Auto Shine is a free, open-source Android application that automatically adjusts screen brightness according to surrounding light conditions. It provides an alternative to Android's built-in adaptive brightness system with greater control over brightness behavior. Users configure four pairs of ambient light sensor readings and preferred screen brightness levels. The application calculates intermediate values through linear interpolation to create a personalized brightness response. Its primary operating mode adjusts brightness when the screen is unlocked or the device rotates. This approach avoids continuous brightness fluctuations that can become distracting during use. A background service maintains the required monitoring functionality, with permissions for system settings and battery optimization exemptions. Auto Shine is designed for users who prefer predictable brightness adjustments.
