Low Brightness for Android

Low Brightness for Android lets you dim your screen below Android’s system minimum, making nighttime phone use more comfortable in dark rooms or outdoors. Adjust overlay opacity and color, use the Quick Settings tile for instant control, or schedule automatic dimming.

The app includes a built-in lux meter for measuring ambient light and features a lightweight, battery-friendly Material You interface. It works without root access or an internet connection and uses minimal permissions. An AccessibilityService keeps the dimming overlay visible across apps, games, and browsers without logging or sharing personal data.
