About this app

Backlight! is a free brightness app/widget for Android that changes your devices’ screen backlight with a single click. It also allows complete custom brightness levels. You can even assign it to a gesture or a main dock for easier access.

1. Doesnt work on Sense UI devices (i.e. Hero).
2. Potential conflict with Juice Defender. JD seems to negate any requests of this app to change brightness.

Android recognizes values from 1-255 with 1 being darkest and 255 being brightest. It also has support for automatic brightness. Default levels are 1, 50, 150, and 255 respectively. To enable Auto Brightness you can use the letter 'a'.

Backlight! controls the screen brightness level only. It does not adjust keyboard brightness or other light features of the phone.

Don’t forget to add/re-add the widgets to the home screen!

It used to have a separate app to enter the settings. Now, you see settings (with the current ones) when the app first starts up. It's hit-and-miss to get settings that work for your phone. I've used this app on 5 phones and each display needed tweaking, by changing existing settings or adding more. To get to the settings form again, now you have to uninstall and reinstall. Once set up, though, it's easy to use. Just tap the icon to cycle through. I like it so much I've kept it for years.

Works well on Samsung J6 (2018) & Tab A 10" both Android 10. Bottom 'Home' bar flashes white on brightness level change momentarily. 100% does not show up correctly within the icon, however 99% being 1 character less shows OK. Preferences 253 instead of 255.....Remember this is a 'Widget' & installs differently to an 'app' or it would appear not to be working.. .. Dec 2020
