touchscreen not working

Hi joe001,

welcome to the Apple (user to user). Community.

Re: "my Iphone 13 touch screen suddenly not working ,

i couldn't even reset as the slide button could not slide.

Seems it is more than just the screen. Could the phone be frozen ?

Apple support has articles online that may be helpful.
