Black Screen - Apps on Google Play

I'm using a Samsung Galazy A20 extensively for wi-fi tethering other devices, and keep the phone plugged in all day. The phone has an annoying always-on battery level indicator when it reaches 100%, and I'm concerned about screen burn-in. This app does the trick, keeping the screen black even if you touch the screen. On the A20, I single press the power button, then double tap on the battery level indicator to return to the phone interface.

This is indispensable for android TV boxes and so perfect because it's PURE black. The last app I tried still kept the backlight active. I fired this up and I can't even tell my TV is still on! What's more, my Samsung TV immediately went to cool down mode (those quiet pops as the parts inside cool down/contract). Perfect for bedtime!

I have been using this on my ROG Phone 2, Twindock View mode. When I want one screen to be off, I just run this on one screen. It works fine and would give it a 5*, but one problem for now is that this app prevents my phone to go to sleep when it is running in one of my screens. Edit: 5* now. It was too late for me to realize that the app was designed to not allow the screen to turn off. I reached out to the developer and guess what, he made a version where the phone sleeps! They're awesome.
