On a tablet when I shut it down sometimes (instead of going off it reboots); not sure if it's something I've done or installed; have been putting a few things on it as I've only had it a few days. It's Android 2.2. Sometimes it will get to the first screen to select the shutdown option and go into reboot mode before I can press it; sometimes I press that and get to the second shut down screen and it reboots; sometimes it will let me press on the second screen and then it reboots; sometimes it works. I've even seen once where it has rebooted and then shut down (with the little Addriod man appearing briefly) before the screen goes blank. Only things I've installed recently are Opera mini (far better than the one that came pre-installed), FB reader, BeamReader and Aldiko. Are any of these known to cause problems? Is there a way of manually shutting down running systems one by one so that I can isolate the app doing this; assuming that an app is the problem? This fault still happens when I have not selected any app from the home screen after rebooting. Another problem is running Youtube videos; I just get the message... "The application Youtube (process com.google android youtube) has stopped unexpectedly. Please try again." However I can run videos from a file on the USB stick. Thanks in advance, Mike.
