Is there a way to group notifications by app?

My phone is running MIUI 12.5 (rooted if it matters) and some apps just push individual notifications so each notification I get, shows up in its own bubble instead of showing them all under a group of notifications for this same app.
It's really hard since it takes up all my screen and if I want to search for notifications from a certain app I have to go over all the other notifications from the other apps..
Is there a way to force notifications from the same app to be grouped together in my notification bar?

How to fix the recovery mode error?

When a samsung smartphone is rooted with MagiskHide, how to restore widevine L1?
Using MagiskHide against all Google services and clearing data, I restored the widevine L1 level in the DRM info app. But now, all the video services that are widevine L1 only idle when attempting to play a video instead of properly showing an error message (so it’s don’t work).

Using MagiskHide against all Google services and clearing data, I restored the widevine L1 level in the DRM info app. But now, all the video services that are widevine L1 only idle when attempting to play a video instead of properly showing an error message (so it’s don’t work).
As far I understand, videos decryptions keys are erased from the trusted keystore of the cpu in case the firmware is tampered. If this is true, how to restore them ? If not, how to access apps that require widevine L1 access (not accepting widevine L3) ?
I’m asking this because several post across the Internet emerged in claiming on how to restore widevine L1 and by following them the device is again signaling the compatibility with L1 but doesn’t seem to support it again in reality.

I have a problem with USB tethering on my rooted Nougat phone (LineageOS). After some time phone stops USB tethering. To fix that I run the following script like this:
adb shell
su
nohup sh tether.sh &
exit
exit
tether.sh
#!/system/bin/sh
service list
while true;
do
if ! pidof -s dnsmasq > /dev/null
then
echo -n "Connectivity lost at "
date -u +%FT%TZ
echo "Waiting 3 seconds..."
sleep 3
echo "Calling ConnectivityManager.setUsbTethering(false)"
service call connectivity 33 i32 0 2>&1
sleep 3
echo "Calling ConnectivityManager.setUsbTethering(true)"
service call connectivity 33 i32 1 2>&1
echo "Waiting 3 seconds..."
fi
sleep 3
done
Problem: If I use
nohup my call to service call connectivity fails with service not found. And I put service list on top of the script which returns Found 0 services:. However the same commands work when ran directly from adb shell; su.
Why service call doesn't work inside this background script? Does it need the same tty to work?

Many different root-only actions involve mounting and editing files in the Android
/system directory. Because there have been so many types of Android OSes, rooting techniques, and actual root solutions from the last decade, it has made it difficult to confidently determine if this is possible with my current root solution: Magisk with locked bootloader.
From my understanding, Magisk is a completely "systemless" root solution, so by simply disabling Magisk and rebooting, *all actions performed as root are reverted.* This is important for me because I have verified boot with a locked bootloader via [avbroot](https://github.com/chenxiaolong/avbroot/) , so if there is any change to the system partition then it will fail to boot and the device will be bricked.
So, with Magisk, is there a specific module that is required in order to "write" to the system partition systemlessly, so that it's not actually changing anything in the real system directory? Or does Magisk do this by default, and all I have to do is make my file edits from a shell like ADB root or Termux su, and they will be applied systemlessly?

Removing DRM from Android using root
I would like to know what one would have to do to remove DRM (Digital Restrictions/"Rights" Management) completely from an Android phone that one has root access to. So far, I have thought about removing `/etc/drm`, `/etc/dcmrcm`, and `/system/bin/drmserver`.

I recently upgraded my encrypted Nexus 5 CM11 to CM12.1 and now I need to reinstall Google Apps. Unfortunately, it seems to have lost root access which is needed to install a zip in recovery mode. I am using TWRP recovery, which does support encrypted storage.
Since I can only get root back via recovery mode, looks like I am now in a deadlock.
Anything I can do?

Fonts in Android are kept in
/system/font directory. There seems to be no way to install custom fonts without rooting your Android or installing some apps.
- Why has Google made it almost impossible for Android users to install custom fonts?
- What was the engineering decision that led fonts not getting picked up from ~/.fonts/ user directory as happens in a standard Linux Distribution?
The same behaviour is seen in ChromeOS as well.

Recently, something has happened to my phone's temperature sensor. It's showing ridiculously high values for the temperature (over 100 degrees), even though it's very cold. This has caused my phone to refuse fast charging, and it charges very, very slowly. (~7 hours to charge)
Is there anyway I could turn off a sensor or fake its value so that my phone charging returns to normal?
Or is there anyway to force the phone to ignore the thermal limits during charging? (I know it's dangerous but I have no choice)
Deleting the thermal engine file doesn't fix the issue.

I've tried to root my HTC Desire 516 dual sim by following this guide:

But obviously, I did something wrong. Now, when I turn on my phone and unlock the screen, suddenly there is a message saying "Unfortunately, HTC Sense has stopped", and I didn't make a backup and now don't know what to do. Can someone help me to fix it? I cannot do anything on the homescreen or even to get in the app menu, only in settings menu.
Also, when I try to wipe cache or go for the factory reset it returns a string saying "E: failed to mount/sdcard (no such file or directory)"
I tried to find a stock ROM for this phone but seems that there's none on the internet.

Is in Android there is an available database set for limits display frame rate? If they’re available, is using ADB/Root (Terminal), or how, or even it can't?
I've been searching this for years, and not get an answer yet. Actually, this is for tweaking to trigger any benefits. This like my other phone embedded feature is Xperia STAMINA mode which is it can set the display frame rate (to 2x lower from 30 fps) for battery saving. But... I mean is not only for that. Many others too that can benefit. So, is this can available on a pure Android system? Or this only self-made for manufacture's hardware so that not possible available on others except Xperia devices?
If there are other threads that I don't know. Please let me know. I'll understand it, and try if it makes sense.
