How to Enable Night Mode on the OnePlus 3 and OnePlus 3T

If you have OxygenOS 4.0 or higher on the OnePlus 3 or OnePlus 3T, you can follow these steps below if you want to turn on a Night Mode filter.

When Google debuted Android 7.0 Nougat on their Nexus devices, they showed off a new feature called Night Mode. This is something that has been possible on Android in the past (if you had root access to your device), but it is not being baked into the core OS. The main goal of this light filter is to ease the strain your eyes endure when you’re looking at a bright screen (on a phone, tablet or monitor).

So this is great for those use their OnePlus 3 or OnePlus 3T phones a lot. However, there’s also another benefit to the Night Mode tint feature.

There have been studies done that suggest the blue light emitted from a screen on a phone, monitor, etcetera, can prevent us from falling asleep and getting as much sleep as we should be getting. This is tied to how there’s less blue light from the sun when it sets and this tells our body to stop producing a certain enzyme. So if you use your phone after sunset then it could benefit you to use the OnePlus 3 Night Mode feature as you get closer to bed time.

Thankfully this feature is also baked into OxygenOS 4.0 and higher for both the OnePlus 3 and the OnePlus 3T, and can be enabled by following these steps.

OnePlus 3 Night Mode

1. Launch the Settings application
2. Scroll down and tap on the Display option
3. Tap the Night Mode option to toggle the blue light filter on
4. Adjust the slider so that it is comfortable to your eyes

Explanation

As I mentioned in the video, if you want to learn more about the blue light emitted from our displays and how they affect the body then be sure do a web search on Google to learn more. I don’t want to go into more detail than I already have, but there have been multiple studies done that come to the same conclusion. Night Mode on Android also lets the display look less blinding at night so that is another benefit to using it after sunset.

I do want to say that I understand how distracting it can be when you first turn the mode on. Programs for the PC (and even other apps for Android) will gradually increase the intensity of the blue light filter as it gets later in the night so it isn’t as jarring to use. But once your eyes get used to having Night Mode enabled, you really don’t even notice it. I don’t advise that you keep it on during the day, but it’s nice to have on at night.

After using it for a while and toggling it off for a second will show you how much additional strain your eyes go through when the filter is off. So to start, you just need to launch the Settings application and then scroll down to the Device section. From here, you’ll want to tap on the Display option that you see in the list. The Night Mode option should be toward the top of the list here and it’s just an toggle that you flip on and off depending on if you want the blue light filter activated or not.

Once you toggle the OnePlus 3 Night Mode feature on, you should see a slider appear underneath it. This will look exactly like the image shown above (but maybe with a different color theme) and it gives you the ability to adjust how strong you want the blue light filter to be. Sliding this to the left will filter out less of the blue light while moving the slider to the right will filter out more of the blue light. Try to find a comfortable spot but remember that your eyes get used to it.

So if it seems like too much at first, after reading something or viewing the screen for 30 to 60 minutes you probably won’t even notice it anymore. I also want to point out that this feature even comes with a Quick Settings tile to let you turn it on and off much quicker than following the instructions above. You should see Night Mode tile in the area, but if you don’t then you should see the option when you edit the Quick Settings panel on the OnePlus 3 and OnePlus 3T.
