Essentially, the blue light coming out of the screen can cause eye strain, especially at night. Not to mention that studies have shown that it stimulates the brain. As a result, it is more difficult to fall asleep at night. That's where Samsung's Night Mode comes in.

Since the Galaxy S8 is running the latest Android 7.0 Nougat out of the box, it is immediately available to owners. It is customizable, can light up with a schedule and is very useful. Without further ado, here's how to use it.

Night modes have been around for a long time on some devices. Recently Apple added it to iOS for the iPhone, and in 2016 Samsung did the same with the Galaxy Note 7. If you haven't tried it yet, it's one of the many features we highly recommend.

Basically, owners can set a schedule for the blue light filter, and you're set. It will automatically turn on and off everyday for you. Let's start.

How to Use Galaxy S8 Blue Light Filter

By now, most Galaxy S8 users have probably gone through the settings menu to familiarize themselves with the device. If not, we recommend changing these 10 settings first. Next, customize and configure your night mode schedule.

Instructions

As soon as the filter switch is activated, users will instantly notice a huge difference. Blue light is completely removed from the Infinity Display and you will see an amber or reddish tint on the screen. Adjusting the slider will add more or less filter, for specific user needs or preferences.

All blue lights will be filtered out until this is turned off. There is also an easy-access quick setting for the filter in the notification drop-down bar.

Set a Blue Light Filtering Schedule

The best route is to set a schedule. This way, everything will happen automatically. At night, it will light up and reduce eye strain. Then in the morning, back to normal. Set it to your sleeping habits and forget about it. Here's how.

Instructions

That's all we can say about it. Now every night it will automatically filter the whole blue night. Helps relieve eye fatigue and makes it easier to fall asleep at night. Well, according to studies. Whether or not owners use this feature is up to them. Personally, I've enjoyed it ever since the Galaxy S7 Edge received Nougat, and continue to use it to this day.

It's also possible that it might help improve battery life slightly. As the device does not display as many colors or become as bright. Although the impact will be small. While you're here, learn how to customize the on-screen buttons at the bottom of your device or enable all apps to use full screen. For more details and how-to's for the Galaxy S8, visit our device portal.
