f.lux, the popular blue light filtering app, is now available for Android devices.
The program has been available for Windows computers for many years, where it boasts thousands of users.
A few months ago, f.lux was released for Apple’s iOS devices, but it was banned for sideloading (using Xcode developer tools). But ironically, the Cupertino company included a feature called Night Shift in iOS 9.3, which as a native system setting, essentially dims the screen to reduce blue light, aka a job which f.lux specializes in.
Android also has a similar feature available in the Android N preview, and a custom rom version called LiveDisplay has been available in Cyanogenmod since CM 12. Also available are competitive apps such as Twilight (works for non-rooted devices) but which causes a reddish layer to appear on the screen. A much better solution is to use an app which has a root driver, like CF.Lumen.
f.lux also requires a rooted device, running on Android 5.0 Lollipop or above (includes Android 6.0 Marshmallow). IT has various wake up time settings, as well as different light settings for Daytime, Sunset and Night. It even includes a saturation mode for AMOLED displays.
