Samsung Galaxy S7

Hardware

The Galaxy S7's hardware design is largely identical to that of the S6; it retains its metal and glass chassis, but with refinements such as a squarer home button, and a thinner protrusion for the camera. Both models will be available in black and gold colors; a white and silver version will be available depending on the market.The S7 and S7 Edge are IP68-certified for dust and water resistance; unlike the Galaxy S5, the S7's ports are sealed and therefore it does not have protective flaps. Moisture in the charging port prevents the phone from charging.^[

Galaxy S7 devices are equipped with a Samsung Exynos 8890 system-on-chip and 4 GB of RAM. In the United States and China, the S7 uses the quad-core Qualcomm Snapdragon 820, as unlike Exynos, it supports the CDMA2000 networks which are still extensively used by some U.S. and China carriers.The heat from the processor is transferred with a 0.4mm thick water-to-steamheat pipe cooling system. The S7 includes either 32 or 64 GB of internal storage (in most markets only the 32 GB model will be available). The micro SD card slot was restored, enabling expansion of storage capacity. As well as accepting a multitude of micro SD cards, to top it off ,with the unveiling of the Sandisk 200 GB micro SDXC the Samsung Galaxy S7 has a significant data storage capaility

Both the S7 and S7 Edge feature a 1440p Super AMOLED display; the S7 has a 5.1-inch panel, while the S7 Edge (succeeding the S6 Edge+, as there is no longer a 5.1-inch curved-screen in the S7 lineup unlike the S6 Edge) now uses a larger 5.5-inch panel. As with the prior model, the S7 Edge's screen is curved along the side bezels of the device. Both models also have larger batteries in comparison to the S6, with 3000 mAh and 3600 mAh capacity respectively and support for wireless charging. They also feature a 12-megapixel rear-facing camera with a "Dual Pixel" image sensor and f/1.7 aperture lens.

Some carriers like T-Mobile provide the device with a locked bootloader, preventing rooting the device or installing third party system software.

Software

The Galaxy S7 ships with Android 6.0 "Marshmallow" and Samsung's proprietary TouchWizsoftware suite. The new TouchWiz also allows the user to disable the app drawer. A new "Always On" functionality displays a clock and notifications on-screen when the device is in standby; the display is turned off completely if the device's proximity sensor detects that it is in an enclosed space such as a pocket. Samsung claims this feature would only consume half a percentage of battery capacity per-hour. New widget panes can be displayed on the edge of the S7 Edge, in "Edge Single" and wider "Edge Single Plus" sizes. Android Marshmallow's "adopted storage" feature was disabled by Samsung and is not usable.

The Samsung Galaxy S7 received support for the Vulkan 1.0 low-level rendering API.
