My seven home screens will move without me touching the screen. If I hit the home button and move or tilt the phone the screens will keep moving from one to the other. It does not do it all the time but is very annoying when it does do this. Also If I put it in sleep mode and than wake it, the screen to the left of the home screen appears. This if even if I put it to sleep with the home screen appearing last. Any suggestions? Thanks!!
