Yesterday I was looking in the APP store and clicked on a free APP to see what it was about. Next thing I now my phone is swapping screens like a mad man was sweeping across it at frantic speeds. Calendar, to-do, main screen, installed apps, up, down, right, left.............Well you get the picture. I tried powering down the phone and restarting. After the first swipe to the left, all started again. Powered down again and back on. Same results. Finally powered down, removed battery, let set. Installed battery, powered up and all seems to be ok. Anyone else experienced this? Is it a fluke or something going hay wire?
