Instructions

???????????

Oxygen Kernel is based on stock Samsung source code taken from Samsung Opensource Release Center with sole aim to provide better performance, stablity and battery backup than stock kernel. A kernel tells the hardware in your Android device how to behave, kind of like your mommy tells you how to behave. You can modify how fast your processor runs by over or under clocking it or optimize your system for battery life.

Oxygen Kernel is always up-to-date with latest patches from kernel.org

Known for maximum stability and smooth performance

All the Source Code is available on github

Warning​

: ??If you come from some other custom kernel or have any issues, you should dirty flash your ROM before flashing Oxygen Kernel to avoid problems.

Reflash ROM -> Flash Oxygen Kernel --> Flash Magisk if you want to root

If you are upgrading between Oxygen Kernel versions, just flash the kernel zip. Also uninstall or clean data of any kernel control app you're using.

????????????????????????????

Going back to stock: You can backup your boot.img with TWRP before flashing Oxygen Kernel and restore the backup whenever you want to revert.

????????????????????????????

1] This kernel removes forced encryption, if you face "encryption process failed" error upon reboot then you need to format /data. This is generally needed if you are installing this kernel on stock tw rom.

2] In OneUI Pie ROMs you may get a warning at boot saying "There's an internal problem with your device". You can safely ignore this warning and causes no harm. It's due to some mismatching KNOX/mobicore stuff. I'll fix it soon.
