In the pre-release version of the Android Nougat, we were able to see the night mode feature which allowed Nexus handset to work more efficient at night or in low-light situations. Unfortunately for the tinkerers, the night mode was hidden before the final release. However, with a little help from this blog, you can some of the features back.The Night Mode, which is quite similar to Apple’s ‘Night Shift’ mode, tints the screen red to get rid of the blue wavelength light. According to Google, this features was removed because of performance concerns, but from the limited testing, this doesn’t seem to be the case on the Final Nougat Release.There is no guarantee that Google will not get rid of this feature, but it is as likely that we could see it being fully implemented in the final release. Regardless, you can easily activate it on devices running Android Nougat

Avoiding the blues

According to scientific research, the blue light emitted by smartphone and tablet displays have a detrimental effect on the victim’s sleep patterns. This is because the wavelengths generated from the blue light tends to stimulate parts of a human brain that control alertness. This stimulation can convince our brains that it is still daytime. The result of such stimulation is that using your phone or tablet late in the evening can make it hard for you to get enough sleep.The Night Mode feature will address this by removing the blue light on your smartphone’s screen by increasing the reds in an effort to minimize disruptions to unnecessary brain stimulations. However, this is not a guaranteed solution. It is still a good idea to get rid of the blue light issue.In case you desperately need this feature on Android Nougat, follow the steps below.

1)      Download the Night Mode Enabler app

Mike Evans, a Developer was swift to bring an easy way of activation the ‘invisible’ Night Mode feature in Android Nougat. You just need to download a small free application from Play Store to unlock the feature. The best part of the Night Mode Enable application is that it does need root to cancel the blue light feature on Android 7.0 Nougat.

2)      Enable Android System UI Tuner

After launching the application for the very first time, it prompts your to activate the Android System UI Tuner from Quick Setting Menu. You only have to slide down the notification bar and then press the Setting gear icon and hold it till it starts to go round.

3)      Activate the Night Mode

Click on the Night Mode icon to enable warmer colors on the screen for a pleasant night viewing experience.With its default settings, the feature will automatically be enabled at sundown and the blue-canceling effect gets stronger as it gets darker outside.

 How Night Mode looks.

The Night Mode feature makes your screen look slightly orange when it is enabled. This is because it is canceling any blue light emitted from your device’s display.
