Sorry for the wait. My name is Michael. I will be helping you with your question today.
My first suggestion is to Hard Reset the unit by doing the following:
1. Power off the tablet2. Press and hold volume up and power button3. Release power button when you see RCA logo4. Release volume up button when tablet reaches system recovery screen5. Use volume down button to scroll to wide data/ factory reset6. use power button to choose7. Scroll down to delete all user data8. Use power button to choose9. Use power button to choose Reboot system now
If that doesn't work for you, please let me know.
