Screen Locker

This is a small locker app for Android. It allows to hard-lock the phone screen so that even a fingerprint cannot unlock the phone. In this way, an attacker would need to know the PIN/password/pattern itself - copying fingerprints or using the fingers of the owner against his/her will is not possible anymore. Only after unlocking the phone entering the PIN/password/pattern, the fingerprint unlock will work again. Also, this app can be used as an alternative to the "screen lock"-button (e. g. if the original button is broken).

The app uses the Device Admin in order to ask for the force-lock permission. Thus, this app has no access to your data, cannot establish a connection to the internet, or do something else.

This app is open source. You can look at the source code here: https://github.com/tech-AK/screen-locker.
