Fulscrn lets you use every pixel on the screen to provide better experience for reading books, watching videos and playing games. However, Fulscrn isn't a perfect solution. Due to System's limitation, when fullscreen mode on, Back and Keyboard are disabled. Sorry for the inconvenience. Enjoy :-) FEATURES - Force all apps to Immersive Full-Screen Mode (Hide Status Bar & Navigation Bar) - Notification Control Bar - Material Design MORE PRO FEATURES - No Ads, No Tracking - Shortcuts - Tile - Third party apps integration (Tasker etc.) NOTE Network Permissions only used by Ads.
