Face Smart Lock Screen Prank is a prank app that lets you scan your friends’ or family members’ faces and then unlock the phone with a special code. It’s very easy to set up and very fun to use.

You can also set different themes, background, and wallpapers.

This is a prank app, so it’s not really a security system. It’s just a joke app, so you can use it for fun and for entertainment purposes.

The Face Smart Lock Screen Prank is also a very good app to protect your phone from unauthorized persons, especially kids. If they try to unlock your phone, it will show a security screen, and they won’t be able to do anything.
