Ok, little update. Cause devs dont find time to be of assistance here, I decided to execute a factory reset, no backup, pure reset. After this I installed my usual apps from scratch. One thing I changed is no enabling developer options. In my surprise phone back to fast and crisp response yeah... Till next charge and now stattering and lagging during transitions is back, slowly incrising. Were talking 60Hz here. When I change to 90 or 120 it helps a little, but still not even close to what performance looks after... Simple restart. One again, help please because this issue is rendering my phone simply useless.
