Ipad screen wont work in a strange way
First off all, im lucky i didnt update to ios 10 yet. but i will explain that later. My Ipad air 2 64 gigs no cellular randomly stopped reconizing input on the screen. I'm a student and it was in class. my ipad would not force restart (because the screen didnt allow input i was unable to turn it off normally) so i just told it to the teacher and i would go on. but there was a strange thing. if i used touch ID to log in and then swiped down i could acces the notification center. if i pressed on any of the apps, nothing would work. but if a tapped on the calender widget on a specific item it would take me there. so i just took it home. at home my ipad still didn't work, so i tried to update it. it was the only way that i could restore my Ipad. If there isnt an update, How do i restore it within 1 or 2 hours? (DFU Mode doesnt work because it wont shut down.)
Sorry for bad English.
