COMMON PROBLEM

What should I do if the purchased lcd tablet cannot be removed?

Q

A

You should first check if the screen lock button is turned on. If you have already locked the screen, cancel the lock screen and press the clear button. If it still can't be removed, it is recommended to replace the battery. If the problem has not been solved, please contact our after-sales service department, call the above service or call us.
