My iPhone XS Max is cracked and top row touch isn’t working. If I get a new screen would it help. What should I do??
You only know when you try, the first thing to start is place a good known working screen on the device and see if it solve the problem. You also can try to take it in to a repair shop a ask if the will put a other screen on your iphone to see if that is why the top doesnt react to touch.
