How to Enable the Hidden ‘Night Mode’ Setting on Android 7

Our phones have become our constant companions, wherever we go, whatever we do. We spend a considerable time of our day looking into our phones, so much so, that we always manage to take a small peek into our screens even in the middle of the night. But, did you know that using phone at night is not good for our health. This is because, the blue light emitted from the phone makes it stressful to look at the screen. Looking at the blue lit screen for prolonged time post sunset puts a unhealthy strain on the eyes.
To cater this problem, Google has come up with a solution in Nougat. The feature is called “Night Mode”, it scrubs off any blue light reflected from the device screen to ease out the strain on the eyes. This feature is same to flux for desktop computers and that to Apple’s Night Shift for iPhones. It turns on automatically if scheduled. You can even do it manually from the Quick Settings > enable Night Mode.

The feature is hidden in Android Nougat therefore, to activate the dormant setting you have to use an app. There is no need to root the device as the app is enough.
Note:  The app will work only on Android 7.0 Nougat.
