I was uninstalling applications to see if one of them was affecting the screen: things like live wallpapers, calendar apps and a battery monitor. I would stop the app first then uninstalled it. Then I would restart the tablet. For some reason, the device gets to the animation ( the four colored dots) and it stays there. I have to hold down the power button to get the device to power off. I've tried to restart it a few times, and it does the same thing every time. I can get to the reset/boot mode screen by pressing the power & Vol.Dn to get to recover mode, but I thought I'd ask here in case someone can offer anything to try first. This is depressing, because I thought this tablet would work great. I just didn't get to backup stuff that's not already on my desktop PC. At lest I backed up the installed applications yesterday.
