Why is the touch screen unresponsive?
I dropped my iPhone 6s and cracked the screen. Brough it to the repair shop to get it replaced. After replacement some of the letter "n" and "j" are unresponsive.
The strangest thing is that quite often the touch starts to do things itself. It goes into apps and opens messages itself.
Is this most likely a faulty digitiser or could it be something else ?
Is this a good question?
