The best locking screen!! Works perfectly with my Mi A2 just the way I wanted, which I couldn't find in other apps. I don't understand the complain of others. This app is small, works with the fingerprint scanner, and it can also create a locking button under the notification!! Most importantly it's not just making the screen to black, but it really does lock the screen!! Five stars!!

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.

Nice app, although it needs 5 seconds to really lock the phone that doesn't matter. Sometimes you click to lock and suddenly forget you wanted to do something ekse, so it gives you time to change your mind. Nobody will pick up your phone within 5 seconds. After those 5 seconds it will lock and the phone needs to be unlocked with the fingerprint or pincode. Works well. Nice app. So far the best I found.
