Phone: Samsung J5:
I inadvertently invoked the Screen Unlock option in the Wondershare Dr. Fone app. I want to go back to the previous state with the normal lock screen. The screen doesn't appear any more which is what the app does. How do I undo the 'Remove phone lock screen' change. It appears to have written to my sim because if I remove the sim the lock screen option behaves as normal.
I assume there must be a file written which I have to identify and erase. Can anybody help me? I really want to reverse this situation. Any advice deeply appreciated. Thanks in advance
@uservZOEOqWUjl have you tried removing that app entirely?
If that doesn't help:
