Touch gets wird when the screen is connected to ground
A waterdamaged iphone 5 came in. I removed the shields and cleaned the board with ultrasonic. I replaced the screen and the phone now turns on and works okay. Allthough the touch wasn't great. It shutters and the screen freeses sometimes. It seems to help by restarting the phone, but only for a while. One thing that also solves the problem, is by lifting the screen out of the frame so the screen dosent get contact to ground.
Is there somthing wrong with the screen (i don't have a spare to try out right now)
Or does it short out the board somehow.
