Black screen allows you to play video when the screen is off. Turn off the screen at any time and save battery. Black screen can be used to watch music videos, listen to podcasts, record videos, take selfies, etc when your screen is off.
This saves battery life in AMOLED and OLED devices because the screen turns off completely when showing black.
Use the floating button to quickly turn off the screen and unlock it by tapping it.
App feature list:
• Floating button to quickly lock the screen
• Save battery on AMOLED and OLED screens

Warning: This is not a lock screen app, it’s just a black screen overlay on top of the app you’re using. This saves battery life on AMOLED devices.
