Alot of these tablets ship after they have been setting a while and the software gets a little out dated before it is sold. Sometime updating the software to the latest version can help. If that dosen't do the trick you may have to reset it back to factory settings.

Power off device, select volume up and then power, hold power for 5-7 seconds and let go without releasing volume up. When u get the android menu scroll down to wipe data navigating with the volume buttons and then to wipe data.
