After navigating a treacherous opening, we find our way into the back of the phone.

We head straight to the rear camera to get a look at the fancy new dual aperture camera in action.

The camera auto-adjusts the aperture to adjust for low light (at f/1.5 it's got the widest aperture of any phone) while maintaining a more standard (and sharper) f/2.4 for normal photos.

Standard camera lenses use at least five aperture blades to keep the aperture roughly circular throughout many f-stop adjustments. This Galaxy's aperture has just two rotating, ring-like blades for its single adjustment.
