    Disclaimer: I haven't tested out any builds but there are testers on our Telegram group. Be sure to backup your boot partition before flashing.
    Many thanks to the testers. It wouldn't have been possible for me to release this if it weren't for them

    -rc builds may or may not be stable and need more testing



    Details:
    • Based on latest Samsung open source drop​
    • Compiled with the latest Clang from Google (Clang 12)​
    Instructions:
    • Assuming you have a custom recovery installed, simply download and flash the kernel zip. This kernel uses Anykernel 3 so no need to reflash magisk(if you use magisk) after installing it.
