Screen Color Temperature App f.lux Hits The Play Store

March 15, 2016 - Written By Dominik Bosnjak

The f.lux app has been forcing the screens of our devices to go easy on our eyes with color temperature for a few years, including versions for Windows, OS X, Linux, and even an iOS version for jailbroken iPhones and iPads. Now, as of yesterday, it’s finally available on Android smartphones and tablets. This official preview version hit Google Play Store less than a month after the Android port of the app went into the beta testing phase of development.

Just like the previous iterations of f.lux, the Android version is designed to adjust a display’s color temperature based on your location and time of day. Why would it do such a thing? Well, primarily to reduce eye strain during night-time usage and avoid disruption of sleep patterns as best as possible. That basically means that as the day progresses, the screen temperature of your device will get warmer up until a certain point before dusk, when the opposite will be true.

Unfortunately, the catch is that f.lux currently only works on rooted Android devices, and it’s even further limited by the OS version. As the app’s developers explain, f.lux won’t work on some rooted devices running Android 4.4 KitKat, and while most 5.0 Lollipop and 6.0 Marshmallow phones will be able to utilize it, a lot of Samsung Galaxy models running any version of Lollipop may encounter some issues or not work at all. The preview version of f.lux will also make your screen flash each time it gets updated through Google Play, and DRM apps like Netflix will completely turn it off from time to time. The app, not the screen. The fix is in the works for that issue, though, and the JustGetFlux team is also apparently working on a way to have its app do its magic on unrooted devices as well. In case you don’t have a rooted Android device or f.lux doesn’t work on your phone, there are definitely some similar alternatives on the Google Play Store. One such app is Twilight which doesn’t remove blue sub-pixels of your display one by one, but it does apply a red filter over the entire screen which still makes using your electronic companion during night-time a bit more bearable on the eyes.
