[Samsung Galaxy A21s ROMs, Kernels, Recoveries, & O] Zainullahk1234:
What is this?

Pixel Experience is an AOSP based ROM, with Google apps included and all Pixel goodies (launcher, wallpapers, icons, fonts, bootanimation)

Our mission is to offer the maximum possible stability and security, along with essential and useful features for the proper functioning of the device

Based on Android 12.0 (11 is available but 12 has no difference in terms of issues and is faster an the better ui and everything else of course)

Disclaimer:- This will void warranty.

You will need to unlock bootloader.

*All your data will be lost*

Read all the steps correctly

(NOTE: do not apply the fixes if a bug does not affect you)

BUGS:- bluetooth ear/headphones do not work workaround- ( go into phh treble settings misc features and enable force-disable a2dp offload (thanks to @Lil_Boudy for figuring it out!)

If bluetooth crashes your system disable media recommendations under Sound & Vibration > Media > Show media recommendations

mtp not working (mtp does work in twrp and in some custom kernels the one linked here does not fix mtp as it is not changing too many things compared to other custom kernels which brick some phones)

sim 1 incoming and outgoing does not work (you can revieve calls and call but you wonth hear anything nor will your mic go trying to fix) (workaround is to put your sim into slot 2) (i have heard that other people dont have this issue so i guess try your luck)

DO NOT let the phone die of battery you will not be able to boot you can get back by holding volume down and power (workaround- in magisk install acca https://github.com/Magisk-Modules-Repo/acc and install this apk after installing https://github.com/MatteCarra/AccA then set profile to default (this will shut down the phone at 5% hence removing the risk of your phone not booting after hitting 0%

Increase performance without any battery impact or (by feravolt and gloeysik)

Step 1

- Uninstall ANY OTHER KERNEL MANAGER app including smartpack/Ktweaks to avoid conflict, since this app uses AI and machine learning to dynamically boost performance when needed

- Install FDE AI Magisk Module to make it a system app, thus it will work better and removes all kernel locks from OEMs (I'm looking at you, Samsung) https://github.com/feravolt/FDE.AI-docs/releases/download/12.4.1m/FDE.AI-as-system-app.MAGISK.zip

- Update FDE AI to the latest version by downloading the latest APK here, since the fde ai magisk module will only install fde ai 12.4.1, not the latest version: https://github.com/feravolt/FDE.AI-docs/releases

- Move to the bottom of the screen and select AI Chat, then type /advancedai (no space, no uppercase letters). This will going to make the AI more effective, without you having to do anything.

- Go to the settings tab and use the AUTO settings for FDE AI.
