Firstly,my a12 touch is not working when it is on a flat surface.secondly,when i increase or decrease the brighteness there are glitches like black lines on display like the display is faulty.
Apna youtube open karay or koi bhi video ko landscape mode full mode par karay or phir brightrness ko tazey se increase or decrease karay?do you see lines or some screen glitches?
