Having had problems in the past with battery draining too fast, I was advised to return it to factory settings. On doing this, it worked for a while.
Now the same problem has started occurring again. So, I thought, I would simply reset again.
However, I think, I may have pressed the volume down instead of volume up (or vice versa) as now I have a pic of the android and a message warning me not to turn off the tablet for the last 15 minutes.
Have I done something wrong?
