also 2 Years Old.

Small Note: I know this question might be seen as me trying to do something "unethical" but I can prove these devices are mine and am not trying to break in to stolen phones or whatever. That said, I understand if you assume the worst - it's probably best to think that way in life. I digress..

Thank you for reading,

Why the messages reflected in whatsapp folder are not showing in whtsapp APP?
I have a peculiar problem with my android phone. I once uninstalled and then reinstalled the whatsapp. After that all of the chats/media from the previous whatsapp sessions are deleted and are not showing in the App.
However in my phone storage I can see all older files in the whatsapp folder.

I tried to uninstall and reinstall the app again in the hope that I will restore the chats but somehow, the whatsapp never comes to the default state it just start directly, without even verifying the phone number. Even when i switch off the phone before reinstalling the whatsapp.

I also turned off the option of archiving the chats, but still nothing changed.

What should I do?

If an android device's bootloader has been unlocked before and the bootloader tampered with, can you use adb to check if it was unlocked?
If an android device's bootloader has been unlocked before and the bootloader has been modified, does using adb in a Linux terminal show you that the bootloader was unlocked before by giving the status of the bootloader as "relocked"?

If that is true then can a hacker do anything that would show the bootloader as "locked" even though he unlocked and modified it before?

Is there a foolproof way to check the integrity of the bootloader?

in app purchases stopped working, rooted device

This is on a rooted Asus ROG phone 5 running Android 12 and with the stock ROM.

Everything worked until about the middle of last month, including app purchases.

Tried all the usual obvious stuff: resetting play store app and the game in question (Asphalt 9), cleared play store's app data & cache, reinstalled game, ensured I have the very latest updates, unrooted and rebooted.

In app purchases don't work anywhere else either, so the problem isn't with Asphalt 9.

I use Magisk and the Safetynet fix, which works.

Google Wallet refuses to support tap and pay despite the Safetynet patch, in case that's related (I've always had a rooted phone and it never affected in app purchases before).

Removing Google Wallet and disabling the stub doesn't help.

Edit: Forget in app purchases, I can't even buy a paid app within play store itself after testing just now. It shows me my payment method and after authentication nothing happens; no error message.

Anything else left to try?

Can someone help me with my data transfer "in the field" issue with Android?
I have an Android phone. I have a drone, a Go Pro, and a 5TB Seagate HDD that can be powered by the phone. I have a USB-C male to USB standard female adapter, that also has slots for microSD and SD cards.

I can plug the hard drive in just fine, and my phone recognises it. But when I plug the SD card in, it ejects the HDD. It will only recognise one at a time.

The solution I have is to put the SD card from my drone / Go Pro in to the phone, and copy directly to the HDD when it's plugged in.

Now the second issue:

Many modern phones don't come with expandable storage. I need a new phone and I want to know if anyone has a solution on how I can do what I need, away from mains sockets and such. I just need to put two things in the phone at the same time.

how to turn off a samsung A10 that keeps rebooting?
I have had my Samsung A10 for about 2 years now. A few days ago it restarted by itself and got stuck in Upload Mode: It was showing a screen with two options: connecting to PC and Rebooting the device. A message was displayed at the bottom of the page saying something about missing bootloader. (I don't remember the exact message). After rebooting the phone as guided in that page (press and hold the Volume Down and Power buttons), it now keeps rebooting and does not load any further than displaying the android logo.

I googled about it and tried to do some factory reset (press and hold Volume Up and Power buttons) but it didn't help, because the phone reboots fast and doesn't allow me to choose the factory reset option or any other option in the page.

I can't even trun the phone off. It drives me crazy. Any help would be highly appreciated.

How do I check if Google One (Google Drive) backup for android is backing-up ALL text messages?
My previous SMS/MMS backup solution, SMS Backup & Restore, regularly reported that I had about a gigabyte of combined SMS and MMS on my Android phone.

I just did my first backup on Google One (Google Drive), and it reported that it had backed-up only 2 MB of SMS and 131 KB of MMS. Based on the number of photos and videos that should be included in the backup, and the fact that SMS Backup & Restore reported a substantially larger quantity of data, I'm inclined to believe that the Google backup missed most (or all) of my messages.

I double checked that, in the Google One App, the option to back up multimedia messages from my phone was turned on, then I manually started another backup. The data volume backed up was still 2 MB and 131 KB.

SMS Backup & Restore reported that I had something like 60,000 messages, and I would like to check that against the number of messages backed up by Google One. Is there any way to check the number of messages that were included in a Google One SMS/MMS backup for an Android phone?

How can one install Google Play Services on an Android-running device that does not have it by default?
I have an unusual device - an "ITX-3588J" board from the Chinese manufacturer Firefly (T-Chip Intelligent Technology Co.) using a Rockchip RK3588 ARM SoC - and it comes pre-loaded with Android 12. This Android is very, very minimal: it has virtually none of the apps that one would expect on a phone or tablet, but also has readily available root access and everything unlocked. My aim is to use it to run a virtualized Ubuntu Linux workspace (or at least whatever something like "Linux Deploy" does) to have the ability to make use of both Android and Linux apps on the same machine. While this vendor also offers an Ubuntu 20.04 native image, it pretty much is mutually exclusive with Android because each has to flash to the integrated eMMC.

Yet to install any further apps (including, ideally, a better web browser, too), I need Google Play, and that's not there. And my question is, how do you install it the "right" way, given it's the "app that installs other apps"? I have found very little entirely relevant material describing how to do this. I once managed to get it almost to go with .APK downloads from apkmirror.com, but do not remember how I did that now, and subsequent readings have made me wonder if that's not really the right way to do this. All other material I've found talks about installing on an Android emulator a la Android Studio, but is useless because they always (for that application, reasonably) just point to the appropriate AS tools, which obviously won't work here, and I basically blundered my way though that one time. There obviously has to be a way to do this because presumably it's what Android OEMs would do in the factory, but I also have no idea where that is documented.

So my question is: how do you install Google Play on a virgin Android system loaded to real hardware - including Google Play Services and the Google Services Framework - the "right" way?

Have SIMs functionalities changed since 2012?
I have a fully functional SIM card in my phone (Galaxy S22+) that works well (at least according to me).

It was suggested by the operator to change this SIM to a more modern one. There is no cost associated.

I will do it, but I am genuinely curious whether the functionalities of SIMs have changed in the last ~10 years, to the point of requiring a new one (or at least getting a new one for "better performances" (dixit the operator support)).

I was under the impression that the role of a SIM is to authenticate to the GSM cell (or facilitate communication with a foreign one, for rescue numbers) but that it was not holding any special features beyond that (these would depend on the phone, 5G for instance)

Identify child control kiosk app from icon and launcher
A child, accidentally, installed an application into this android phone, that seems to provide child control functionalities, through a locked down kiosk mode with limited screen time.

Exiting kiosk mode requires a password which the child does not know.

As a first step to recover the phone I am trying to identify the installed app. The main clue I got is the launcher it provides, and what I presume is its icon, which appears before any other status icons on boot. The icon is some sort of baby face, which makes sense given the nature of the app.

In Kiosk mode there is no possibility to drag down the notifications panel, or to enter any sort of settings, so usual ways of identifying apps do not work.

Here are images of both.

Phone is a Pixel 3A with the latest PixelExperience Plus (Android 12). Ethernet tethering device is ASIX-based USB-C w/PD passthrough power. The other end of the ethernet connection goes to the router WAN port.

How can I dump internal storage of formatted Poco X3 Pro for video and image recovery - or any other available method
I have accidentally formatted my Poco X3 Pro when it was stuck in a bootloop due to power button problem. It was thinking power button was pressed.

I did RMA it, fixed and received the phone today

So what are my options to recover image and video files that were on the internal storage?

Currently phone is locked and I will be able to unlock it in 7 days

Can you list my options currently available and after unlocking and if necessary rooting it

I can wait 7 days before using the phone

I really want to recovery as many as possible images and videos which are my baby daughter photos and videos

By the way I use windows. I have already installed ADB and drivers. ADB works but I can't see the device in the connected devices list

MAC address when discovering networks
When your Android (11) device is in the process of discovering available Wi-Fi networks (e.g. before you actually connect to one of them), is your Android device exposing its MAC address to these hotspots/routers or is this search for networks done without utilization of MAC address? And if MAC is used, is it also randomized like it is by default when connecting to the network or is in this case using real MAC?</p>

问:
How do I get Family Link to ask for approval for the URLs apps are trying to access?
My son has an A12, and we have Google Family Link set up on it, with the Chrome content settings set that he can only access approved websites. When he tries to go to a new website in Chrome he's presented with a screen where he can request that we approve the website; a notification then pops up on my phone (Galaxy S9+) where I can approve or deny. This works pretty well. But when an app needs to access online content hosted on a new site, my son is not presented with that screen nor does anything pop up on my phone. This makes it so the app just appears to not be working. Sometimes we'll get a message like "cannot resolve hostname" while other times the app just doesn't function (or gives a vague "something went wrong" message).

The first time this happened, I was able to go into the Chrome content settings on my phone's Family Link app, view the list of approved websites, and add the app's website. (I inferred the hostname from a texted download link - we had to invite our son to use the app so it sent him a text message with a URL.) This got that app working. Now we are dealing with a second app where it is not working (no error messages, just not displaying things it should). I believe it is the content blocking again, so I added what I thought the hostname would be, but the app still doesn't function. (This time I tried to infer the hostname from the help website and the domain for the support email address.)

I would love it if Family Link would prompt for approval/denial for the site(s) that apps are trying to access so I don't have to do this scavenger hunt. Is there a way to configure it to do that? Or is there any way to see what URLs Family Link / Chrome is blocking? Or some generic log/event location that I can look to see if the app is logging an error message I can work to resolve?

WhatsApp restore problem: "Unable to restore your chats from this backup. Do you want to restore your chats from an older backup?"
I tried all day to move my WhatsApp from a phone to another. I had everything backed up, but when I verified on new phone, I realised that I forgot the password and the encryption key to restore from Google Drive, but it was too late to change them because I was already logged off the old phone.

So I verified again on my old phone, but the chats were already lost. So I wanted to restore chats on old phone with local backup, reset password, and then back up on Google Drive and do everything on new phone, but I get this error when I try to do the restoring.

Unable to restore your chats from this backup. Do you want to restore your chats from an older backup?

Skip Restore from older

Now, if I try to press on restore from older, I get prompted the following:

If you previously backed up to Google Drive and want to restore it, give WhatsApp permission to check your Google accounts for backups.

Skip Give permission

And when I press on give permission, I get asked to chose a Google account, and when I press on mine, it goes back to the same thing asking to give permission and it won't to something unless I press skip.

Please help.

问:
How can I extend the length of the batterystats history?
I am doing some power consumption analysis using Batterystats and Battery Historian. The problem that I am facing is that the length of history I can get from the phones varies widely form brand to brand.

On Samsung phones, for example, I have gotten history of up to 5 days, whereas with Pixel phones I can't get more than 1hr of history. Is there a way to increase the time period logged by the system?

Currently, when I do a power consumption test, I follow these steps:

Reset logs with adb shell dumpsys batterystats --reset

Run adb shell dumpsys batterystats --enable no-auto-reset to prevent resetting of the logs

After the test, retrieve the logs with adb bugreport bugreport.zip

Analyze the logs in Battery Historian.

But I can't find any ways to get a consistent history from phone to phone. As stated above, the history length will be different depending on the brand, even if the test period is the same.

I would like to get at least 12 hours worth of data to perform overnight tests. Even better if I can get multi-day data for long term testing.

Edit: Edited the steps I take to test to add more detail and clarity.


问:
Open an SSH terminal through a bridge SSH host
To connect to a particular server REMOTE_HOST I have always used ConnectBot and found it perfect for my purpose. But now I cannot connect to REMOTE_HOST directly anymore and need to connect to some BRIDGE_HOST instead and create a tunnel from a localhost port to REMOTE_HOST:22. A particularly annoying detail is that I must connect to BRIDGE_HOST with a password and I cannot use keys; it is bad, but I have no control on this.

It is quite easy to setup this in OpenSSH on Linux, for one simply needs to add this in .ssh/config

```<code>Host REMOTE_HOST
  ProxyCommand sshpass -p BRIDGE_PASSWORD ssh -W %h:%p BRIDGE_HOST -l BRIDGE_USER
</code>```

and then any connection to REMOTE_HOST works as usual and the tunnel is transparently brought up when needed. The user can be completely unaware of the routing through the tunnel.

I would like to achieve the same in Android. What I have works, but it is a little clumsy. I ended up using JuiceSSH to setup with a single tap on one of its widgets a tunnel ending in localhost:2222; I need JuiceSSH because I do not think one can save a password with ConnectBot. I then connect to REMOTE_HOST through a tap on a ConnectBot widget, with the same host config I used in the past and simply replacing REMOTE_HOST:22 with localhost:2222; I use ConnectBot because it seems to allow a better control on post-login automation (or, at least, I had it perfectly configured for me and I like the terminal interface).

Again, it works fine. I am connected in two taps: JuiceSSH and then ConnectBot. Still, it is clumsy, for after a while, if unused, the tunnel seems to become stale, so I need to kill the tunnel (a single tap more), bring it up again, etc. Nothing catastrophic, but could it be done more easily/elegantly? OpenSSH is perfect, in this respect.

In order to attain the maximum charging speed of 21W on your Pixel 6 (23W on Pixel 6 Pro), the charger must support Power Delivery (PD, Programmable Power Supply (PPS), and be rated to 24W or higher. You also need an e-marked cable that can negotiate the exact current between the charger and the phone.

Why is a Chinese symbol on some of my WhatsApp contacts?
I have WhatsApp application installed on the latest version of Android on my phone.

I've noticed that for some contacts, a Chinese symbol (which I translated using Google Photos with automatic language detection and seems to mean "Telephone" in simplified Chinese) appears close to some of my contacts:

Why is that symbol appearing? I've tried to find a common pattern across these contacts but I couldn't find any: the symbol appears on contacts that I'm sure they don't have my number (but other contacts that I'm sure they don't have my number isn't showing it), and vice versa - some contacts that I am sure they have my number and still the symbol appears.

Would you have any idea of why that happens? I couldn't find any explanation on the internet and I wouldn't know where to ask if not on this forum.

USB-C Audio interface doesn't work when placing calls but works for everything else
I have a Presonus Studio 24C and a Samsung Galaxy Xcover Pro. I have installed all the latest updates using the Galaxy Store, the Play Store and also I have completed all system updates.

For some unknown reason on all apps tested I can easily use it to record and listen to voice memos and any other tasks tested such as listening to music but as soon as I place a call it reverts back to the internal phone microphone and speaker and I don't understand why.

I've tried to research this issue very extensively and I was not able to find any answers to this problem.

What actions need to be taken so that I may use the audio interface when placing calls? Why are calls different than recording and listening to voice memos? Is this issue Samsung specific? If this issue is a result of a Samsung customization what actions would need to be taken to revert the customization?

wDisplay Android hotspot in macOS Wi-Fi menu
Preface: I suspect the answer is "no", but I reckon I'd shoot my shot.

MacOS has an auto-discovery called Instant Hotspot feature for shows nearby iPhones that are available to provide a hotspot. These are listed in the WiFi menu along with their battery level and cell signal strength.

Crucially, this appears before a hotspot has actually been started. Clicking on the menu entry will remotely enable the hotspot on that iPhone.

Has anybody managed to make an Android app that let's an Android play ball with this feature?

If this feature relies on iCloud accounts (I don't think it does, I can see strangers' hotspots) or some central registration server, then this will obviously not work. On the other hand, if it's just using some local WiFi frames, then it seems plausible to reverse engineer and spoof. Is there any existing work on this?

How can I install Magisk alongside LineageOS on my S10?
I have an S10, which was not bound to any carriers. I managed to install LineageOS and GApps following the steps from LineageOS' official site for my model and everything seems to work perfectly. Before installing LineageOS, my phone had the stock Samsung Android 12 installed and, looking at the install instructions over at Magisk's official website, it seems like I have to perform a particular type of installation to be able to install Magisk.

What I am wondering about is:

Do I have to use Odin? I am a Linux user and over at the website it states that Odin only runs on Windows.

Watching videos online, none of the video tutorials seemed to use a Samsung + LineageOS when installing Magisk; they installed Magisk + stock Samsung Android, which brings the question if I need to download and install the official firmware from the Samsung servers or can I just get away with flashing Magisk directly on the device?

Tap yes on your phone or tablet, which I couldn't

Lenovo P11 Plus - Only admin can log-in into table at first after restart
I got a P11 Plus (Android 11) for my son, and I am having troubles with a behaviour that is extremely frustrating.

When setting up the tablet, I first set myself as the owner/admin (i.e., the first account to be set-up in the table was mine).

Then I proceeded to set my kid's account (child under 13). I got kids space working, family link, etc.

What I noticed is that if the tablet is restarted, only my account can unlock the tablet.

My kid's account (or any other account besides my own, the admin) is greyed out and cannot be selected at this point.

If I unlock the tablet, then other users will be able to log-in with their accounts.
This renders the tablet usless to my family unless I am around after a tablet reboot!

Now, had I made my son the first user in the tablet, he would have been the admin. The result is a ridiculous situation in which he would be able to log-in a temporary guest account and bypass all restrictions, EVEN IF I BLOCKED HIM FROM CREATING ACCOUNTS. Indeed he wouldn't be able to create accounts, but he would be able to mess around with the guest access all the same.

Anyway, I'd say it is perfectly reasonable to expect that a parent would be the first account (admin) of a tablet, before it is handed over to a child.

So how can I allow my kid to log-in into the tablet after a reboot?

Thanks.


问:
Force discard Chrome tabs?
It seems there is a performance issue that Chrome on Android consistently exhibits with tabs that share two characteristics:

They share the same origin.

They make heavy use of Javascript to load content dynamically.

An example is having multiple tabs displaying different pages under reddit.com.

When Chrome visits a lot of these tabs, it appears that Chrome will not discard data loaded from most of the tabs as long as one tab from the same origin remains open. After going through a dozen tabs or so, this results in very high memory use, as well as old tabs still being loaded when they are switched back to.

Interestingly, an OEM tool on my device still shows Chrome in this case as using only a relatively low amount of memory, around 300MB. However, the same tool also shows available memory as extremely low, with no user applications other than Chrome using significant amounts, and ending the Chrome process or closing all the offending tabs in Chrome immediately produces a major improvement in UI responsiveness along with a very large increase in available memory. Perhaps it is some system-level web rendering process that is holding data from common origins in memory. But Chrome is clearly still choosing to retain those pages.

The expected behaviour, which is what happens when you have lots of JS-heavy tabs from different origins, or lots of tabs from the same origin that don't make heavy use of JS, is for Chrome to silently discard unused tabs from memory while still keeping them open and reloading them if they are displayed again.

This is quite frustrating as I believe I can see quite clearly what is happening, and the fix should be so easy, but there simply aren't any UI controls exposed for it, so it can still lock my phone up for tens of minutes at a time. Additionally, I've made a habit of doing most of my web browsing in Incognito Mode, so when Chrome freezes and then has to be closed, I can lose pages that I still wanted to read.

Is there a way that Chrome can be forced to discard open tabs? Not close, only discard, as I may still want to go back to them.

Installed OpenVPN server on rooted Android, but routing is not working
I wanted to install OpenVPN server on rooted Android and found a solution on StackExchange. I rooted my phone, installed Linux Deploy, installed Ubuntu in it and compiled latest OpenVPN server and EasyRSA.

When I start OpenVPN server on my phone and I can connect to it with a client, but I can't ping anything but myself. Below is my server configuration (same configuration works fine if I set it up on real Ubuntu server):

```<code># server 10.10.1.0 255.255.255.0
# push "redirect-gateway def1 bypass-dhcp"
# topology subnet
# push "topology subnet"
# push "dhcp-option DNS 84.200.69.80"
# push "dhcp-option DNS 84.200.70.40"
# duplicate-cn
# data-ciphers-fallback 'AES-256-CBC'
# keepalive 10 120
# persist-key
# persist-tun
# explicit-exit-notify 1
# log-append /var/log/openvpn.log
# verb 3
</code>```

I haven't installed iptables or ufw so that's not a problem.
My router LAN ip address is 192.168.2.1 and my telephone ip address is 192.168.2.28 (wlan0).
My OpenVPN server is on 10.10.1.1 (tun0) address and my OpenVPN client gets 10.10.1.2.

On the StackExchange link I posted, guy said that Android ignores main table at all, so we should create custom rules and insert routes.

Without adding any routes to server, I can't even ping 10.10.1.1 from my client, but when I add sudo ip route add 10.10.1.0/24 dev tun0 table 5000 ping started working for 10.10.1.1 and 192.168.2.28 and that's it, I can't get to 192.168.2.1 or any further.

I tried adding sudo ip route add 192.168.2.0/24 dev wlan0 table 5000 but nothing changes.

I even tried sudo ip route add default dev wlan0 table 5000, but when I add that, I can't even connect from my client to my server any more.

Anyone have any idea how can I fix this?

Sys can't boot, recovery broken, adb disabled, zero ideas [Oneplus 5T]
I tried to update from crdroid 7 (Android 11) to 8 (android 12) with a clean flash (no format data though) and now my situation is the following:

System is stuck on boot animation

in fastboot, my device is not recognized, adb devices  shows nothing, and fastboot flash waits for devices. I tried reinstalling adb and drives, but my guess is that system is sorta installed and disabled usb debugging, which is off by default. I also tried from another pc, device is not found by it.

twrp is broken, it remains stuck on the twrp logo. Every 5 minutes or the screen flashes black.

I uninstalled magisk before flashing anything.

The devices is not encrypted, I removed the password before starting the process

Now, the only hope: the devices is recognized in recovery mode by the pc, even though windows does not mount the storage. Here is what I tried:

adb root says adbd is already running as root, but I'm unable to access the root in the adb shell.

I tried adb pull \data\media\ but it fails to copy: open failed: Required key not available.

adb sideload the recovery or a rom or magisk ends in error: closed

adb pull /system/build.prop ends in remote object '/system/build.prop' does not exist

So I have not idea how to get the required key to pull the data or enable the usb debugging through adb (so I could reflash the recovery). I have zero clues on how to recover the data and/or the phone so here I am. (I also have to head out from home so I won't be able to reply today)

Samsung: switching to new phone
I recently switched phones for the first time in several years. My vague recollection from past switches was that it was fairly smooth. Here is what happened this time.

I switched from a Galaxy S9, Android 10, to a Galaxy S9+, also Android 10.

After starting the already factory-reset S9+ I entered my Google account details and followed the prompts.
Said prompts led me to use Smart Switch, which I have used several times in the past. Texts, call logs, screen background, icon placement all transferred successfully in a few minutes. The phone then finished installing all the apps and that was it.

But soon I noticed that no app settings have been transferred; this ended up cascading in a couple hours of looking for passwords, re-loading my credit cards in my pay apps, having to manually backup some apps, and even having to call the IT department at work to reset the MFA settings and register the new phone. And several minor problems with other apps.

All in all, not terrible but it was quite a task to be fully functional again with the new phone. My original plan was to switch phones again fairly soon, and now I'm dreading that moment. My question is, did I do something wrong? Is there a way to have a  smoother transition between Samsung phones?

How can I install a system app without restarting the device?
I have a requirement to install two APKs in the /system/priv-app directory. But I can't restart the device (this is due to business requirements).

So, is there any way I can install the two APKs in the /system/priv-app directory without restarting the device?


问:
Slow internet connection on Android phone, while no issues on other home devices
I'm having an issue with the WiFi connection on my Android phone (OnePlus 6, Android 11). For the past few days, some apps started to work slowly, I see spinners all the time, indicating that the contents of the apps cannot be loaded.

As soon as I switch to mobile data (LTE) everything is OK. Also, other home devices (2 laptops and an iPhone have no internet issues).

What I tried:

Changing the position of my router. No luck.

I used a WiFi Analyzer app to find more optimal channels to use and I manually set them on the router. At first, setting a channel helps (the slow apps start working well again), but after a while, the problem comes back and the apps become slow again.

The router provides both 2 and 5GHz frequencies, applied automatically whenever possible. My internet speed is ~500Mbps.

Is it my phone or is it my network? No clue. How can I troubleshoot this further?

问:
Find text within web page from Samsung Internet browser
Similar to this question, but for the Samsung Internet Browser (which is opened from the Google app).

As is the case with PC desktop Chrome, using the never-fail CTRL-F and F3 combination does yield the hit count in the search box along with the highlighted hits in the right-hand scrollbar. On the tablet, however, most of the resulting page gets covered by a new layer of white nothing over it, which cannot be removed, unless it is then closed, upon which the search items are lost.

As to the alternative, some suggestions directed us to click on the Google "Home" area to acquire the search bar. Somehow, the device does not present as a candidate for Google Home, there may yet be another way to find text on a web page in the Samsung Internet browser.


问:
Upgrade to Android 7.0 but keep old built-in apps, user apps, etc
How can I upgrade my Samsung Galaxy S5 from Marshmallow to Nougat without changing the built-in samsung apps, losing user apps, settings, and keeping the Samsung Marshmallow UI? I mean, only updating the kernel and SDK to install newer apps.</p>


问:
How can I test Android 13 without commiting to it forever?
Google says this about the new Android 13 builds:

Warning: The Android 13 update for Pixel 6, Pixel 6 Pro, and the Pixel 6a contains a bootloader update that increments the anti-roll back version. After flashing an Android 13 build on these devices you will not be able to flash older Android 12 builds.

Is there any way around this? A few ideas I've had, but not sure about any of:

Will just having an unlocked bootloader bypass this?

Will it work to extract the zip file and then manually flash everything but the bootloader?

Will reflashing vbmeta with --disable-verification protect me from this?

Android Emulator Failure
I am using Android Studio on a Ubuntu virtual machine.

Android Studio allows us to pick a virtual device from a list of devices and system images. After find out my computer could not handle a high resolution option, I picked the appropriate ARM image. But when I launched the device, I could see that it seemed the emulator was trying to load but it stopped after just a few seconds. with this error. Is there any way to trouble shoot this? Is there a log somewhere?

问:
How to view which apps are using the most RAM?
I recently bought a Samsung Galaxy M52 5G. Now for the past few days, it has been slow/erratic even though I don't have that many apps. The most troubling is that Android reports my RAM usage is high even though there are no background apps, or at least that should be the case when I just rebooted the phone.

Is there any way to tell which apps are taking most of the memory?

问:
Symlink temporary file
I'm attempting to backup my Signal chats totalling almost 15GB, which presents a challenge in my 32GB phone. I simply have no space to do it, and even stripping the system of pretty much all apps except Signal is not quite enough, and naturally would be quite a lot of work.
So, I was trying to create some sort of symlink between my external SD card and the Signal backup directory. I managed to do it via a su -M session (via adb shell but Termux also works) by using mount -o bind /storage/<sdcardID>/Signal /storage/emulated/0/Signal (having previously created that Signal dir on main storage). Files I create are perfectly mirrored and actually live on the external storage, however, the temporary file Signal creates for the backup is nowhere to be found. It doesn't even appear when I ls either path, yet it does appear when I navigate to it using any file explorer app.

How come? Is there a way to correctly link that?

Thanks in advance!

PS: Backups have been improved for Android 10, but I am on 9, so that's a no go.
