I found that when the Chess app is open on my Android phone (playing a game of chess), the screen stays permanently on. This can drain the battery and cause "burn-in" if the screen is Amoled.
Sometimes I leave my phone on the table or keep it in my pocket while playing, and I expect the screen to turn off after the set time in the display settings.
in iOS version, the screen turns off after sometime, but not in the Android version Why?
