Better icons. Dynamically using "Camera 2" API for newer phones (Lollipop, Marshmallow and newer).
Use screen as a light source. Swipe to decrease and increase brightness.
Also menus, to : switch on flash and other functions. App works by not letting screen sleep (lock up). If you need it to lock, can use menu/ Screen Dim or exit the app (back button or home button).
Ads are shown on the about screen only. That is what pays for development and maintenance.
Works on Android 16 and up
