Can Someone Help Me Please With My Tablet Not Working


Apr 25, 2014
I wonder if anyone can help i bought a Q8H Rapid5 Revo 7" Tablet yesterday and it said to Charge it for at least 7 hours which i have done.
I turned it on today and straight after the lock screen as soon as i try and do anything tablet displays the message, Unfortunately, has stopped with a ok button underneath but if i click ok the message just reappears.
i have tried to click the back button and home button but nothing work so i tried to turn tablet off and i cant do that either as the error message obscures the power off,reboot window i dont know what else to do
