Some of my iPhone or iPad keys or screen taps do not work - is my screen faulty?

How to diagnose patchy iPhone screen.



If you find that when typing, one or two keys do not work, or some screen taps do nothing, it is possible that part of the screen is unresponsive.

First thing to try is turn the screen to Landscape mode. Do the keys work now?

If the same keys do not work then it is probably software so try a Forced restart

If however those keys now work in Landscape then there is a good chance that part of the screen is unresponsive to touch.

Here is a simple test to try and find "bare patches"

Open a Note in the Notes App

Tap on the Markup Pencil icon

Select a broad tip with a dark color

Scribble lines all over the screen

If the suspect part of the keyboard or screen is near the bottom you may have to do the test again but in landscape (both ways round)

If you see a bare patch then there is a good chance that part of the screen is faulty in which case you should arrange a repair iPhone Repair - Official Apple Support

or Contact - Official Apple Support

Anything other than Screen or Battery may be a replacement phone and the price is in the article under "Other damage"
