S10 Notification Light: Turn It On or Off

Card No. 06·6653 · Updated · Standard formula, shown below

Yes, you can turn on the notification light on a Samsung Galaxy S10, but it is not a simple toggle. The S10 does not have a dedicated LED notification light; instead, it uses a feature called the “Edge lighting� that lights up the edge of the screen for incoming notifications. This guide explains how to enable and customize that feature, and what to do if it is not working.

Background: The S10 and the Missing LED

The Samsung Galaxy S10 series (S10, S10+, S10e, and S10 5G) was released in 2019. Unlike many earlier Galaxy phones, the S10 does not have a physical notification LED. The hardware simply isn’t there. Instead, Samsung implemented a software-based alternative: Edge lighting, which uses the curved edges of the display to show a colored glow when a notification arrives. This is similar to the old LED, but it only appears for a few seconds when the screen is off. If you are coming from an older phone with a blinking LED, you may need to adjust your expectations.

How Edge Lighting Works

Edge lighting is a visual effect that activates when the screen is off and a notification comes in. It draws a colored line around the edge of the screen, matching the color of the app icon or a color you choose. The effect lasts for a few seconds, then fades. It does not blink continuously. To see it again, you would need to wake the screen or receive another notification. This is a key difference from a traditional LED, which blinks until you check the phone.

Turning On Edge Lighting

Here are the steps to enable Edge lighting on your S10:

  1. Open the Settings app.
  2. Tap Display.
  3. Tap Edge screen.
  4. Tap Edge lighting.
  5. Toggle the switch to On.

Once on, you can customize the style, color, and transparency. You can also choose which apps trigger the effect. By default, it may be set to only show for a few apps, so check the “Manage notifications� section to make sure the apps you care about are included.

Customizing Edge Lighting

After enabling, you can tweak the look and behavior:

  • Style: Choose from Basic, Glow, or Multi-color effects.
  • Color: Pick a single color or let it match the app icon.
  • Transparency: Adjust how opaque the effect is.
  • Width: Make the line thicker or thinner.
  • Duration: Set how long the effect stays on (1–5 seconds).
  • Show while screen on: If you want the edge to light even when the screen is on, enable this option.

These settings are found in the same Edge lighting menu.

Common Problems and Fixes

If Edge lighting isn’t showing up, try these solutions:

  • Check that the screen is off: Edge lighting only appears when the screen is off. If you are testing with the screen on, it won’t show unless you enabled “Show while screen on.â€�
  • Check notification settings: Go to Settings > Notifications and make sure the app has notifications enabled, and that “Edge lightingâ€� is allowed for that app.
  • Battery saver: Battery saver mode can disable Edge lighting. Turn it off or allow Edge lighting in the battery optimization settings.
  • Do Not Disturb: If DND is on, notifications are silenced, and Edge lighting may not appear. Check your DND schedule.
  • Restart the phone: A simple restart often fixes temporary glitches.

Alternatives: Apps for a Real LED

If you really miss a blinking LED, you can install a third-party app that simulates one. Apps like “Notify Buddy� or “LED Blinker� use the screen to show a colored dot or a blinking light. However, these apps use battery and may not work perfectly on all S10 models. They also require accessibility permissions to read notifications. Keep in mind that they are not official Samsung features, so they may not be as reliable.

Frequently Asked Questions

Q: Does the S10 have a notification LED?
A: No, the S10 does not have a physical LED. It uses Edge lighting, which is a software effect on the screen edges.

Q: Why is my Edge lighting not working?
A: Check that the screen is off, the app is allowed to send notifications, and that battery saver or Do Not Disturb is not blocking it. Also, ensure Edge lighting is toggled on in Settings.

Q: Can I make the notification light blink continuously?
A: Not with the built-in feature. Edge lighting only shows for a few seconds. Third-party apps might offer blinking, but they are not official.

Q: Does Edge lighting use a lot of battery?
A: It uses minimal battery because it only activates briefly. However, if you have many notifications, it could add up. You can reduce the duration or turn it off to save battery.

Q: Can I set different colors for different apps?
A: Yes, you can set Edge lighting to use the app’s icon color, or you can manually assign a specific color to each app in the Edge lighting settings.

Q: Will Edge lighting work with the screen on?
A: Only if you enable the “Show while screen on� option in the Edge lighting settings. By default, it only shows when the screen is off.
