How to have text reminder popup when receiving calls from specific contacts?
Use case: I would like to be able to add a note that is displayed the next time a certain person calls. For example when "Joe" calls it shows me a note such as "Joe has peanut allergies" or "I owe him $20" etc.

How can I do this? Is there an app? I have Tasker. I could have Tasker launch my standard note taking app when calls are received but I don't know how it could open the specific note for each person.


问:
Display a user-entered note when a contact calls
In android is there a way to display a user entered note specific to a contact whenever that respective contact calls? Something like this...

For context, it has to be similar to how Truecaller app displays the contact details of an incoming call including name, phone number and location.

Can your method/app/solution be used with VoIP/messaging apps like Signal, WhatsApp, Telegram, Zoom etc?

Notes:

Any solution (app/tasker profile etc) that can be run on a standard Android device is welcome.

Unlike Truecaller app it need not work with phone numbers that are not in user's contact list but user must be able to write notes for
individual contacts in their contact list.

FOSS solutions are preferred.

Solutions that run on non-rooted devices are preferred (for more accessibility)

Can I run a virtual Android machine on my Samsung Galaxy S6 Edge? Or maybe can I run a custom ROM without flashing stock?

Answered by Ash-Ishh

Part 1: Using Multiple ROMs without flashing again and again

App required: MultiRom
Introduction:

MultiRom powerful utility that installs itself into your Custom Recovery.

First Step: "BACKUP" It is recomended to make a nandroid backup of your current ROM in case something goes wrong you can just restore it.

Procedure:

Once you have installed MultiRom open up the app. MultiRom will ask for Root Access. After granting it, you should see Multirom and its current version, the recovery that is required to manage Multirom with, and the MultiRom Kernel (Kexec-hardboot patch)

Just tick all 3 boxes to install Multirom, the recovery patch, and the kernel. Once it’s finished installing, MultiRom Manager should prompt you to reboot into Recovery to complete the installation. Once you’ve entered the Custom recovery, it should complete the installation and will soon reboot itself.

A message will appear saying something similar like the device will boot into the internal rom in 5 seconds, unless you click cancel. You haven’t installed another Rom into MultiRom yet, so you should only see one option to boot into, and that should say Internal. Internal is pretty much your current Rom, or whatever you were using before installing Multirom. If you do not click cancel, your device will boot into the Internal Rom by default, so click cancel in the event you decide to boot into a different Rom.

Now, in order for you to boot into a different Rom, first you have to download the different Custom Roms you want.

ONLY DOWNLOAD THE CUSTOM ROM THAT’S SUPPORTED BY YOUR DEVICE

Note that once you install your Custom Rom, Google Apps and Services will not be installed on it, so you will have to download something called GAPPS (Google Apps) for the respective Android version. so now download the GAPPS zip file.

Once you are back into your device’s Stock Rom, we will be using TWRP Recovery, as it is the default Custom recovery supported by MultiRom. Once you are in TWRP, click advanced. You should see a new option called MultiRom. Click that, and you can configure settings, as well as install your Custom Rom to boot from.

Assuming you now have your Custom Rom downloaded on your device,click “Add Rom.” You will see many settings on the screen. For Choose ROM type, leave it by default, which is Android. Share Roms with Internal ROM, just leave that as don’t share. You can also see where the Custom Rom will be installed to. By default it will list your internal memory, but if you have an SD card, or even a USB Flash drive that is plugged into your device VIA OTG cable, it will be listed there as well. So just pick the destination of where you want your Custom Rom to be installed/saved on.

Click next, and select your source of installing your custom Rom. 3 Options will appear, which include Zip File, Backup, and ADB Sideload. You should have downloaded your Custom Rom earlier in for form of a .zip file, so just select ZIP File. Next, you will navigate to the place where you downloaded your Custom Rom, which most likely will be located in your Downloads folder. So find that and select it. Once you have it selected, you will reach a page where it shows you to confirm flash. So swipe the bar to confirm the Flash, or installation of your Custom Rom, and let it install on its own. Once the installation has ended, do not be so quick as to click reboot.

Click the back button on the bottom right hand side, and head over to the List Roms option from earlier. Then, click on the Rom that you just installed, and click Flash Zip, which will flash the Zip file for that individual Rom. Now, flash Google’s apps and services that you have downloaded now Reboot>system.

You should be prompted with the same interface as earlier when you installed MultiRom where it asks you which Rom you want to boot into. Click Cancel, as we do not want to boot into our internal rom. Now you should see your brand new installed Custom Rom name listed in the Boot options. Click on that, and confirm you want to boot into it.

Now the Custom Rom’s default boot animation should appear, so that indicates you’ve done everything right. Note that this simulates the process of a brand new fresh operating system being booted up for the first time, so the boot process should take a while longer, just wait a few minutes until you reach the device setup screen.

In the case that you want to uninstall MultiRom, just boot back into your Internal rom and head over to the Multirom Manager app, and click on the big trash can at the top right corner, as this just means the removal and deletion of MultiRom. Click on confirm delete, and follow the on-screen instructions for uninstallation.

Prevent built in apps (Messages, Photos) from prompting for updates?
I use an android phone without Google Play store, although I do install OTA OS updates when they arrive. I don't have a Google account set up.

My standard Photos and Messages apps checking for updates, presumably outside the Google Play store, and spamming me with messages like "Chat and text on your computer". These links take me to Google Play store, which is disabled.

Is there a way to prevent apps like these from doing their own software update checks?

This happened on Blackberrry KeyOne and Unihertz Titan, though I don't think it's specific to the phone model.

The specific apps I'm talking about are:

com.google.android.apps.messaging 7.2.204 (Isu_RC02.phone_dynamic)

Install/replace default android audio decoder - Play Hi-res audio
I want to be able to playback hi-res audio files on my device without being tied to a specific application. According to this spec page on GSMArena the device should be able to play 32-bit audio files. But it seems that this functionality was maybe added to OneUI as the same audio files (24-bit and 32-bit audio) playback with static or stuttering on any AOSP custom rom. Even playing back the audio on other phones, like Pixels, result in the same stuttering. Apps like VLC do support these files flawlessly however it doesn't have the same functionality like closed-sourced apps (example BlackPlayer EX). My question is there anyway to replace the default Android OS audio playback engine or somehow add functionality to support these kinds of files? Or is there any way to add functionality to down-mix the files to 16-bit during playback?

Why does blocking of incomming connections via AFWall cut off the network connection?
There are couple of Android firewall apps in the wild, for instance AFWall. It manages iptables rules. Usually for client devices, admins set the default policy for the INPUT chain to block, but when I set that policy for the chain, the network connection breaks. What's the cause of such behavior? Shouldn't it just block incoming connection from the network to the phone? Is it secure to leave the accept policy for the INPUT chain, and hence to allow any device in the network to connect to the device unconditionally?</p>

Missing WhatsApp Media Files
My WhatsApp on Android crashed without warning 2 days ago on 23 September.

When I restored WhatsApp from the Google Drive backup (I have always been regularly backing up my messages), none of the chat messages reappeared.

I deleted WhatsApp and reinstalled it. I chose the reinstallation of backup on Google Drive, but it was stuck at 24%. When I ignored it, WhatsApp eventually reinstalled a clean version of all my chat histories (i.e. all conversations were present but empty).

I deleted WhatsApp again and reinstall it. This time, when it was stuck at 24%, I forced stopped the app, and restarted it. This appeared to work, and I was able to view all my conversations with the messages.

(BTW, over the past years whenever my WhatsApp crashes inexplicably, I will always encounter the botched restoration, which I will resolve by force stopping WhatsApp when it was stuck and all the media files and messages will be restored, with 1-2 days' loss of messages.)

But now, I realised that ALL the media files (including photos, files, voice recording and videos) that I have accumulated over the years were not restored.

While the photos still show up in their thumbnails in the specific gallery folder, they are essentially now empty 0 B files. When I clicked on them, the systems says that the file is either missing or corrupt.
I accessed my file manager and saw a couple of msgstores files, with the earliest of which being on 23 Sept.

I deleted WhatsApp again to restore the local backup but that option was not available. In the end I had to restore the WhatsApp from the latest backup on Google Drive (while facing the same difficulty of it being stuck described above).

The media files are still missing. Now even the earlier msgstores files on my phone of 23 Sept are also missing. Only 1 msgstore file of 26 September is around.

Please help! I don’t have access to all the WhatsApp media files which are very very dear to me! I have been backing up my WhatsApp files regularly and the missing media files very regularly. There must be some backup residing in my phone somewhere.

Any suggestions will be very much appreciated! Thank you!

Magisk to set orientation - Android Head Unit
On Android head units, the orientation typically defaults to landscape.  And has disabled auto-rotation, the screen will always remain in a landscape mode. This effectively means you can't use any software on Google Play Store or other places to change this default because auto-rotation is disabled. I need to change this feature to portrait for custom firmware I have placed on my head unit (using Android 10). I have installed Magisk.

In my attempts to work out how to do this, I have gathered some information, but I have not got enough experience or knowledge to know how to do this. I really need guidance.

I believe in order to do this correctly, this needs to be done at root, and place in one of these locations in Magisk

(1) /sbin/.magisk/.core/post-fs-data.d/

or

(2) /data/adb/service.d/

and the command syntax would look something like this (3)

```<code>adb shell settings put system accelerometer_rotation 0 # auto-rotation, 0 disable, 1 enable
adb shell settings put system user_rotation 0 # actual-rotation, clockwise, options 0[0°], 1[90°],2[180°],3[270°]
</code>```

Source:- https://stackoverflow.com/questions/25864385/changing-android-device-orientation-with-adb

or (4)

```<code>content insert --uri content://settings/system --bind name:s:accelerometer_rotation --bind value:i:0
content insert --uri content://settings/system --bind name:s:user_rotation --bind value:i:0
</code>```

or (5)

```<code>import android.provider.Settings;

// You can get ContentResolver from the Context
Settings.System.putInt(getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, 0);
Settings.System.putInt(getContentResolver(), Settings.System.USER_ROTATION, 0);

Map human-readable permissions to actual permissions (android reference documentation)
How can I find out exactly what permissions qualify for a given "human readable" permission listed in a given app's App Info in the Android UI?

If I open a given App info for an app installed on my Android device, I see permissions listed like

take pictures and video

modify or delete the contens of your shared storage

access precise location only in the foreground

record audio

have full network access

prevent phone from sleeping

run foreground service

change your audio settings

etc

But these are fairly broad categories.

I would assume that there's one or many actual permissions requested by the app that would map into a given category above.

For example, here's a list of the possible actual permissions that would be requested by the app:

https://developer.android.com/reference/android/Manifest.permission

So my question is, for a given version of android, how do I figure out what are the set of permissions that could be requested by an app such that if any one of them was requested, then the given human-readable permission would appear for that app.

Or, equivalently, for a given "human-readable" permission, what is the set of possible permissions that could have been requested by the app that would make that "human-readable" permission appear for the app's permissions?

Is there a reference document anywhere that maps these actual android permissions into "human-readable" UI permissions?

Steps to investigate what is happening to system files
So, I recently got a notification that space was running out on my 128GB phone. Looking at the segmentation then, the system files was taking about 45 GB data while my other stuff was taking around 75GB. Pretty normal so far, and I thought, okay, why don't I move my photos over to my desktop, which I did. Freed up around 15 GB and I went on my day.

However, soon enough, I get notified I am running out of space again. This time, I looked and the system files section was taking around maybe, 60 something GB? I thought, that's strange, I just cleared all my photos. What's going on! So I went on deleting apps. I ended up almost deleting everything, just to find that system will grow to consume it within hours. Feeling defeated, I decided to wipe my phone using the option within settings.

So, all was well with backing up and wiping, and I set up the phone again and all that. All went well until I woke up next morning, just to find that I am running out of space again... I was quite shocked. So I wondered, maybe it's something with the apps I installed. So after the phone was almost non responsive complete because of space issues, I did a second wipe. I restored the back up this time, while leaving out some of my other large games that was initially taking up around 35 GB total. I was suspecting games are usually culprit if something's wrong, but wrong. Storage kept increasing after the second wipe and half a day later, got my storage running out again. Which forces me to do a third wipe.

Before my third wipe, I read online that persistent viruses can sometimes nest within the back up. So this time around, I reinstalled my phone without restoring anything. I also only installed malwarebytes and arrow file manager to explore what's going on. I took the precaution too not to add any google accounts except one and completely avoided wifi at initial set up until malwarebytes is up. And unfortunately, the system file size growing issue still persisted. Within half a day, I got this:

Running out of options here... Any suggestions how I can bust open what's in system files to see what's going on? Or if anyone feels compelled to help me look more into this, I can help provide logs using methods you peeps proposes.

USB debugging is on and it shows up "unauthorized.: I dropped it and broke the screen a couple years ago, and recently fixed it. Either I forgot the pattern screen lock, or (as I've been reading) this phone has whatever bug that causes the device to forget it. I know I can factory reset it, it's just a last option.

How I got from there to here:
I had four accounts on this device. Using the hotspot on my current phone, I changed the hotspot wifi name to an open wifi network I know this phone connected to. And voila! Account Action Required notifications pop up!

Question(s):
I've been using one account as a guinea pig. I change my passwords regularly, and I don't remember which password I was using when it was on this phone, but I do remember every one I've used with this account.

When I get to the right password, will the device authenticate my account and show up again in Find My Device? I'm changing it once every 24 hours and rebooting the phone at random intervals, forcing it to reconnect.

Was the option to override the screen lock by remotely locking your device available with Nougat in 2018? (will that plan work)

I'm just curious if I'm wasting my time. Or is there an easier way to bypass or wipe the lock screen that I haven't found yet. The phone is registered to my LG account, but that f'ing site is so convoluted, I haven't seen a way to do that.

Thanks in advance.

How user apps installed from Play Store get update from Get Apps in Xiaomi MIUI 12
I am using Redmi Note 10 Pro with MIUI 12.5.8 Android 11 running on it. The device has two official application providers, one is Google's Play Store and other is Xiaomi Get Apps. My issue is that, I installed whatsapp from Play Store. Now, it shows that whastapp has an update under Settings-System apps updater-Otherapps, on clicking which will load Get Apps.
I checked play store, and there's no update showing. Similarly, for Zoom app, update available both from Play Store and Get Apps.

Why Fastboot boot Twrprecovery.img hangs loads after 3-4 tries
Question :- Why Fastboot boot Twrprecovery.img hangs loads after 3-4 tries?

I for original backup of Nandroid from twrp  recovery from PC computers I load twrp recovery image in bootloader fastboot mode through command fastboot boot twrprexovery.img but as I run command  the mobile white screen goes to blank black and in pc continuously prompts multiple drives   a dialogue box  to format multiple drives loaded created on twrp mtp (e,f,g,h,j,k) mounted after fastboot boot twrprecovery command. What I think happened twrp crating multiple mtp drives and closing I am have cancel multiple dialogue boxes in computer windows 10.

Other commands used in sequence

```<code>Adb devices
Adb reboot bootloader
Fastboot devices
Fastboot boot twrprecovery.img
</code>```

But after rebooting reconnecting to different usb sockets mobile and trying 2-3 times this  fastboot boot twrprecovery.img it finally display and load twrp image and display twrp menu.. and I took backup and recovery  all went succesful....it means twrp  image is right  and not corrupted and working fine...and for same device

The problem is why it's loading after 2-3 attempt on same usb port same drivers same cable  it happened many time not one time.

Now I am asking as I want to install flash twrprexovery.img  to  recovery partition and wooried that is it problem to image or any thing with  it don't create problem after installing flashing .. how should I install twrp recovery  which command is safe (fastboot flash recovery twrp.img)
Should I install as twrp recovery can be loaded and used with pc without installing but will not run through mobile.

how to install OTA updates on TWRP rooted stock image
I have a stock ROM Android 10 on which I installed TWRP recovery and magisk root

now my stock ROM after quite some time offered an OTA update
,
and it will not install ,obviously ,via TWRP.  my device is type A only ( unlike  A / B type) for which there is this detailed guide which I cannot use.

I then I read about this module
DM verify no encrypt

Questions

-will flashing this module help resolve this issue &  I should be able to install OTA updates seamlessly through my current recovery

-if the former isn't relevant what would be the approach for a Type A phone to install OTA updates other than just restore original stock boot and recovery and once again re install custom recovery and re-root, which is painstaking.

-to install the above-mentioned module should I decrypt my phone which I think is encrypted I have a fingerprint pattern and password lock

additional observations

I could manage to get hold of the update zip and changing permissions  permitted me to open the zip file.

I see two files that attract - in terms of of giving hope that I can tinker this update.zip so that it can install without a verification

updater
found here at this path

/storage/emulated/0/update.zip/META-INF/com/google/android/updater-script
entire script is uploaded here

and otacert found here

/storage/emulated/0/update.zip/META-INF/com/android/otacert
and it looks like

-----BEGIN CERTIFICATE----- MIID2zCCA etc  -----END CERTIFICATE-----

approaches
 is it possible to tweak the Updater script and tell it not to do verification so it can be installed via simple TWRP

the other approach - certificate file that particular certificate can it be changed so that the content matches with the current phone hash. I don't know how to generate one that matches the current  phone

update #2

modified the Updater script and after deleting relevant portions I get this error . this is after two modifications to skip through verification errors which I overcame

original Updater script

modified Updater script used

How to transfer Apps using Samsung Switch?
I am trying to use Samsung's "Smart  Switch" to transfer apps from an old phone to a new phone (both Samsung S9's, both running Android v10). I followed the directions carefully but not all apps are installed on the new phone. In particular, apps I downloaded from the PlayStore were installed Ok, but none of my in-house-developed apps are installed. Is this expected behavior?

Notes:

All apps were successfully transferred (I see them when I tap "Apps") but they weren't installed. Am I out-of-luck?

I can manually install my apps using Android Developer Studio, but I have a lot of them and that would be a real pain.

I tried a "chatting" with Samsung tech support but they were clueless.

Interestingly, when I tried this a few days ago, I got messages saying that the apps were designed for an older version of Android and asked "Install Anyway?".  I always clicked YES but  they still were not installed. I no longer am asked this.

How to fix an incorrect resolution setting without ADB
I'm running Android TV on Lineage OS, on a Raspberry Pi 4. After changing the resolution setting, the connected display (a TV) no longer displays anything but the message "Video Format not supported".

How can I change the resolution setting back/reset it?

I have SSH enabled, but I don't know the default user/password for Lineage. USB debugging is disabled - otherwise I would have done this in ADB.

I've already done numerous searches on the Internet but can't find anything relevant. Will I just have to reflash and start again?

问:
How to make rsync save a huge file entirely?
I have tried to sync from a Linux device to Android device using Rsync Wrapper. The source file size is about 6 GB. But the problem is that the file manager shows the destination file is much smaller. There is enough space. I use --append-verify for rsync, and sometimes the resulting file just gets smaller after retry. Logs seem to show that it loaded what was expected anyway.

Rsync Wrapper version is 1.9.8 rev.27. Android version is 9.

I also tried using rsync (version 3.1.2, protocol version 31) directly over USB with MTP protocol.
I had to delete the destination first, because AFAIK --append-verify does not work with MTP. Still the resulting file is too small, 1727886774 bytes reported by ls -l. I got that size before, too. Again, the log shows that the whole file was sent:

```<code>2021/10/03 09:23:23 [28652] sent 6,024,324,598 bytes  received 588 bytes  5,591,021.05 bytes/sec
2021/10/03 09:23:23 [28652] total size is 6,022,854,070  speedup is 1.00
</code>```

I renamed the old destination file and tried copying in file manager. Again, copying stops at 1.7GB. File manager reports libmtp error.

Fdroid apps seem to lack permission for SD or sim card (outside of phone storage)?
I have a rooted Razer Phone 2, and I'm attempting to slowly degoogle. I'm finding some of the apps I've downloaded from fdroid seem to have access (permission?) issues for the SD and/or sim cards, where I have things like my contacts and pictures stored. If I use the google-based apps, there seems to be no issues. I was able to import my contacts .vcf in my contact app (simple mobile tools), but I can only save them to the phone. It states that other programs will be unable to then read the contacts -- attempting to save on the sim pops up with a very quick error message that is replaced by "import failed". I tried to get a video of it via my roommate's new Pixel (as of June), but because the phone sort of "flashes" and lightens the screen, the video attempts to adjust the exposure and it's lost.

I'm not really great at android, but it seems like it's a permissions thing for me. I attempted looking into the /system/etc/permissions/platform.xml file like this site states, but I suspected (and was correct) that my Termux wasn't going to be able to save for permission reasons. Additionally, my File Manager (gitlab.com/axet/android-file-manager) doesn't allow me to alter file permissions.

Any suggestions on how to proceed? Am I even on the right track here?

Cannot Save Any WhatsApp Data Including Backup to Gmail/Google Account
Recently I bought a new phone (phone Y) - originally, I had been using WhatsApp as a dual app on someone else's phone (phone X), with a number whose SIM card was on a different cellphone (Phone Z). I was messaging people on phone X using the SIM card of phone Z, but when I saved contacts I saved it to a Gmail account instead. All was going well.

Then I wanted to switch over to using WhatsApp on Phone Y. As popularly advised, I went to the dual app on Phone X and backed up the data to Google Drive on my gmail account, but it never notified me of a finished backup. When I deleted the app on Phone X and installed it on Phone Y (which already knows and is linked the Gmail account), I keyed in the number of Phone Z (did not move the SIM because its not a microSIM, as required by Phone Y) and then it asked to give permission to access Google Drive for the backup. I gave it permission but then it said, no backup found.

True enough, I checked https://drive.google.com/drive/u/0/backups and it said there were no backups. I then got suspicious and checked my Google Contacts too - turns out it hadn't saved any of the contacts there either.

Which means the app was never importing any data to the google account, and still won't. Does anybody have any idea why this is happening??

Can Windows 11 synch data with my Android 'phone?
It seems that Windows 11 can run Android apps.   This could, possibly be a major breakthrough, if ...

Until now, I choose apps, such as the TaskCoach to-do manager which run natively on both Windows and Android, then I use DropBox to synch the data files.

Recently, I had problems with this approach, which I won't go into here.

My question is whether the new Windows 11 will obviate the need for DropBox by synching data files between devices, allowing me to add or remove TaskCoach to-dos on one device and have that reflect on the other (e.g laptopn / 'phone).

Values of successive wait durations for unsuccessful Android pattern tries
On my smartphone running Android 9, the pattern lock seems to work the following way:

The user is allowed 5 attempts to draw a pattern.

If all patterns in (1) above are incorrect, the user has to wait time t1 before they are allowed to make other 5 attempts.

After time t1, if all the next 3 attempts are incorrect, the user has to wait time t2 before they are allowed to make other 5 attempts.

After time t2, if all the next 3 attempts are incorrect, the user has to wait time t3 before they are allowed to make other 5 attempts.

And so on...

From my experiments, I know for a fact that the values of t1, t2, and t3 are 1 minute, 10 minutes, and 30 minutes respectively. My question is, is there a manual that lists the other next values for t4, t5, t6, ..., tn? Or, perhaps, is there a way to calculate them?

Also in the storage analysis sections, a lot of space is marked under "Others" (~18 GB out of 64)

The device in question is a POCO M3 and is running on MIUI 12.0.7.0 (Stable)

I'm trying to get google play store to work on a proprietary custom ROM. I was given a hack to do this with my device. It's very hit or miss but I can get it working sometimes.

问:
Two same stock Samsung phones, different apps?
So, I got to install two Samsung Galaxy S8+; then should have been refurbished and wiped, and flashed with stock firmware.

One of them did not have the latest OS update (via Settings/Software Update) - I updated that, now then both show the same (Current version: G955FXXUCDUD1/... strings are the same)

What irritates me to no end, is that these two devices, that should otherwise be identical, show different default stock apps installed. Noticed this before trying Google Play update - and the situation is the same after the Google Play update (done without logging in - via the three dots menu in upper left corner on start screen).

Exclusive to one phone are (via comparing Settings/Apps list):

Briefing

Smart Switch

... and exclusive to the other phone are:

(Google) Drive

Duo

Google Play Movies & TV

(Google) Photos

upday

How is this possible, and why does this occur?

Again, note that I'm talking about both being refurbished, flashed with stock ROM, no root, and presumably no "manual" installing of apps...

Could Samsung have "pushed" these apps, depending on if these phones were originally sold through a carrier?!

(I just noticed now, that in Settings/About phone/Software information, all data is identical for both phones, except for "Service Provider SW ver.", one of which is SAOMC_SM-G955F_OXM_ROM_PP_0014, and the other is SAOMC_SM-G955F_OXM_NEE_PP_0015 ... I guess this has something to do with it - but what is it?).

FB Messenger App notification not showing up / coming through when phone is locked, then all coming through same time, only when app is opened
I don't know if an update occurred, but a number of days ago now (maybe since the FB outage), my FB Messenger messages on the Messenger app (not the Facebook app, or Facebook for Desktop) are not coming through when my phone is locked and the screen is off for awhile (even like 15 minutes or something). When I unlock my phone I don't even get them. It's only when I open the FB messenger app that all the notifications come through and pop up at once . It seems to only be FB messenger that's affected. I get Google Calendar Reminders and Text Notifications. They are coming through immediately and just fine on Messenger.com and Facebook.com .

Completely cleared the cache/data for Messenger and uninstalled/reinstalled the program. Makes no difference. I haven't changed any battery settings or restricted anything. Do not disturb is not on.

Is anyone else experiencing this?

Wi-Fi disabling itself when SIM card missing
Recently, I removed the SIM card and will use the phone for Wi-Fi access only. But Wi-Fi keeps turning itself off without warning! The issue is resolved by entering settings and re-enabling Wi-Fi.

The problem is repeatable: The phone remains connected for some time, and can be used without issue. Some time later after stopping use, Wi-Fi will have become disabled. I am unsure how long after stopping use before Wi-Fi is disabled. My estimate is around 60 minutes, but it could be variable.

How do I stop Wi-Fi from disabling itself?

After 6 months of use the phone died while using it.
It was dead but after ODIN stock flash the phone boots up but the screen is frozen at the first logo SAMSUNG M31S powered by android even though the phone boots up to the system and I can see the screen via Vysor app on my computer.(used talkback to finish samsung setup google sign up etc, enabled usb debugging and I was able to use Vysor to see the phone's screen. When the screen goes to sleep or I press the lock/power button the screen goes black but it won't come back if button is pressed again(talkback says the screen off screen on when pressing power button but the display doesn't' respond, I have to force restart it and its the same issue all over again stuck screen on logo but works just fine touch too.
After the bootloader was unlocked the phone's screen is stuck at the "your device' bootloader is unlocked.... presss power button to continue)it boots just fine but screen is stuck there!(if I lock the bootloader the screen would get stuck at first samsung M31S powered by android screen instead.
Download and recovery modes work just fine and they are displayed correctly but booting to system  just frozen screen at startup and fully functional phone(calls, touch wifi everything)
I tried flashing stock firmware multiple times with nand erase and re partitioning doesn't help.

I was able to install twrp recovery(unlocked the bootloader OEM unlock...) and it does work. But no custom roms exist for this device yet, so I can't try those.

问:
All connections insecure, unable to connect over WiFi except for Google-hosted web sites - possible causes?
Recently I have been having this issue and it has become a real pain that is almost constant.

I can use Google Search, YouTube etc. in the web browser (Chrome and Firefox). However if I try to access anything else I get that it's unreachable. The thing is the web sites (notice the plural form!) are all reachable and I can access them if I switch to LTE instead of using the WiFi connection at home. In addition I have also noticed that all the pages are insecure connection, which should not be the case. Last but not least I can enter web sites (not hosted by Google) via the app that shows stories (news snippets - can be accessed on a Moto G by swiping left to right when in home screen), which is powered by Chrome.

The web sites are all secure and with my laptop (WiFi) I have no issues accessing them and viewing the certificate information.

I tried flushing the DNS host cache via chrome://net-internals/#DNS but nothing changed. I don't see any indication of incorrect system time. I'm out of ideas.

The issue was "solved" by modifying the WiFi connection and setting it to static IP address along with a manually entered gateway and DNS. I don't mind adding my phone as a static IP in my router but I would rather know how this situation occurred so that I prevent it repeating on other devices. In the end there is a solution that goes around the problem and a solution that solves the actual problem. I am interested in the latter.


问:
SMS sender ID does not identify inbound SMS numbers with (9)
I live in Argentina.
Whenever I receive a phone call from +54 11 xxxx-xxxx and I have that number associated with Roger in my contacts, Roger is identified.
But if I don't pick up for whatever reason, I get an SMS reporting the missed call.
The number which originates the SMS is reported as +54 9 11 xxxx-xxxx, and Roger is not identified.
If I add +54 9 11 xxxx-xxxx as a number for Roger, the SMS ID is correctly updated, which confirms the SMS app has access to my contacts. I shouldn't need replicating the number for all my contacts.

Currently using Android 11, Samsung S10e.

This was working fine in my previous Android 8, Samsung J7 prime, prior to my Smart Switch.

See details below.

How can I fix this?

After trying this I realized the problem was the extra 9.
I didn't try syncing numbers stored in the phone with my Google account as here (and I am not sure my problem is the same as that other). SMS ID should not rely on Google, and I didn't need that with Android 8. I guess the OS (or the app?) should take care of that.
(related)

More details

How this was working before the phone switch

I was using a Samsung J7 prime with Android 8, with the same sim card and mobile provider as I use now.
I am right now checking in my old phone a message that I received, with number +54 9 11 xxxx-xxxx, and SMS ID is correct.
The same message, in my new phone (transferred via Smart Switch) is not SMS-IDentified.

How are phone numbers built

Phone numbers are built as +(Country) (Area) (Number) as usual, with a possible extra 9 after the country code, or a possible extra 15 after the area code.
The historical reasons for those extra numbers, and when were they mandatory (calling from abroad/within Argentina, phone call/SMS, calling from mobile/landline, calling to mobile/landline, etc.) are a separate issue. These rules kept confusing people, in particular foreigners. Nowadays networks are smart enough, the rules are mostly (I wouldn't dare saying 100%) not needed. You could also use +(Country) (Area) (No.) from within Argentina; before, that was not allowed, 0(Area) (No.) was needed from within Argentina. I am not certain, but I think even (Area) (No.) works. This is similar to what happens in other countries.
Related: https://en.wikipedia.org/wiki/Telephone_numbers_in_Argentina#Inbound_SMS

So if I call using +54 9 11 xxxx-xxxx, it will likely work well, the same as if I use  +54 11 xxxx-xxxx or 011 xxxx-xxxx.

54: Argentina

9: Prefix for mobile numbers

11: Buenos Aires

xxxx-xxxx: phone number

Then there is the issue of Caller / SMS ID for inbound calls and messages.

Best way to lock down Android tablet?
We're deploying a number of Android tablets into the field next year. Ideally, we'd like them locked down somewhat so that the users can only access certain apps and settings. Configuring a restricted user seems to work, but in the event the device is shut off or rebooted, with newer versions of Android (and the accompanying default encryption of the internal storage), a full user has to be the first to sign in before a restricted user can access the device.

What is currently the best way to work around this? My first preference would be something directly supported by the OS, but I also see a number of "kiosk" apps out there.

I'm currently working with a Samsung Galaxy Tab A7, if that matters.

Flash_image clockworkmod recovery for Samsung Fascinate
I have a Samsung Fascinate for a while that I've wanted to flash a new rom to, but the USB port simply will not work on any PC. I've tried it on 6 different PC's with a mixture of XP / 7 along with numerous installations and reinstallations of the Fascinate drivers. It charges but will not be recognized by the Windows, Odin or Heimdall, so I've given up in that respect.

However, the phone IS rooted. I know this because I can give su permissions and I'm seeing the # in the terminal emulator. So I would like to know if I can get clockworkmod recovery onto it through the "flash_image" command - I've seen tutorials for other phones that are able to do this.

However another problem is that I can find no .img Clockwork recovery files for the Fascinate anywhere. I can find the .zip that's provided on Rom Manager's website (and also the .zip downloaded by Rom Manager itself), but I'm not sure if that's the same thing as a .img.

So my question is, can I flash a .zip as a recovery image? If not, is there some kind of directory of official Clockworkmod recovery .img files, or at least one for the Fascinate somewhere? If not, can I take a .tar or a .bin and somehow mess with those files on the Fascinate without having to utilize Odin / Heimdall?

Thanks a ton!


问:
How does one properly install and run the google play store app on a xiaomi redmi 7 pro that was bought in China?
My cousin has a Xiaomi Redmi Note 7 Pro, Android version 10, MIUI version "MIUI 12.5.1Stable 12.5.1.0(QFHCNXM)" (409dpi) that he bought 'to be delivered from China'.

He recently accidentally deleted the google play store app. When we started trying to fix the problem we first tried making a backup and resetting the device to factory settings, but I misunderstood part of the backup process and skipped a step (i.e actually transferring the backup files to my PC).

The phone was essentially reset without existing backup. Afterwards my cousin tried (without me) to blindly follow Youtube videos that claimed to demonstrate how to install the play store app. I am unable to understand most of those videos since they appear made for audiences that speak asian languages. Afterwards the phone did have the app (as far as I have been able to follow it was downloaded as APK), but it always crashed into the background directly after opening it. Since installing Google Play services (also as APK, 480dpi/ARM64/android10+), the store does no longer crash but also does not react to clicking "sign in" or in any other way.

Sadly I am very much less than a novice when it comes to handheld devices and anything involving them. I do not know how to proceed, but I do have access to my own phone (Huawei P30 lite, model MAR-LX1A, android version 10, EMUI version 10.0.0, decidedly NOT bought in China) with its own Google play store, in case I need a second device for fixing this problem. It may also be simply necessary to tell the device "no we are not in China right now, actually running a google app is allowed you know?" - which should be a software problem, which is about all I know about that.

How to extract data from app?
So I want to switch pedometer apps but move over my data.

I thought I could just get the database, extract the relevant entries and inject them into the other app's database. But no.

First off adb backup does not work, files are 1-4 kB. Possibly to do with my custom ROM.
Also no relevant data in /sdcard/Android/data/com.name.
It will sync with google fit but not historical data.

I located the databases in /data/data/com.name/databases but the ones I could open had no relevant data. The ones I couldn't open (requires some password) were .workdb (no clue what that is) or .workdb-wal, these are ~90 kB so it might have the data.

The app uses google sync. I thought maybe I could get at the data there but was unable to find the backup in drive.

Any  ideas how I could get at the data and then inject it into the other app?

How to cure Battery draining and lagging problem
Question How to  cure Battery draining and lagging  problem

I have lyf water 7 ls-5504 mobile it's been rooted through super user to use link2sd and link apps. But before rooting it's have huge proble of draining battery it's battery drains 25% within if screen off to 10-15min from 100% to 75% very fast. One day it got battery calibration problem to it showed 0% and still it was working... Then I went to sevice center and they formatted and installed th android 5.11 stock rom again they electrically tested  said battery is okay but software problem or may be software draining it.

As I  googled and founded that some softwares setting consumes battery and to find them and kill or.force.stop.them and to cha he settings... Which switch off did ie. Developer option> windows animation scale / transaction animation scale/ animator duration scale

This option and GPU rendering I turned off and Bluetooth WiFi off and background process limit to 2  in setting developer options  which reduced the battery draing in off screen but still while using its

draining to fast in compared to same company other model with same 3000mh battery.

So after rooting I installed  greenify and accu battery to solve the battery charging or draining  problem still it's same.

I tried to hybernate through greenify app  one or two apps which are silently memory resident    but I can't restrict system (google.play services) so I screenshot the developer option process stats  to refer you apps running in memory

From above photo I have given to give reference how much mh or percentage battery is consumed in charging and discharging . If any expert can find the reso. Or app of its draining battery fastly and second phone hangs lags and respond to late and stuck in browsing many times  and many time I have to close all running apps and restart them again. Is it due to rooting or.permissoon apps or link2sd apps or due to accubattery or greenify.  As link2sd accubattery or greenify is no where in process stats ... I had not linked or moved system apps or random used apps  to external sd card..

Now if u can help or advice.me how to redicate or troubleshoot or find the app which is draining the battery or hanging or lagging . The phone....any more reports or details required for your refrence I can send screenshot ...any opinion advice to solve help will  be welcomed

How to disable auto restoring of non-removable applications in Android 10?
I have Android 10 in my Samsung A12. There were about 10 applications that had to be installed by phone producer in the country I bought that phone. Using ADB and command pm uninstall --user 0 ... I removed all this garbage and was very glad. However, when I connected internet Android showed me message, something like "restoring preinstalled applications" and restored all applications I removed.

How to disable this auto restoring?


问:
Auto Reply set up on Google Messenger - How to set so doesn't reply every time same person replies
I have linked our Google Messenger to auto-reply via email as we are a doctor's office and the messenger is not monitored for canceled appointments.  The problem is we ask people to reply "Y" to confirm their appointments - sometimes there is additional messaging back and forth if we are in the office.  The auto-reply runs every time someone texts (a conversation).

Is there a way to have the auto-reply only send 1x to the same number if having a texting conversation instead of every time a response in the same conversation is sent without blocking the number because that defeats the point of auto-reply?

Mount ext4 formatted sdcard on Lineage 18.1
I currently have Lineage 18.1 (20211007-microG-pioneer) loaded on a phone with Magisk 23. I have tried inserting an sdcard that has an /dev/sda1 partition formatted with ext4. In the past I've used the Magisk addon "Vold - exFAT/NTFS/EXT4/F2FS Support", however I now get an "Only support Oreo 8.1" when trying to install it.

Is there any way to get ext4 sdcard support on Lineage 18.1 (fully rooted).

问:
What's the write endurance for the storage of an original Google Pixel 128 GB?
I recently got ahold of an original Google Pixel XL phone so I could upload my large collection of photos and videos to Google Photos without having to (repeatedly, permanently) pay for a storage plan. The battery has been recently replaced and is in great condition, and am planning to take steps to ensure its future endurance (only charging it to 80%, using a slower charger to reduce heat, etc.).

Another thing that concerns me, however, is the endurance of the storage. As some of you may know, flash storage can only be rewritten a limited number of times before it wears out and becomes unusable. (This is why typical, low-cost memory cards fail quickly when used in surveillance systems or dash cams, due to their repeated writes.) I specifically sought out a 128 GB model over the more typical 32 GB model because, by its nature, it has four times the write endurance (as the data now spreads out over four times the memory cells).

However, I'm wondering what exactly this write endurance is. How much data can I write to an original Pixel XL 128 GB before its storage chip eventually fails? In other words, how many terabytes of photos and videos can I back up using the phone before its storage fails and I have to get another one?

问:
How to remove app shortcut from home screen (modded trebuchet launcher) after installing as system app
This tablet is proprietary, so the launcher is custom (modded trebuchet) and very limited. It runs Android 8.1.

I was able to get apex launcher installed, along with root access, but I'm trying to avoid using a third-party launcher because if I rename it with app cloner it tends to glitch out.

The goal is for my exploit of this tablet to be as undetectable as possible, which is why I am renaming all apps I've installed.

I noticed that system apps don't show up on the stock launcher home screen, and since I can't use apex or some other launcher, I figured I would install all my wanted apps (Facebook, telegram, etc...) as system apps.

I was able to install them as system apps with lucky patcher, however they still show on the home screen.. Any ideas for how I can modify the system under the hood, or otherwise, and keep these apps from showing on the stock (modded trebuchet) launcher?
