Samsung Galaxy S7

The Samsung Galaxy S7 was released at Mobile World Congress in February 2016. It features a 5.1" Quad HD Super AMOLED display, with an "always on" function, used to display a clock and notifications. Under the hood, the Galaxy S7 is powered by either a Qualcomm Snapdragon 820 or Exynos 8890 processor, and either the Adreno 530 Mali-T880 MP12 GPU (both dependent on region). It comes with 4GB of RAM and either 32GB or 64GB of internal storage, with up to a further 200GB available with microSD card. The rear shooter has a 12MP sensor, with f/1.7 aperture and phase detection autofocus, and produces 4:3 ratio photos. It also features a dual-pixel system, which allows every pixel to act as a focus pixel, similar to the system used in some DSLR cameras. On the front camera is a 5MP sensor, also with an f/1.7 aperture, and auto HDR. The Galaxy S7 runs on a 3000mAh battery with Quick Charge 2.0 and wireless charging. Other features include a fingerprint scanner, heart rate monitor, Samsung Pay, and Gorilla Glass 4 both front and back. The device is IP68 certified for dust proof and water resistance over 1.5m and 30 minutes.
