Suddenly the touch screen can do things by itself when I lock and unlock the phone it works as normal it just happens once in a while? Is there anything that can be wrong or is it best just to replace the whole front panel again?
Make sure LCD and digitizer flex cable is connected to his connector.
I had exactly the same problem!!! I tried a lot of times fix it but I could not… After many time, now, I’m sure that is problem with new LCD Screen… I’ll buy another and I will try again. I got back to the old lcd broken and all is working well.
