iPhone x touch screen not working?

My iphone x touch screen not working issue started on when I put my phone in ac room for a 2hours and then until now it’s frozen screen

Hi bro, AC Room is not the problem. I have used it in Ac rooms for several hours and days. Issue could be something related to hardware or software. Kindly check with apple service center once. Normally we can try force restarting the iPhone once.

Else visiting apple service center for proper diagnosis is recommended.
