On the back, there's a 16-megapixel camera with optical image stabilization, though the bigger changes have arguably made on the front. Samsung has equipped the Note 4 with a 3.7-megapixel front-facing camera and an f/1.9 aperture lens, for 60-percent more light sensitivity than the typical f/2.4 lens, and the heart rate sensor beneath the main camera can act as a shutter release for selfies.

Meanwhile, though the front lens captures 90-degrees by default, it can snap a 120-degree picture.
