The S7 comes with a 5.1-inch quad HD Super AMOLED display with a resolution of 2,560 x 1,440 pixels (that's a pixel density of 576 pixels-per-inch for all you pixel-peeping junkies out there. It's powered by a Snapdragon 820 processor (the Samsung Exynos chipset is used in some regions), and has an upgraded 4GB of RAM. The storage options are 32GB and 64 GB (which vary on region), and there's a microSD card slot for those who want to upgrade the capacity (it supports microSD cards up to 200GB).
The camera is a 12-megapixel unit - down from 16-megapixels for the Galaxy S6, although in real terms this shouldn't make much of a difference), a 3,000mAh non-removable battery (an upgrade on the 2,550mAh pack found in its predecessor), and the device is water- and dust-resistant to IP68 (which means it is dust-tight, and waterproof to depths greater than 1 meter).
There's also liquid cooling to keep the handset cool when running demanding apps.
The handset features a micro-USB port for charging and connectivity.
All this is tech wrapped around an Android 6.0 Marshmallow core.
The Galaxy S7 Edge differs by having a 5.5-inch screen with a resolution of 2,560 x 1,440-pixels (which gives it a pixel density of only 534 pixels-per-inch), and the battery is a non-removable 3,600mAh unit (an upgrade on the 2,600mAh pack found in the Galaxy S6 Edge, or the 3,000mAh pack in the Galaxy S6 Edge+).
