iPhone X Software Problem
My iPhone XS Max suddenly shut off while I was on a phone call. After it shut off it turned back on and was running very slowly. I can't get apps to open and I cant seem to do anything on the phone. I have tried to restart multiple times put that does not work either. I tried to update it but the phone will just shut off before the update even starts. I tired plugging it in to my computer and reseting it that way, but it will not sync to my computer. I have tried everything I can think of my nothing will work. I need help.
iPhone XS Max, iOS 13
