Why my iPhone 7+keyboard/touchscreen is nonresponsive
I have an iphone 7+(model A1784) for which the touchscreen/digitiser from time to time is nonresponsive or typing the wrong letters/characters. My iphone screen is not physically or mechanically damaged and it looks just fine. I was wondering if that is a hardware issue or something related to its coding or else software?
