I've read a couple of post on this and am trying to figure out if I have a defect unit or it is a software problem. Basically the tablet runs fine until I put it down for awhile and then it will not wake up with a quick push of the power button. I have to hold the power in for about 10 sec and then I will get a reboot and things will work until this cycle repeats. I've looked in the file system and there are a bunch of logs generated showing data when it happens (not sure how to interpret). I've tried shutting off the wireless unless the screen is on, reset to default a couple of times, removed the security lock on the screen and other suggestions. I had a 16G unit for awhile before this unit and did not have this problem. I upgraded to a 32G and I've had this problem shortly after I started using. Should I return the unit while I can? It appears to me to be more like a software problem. Is anyone else seeing the same thing?
