I think this is the bug. If the problem is in the GPU the f55 doesn't work properly mine works fine. I also notice lag but only when the phone is warm; otherwise, it works fine
After the Google Play system update, I noticed that at 60 Hz, the Galaxy F55 gives around 6.5 to 7 hours of SOT. Don't know what Samsung is doing with one ui 8.5 and the Google Play system update
Is there any heating problem in the previous version cuz i also use F55, I notice heating and max 4 to 5 hours of sot and in my area, the 5 G is not constant switching between 5G to 4G
You use an adaptive refresh rate or standard 60hz ? cuz adaptive 120hz drain battery due to heat and also 5 G fluctuations to 4 G in poor signal areas.
