问:
Is it Android's native feature to be able to select text in the task overview (switching)?
On a Pixel phone, in the task overview (I do not know the official term for this screen, but the screen that shows cards of running apps' screens), if I long-press some text, it allows me to select the text, even if the text is not selectable in the app itself.

Is this Android native feature? Or does it come from a Google app? Do other phones have this feature?

Phone to phone bluetooth fail
I am trying to work out the following strange Android bluetooth problem and would appreciate any suggestions.

I have 3 android phones - Redmi Note 7 (LineageOS 18.1), Redmi Note 2 (Resurrection Remix RR-N-v5.8.5, Galaxy S7 (Lineage OS 19.1) and an Teclast M40SE (stock ROM).

With each device, I can set up a bluetooth connection to a headset, car audio, laptop etc without any issues.

However, when I try to connect any of the Android devices, I get the pairing request which I allow straight way and the icons appear under connected devices for a few seconds and they get disconnected. It does not matter which pair of devices I use, the result is the same.

I did reset network configurations on devices and started afresh without success.

Any suggestions? Thanks.

How to stop Android 12 or 13 asking for password every time after lock screen
I just upgraded from Android 11 to Android 12 and now It asks me every single time I unlock the screen. Before, it would ask me for the password only once every half an hour as I had configured it.

How can I get back to that behaviour in Android 12 that only ask me for the password once on a while?

Is there any way to have audio output through one Bluetooth device and input through another
I have an Android phone and Sony WF-1000XM4 noise cancelling earbuds.

These work great when listening to music or making calls over Discord. However, I'm often in high noise environments where the mic pickup does not work and I have to use a different boom mic.

However, if I am using the earbuds to provide audio output, I can't use the bluetooth mic for input. And vice versa, I can tell my phone to use the mic but then no sound comes out of the earbuds.

I can connect both devices to my phone simultaneously, is there any way to tell Android to use one Bluetooth device for output and another for input at the same time?


问:
How do hackers change (mask) IMEI numbers?
Recently, I saw a "Google Pixel 3XL" with a seller, and he claimed that its IMEI number had been changed. When I asked, how did he know that? He said this is because of the "Magisk" app installed. Then he verified it through our official country's website and it was an IMEI of another smartphone, "Sharp Aquos r2." He also mentioned that upon factory resetting, the IMEI number will be lost.

So how can the Magisk app change the IMEI number? I think it just masks the IMEI.

Moving Screen Position Entirely
My phone screen broke (I dropped the phone) - I wanted to repair it, but it costs a lot.

The company where I bought fixed the screen for me, but it doesn't work properly still - at least not 100%.

Marked part of the screen on the image is not responding to touch.

The solution I came up with is to somehow in Android Developer settings move the screen these 50px down, so it starts under the camera, and so I can use the phone like nothing ever happened.

Do you guys know how it can be done?

Android 12 popup over the keyboard (screenshot)
I'm having an issue with Android 12, on a Samsung Galaxy 22 Ultra.  It is showing some kind of popup over my keyboard and it sits there way too long so I can't continue with what I was doing and I have to wait for it to decide I've looked at it long enough.

App Notification is OFF or everything not DM related

问:
Can IMEI number be changed?
I wonder if IMEI number of phone can really be changed. I've been searching in the Internet for a while, but did not find a satisfying answer, because all of them differ from each other. I am going to summarize what I've found by now:

IMEI cannot be changed because it is stored in ROM memory,

IMEI can be changed using certain apps that are able to do this,

Such apps only change IMEI number that is displayed on the screen, but the real one stay
untouched (supposed that it is true - how can I check if displayed IMEI is real or fake
and how to check then the real one ?)

You can change IMEI via Service/Engineer Mode that can be accessed by typing secret code

(I tried this and I couldn't change there anything - there were only infos)

So as you can see, these answers are completely different. Could anyone refer to it?

问:
Can someone please confirm expected output from logcat on volume button hardkey press and release?
I have a stock OnePlus 8T+ 5G TMO that has been displaying very strange behavior.  It would ask if I want to boot into safe-mode every time I try to power down or restart, and sometimes it would continuously flash on then go dark again after going to lock screen, as if the power key were being continuously spammed.

Eventually, I realized it was behaving as if the volume up key were "stuck".  This is strange, because the hard key itself is very clearly giving mechanical feedback on both actuation and then release.  Nonetheless, I thoroughly cleaned the whole phone with a liberal amount of 99% isopropyl (after powering down from the recovery menu), and then was successfully able to power back on and have normal operation again.  However, I did notice the volume keys were still behaving a bit strangely; to begin with, I only confirmed it was stuck in a "down" state at all because after booting into the recovery menu, it immediately began to rapidly cycle through the menu choices as if the button were held down.  Pressing down on any key (including itself) would pause the cycling, but letting go would immediately resume it.  After the cleaning, it would have practically no delay on input nor repeat delay, almost like it had "Turbo Mode" turned on like on the old-school modded controllers.

Since it's at least in a usable state now, I enable ADB and hop on my Chromebook to take a look at logcat.  So what I'm seeing is that each individual key press is getting logged as four lines:

# adb -d shell logcat
--------- beginning of main

08-18 21:46:14.770  1176  2717 D APM_AudioPolicyManager: setVolumeCurveIndex device 00000002, index 1

08-18 21:46:14.774  1176  1780 D APM_AudioPolicyManager: setVolumeCurveIndex device 00000002, index 1

08-18 21:46:14.775  1176  1780 D APM_AudioPolicyManager: setVolumeCurveIndex device 00000002, index 1

08-18 21:46:14.775  1176  1780 D APM_AudioPolicyManager: setVolumeCurveIndex device 00000002, index 1

Unfortunately, I'm not too familiar with troubleshooting hardkeys, so I'm actually not too sure whether this behavior is expected or not?


问:
What are all those different localhost domains that apps connect to?
I'm using the Blokada adblocker on my phone, which acts as a vpn and can show me all the domains that apps request to connect to and let me switch them between an accept list and a deny list. Whenever I install an app with known trackers, I try to block as many of those domains as possible while keeping the base functionality of the app.

I noticed that my log has about a hundred of domains with localhost in the name, many of them not even looking like a url. For example, among some that my phone tried to contact hundreds on times:

```<code>localhost_name
localhost0#3}
localhostfo
localhostz\012({
localhostsys
localhost_code
localhostdn.com
localhostgs
localhostsysu
localhostms
localhostal.org
localhostp.net
localhostde
localhostt.com
localhost.com
localhostx.com
localhostahn.de
localhoste.com
localhost=tun0
</code>```

Some look like actual domain urls accessible on the internet, some not. Some have those weird special characters in them. What are they? Actual domains? Or are they pointing to a webserver running on my phone like normal localhost would? Why are there so many of them?

My instinct was to block them on sight because I don't want apps to keep track of my phone connecting to their servers from different IPs, effectively mapping out everywhere I'm going. And I have a hard time trusting a domain name looking like "localhostz\012({". Is there a reason I shouldn't block them?


问:
How to give `adb run-as` external storage permission?
So far I've been using adb run-as and cat to extract files from apps private storage /data/user/0/com.myapp.android. Simply catting the file and piping it to a local file on my pc worked a treat.

Now i'm trying to do the opposite, send a file from my PC to apps private storage.
I thought of using adb push to send the file to a shared storage location and then using run-as to copy the file internally to the private storage.

I have given my app READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permission, and linux permission knowledge seems to suggest I should be able to access the shared storage, but I won't, as seen in the example:

```<code># Running as default user works fine
OnePlus9Pro:/ $ ls -l /sdcard/Android/data/com.myapp.android
total 3
drwxrws--- 2 u0_a347 ext_data_rw 3452 2022-08-19 12:03 files

# Running as the application won't work
OnePlus9Pro:/ $ run-as com.myapp.android ls -l /sdcard/Android/data/com.myapp.android
ls: /sdcard/Android/data/com.myapp.android: Permission denied

# But the application user is the owner of the directory?!
OnePlus9Pro:/ $ run-as com.myapp.android id
uid=10347(u0_a347) gid=10347(u0_a347) groups=10347(u0_a347),1004(input),1007(log),1011(adb),1015(sdcard_rw),1028(sdcard_r),1078(ext_data_rw),1079(ext_obb_rw),3001(net_bt_admin),3002(net_bt),3003(inet),3006(net_bw_stats),3009(readproc),3011(uhid),3012,50347(all_a347) context=u:r:runas_app:s0:c91,c257,c512,c768
</code>```

From here you can see the shared storage (/sdcard/Android/data/com.myapp.android ) is owned by user u0_a347 with full permissions.
run-as com.myapp.android is executing under u0_a347 and in addition it has ext_data_rw group as well.

How can I access both shared storage and application private storage at the same time?

How to ensure a device will allow me to OEM unlock it, so that I can install a custom ROM to it when I have the IMEI?

TPM (Trusted Platform Module) vs. TEE (Trusted Execution Environment) - can credentials be *stored* on both?
TPM is physically isolated from the rest of the system (i.e. it is a standalone chip on the mainboard), while TEE is a secure area of the main CPU.

The key function of both TPM and TEE is to do cryptographic calculations, but can they also store credentials/keys used in these calculations?

I know SE (Secure Element - also a standalone chip) is used exactly for storage purposes, but only 30% of modern smartphones have SE integrated (and mostly expensive models). So how is the credential storage task solved in TPM/TEE scenarios?

How to mount network drive so it's accessible by other apps file picker?

Mounting the network drive with Cx File Explorer or SolidExplorer does not seem to make the drive accessible to other apps.

Is there a way to mount the NAS as a subdirectory of the internal storage? Or create a symbolic link to the mounted network drive?

How to revive an old 4.2.2 phone?
Because of "reasons" (or at this point mostly out of curiosity) I find myself with an old Wiko Iggy phone running Android 4.2.2 that after being factory reset is unable to install anything at all from the play store. Searching for specific apps in the store returns only books or movies, searching for apps in a browser and opening the relative page on the store shows the app all right, but tapping "install" only goes so far as showing the permissions overview; agreeing and trying to install produces a "no connection" error (of course the phone is connected to a WiFi network and logged in into a google account).

问:
My android phone won't accept correct PIN/password after I tried to change my screen lock password
I have a Realme 8 phone as my primary device.
It had a PIN and my fingerprint set up as the screen lock. Around a week ago at around 4 am, I decided to change my PIN as I keep changing screen locks after some 5-6 months. So this time I decided to use PASSWORD (which contains alphanumeric strings and not just numbers like PIN) which I use on my laptop as well.

So I navigated to settings to change it, I entered my current 5-digit-PIN as asked, then I enter my new password (alphanumeric) and then at the final step when I had to tap on "Done", I think I accidentally pressed back button.

Now after that, when I turned my screen off, I was expecting new Password screen but it was not there (yes I get it, I didn't tap on DONE so it makes sense). As expected, it was again PIN screen which makes sense.
What does NOT make sense is that when I entered my old 5-digit-PIN, it said incorrect password try again. I've tried my PIN like a 1000 times, it just don't work.

But I could still use a fingerprint right? Yes I was able to unlock my phone through fingerprint.
As I researched more about this issue, I found an easy fix to this common problem, which was to restart the device (worst mistake). It worked for everybody except me.
I restarted my device.

Bang. Now I cannot even use my fingerprint (as when an Android device restarts, it doesn't let us unlock the device with fingerprint, a well known fact). So I'm locked out.
Is there a way to unlock the device with the fingerprint after rebooting?

I cannot factory reset it as it has Gigabytes of my data that I have unfortunately not backed up anywhere else.
Please note that the screen calibration is not damaged, I can see what numbers I am typing in the PIN field. It just does not work.
Also there is no option of Forget password as well as Google forget password.
I can try PINs as many times I want. There is no timer after, say 5, incorrect attempts. I have tried 100 PINS at a time consecutively.

I can boot into Realme's stock recovery, it has an option of "Update phone (without losing data)" when I click it, it asks for a "Password" this time (not specifically PIN), on an alphanumeric QWERTY keyboard. But neither the PIN works, nor the password that I had entered at around 4 am.

USB debugging is turned off, hence I cannot try ADB. I can access the notification action center and can connect with WiFi as well.

Any idea what should be done now? It has my really really important data I cannot afford to lose.
It also didn't had an SD card hence I'm worried if formatting it and then data recovery will work or not.

Any help is appreciated. If someone wants to know the PIN or password for some reason, let me know. Thank you everyone

Moreover, in some cases, I need to access pictures and files.

In which path should I put files so that they can be accessed by Android applications?

WiFi sometimes cuts off when connected to WiFi repeater
My redmi note 11s internet cuts of sometimes when I'm connected to WiFi repeater. When u turn my WiFi off and on it works again. This doesn't happen when I'm connected to the main router.

问:
get emails from specific emails - instantly
I'm trying to make sure that when I get specific emails, I get notified instantly, loudly, and even if I'm in "do not disturb".

The emails are going into a gmail account. These are things I've done so far:

Set up a new email, log into that email on the Samsung "Email" app, turn notifications on for that email app, create a filter on the original email that forwards to this email.

Create a filter on the original email with a label, go into the "gmail" app filter notification settings, allow syncing on the filter with notifications.

both these methods work to get notifications on my filter... but both of them seem to be delayed about 15 minutes (I assume the filter and send and perhaps the "email" app make up that 15 minutes on the first option... and the filter and syncing within the phone make up the 15  minutes on the second option).

How to get the userdata of an app which has allowBackup=false (Firefox)?
A while ago my Firefox "crashed" and started a new session, without the possibility of reopening them.

I'm on an unrooted Android 9 phone, so I tried using the adb backup command, but to no avail.
I later found out, that firefox has this feature disabled in the manifest. (Why?)

Is there any workaround or tool to get to the /data of Firefox?
Or am I out of luck and have to start new?

Devices without hardware MAC addresses
I vaguely remember a comment on the Stack Exchange network saying that some Android devices have no permanent hardware MAC address added at the factory or later on. The comment mentioned that U-Boot makes a permanent unchangeable hardware address unnecessary.

Are there Android devices that ship with no permanent hardware MAC address in EEPROM, flash storage, or elsewhere?

Please mind that this question is not about MAC address randomization.

Create a one-way contact sync between phones
What I am trying to do is distribute phones to various employees. Whenever a new phone is distributed this number should be added in all of the existing phones. The employees that are using these phones will also inevitable add other people in their phones but these contacts are not to be synced to the other phones.

I was thinking of using like a "master phone" that has only the contacts from the phones that we distribute and only when on this phone a contact gets added it is synced with the other phones, but I am not sure how to realize this.

Another option would be to tell the employees to never save contacts on the Gmail but always on the internal memory of the phone, but doing things that way does allow for human error.

I am curious about what your insights are. Is there a reliable way to do this?

How to exclude subfolder of DCIM folder (DCIM/SUBFOLDER) from auto syncing in Google Photos app?
Google Photos fully auto syncs DCIM folder of Android (including all its subfolders) and I can't find a way to select only specific subfolders inside DCIM folder to be synced

I have Screenshots subfolder, subfolders from other apps and so on and I don't want them to be synced.

I want to auto sync only DCIM/Camera and that's all.

I can only disable auto sync for the whole DCIM folder, and absurd fact that in the Google Photos app "DCIM" folder is shown as "CAMERA" folder, so basically it ignores any structure inside DCIM folder and just uses the same logic for all files inside DCIM and inside its subfolders as for one category


问:
Local HTML file links cannot be followed
Background:

I use my tablet for Geocaching, specifically to have cache listings available in the field. For this purpose, I have a program called Geocaching Swiss Army Knife (also known as GSAK) generate HTML files on a regular basis, which I have copied onto a memory card. Normally, when I go out into the field and look up a cache, I have the index file as the home page in a browser, and then follow the links from the index to the actual cache listing.
I have been using a Dell Venue 8 for this task, but the battery finally died (won't take a charge),
and Dell has gotten out of the Android tablet market, so I bought a Samsung S7 Fe to replace it.

Problem:

Unfortunately, I can load the index file fine, and all the files are there, but none of the multiple browsers I've tried will allow me to navigate beyond the index file. The error I get is:

"Content links are blocked", it may have been moved, edited, or deleted

(This varies by browser, but the gist is the same)

Is there a setting that will enable the browser to follow links between local files?

Keep the internet connection alive when device idle
I have Family Link installed on my son's phone. However, if he is not using his phone, the phone goes into some idle mode, and then you cannot connect remotely via Family Link to see his location.

Is there any way to wake up the device by itself e.g. every 10-15 min and keep the internet connection alive, e.g. wake up the device, not necessarily the screen, it can run in the background and ping some sort of internet connection, so that then we could access his location via the Family Link?

I understand that the battery will be impacted, but a ping every 10-15 minutes should not be a drama for the battery.

I'm not asking about a way to fix Family Link's location either, I believe that if the device is idle, there isn't much that one can do to connect remotely.

We both have the latest Android.

Using Android TV v10 with external keyboard - Logitech Touch K400 Plus
I'm really puzzled over the fact that my logitech keyboard mentioned above can switch between English and my native language using simple alt key stroke when using this keyboard directly with Samsung's Tizen OS system.

However, when using my streamer with Android TV OS - a more modern OS, things get worse and I see no option to switch between languages.

I tried using many key combinations among them shift+space ctrl+space win_key + space alt
and simply nothing works.

On the language definitions setup of my streamer I get my native language set and in Gboard keyboard settings: English and my native language.

None of these setup helps to switch between languages, I'm stuck with the interface language of my system(native) and can write in Englush just when holding shift + some letter or using CAPS LOCK, only then I get English but in Capital letters!

Please let me know if this is problem of my streamer\android TV or keyboard itself?

问:
Calling wakeup() in power manager from kernel
I have a TV running android which has a broken WoL functionality. It wakes up the device but doesn't turn on the screen. I managed to fix this by writing a kernel module which runs a usermode script which waits for a "remote control service" on the TV to be reachable and then uses that to turn on the screen. The remote control service calls the wakeup() method in the powermanager. So instead of waiting for the remote control service I now want to somehow call wakeup() directly, or whatever happens when that is called. I managed to follow the code until IPowerManager.aidl. However, I can't figure out what exactly implements that method, meaning what exactly happens when it's properly called.

What's the best/fastest way to make the device wakeup from the kernel (or from a userspace script running as root)? I tried the input event stuff but the input binary just exits with an "aborted". It works when I manually call it using adb, so I assume it doesn't work because it is missing some kind of environment or something.

问:
Can I add phonetic names without affecting sort order?
The stock Android contacts app on my Samsung S10+ has the ability to add 'Phonetic First Name' and 'Phonetic Last Name' to the contact record, in theory to help with Google Assistant voice matches (this is to support the verbal expression 'call john' matching both 'Jon' and 'John', or 'call Cathy' matching both 'Kathy' and 'Cathy'). (You need to use 'edit' and then 'view more' to see these fields).

But when I add the phonetic names to the contact record, the app sorts those entries by the phonetic last name, even though I have first-name sort enabled.  Thus - 'Jon Zee' sorts under 'J' without a phonetic entry, but sorts under 'Z' when I add the phonetic entry (John Zee). As a variation, if I enter only a phonetic first name, then 'Kathy' sorts under 'C' when I add 'Cathy' as the phonetic alternative for the first name.

Google assistant: Integrating support for blind users and help for TalkBack
I am using Android 11 on a Realme 6 device.

I want to know, why is i isn't possible to activate TalkBack by simply pressing the button for Google assistant and saying "activate TalkBack".

I also want to know why it isn't possible to open Google assistant and say, "run a TalkBack tutorial", or, "open the TalkBack help menu" (because the user may have forgotten or may never have known the combination for this, and can investigate all the commands once this is open).

The user may lose their eyesight all of a sudden and may need this information.

Ad it stands, Google assistant gives textual information but does not perform the action, and, if the user is blind, they will have to guess where the button is and what it says at best.

They may also say, in Google assistant, "how does Android support blindness", to which Google assistant should perhaps answer with "through TalkBack".

It would be nice if this functionality were integrated into Android in future versions of Google assistant.

Thanks.

How can I restore swipe-to-call/text in the Messages app on a Samsung Galaxy S22 running the latest version of Android?
I'm sure this was the old behaviour of the Messages app (at least on a Samsung Galaxy S9 running the latest version of Android): swipe a contact's name one way to call that contact, swipe it the other way to text that contact.

Now I can only do that from the Contacts tab on the Phone app; if I swipe someone's name right or left from the Messages app, it archives the conversation in question instead. I can't find anything in the Settings section of the Messages app or in the phone's general settings; I can only find an option to disable swipe-to-call/text on the Phone app.

How do I make Android store user apps on a separate storage device from the system?
(This is yet another question in my series regarding the Firefly ITX-3588J board.)

This SBC board that I have can run Android 12, and has at least two storage options: the onboard eMMC flash chip, and an SATA hard disk connection. What I am trying to do is break up the Android system so that the system software and kernels are on the eMMC, but the user apps and data - usually given as an eMMC partition labeled userdata - are on the hard disk. The idea is to use the board as a small and power efficient non-x86 (i.e. ARM) desktop system.

So what I did was try to format the hard disk so it has a GPT with partition userdata and suitable file system (ext4). Then tried to start Android, and the kernel fails to fully boot, because it can't find /dev/block/by-name/userdata. My thought was that the /dev/block/by-name/ system would contain all partitions of all recognizable devices on the system, but this does not appear to be the case - it only seems to show those on the eMMC.

And yes, the OS can handle this drive: I tried it with the board's stock install where everything was on the eMMC alone, and it could mount the drive. But I wanna get apps on there, and thus need to do this.

How can I make sure the partitions from the hard disk also are show in /dev/block/by-name/ on early boot? How does Android populate this, and what is the "most correct" way to change that so that it will put other devices than just the eMMC there?

FWIW, this board is the first time I've actually ever had to delve deep into the bowels of Android, so there's a lot I really don't know here and much of what I've learned has been through extensive trial and error.

How to "permanently" turn off networking on an android device?
I'm in the process of creating a "secure device" to store and process sensitive information. Using an Android device was the best course of action for me, since I can make a quick app, plus I can use the camera, finger print, and other goodies that comes with these.

But, and where is my question: Is it possible to do it on a OS level? in such a way that there is no obvious way to turn it back on? I spend more than 2 hours searching around but most results are how-tos, or things unrelated to what I want to do.

Just to be clear, I do not want my app to do this, but instead, run a command or do something to the device that "physically" disables connectivity on the device.

I would love if this does not require a custom android build.

I would accept purchase recommendations for devices that comes without connectivity at all.

Thanks!

How to create rooted-rom?
I have downloaded stock-firmware for my Android-TV-Box. I took a while but I managed to unpack the firmware, add some apks to /system/app and repack it again.
It worked but I was a bit confused with root and system-apps. They are not the same...

I have full access to the rom files and can modify all. How can I grant an app/apk root access?

How to add a custom contacts repo to Android?
As an android user, I would like to develop an app that installs a local contacts repo that is in parallel with the Google and Samsung contact providers/repos.

The reason is adding temporary contacts with a TTL. When looking for an apartment, I don't want all these random contacts. When selling something, I have just multitudes of contacts with no names just so I don't save these temps. When calling up moving companies, or any temporary agency ... I do not want these contacts forever on my phone.

How do I create a custom contacts repo such as in manage accounts?

I looked all over for something like this, and I found ContactProvider which felt like the right one, but after reading the docs, it doesn't quite fit. Tried AccountProvider but that is mostly about authorization from what I understand.

How can I add a contact provider such as Google Contacts or Samsung Contacts?

Ways/Ideas to force activate debugging mode on Android (to use ADB tools)

Context

I got 2 Samsungs with broken screens, an A71, and a J5 pro. None of them support MHL, nor Dex mode... (Yes, Samsung restrict such features to their premium lines (with premium prices) even when the hardware is plenty capable to hold 'em). Although, there are some hardware solutions made by some companies that get rid of this unfair policy, as y'all can see here.

Actual problem

Well, the problem is that to make use of such solutions, you must at least have your screen working properly, to do the preps.
I could use some tools and tricks to stream my display, but most of 'em require the dev mode on... and right now I just can't figure out a way to force the system to activate it and be able to use ADB.

Plus: They're locked with PIN passwords and it's kinda hard to hit the password using a mouse, so I'm also accepting suggestions.

How to set calls loud and messages on vibration, both for certain people only?
I need my mobile phone to be quite while being at work, but I want allow exceptions:

I want to notice messages from certain contacts, i.e. for those people incoming messages should result in vibration with no tone. At the same time, I want to hear incoming calls from certain contacts, i.e. I want my phone to ring in a preset loudness. In all other cases calls and messages should be quite. With messages I mean whatsapp.

If possible, I want to define contacts for the message-vibration group and the calls-ringing group separataly. An example: For my wife, I want ringing calls and vibrating messages, for my brother I allow only the vibrating messages but no ringing calls. If this is not possible, I am happy with a solution where I can define only one group of persons that have ringing calls and vibrating messages. I guess for this one-group-solution it is best to use favorites in contacts.

What I`ve tried: I tried the "Do not disturb" option which i quite nice. Here, I set my phone on load, turn on "Do not disturb" and define exceptions, i.e. people who may disturb with messages and calls. The weakness here is, that we can not make calls loud and messages on vibration here. They are both loud or both with vibration in the "Do not disturb" option for the exceptions. Further, I saw this answer but if I was not able to define incoming whatsapp messages of certain people in MacroDoid.

问:
Can't Android phone undo its own formatting (wiping) of an SDcard?
Doesn't formatting just switch a few bytes but leave the data basically still there? But there doesn't seem to be an inbuilt option to do so, is it hidden somewhere or can't exist for security reasons? I'm talking about an external SDcard that just put in.

The android apps on Google play that claim to recover files from SD cards, seem to be badly reviewed and ineffective. Maybe rooting might help but not sure and complicated/risky.

It does seems to be recommended to plug the SD card into a Windows machine and download software to do it that way. But I don't have a Windows machine and how can trust internet cafe or public library computers? Surely it can't be necessary to use Windows to access Android file system settings?

How do I clear Android caches via ADB (Bricked phone)?
I have used my phone and all was fine, but I wanted to reboot it and something went wrong. first it has stuck in boot loop, I waited ~10 minutes and thought it'll boot but no, then I tried enter a Recovery (twrp) and it just doesn't want to boot even in recovery. So I went to fastboot and flashed a new version of twrp, but it still won't boot. All the times when I have been stuck in a bootloop I just cleared caches via twrp and phone booted fine but now I really don`t know what I can do to rescue it and not lose my data. So maybe there is a way I can wipe caches without accessing the recovery menu? =(

If I force bootloader to load from fastboot it throws me back into a fastboot.

Auto factory reset - is this a general function of Android?
I want to install a software provided by my company but the IT admins only accept devices that support the "Auto factory reset" functionality (automatically perform a factory after if the wrong lock screen password/PIN has been entered 15 times consecutively). They claim nearly every Android phone would have this function.

I know that certain Samsung phones have this functionality but Samsung is known to heavily modify Android. So my main question is:

Is or was the "Auto factory reset" functionality ever included in general Android?

I have checked multiple devices with different Android versions running. And except from Samsung no device had this functionality, so I am a bit confused...


问:
Questions on implementation of message/notification light/LED
I hope this collection of questions on Android's "notification light" are not too generic.
Also I hope it's OK to bundle them.
Anyway, here they are:

Is there an API to "replace" a physical notification light by an app, i.e.: make the app "forward" events directed towards the notification light (that is actually absent), also meaning that any other app controlling the notification light would be redirected?

Should a current phone have a notification light (assuming Google makes hardware guidelines for phones)?
My old Huawei Android 7/8 phone had a triple LED (I guess red, green, blue) that could be controlled by apps like signal to light up in different colors (it's also used by the system as well, e.g. to indicate a low battery), but my current Oppo Android 12 AMOLED phone has none any more.
Somehow I miss it.

I noticed that when the camera is in use the display "emulates" a green notification light, so I thought the notification light might be emulated to be used by other applications as well, but seemingly it isn't.
Or is there a setting I need to enable that emulation?
I also noticed that I can "control" the function of the non-present notification light in some apps, but it does not seem to have any effect.

MS Teams Audio issues via Pixel 6
In the last week I began running into an issue. Not sure if there was a system update (could have happened overnight).

In short audio doesn't work in teams meetings until I clear the cache for the app.

Issue occurs with both wired and wireless headphones

Audio will work via phone's built in speakers

Once it is reset it will work for one meeting or a couple. I haven't figured out what triggers the issue

Issue is limited to MSTeams, other applications (music/audible/youtube) work just fine.

So far I have tried:

Restarts, which did nothing

Removal/reinstall of the application, this worked similarly to clearing the cache, it helped but only temporarily

Some local ipv4 hosts unreachable
Periodically some hosts on my LAN (but not others) are inaccessible from my phone, both in chrome and pinging/tracerouting from termux.  These hosts are up at the time and accessible from other devices on the network.  On the phone the hostnames resolve incorrectly when I ping (presumably caching a previous result) and attempts to connect by ip fail as unreachable.  Other LAN hosts are always available.  There is no pattern (yet spotted) in which device becomes inaccessible or for how long.   The phone is connected only to the correct wifi network (dhcp) and there is only one dns server on my lan (which is not the default gateway).

How do I debug this?  ip route in tmux just returns the phone's ip address. traceroute likewise falls back to the phone.  A comment on this question mentions that 'android routing is really complicated'.  How do I find out where the packets are actually being sent?

The problem is annoyingly transient, but if I have some idea what to run next time it happens I might be able to get a handle on what's happening.  It seems to have begun recently, but I've been away for a few months and can't say which upgrade.  The phone is a Galaxy A10 running android 11.

Restore whatsapp Backup in unexpected hidden/inaccessible location
Device: Samsung Galaxy XCover Pro

OS: Android 12

I need to restore a (local) backup of Whatsapp. Contrary to what Whatsapp sais, it is not stored in:

/sdcard/Whatsapp/Databases

nor in

/internal storage/Whatsapp/Databases

Rather, the backups are in:

/storage/emulated/0/Android/media/com.whatsapp/WhatsApp/Databases

The files can be found by the "My Files (v13.1.01.321)" app, when searching for them. But I can't copy, move or rename them, as indicated by the whatsapp FAQ (see above link). Also, navigating to the files is impossible, as the Databases directory seems to be hidden/inexistent. (Tried with "My Files" app, Nautilus file manager on GNU/Linux Laptop and adb shell)

So, how do I restore the back up now? Do I have to "root" the phone?

Thank you very much.

Restoration of TWRP full system backup fails due to /data format
Device: Samsung Galaxy A3 (2017), a.k.a.: SM-A320Y

OS: Android 8

TWRP: 3.6.2-9

I created backups of the following partitions:

Boot

System

System Image

When restoring either of them, I get the infamous error:

Failed to mount '/data' (Invalid argument)

I can make this error temporarily go away by:

Reformatting /data as FAT or exFAT and

then back to ext4

When re-restoring either of the partitions afterwards, TWRP reports success, but the phone ends up in the boot-loop.

Side note: when attempting to repair the /data partition, before the 2 steps above, the error message is:

```<code>/sbin/e2fsck -fp /dev/block/mmcblk0p24 process ended with ERROR: 8
Unable to repair Data.
</code>```

Search results for error 8 of e2fsck are not really encouraging though...

Is there any possibility to

either restore the backup

or read the data in the backup differently?

Thank you very much already.

Malware (?) that opens apps, windows and uses random features. Can't figure out what is going on
So, for a couple months this phone has been doing weird things at random intervals. Scrolling through photos, entering Whatsapp and clicking all the tabs and profile photos, making calls to random contacts.

At first I thought it was some app I downloaded, so I entered safe mode, deleted all the non-system apps except 3, reduced the permissions on those. I also tried to delete, stop, or remove the permissions of the remaining system apps (in case this app is masked), all the system apps that were suspicious got under review.

Ran Avira, Avast and AMD - 0 virus found.

I thought it could be a RAT as the screen is controlled, but the control has no logic whatsoever, it goes from one app to another, calling people, viewing pictures?

I thought maybe this is one of those famous viruses like the early PC viruses and did my research, but found absolutely nothing.

Enable Wifi or Cellular data in Lock screen to unlock Phone

Problem:

my Huawei P30 Pro is locked and I don't remember my passcode as I was using it with the fingerprint unlock for 2 years, which suddenly stopped working. I can prove that it is my phone, as I still have the packaging and the original purchase receipt and I can access the google find-my-phone, where it is shown and I could theoretically unlock it.

However, the wifi and cellular are unfortunately turned off, as I was conserving battery during a hike.

Solutions tried:

I tried to connect it to my router via ethernet and USB-C to ethernet dock, which "worked": I see the <-> symbol in the display, I see the IP address in the router and I can ping it in the local network. It's still offline, as no notifications are coming through and it's offline google's find-my-phone :( Why?

I tried the safe mode menu, but no change, just the safe mode watermark.
I tried to update the EMUI via the recovery mode, it actually connects to my wifi(!) and tries to update, which fails and afterward DISABLES the damn wifi again. During the recovery mode and afterward it still does not show as online on google's find-my-phone.

There are no pull-down menus to enable wifi or cellular on this phone.

Unfortunately, I also seem to not have enabled the Huawei-app-thingy to unlock it, but wouldn't help anyway as I can not connect to the internet.
It's a bit ridiculous why none of these methods worked...

Why does the ethernet not work and of course:

问:
Prevent keyboard from popping up when clicking a text box on Android
We have a Samsung Galaxy tablet running Android 8.1. We use it for inventory. We have a Bluetooth scan gun that goes with it and when hooked up to a tablet it registers as a physical keyboard. It works just fine. The problem is on the website (sage inventory tracker) we use, it has text boxes. You click the text box and scan the barcode and it fills in the information. This works just fine, but the keyboard pops up every time you click the text box which is annoying to the people using it.

I can turn off the show on-screen keyboard so it doesn't come up, but there are times when you need the on-screen keyboard to type things in, so you have to go back to the settings and turn it back on to get that to work.

I was wondering if there was a way to create a shortcut to either turn show on-screen keyboard on and off without needing to go to the settings every time or a way to just manually turn on the on-screen keyboard with a button click or from the drop-down notification bar. I've tried many different things but can't find a way to get it to work.


问:
Can a Samsung galaxy s21 Ultra smartphone be connected to a 49 inch ultrawide monitor?
I want to start using my Samsung galaxy s21 ultra as a computer. I'm also planning to buy an ultra wide 49 inch monitor that i want to display the Samsung screen on using DEX mode. I want to connect the phone to the monitor using a USB C cable.

I haven't purchased the monitor yet because i want to know first whether the builtin video card of Samsung galaxy s21 is powerful enough to handle the resolution of a 49 inch ultrawide screen.

Does anyone know whether this smartphone can handle such a wide screen? It needs to be able to fill the entire screen, not just part of it.

Thanks

EDIT: I'm talking about a monitor having the screen dimensions 5120x1440 or something very similar. Heres an example

WiFi hotspot creation from access point, not mobile data
My Samsung Galaxy Note8 (N950F) let me create a WiFi hotspot while connecting to an access point. Most of the other android smartphones doesn't allow hotspot creation in this manner, only allowing the creation of hotspot from mobile data. What's inside the Note 8 smartphone which is allowing such functionality? Is there any name for it?</p>

Sync SMS inbox and Google Voice
I use Google Voice for my phone, for voicemail and SMS. It is very convenient to read and send texts from my computer, but if I do not use the Google Voice app on my phone (which, unfortunately, is rather ill-designed in my opinion), the texts I send from voice.google.com or the Chrome extension (or, incidentally, the Google Voice app on my phone) do not show up in my SMS thread, in the stock messaging app or any replacement one (I use GoSMS). </p>

<p>Is there a way to make Google Voice sync with these somehow, so I can see the messages I send through Google Voice without using one of their apps? </p>

问:
Why can't I reach other devices on WiFi network that doesn't have internet access?
My phone with Android 11 is connected to a hotspot on my laptop that does not have internet access (on purpose). In the quick settings it shows a little cross next to the WiFi icon, the status bar doesn't show it at all, only a 4G icon that data is active.

Other devices on the hotspot can ping the phone and successfully send datagram packets to it (via a custom app) but the phone cannot ping them and its datagram packets don't reach the network (can't see them with Wireshark).

The only way the phone is able to reach the devices is when I turn off data connection, so it can only route the packets through the WiFi network. Is there another way that would allow me to keep data on so I can have internet access? The subnets don't overlap and I can't think of any other reason the packets would be lost. I believe this is some Android-specific issue.


问:
Why does Android One not have a standard Recorder app?
I thought all Android phones had a standard recorder app so was surprised when I just tried to record an environmental sound and found that my Nokia 7.2, an Android One device running Android v11 doesn't have a standard Recorder app.

Why do Android One devices not have a standard Recorder app? I know there are many available from the Play Store but would have thought a recorder to be a standard app common to all Android devices.

After moving to Pixel 6 Pro, some daily apps are no longer supported
I've recently upgraded my phone from Pixel 3 XL to Pixel 6 Pro.
After some time, I noticed that some are apps are missing from the Pixel 6 Pro. I can't find those apps at the Google Play store, and in the web version of the Play Store it say that they are not compatible with the Pixel 6 Pro:

It's probably not because of the Android version (13), because I know that these apps are available and working fine on some Pixel 5 devices running Android 13.

I thought that maybe it has to do something with the device's screen resolution or DPI/PPI, which the app might not support - but really unsure about this.

Any ideas about what could solve it, without side-loading APKs? Either from the user's perspective, or from the developer's perspective.
