Best locking app that works with finger scanner but found an issue! This app had no flaws, until I decided to use the "Youtube Red" app with the video minimized playing in the background and decided to lock my screen. It turned the screen black but the video stayed minimized and playing. NOT locking my phone just making the background black. Even after a couple of minutes. This is not a problem if you don't use the "Unlock" with fingerprint option.

The app gets killed and stops working after a couple of days. I have to keep giving it accessibility permission. Also, the accessibility button doesn't work on Android 12, but I guess the newer the version the more functionality we lose. It would be nice if software kept up with Android. The buttons still exist in Android 12 if the user chooses to do that, so it would be nice if the software accommodated for that.

Hello, Accessibility button is enabled on Android 11 and below only. For Android 12 most phone will use gesture navigation which no longer have a place for accessibility button.

May 6, The developer fixed this. Thank you! Have used this a long time. With this latest update 3 days ago on MotoG5+, however, no longer shows up in notification panel and when I go to Lock Settings in this app, it crashes, will not stay open so I can check or change the settings. Widget still works.
