Hi, This morning I started my Galaxy Tab 10.1 and it booted up as usual. It went to the Home screen and placed the tablet down while I went to get my cup of tea. When I came back the tablet would not respond. The screen was black, but I could tell that there was power to the screen, but it was totally unresponsive. I then pressed volume up plus power and held them down for several seconds. Nothing happened. So, I did it again, but for a longer period of time. Still nothing. I then tried holding down the up volume plus the power button, but this time I pushed the volume button up and down about 15 times in rapid secession. It started up and booted to the unlock screen. Everything seem fine now. Is this a know issue? Is it best to return it now while I am still in my 14 day window? Thanks.
