iPhone 7 works great but sometimes the screen goes greay/black
I have a issue that i havent heard about. My iphone 7 hade to have a new screen so i had that put in. After A day or to the screens started to have it own life. Now maybe once or twice a day the screen goes gray/black and is it until I press the off button on and off and it starts to work fine again.
The screen is working fine and i have tried using an other screen thats working on an other phone and the problem keeps happening.
I dont think it is the backlight when the phone dosent go all black its in grey color.
Anyone had the same problem?
Ist dies eine gute Frage?
