I tried to turn on my iPhone XS; I succeeded but now that I have closed it again the display works but not the touch.

It doesn't matter where I touch, it doesn't work. The rest of the phone works, however.

What could it be?

  • Connect it to a Mac/PC and do a backup. After that, do a hard restart and see if that helps. If that doesn't fix it, you should take it back to Apple or an authorized service location to look at it. – fsb Jul 15 '20 at 16:37
  • How can I do a hard reset if I can't unlock the iphone? It says scroll up to unlock the iphone and the touch doesn't work – giò Jul 15 '20 at 16:50

There are only two pathways to address this:

  1. Reset your phone. Obviously, you need to make sure you have a backup of your data.

  2. You need to take it in for service. The Apple employee will actually repeat step one (and inform you about making a backup as well).

The digitizer (the portion that detects touch input) has died. Unfortunately, it's no longer a separate components, but it's now glued to the LCD (the portion that displays images). The whole assembly will need to be replaced.

There is a possibility that the logic board malfunctioned and the digitizer and display is still good, but without opening it up and putting hands on, it's impossible to tell - you still have to take it in.

  • Thanks Allan, how can I reset the phone if i can't unlock it with the touch? – giò Jul 15 '20 at 16:50

  • Ok reset as new, I am stuck on the "hello" screen as i can't swipe up... Everything else seems to be working except the touch – giò Jul 15 '20 at 17:25
  • That's why you have to take it in (path #2). The reset brought it back to factory where the touch is supposed to work. If it's not (as yours isn't) it's a physical hardware issue and must be replaced. – Allan Jul 15 '20 at 17:36
