Okay, so I have a RCA Voyager 3 tablet and every time I enter my passcode, the screen goes black, then guess back to lock screen! I've tried rebooting it. It worked, but I don't want to reboot every time. I think it was caused by me dropping it least night. But then I realized that it worked fine last night after droping it. Please help! I even tried swipe unlock function! Help as quick as possible!
