Regarding settings, I have everything turned off. Adapt display is off. Auto-brightness is off. Auto-adjust screen tone is off also.
I know Samsung displays dim if the phone overheats but my phone will auto-dim even if the phone is cool.
What I've found out is that the phone will only dim "permanently" when the screen is about to shut off.
For example: Set the screen shut off to 30 seconds and around the 28 second mark, the screen will dim for a couple of seconds before it shuts off. This is where the auto-dimming will "permanently" kick in. When the screen dims at the 28 second mark for a second, i'll touch the screen so it doesn't shut off. But by this time, the screen has dimmed already and won't go back to the regular brightness. I have to lock and unlock the phone for the dimmed screen to go away.
This scenario has happened every single time. Extremely annoying.
Anyone else experience this?
