Ratings and reviews

Doesn't work. I have a brand new Galaxy A50. I launch the app, it asks for a fingerprint, I do that, and it cycles the screen back on, unlocked. It never turns the screen off. Yes I have enabled the "change system settings" permission.. Uninstalled. I found an app that actually works & turns the screen off and locks it. And one should not have to be a beta tester to get an app that works. If the app isn't ready for release don't release it until its tested (its what I used to do).

I've tried a LOT of the screen-off apps (possibly most of them) including many of the paid apps, and this one is by far my favorite! My LG phone had this feature built in, called "knock off" - until I switched to a third-party launcher app. I really missed being able to turn my screen off without using the power button and without locking it. So I was thrilled when I finally found this app. All of the other apps I tried automatically locked the screen, disabled the fingerprint sensor so I had to use my PIN to unlock the phone, or kept the faux black screen for a very long time before the screen timed out (during which time, accidentally hitting the volume button, etc would turn the screen back on). This app temporarily lowers the screen time-out so the faux black screen only lasts a brief time before the screen times out. Once the screen times out, I can use LG's built-in "knock on" feature to turn the screen back on later without having to unlock it. (For some reason, knock on still works, even though knock off doesn't.) The launcher app I use (Nova Launcher) allow me to set actions for various gestures (like double-tapping the screen), so I was able to configure the double-tap gesture to activate this app. Now, double-tapping on my home screen turns it off just like it did originally!

Really optimized app with 0% RAM use. It is only uses 5-6 MBs of the internal memory. The screen will be off as soon when we touch the Sscreen off icon. BUT.... actually the screen is not got locked after tapping the icon, the screen will be go to standby mode and it is almost same as the screen on. And it drain battery more quickly since the screen is always on 😭😭
