How to lock using fingerprint

Friction

I just received my Umi Super and have setup the fingerprint sensor, but I cannot find a way to Lock the phone with my fingerprint only to Unlock it. Can someone explain to me how it's done?

also interested but i dont think it can be done, doesn't it require a more "advanced" sensor to do that?

I watched quite a few review videos on YouTube before purchasing this phone and it looked like they were using the fingerprint scanner to lock the device every time they were checking the fingerprint scanners ability.

There is an application named "Fingerprint to sleep" on the play store.
