The Samsung Galaxy S10 has a clever alternative to intrusive notifications that crowd the top of your screen and interrupt whatever you’re doing on your phone.

When you’d ordinarily get a notification, the curved edges of the Galaxy S10’s screen can light up, letting you know that a notification has arrived. This is known as “Edge lighting.”

Samsung gives you a few ways to customize this Edge lighting: For example, you can choose when it happens, which apps can use it, and what kind of lighting effects you’ll see.

The Edge lighting style page is all black, with a few controls at the bottom to configure the lighting effects.

Here is what they do, though you can figure it out pretty easily just by experimenting with the options:

  • The Effect button gives you a half-dozen options for how the light appears, including a "wave" effect, a soft glow, a multicolor swirl, and others. Tap each one to see the effect. The last one you choose is the style that take effect when you save your changes.
  • Color lets you choose the color of the effect. There are a number of preset colors, or if you choose "Custom color," you can set a unique color for each app, so you know what kind of notification you're receiving by color alone.
  • Transparency affects the intensity of the effect, including how bright it is.
  • Width determines, as the name suggests, the thickness of the lighting effect.
  • Duration lets you control how long each notification lasts.

When you're done making changes, tap "Done" to save your lighting effects.
