I have a whte android tablet thats about 7" wide. It has no name or model on it, but it does say WM8650 on the user manual. I had this tablet out of the box just long enough to charge the battery, set the wi-fi, and change the time zone. I was looking at the other settings and noticed a clalibration screen. I looked at it but ignored it and went back to the settings window. All of a sudden, I found the screen icons don't work anymore. I cant get this thing to do anything. I reset it using the little pin hole in the side, but it didn't go back to the original settings. It still my time zone in it. I can scroll the the icons on the right side of the screen, but none of the icons anywhere work. So, 10 minutes ot of the box and this thing is useless. Any ideas how to reset it and make it start working again?
