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!!

I will give five stars of course, there is a problem. I have added shortcut to the quick settings (you know when we swipe down) but I see it, it it grays out and does not work, I have to re-add again after starting my phone. (any solution?)

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.
