Samsung seems to have been inspired by Android 7.0 Nougat, which will introduce a blue light filter to stock Android; this means there’s one less feature we will have to look forward to whenever the company brings the upcoming version of Android to the Note 7 and existing devices. Samsung has also added a toggle for the filter in the quick settings panel for easy access. Basically, this means you won’t have to download a third-party blue light filter app if you buy the Note 7, although the phone’s built-in setting won’t be as customizable as those third-party apps.
Blue light isn’t completely bad, and everyone has to get enough of it in addition to the reds and the greens to have their eyes functional properly. But overexposure can cause eye strain and make it hard for you fall asleep at night, and an out-of-the-box option to reduce blue light is just another minor yet important feature that Samsung has added to its latest flagship smartphone.
