iPad Air frozen on Home Screen
My iPad is used exclusively as a communications device for my special needs son, it stays in guided access all the time. Today on waking it, it was locked on the Home Screen, no matter how I have tried to triple click or touch the screen, nothing works. All the icons are grayed. I tried plugging to in to restart, holding down the on button, and even find My device lost activation. Now it’s stuck on a passcode screen but won’t recognize any touch, so I can’t enter a passcode. Also of note.. the battery icon is full but not green… yellow color. Please help me!
