Check and see if there is a small pinhole on the back. Try inserting a paper clip. This would be a soft reset and has been known to clear up mirror imaging on some tablets. Also a swift hit on the back side of the tablet has been reported to work as well (try at your own risk) lastly try a hard reset but not you will lose you data. This option is found in the settings menu. Hope one of these works for you.

I'm not familiar with that specific tablet, but all Android devices have a way to enter a recovery mode menu that allow you to clear the cache or do a full factory reset. First, try the 'clear cache' option. If that doesn't work, you'll have to do a full factory reset (and you'll lose all of your apps and data).

• Turn off your tablet all the way.
• Then press and hold Volume Up + Power button until you see the Recovery Mode menu.
• From menu on your screen choose option "clear cache" or "delete cache" by using Volume buttons to scroll and Power button to confirm.
• Try to restart your tablet. If it still doesn't work, then do the same thing again, but this time...
• From menu on your screen choose option "wipe data/factory reset" by using Volume buttons to scroll and Power button to confirm.
• After that select option "Yes -- delete all user data", and confirm that.
