Sunday I left my Memopad 7 in the car for about 8 hours. On the floor, with the cover on it. It was working fine before this, and the touch-screen has been hit or miss since then. To unlock it, I have to do my pattern slowly and deliberately... sometimes taking two or three times to unlock it. Once in, I cant get the pull-down menu to work at all, and some parts of the screen seem unresponsive and dead. A buddy of mine said i cooked it. it might have gotten about 90 degrees in the car, but cant imagine it getting that much warmer. It works the same way, plugged in or not. Ive tried rebooting it, both with the micro-SD card in and out... nothing seems to matter, it acts the same. I looked at the screen and cont see any physical damage. Any suggestions?
