The twofold opening camera (which allows the phone to better control how much light it gets) is to a great degree the element of the S9's movements, nonetheless we've been contemplating the measure of a refinement it'll truly make. As per usual, Samsung keeps the hole at f/2.4 — more diminutive and slower than other lead phones — yet the S9 can open up the camera to f/1.5 to let in fundamentally more light when it needs it, as around night time or in faintly lit diners. We are extremely overcome by-side photos starting just before the seven-minute stamp showing the refinement between what the two holes get.
