DigiLux is a free Android app developed by Tunji Dahunsi that enhances one-handed phone usage by providing gestures and brightness control, auto changing wallpapers, auto rotation, accessibility pop-up button, and a trial period. The app uses the fingerprint sensor as dedicated brightness control hardware and allows users to customize the amount of brightness reduction or increase with each swipe. Users can also position the slider closer to the top or bottom of the screen and change its color. The app lets users choose wallpapers for either scenario and set the time for the app to automatically change over. The app supports devices with a FingerPrint Gesture API introduced in Android Oreo such as Google Pixels, Nexus 6P, Nexus 5X, One Plus 5T, The Essential Phone, and Xiaomi Mi A1.
