It’s no news that the Galaxy Note 8 ships with a front-facing LED indicator that shows a signal when you receive a notification or when your battery is running low. Although this feature is much needed during the day, you barely need it at night, which is why Samsung has integrated a setting that allows you to automatically turn it off at night.
To activate this, head over to the settings:
Select Sounds and Vibration
Choose Do Not Disturb:
And then select Hide Visual Notification
You can now slide the toggle next to “Hide When Screen is off” to On.
With this enabled, you can disable the LED when you are headed to bed, and automatically switch it back on in the morning.
