Compared to the 16-megapixel rear camera on the S6, it seems the S7 got a downgrade with a 12-megapixel/4K rear camera .

However, the sensor in the S7 sports Dual Pixel autofocus technology (a.k.a. phase detection) for every pixel.

Additionally, these pixels measure in at 1.4 µm—a full 25% increase from last year's model—which will reduce noise and improve overall image quality.

So, despite having fewer pixels, even photos taken in the worst lighting should come out clearer in a head-to-head comparison.
