Can you make a33 5g kernel android 13 oneUi 5.0 version? Also Im facing touchscreen jittering issue on my a336e while playing games, could you fix that with making custom kernel?

I'll add it to my list

Btw, right now I don't have installed stable TWRP recovery in my device. Is there anyway to install this kernel like other ways?

See post #2

Does this kernel fixes touch problems and does it fully unlock 90 fps on games like PUBG?
also can I use Magisk to flash it instead?
