Samsung Smart Glow is a new twist on LED notification lights
In addition, Smart Glow can be used when taking selfies with a phone's rear camera. When the Smart Glow light starts circulating the rear camera lens, it will mean that a face has been detected and that the camera will take a picture within seconds.
It isn't clear which phones will be receiving the Smart Glow feature, but the current buzz says that it will appear on the Samsung Galaxy J2 (2016) in India. Having said that, there still is a possibility that Smart Glow will be found lighting up the rear camera on the Samsung Galaxy Note 7.
