Smartphone screens may connect us with the world, and provide countless hours of enjoyment, but our bodies just weren’t meant to be starting at them 24/7. Especially late at night when we should be getting to sleep, that kind of constant exposure to the artificial, often blue-tinged light they produce can mess with our circadian rhythms. As a result, we’ve seen a new effort to limit that effect through software tweaks that modify screen output: things like Blue Shade in Amazon’s Fire OS, or the new Night Shift feature in iOS 9.3. The granddaddy of all these was the Flux app on iOS, and now it’s making the journey over to Android, with the publication of a preview release.
Flux for Android works much as it did on iOS: the software tracks system time throughout the day, modulating screen color temperature to be cooler during daylight hours, and warmer at night.
Right now, the biggest issue with Flux is that this Android preview requires a rooted phone to function – and that’s straiht away going to limit its appeal. It also sees compatibility issues with older KitKat devices, as well as more modern popular phones like Lollipop-running Samsung Galaxy handsets. Even when things do work, there are a few quirks with this release, and you’ll want to familiarize yourself with the app’s release notes before you start complaining about random screen flashes.
While all that adds up to some pretty rough edges, a good night’s sleep might just be worth some temporary setup headaches.
