Touch Screen sometimes doesnt work
this is my first post soooo.
Well let me explain the problem here. I bought an iPhone with screen defective i changed the screen and noticed that the touch doesnt work always. Means
I have to lock and unlock again again till it start working but then it stops and i have to do the proccess again. I bought another screen and replaced it again but the same problem stills. When the iPhone gets warm then the touch screen "okay".
Just to know I'm ready to resolder something because im a Microsolder :D
Edit: It is an Orginal Apple Screen from an Working iPhone 5
