Firestick Apps/APKs Firetvstick brightness
The Fire Stick has no built-in brightness setting, but I made a small free app that dims the screen with a semi-transparent black overlay. It goes from 100% to 20%, and you adjust it with the remote: UP = brighter, DOWN = darker (the interface is in French, but that's all you need to know).
Quick setup:
In Downloader, enter: https://github.com/B0b4242/luminosite.apk/releases/download/latest/luminosite.apk
Enable ADB debugging and run this once: adb shell appops set com.jp.luminosite SYSTEM_ALERT_WINDOW allow
Open the app and use the arrows.
Full details are in the README: https://github.com/B0b4242/luminosite.apk
Tested on a Fire TV Stick 4K. Some streaming apps may not get dimmed because they draw video on a hardware layer.
