Black box on screen
After using FaceTime on my IPad, I see that a black box has suddenly appeared on the screen. The solid black box has three circles/icons along the bottom: a zoom icon, a red circle with a white telephone and a video camera with a horizontal line through it. If I tap inside the black box, the 3 icons disappear, only to reappear if I tap again. I’ve gone to Accessibility but nothing is turned on. I’ve tapped the screen 3 times, and clicked the Home button 3 times. Nothing happens.
Please help me!
