Why Is The Touch Screen Not Working On Ipad. It has a Docked and an UnDocked Mode. You havent unlocked your device in more than 48 hours.
Remove any cases or screen protectors. Open Settings from your iPhone. If your iPad has 3D Touch then you can check the sensitivity settings and see if that makes a difference when you are attempting to tap the screen or swipe your finger across it.
If the touch screen still doesnt work then move on to the Advanced Fixes.
Reset Your iDevice If you cannot restart your device then you can try this method. You just restarted your device. Swipe up from the bottom of the screen to bring up. The Docked Mode places the Keyboard at the bottom of the screen and the UnDocked Mode places it at the middle.
