I have a Samsung Galaxy Tab 2. My daughter put a screen lock on and doesn't remember the code. How do I unlock it?
If you log on to android device manager, you can send a lock request, allowing you to change the password. Just be sure to change it after!
As a alternative, keep getting it wrong until "forgot password?" and login in via google. It will then let you reset the password
First off the tab. Then 1. Power key 2. Volume up key 3. Main key
Press same time. After come option then select wip aLL data . Your tab will reset. Rember. After reset you lose all data . Which have in your tab memory.
