I don't use any accessibility features. These have always been turned on...and are turned off now. So, today while out driving around testing the LTE on my Verizon 4G iPad, I was pressing near the home button. All of a sudden, the screen was magnified or zoomed in. It was like 1/4 of the entire desktop was zoomed to fit the entire screen. Icons were huge. It made it hard to do anything. I could not get out of it...I finally had to turn the device off and on again to get the display back to normal. Again, I just checked those accessibility features and they are all off. What to make of this?
