How to activate Night Mode on Android

Popularized by iOS 9.3, the Night Mode function is now available on many Android smartphones. This function allows you to apply a filter to the screen to minimize eye strain and reduce the blue light emitted by your smartphone screen. In this article, we’ll tell you how you can activate this function, regardless of whether or not it is a default function.

More and more users are having problems with eye strain due to the amount of time they spend in front of screens. It’s not that surprising when you consider our modern lifestyles (TV, computer, smartphone, tablet…). The eye protection mode, as Huawei calls it, is an effective way to reduce blue light. Blue light has a negative impact on sleep as it disturbs the production of melatonin, an essential sleep hormone.

A default feature on some smartphones

By default on certain smartphones running under Nougat

Recognizing the importance of this mode, Google decided to integrate it into their Pixel running on Android Nougat. To activate it, just go to Settings > Display > Night Light. You can also configure it so that Night Light will turn off automatically at certain times.

By default on some other models

A number of manufacturers aren’t waiting around for the next Nougat update to introduce a Night Mode on some of their phones. This is the case for Honor, Huawei, Asus, OnePlus, Samsung…Ggenerally, all you need to do is just go to Settings or the shortcuts to activate it.

Get the night mode feature with an application on the Play Store

At the moment there are a number of apps available on Google Play that allow you to achieve the same result. One of the most popular ones around at the moment is Bluelight Filter. It has the same functionalities as those you find on Android, with more new options such as selecting the filter color from seven available shades, shortcuts on the home screen, a notification widget on the screen and an activation time schedule.

  • A so-called bluelight filter is supposed to reduce strain on your eyes if you are in the habit of using your mobile phone for long hours, especially if you use it to read extensively. However, the medical justification for this kind of thing is still controversial. Some people solve this issue by using an ebook reader like a Kindle for reading. In my experience, installing and using an app for bluelight filtering is not an option. All the apps available are too crude or have intrusive adds or are not well-integrated into the system. Only the Nougat filter is worth using. Even the much-touted Twilight is worthless. Such things need integration into the operating system, not an app. That should perhaps teach us that basic smartphone functions need integration into the ecosystem, not imposed by an app.

    I use it on my phone and find it helps at night when my eyes are tired. Bottom line is it's supposed to help if you plan on going to bed because the blue light is supposed to make it so that it's more difficult to fall asleep.

  • Nearly all my long form screen time is on ereader apps like Kindle, Moon+, and the Zinio magazine app - except for Zinio I can choose a background/foreground format that's comfortable and don't want Android or some other app to fool with it. Not sure how this affects video. Not a killer for me. Sometimes looks like a lot of development is "because we can" rather than some urgent need.
