You are lucky , did you dirty flash over last update ?? Me here the setting always revert back to always on even tho I turn it off or put it on automatic... And I'm not alone so I'm trying to know what you have made that we don't .Working normal here
You need to back up all your data off the phone, boot into TWRP, then go to wipes, and "FORMAT DATA", acknowledge acceptance by typing "yes" ( without quotation marks).Please Help me!
I have mi 8 Unlocked. TWRP installed, but I when install weekly ROM 9.2.21 the phone stay on screen ANDROID and three dots blinking...
The phone was 10.2.2 Global Rom
For several last releases of MIUI ROM I decompile the File - com.android.documentsui, add the Russian language and recompile the application.
My suggestion, would you install it as if it came from the factory, doing a clean installation, making a wipe, including FORMAT DATA, you will lose all the files, just so you will be sure if it was a bug or hardware problem.the problem persirst also after clear the theme. i think is problem of screen and not software
