Samsung phones are very powerful devices and come with lots of features. Some of them are easy to understand but there are some features that cannot be understood by everyone. In this post, we will talk about the Samsung blue light filter feature that helps in reducing eye strain while using the device. Then we will talk about the blue notification light blinking issue.

Part 1. Samsung Blue Light - Blue Light Filter 

First, let's talk about what is Samsung blue light filter and how do you turn it on or off on your device.

1.1 What Is The Blue Light Filter on Samsung?

Many times, your eyes must be tired when you continuously use your phone. This is the reason why a blue light filter can help you. The blue light feature on your Samsung phone reduces the blue light that is displayed on your screen. This feature is helpful because blue light can affect the production of sleep-inducing hormone-melatonin, thus filtering it will help you get a good sleep.

1.2 How Do I Turn on or off The Blue Light Filter on My Samsung?

Follow these steps to easily turn on or off the blue light on your Samsung device.

Step 1: Go to Settings -> Display.

Step 2: Touch the slider to enable or disable blue light.

Step 3: You can adjust the opacity and select 'turn on as scheduled' to automatically enable it at the set time. You can also enable or disable blue light filter from the quick settings panel.


Part 2. Samsung Blue Light - Blue Light Blinking

The notification light in the phone alerts you when you receive notifications. But many users have complained that blue color light keeps on blinking even though there is no unread notification. See one user's complaint on one of the popular online forums.


I'm using Samsung Galaxy S9. Normally, when I receive notifications on my phone, notification light blinks once. It stops once I turn on the screen and check the notifications. But recently I noticed that the blue light is blinking continuously even after I checked all the notifications. Is it a major issue? I need a solution for it.
