Android’s Eye Comfort Shield can make your phone screen easier on the eyes by adjusting the light to suit the time of day. The cool blue light emitted by phone screens can make it harder for you to sleep and night and tire out the eyes. Here’s how to adjust it. The process will vary slightly based on your particular phone model. Here’s what it looks like on a Galaxy S21.
Start by opening Setting, scroll down and tap on Display.
Tap on Eye comfort shield.
Choose Adaptive and the phone will automatically adjust the color temperature by the time of day. Or you can customize how it works.
Move the slider bar to adjust the color temperature.
Tap Set schedule to adjust the time. Choose between Always on or Custom.
Tap Custom to change the times.
