Always Visible Clock is a useful utility app for Android devices that offers customizable analog and digital clocks. With this app, you can turn off the screen by clicking on the analog clock. The app also allows you to lock the screen immediately, which can still be unlocked with fingerprint when using Android 9 onwards.

One of the best features of Always Visible Clock is its customizability. You can choose between an analog or digital clock, and you can customize the clock face and colors to match your preferences. The app is easy to use and offers a simple interface.

Please note that if you use the fingerprint sensor, you need to tick "I do use fingerprint sensor" at Step 2. Always Visible Clock uses admin privilege to lock the screen, which means you can't uninstall it in the normal way. You need to remove the permissions and then uninstall the app.

Always Visible Clock requires Device Administrator permission on some devices to turn the screen off and lock it. For other devices, the app requires Accessibility permission to turn the screen off and lock it, as pressing the power button. To use this app with full functionality, you need to grant the asked permission.
