How to Turn On the Galaxy S8’s Blue Light Filter


Your mobile phone may be keeping you up at night. Smartphone screens give off blue light, which can disrupt sleep patterns by making your body think it’s daytime.

The Galaxy S8 has a built-in feature for filtering out that light; you can even set things up so that the phone’s color tones shift as bedtime approaches. Here’s how to use the S8’s Blue Light filter feature.—Don Reisinger

1. Select Settings.

2. Choose Display.

3. Toggle on the Blue Light Filter option. You’ll immediately see the screen change from its regular brightness to a yellow-ish color that will be much easier on your eyes.

4. Tap on Blue Light Filter to go to the feature’s settings where you can customize things.

5. Choose the opacity and decide whether you want to keep the blue light filter on. If you’d rather schedule when the filter kicks in, select Turn On As Scheduled which lets you apply the filter after sunset or on a customized schedule.

6. When you’re all set, just hit the back button, and the filter will adhere to whatever schedule you’ve set.

    Hi Tom, thanks for the useful info(: so my question is:
    Can I record music on Snapchat with my earphones on?
    I could do it with my s7 but having trouble with the s8. I so hope this is possible.

    Face recognition is trash on the s8 never worked with or without glasses. Would set the face recognition and then turn my phone off wluldnt move at all and NOPE! ...and the fingerprint sensor is confusing with the camera on the back. LOL oh well atleast its the newest samsung out, so i got that going for me lol

  • Trigga13
    Umm should the apps that I have put into the secure folder still be accessible when I bring up the apps screen??
  • Alex_480
    When I transfered my app to secure folder I could not launch it. Why?

    This article doesn't work for me. Privacy and Emergency doesn't appear in my settings.
  • sciancaleporejoe
    I was searching google for that same question ,Trigga13 ,when I found this article (which DOESN'T EVEN answer the question) lol anyway, it makes no sense to lock something in a secure fodder if it can still be accessed from the app drawer

    Seriously thanks Tom for your tips ? Turn off NFC. Turn on flight mode, reduce GPS accuracy, lower your screen resolution? Why not just turn the damn thing off. Battery will last a long time then. These kinds of articles are pointless. You've spent a shed load of money on your phone. It has wireless charging that allows you to conveniently charge it. It has fast charging. Here's an idea. Enjoy your phone and charge it in a few minutes when it's running down. Finger print sensor works fine for me. As does Iris/face recognition.

    Hi, I am a new Galaxy S8 owner. I am having trouble connecting my phone to my cat via Bluetooth. I found another chat page and it seems many users are having the same issue? Can you provide an advise to solve this problem? Thanks, Amy new user

    I hate this phone. I hate Bixby and now my text is messed up.

    It has been a while since I have updated my mobile phone and was awk'd with all the new features (display, security, applications, communication, etc) on the Galaxy S8+.
    In the past, it was always a chore to switch to a new phone due to all the re-configuration and re-installation steps. There are now tools that come on the phone that helps you get all your old applications reinstalled and configured. Makes getting a new phone a 'good' experience. Happy with my new Samsung...

    Accuracy of the S8 fingerprint sensor is very poor; to vastly improve recognition, add and scan the SAME finger 4 times ;)
  • krisstie228

    Sure let me just disable and downscale all the features of my expensive flagship phone sandbagging it when I could have just bought a cheaper phone in the first place.
