iPad Air 3 screen frequently freezes up and iPad becomes unresponsive for several minutes
My iPad air3 screen frequently freezes up. I force restart and it’s fine for a while. Today I tried to turn it on after being plugged into the charger. The screen remained black. I tried swiping, tapping and even pushed buttons, I heard some sounds and so I kept swiping and tapping, etc. the screen finally lit up. It required my password. This began happening after the latest software update. What can I do now?
