Another awesome little feature on the Galaxy S7 Edge is getting notifications with that curved glass. Simply turn your phone face-down, on the glass, and when an incoming call or text arrives it will glow a color you can set. This only works with the default Samsung messages application, but works great. I have it glow pink when my Fiance sends me a message, blue for my dad, and so on. It lets users know who's calling or texting without ever looking at the phone, and being face-down it won't distract others. A small section of the screen lights up.
It's neat, but nothing more than a novelty. Head into settings > Edge screen > Edge lighting to customize this. You can even enable a quick reply that's preset by simply touching the flash sensor on back. It will instantly send a pre-recorded text to that caller or message.
