Cerberus Lock Screen Protector

Some device manufacturers do not provide an option to protect the quick settings or the shutdown menu with a password, so a thief could swipe down from the lock screen and disable the internet connection or shut down the phone, rendering any anti-theft or device locator app useless.

With this app you can avoid that: if your phone gets stolen you will still be able to locate and track it!

This app is free, yet if you want to have a complete protection for your phone, yourself and your loved ones you can subscribe to the Cerberus suite (Cerberus Anti-theft, Cerberus Persona and Cerberus Kids)

This app uses Device Administration to turn off the screen and lock it when the power off menu or quick settings are being displayed.

This app uses Accessibility services to monitor the lock screen and block the power off menu and quick settings. It does not collect or send any information.
