I have had the same entry pin since I first got my tablet - then last nite it sudenly stoped working - I tried all the sugested work arounds such as holding the power & volume buttons to no avail and tried the safe mode (although) I wasnt quite sure I was doing that one rite - so in the end I put it down - when I picked it back up an hour later it worked - after sing for some time I switched it off and went to bed - this moning I have the same problem - I have tried all sorts with no sucess - please help if posible - thank you
