Touchscreen freezes after fall
I own a small repair shop in Amsterdam and recently I came across several iphone 6 with the following issue:
Customer dropped the phone the screen is broken and in some cases not but it freezes and becomes unresponsive after short while after start. It might be completely operational for a few minute at some point it just gets stuck. The phone doesnt get hot or anything.
My assumption is that something gets damaged on the logic board because of the shatter damage from the fall but I didn't find a way to test it.
New screens are 100% working because if I use them on another iphone 6, no problem.
Did anyone else have this same issue? Any possible solution or just a waste of time?
