Google might bring back Night mode to Nexus devices after all
Understandably, Nexus owners aren't keen on letting Night Light go. Not long after its removal from the final Nougat 7.1 release, a thread titled "Bring back Night Mode" showed up in Google's Issue Tracker. It has been marked as a Future Release issue, meaning it might get addressed by Google in an upcoming Android version.
Meanwhile, Nexus users can explore tweaks, such as the Night Mode Enabler app in the Google Play Store (link) or the simple technique explained in this article. There are third-party apps, like the popular Twilight, that enable similar blue light-reducing functionality, too. However, it would be best if the official Night Light feature by Google made a comeback in a near-future Android release.
