I want to lend a tablet to a friend of mine and I'm sure he will try to prank me with a locked screen.

What can I do to remove the screen lock, if he returns it with the locked screen feature enabled with a code or something?

    What makes you think he'll stop at locking the screen? Maybe he'll root the phone and install a key logger, also. Jun 5, 2012 at 12:18

    There's a saying in security: physical access is root (admin) access. Anything that you do to try and prohibit him can be easily circumvented if he is really intent on doing something malicious.

    I'm sorry, why are you lending a tablet to someone who you believe is going to mess with it? He may be a friend, but if you feel it's likely that he's going to intentionally do things to your tablet, then don't lend it to him. Jun 6, 2012 at 17:55

One way to prevent this is to create an extra guest profile with help from SwitchMe:

Get root, install SwitchMe, create an guest profile, protect your profile with an password and enable SwitchMe's login manager feature. This allows you to recover the tablet by rebooting into your profile and resetting or deleting the guest profile.

Note that SwitchMe may not work with your ROM.
