About this app
Secure quick settings and power off menu, so a thief can not access them
😔 Some device models, like Google Pixel, Nothing phone and others, 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, put the phone in airplane mode or shut it down, rendering any anti-theft protection or device locator app useless.
💡 With this app you can avoid that: you can disable access to the pull down menu (quick settings, control center) from the lock screen and also block the power off menu, requiring the password to power off. If your phone gets stolen you will still be able to locate and track it!
🙏 This app is completely free and has no ads, 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 Personal Safety and Cerberus Kids Safety).
😲 Cerberus Anti-theft gives you other great features to help you recover a lost or stolen device, like providing a fake power off menu (fake shutdown) to fool thieves in thinking they have shut down the phone, while it stays active and traceable.
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 Service to monitor the lock screen and block the power off menu and quick settings. It does not collect or send any information.
