Samsung may be putting a concentric twist on the notification LED.
According to material obtained by GalaxyClub.nl, we may see a “luminous ring” surrounding the rear camera to replace the single diode. You can assign certain priority alerts, contacts and data or battery usage settings to certain colors the ring will glow. Of course, incoming communications will also get shown off with Smart Glow. It’s an evolution of sorts for the edge effects.
If you plan on using your rear camera for self-portraits for some extra flash or just because, you can fire up the camera app, point the lens toward your face and Smart Glow will glow when it detects your face.
It appears that the Galaxy J2 (2016) intended for India will get supposedly have the feature first. It’s not exactly clear how far or fast the feature will grow, but there’s a good chance it could be on the Galaxy Note 7.
