Samsung blue light reduction

Please Note: Availability of this hack may be affected by your device model or OS


Scrolling through blogs, playing on apps and replying to emails in bed is a habit shared by a lot of people. For many of us, it’s the only sweet bit of downtime we get all day. But exposure to the blue light emitted by devices, especially before bed, can have a major impact on sleep quality. That’s where the Blue light reduction feature comes in.


This hack is recommended for use during those hours before you want to sleep. Dimming down the blue light (you can even make your device do this automatically at sunset, clever huh?) can alleviate eye strain and reduce the negative impact of gadget exposure before sleep.


  1. With your device unlocked, swipe down from the top of the screen to reveal the Quick Settings panel.
  2. If necessary, drag down the Quick Settings panel to reveal more options.
  3. Tap Blue light filter to immediately activate.
  4. Alternatively, tap and hold the icon to generate the Blue light filter menu. You can also find this by tapping the Settings symbol from the Quick Settings panel, followed by Display.
  5. Use the Blue light filter menu to adjust opacity or schedule activation times such as sunset and sunrise or custom.

I personally use this feature on my S9+. Loving it :winking-face:


One more bit of advice: I tend to get a headache from low quality screens. Having a slightly better (and more expensive) smartphone can really improve the enjoyment of your phone/tv :smiling-face: Even if its only for the headache reduction (I'm quite sensitive to those things, no idea if others also have the same experience). 


Since I realised this I will never buy cheaper screens again :winking-face: Even if its only for my health. 


That's not an hack when it's already a feature 


@GingerSteve, I'm waiting for our marketing folks to try their Jedi mind-trickery to convince me that the light coming on when the fridge door is opened is a "hack". :face-with-rolling-eyes: :face-with-stuck-out-tongue-and-winking-eye:


On topic: I tend to use my laptop more than my smartphone at night - and the blue light filter on that does appear to have helped me sleep better more recently. Certainly, my eyes feel less dried out.

@GingerSteve  Well think "hack " is used loosely, however some  useful features have been highlighted that everyone will not be aware of.   Certainly I  think the Blue filter helps, though  tend to  use laptop or tablet a bit at night.


I use the blue light filter at night but is it best to use it during the day also?
