gugulI'm already planning to go for custom kernels. Asus stock kernel is so fkd up that it deliberately limits the potential of R0G3!
It's the same issue which was present in the first beta of android 11. I too am facing this issue and trust me factory reset is no option. I already have tried that. Whatever things you mentioned here, I too am facing all those. Shots getting registered after 1-2sec, randomly whatsapp comes to a halt.
The temporary solution is to go to wifi settings, forget the wifi and connect again. Sometimes it doesn't even let me connect. It will say connecting connecting then nothing 😂.
It started to happen after the recent update for sure. It's no hardware issue or whatsoever.
