The camera in LGs new G3 flagship smartphone is pretty special. Not for its 13-megapixel sensor or optical image stabilization — both good things to have — but for being the first among phones to feature a laser autofocus system. The moment you enter the camera app, the G3 starts emitting a cone-shaped laser beam from a window just to the side of the camera. Seeing a synergistic opportunity, LGs mobile team picked them up and made them an integral part of what the company claims is the fastest camera in a smartphone today.
