Material Flashlight2.8

Turn an Android device into a handy light source by switching its camera LED or another supported light module on and off with Material Flashlight. It can also use the screen for illumination when the camera light is not the chosen source. Continuous lighting is complemented by a strobe mode with an adjustable interval, while SOS mode produces a recognizable signaling pattern.

A music strobe mode listens to nearby sound through the device and changes its flashing response to match the surrounding audio. Widgets provide quick access to the controls, and Android 7 or later can place a Material Flashlight toggle in Quick Settings. Operating the camera LED requires camera and flashlight permission, while music strobe uses audio recording permission to analyze surrounding noise. The screen module uses write system settings permission to set its maximum brightness.

The app fits everyday tasks such as finding objects in the dark, signaling for attention, or adding sound-responsive light to music. Material Flashlight is open-source Android software in the System Tools category, and its current version is 2.8. It requires Android 4.1 or newer and supports Universal architecture.
