I accidentally bootlooped my phone I guess I have to turn back my old os because this one needs to improvement it may have smooth ui and more things but my old os is more stable and make good in games even though its unofficial
I understand, maybe future updates will improve game performance. I don't use the phone much to play games, but if I find optimizing the kernel for the temperature, I'll notify you here

I solved the problem "I think" in other games phone running so good not getting hot I think pubg has some optimization issues
Glad to hear that it works relatively well for you, I guess it could be optimization issues in pubg. I remember PUBG New State running me with frame drops before testing this ROM.

    Yes, other than the first boot after rom flashing, the booting takes about 20 mins, but it eventually does boot up! Once in a while it boots up in a min. I have faced freezing of phone, and force reset too takes up good 15-20 mins to boot up.
    I really hated that thing that why I turned back to stock rom now I am using good lock for customizasion I dont need any roms now and kernel is bad too in the stock rom I am getting better performance on games nothing changes in rom other than animation and looking ( in my opinion ) the rom is good but they have to make a better kernel because kernel has some issues and the gpu option in samsung part is useless

    yes its stable and faster than octavi os

    I installed it and everything is fine, the automatic brightness is activated when I enter the camera, it does not matter if I deactivate it, it is still activated. And the notification of CameraLightSensor remains active

    Sorry if it is not understood, I use a translator.
    You cant disable light sensor when the phone is started and you have to disable gpu throttling in samsung parts otherwise your phone wont open any games or have low fps
