The Galaxy S6 had a flat 5.1-inch display, while the Galaxy S6 edge had a dual-edge, curved 5.1-inch display with edge-specific software feature. In terms of a difference between the two, that's about it. In 2016, Samsung again launched two different variations of its Galaxy S handset—the Galaxy S7 and S7 edge—but this time around the difference was more significant. The Galaxy S7 edge came with a larger, 5.5-inch Quad HD (2560x1440) Super AMOLED display, which is curved on both sides and packs a pixel density of 534 ppi. That's lower than the 577 ppi of the S6 edge and due to the increase in display size. It now has the same screen size as Apple’s iPhone 6S Plus but fits in a smaller footprint. On the other hand, the standard Galaxy S7 retains the S6’s flat, 5.1-inch Quad HD Super AMOLED panel with a 577ppi pixel density. Display Both displays come with Samsung’s new Always-on Display feature, which provides the user with the date, time, and notifications when the device is in sleep mode. This feature has been developed with convenience in mind. The idea is that the user won't need to turn on the device just to check the time or a notification, providing a zero-touch experience. According to the Korean firm, the Always-on feature only consumes 1 percent of battery per hour, and this feature should help decrease normal battery usage as consumers wouldn’t be turning on their devices as frequently as before. Design Design-wise, you may find the S7 and S7 edge to be familiar-looking, and you wouldn’t be wrong. The new smartphones are based on their predecessors’ design language, and that’s not a bad thing. The Galaxy S6 and S6 edge were among the most gorgeous smartphones ever manufactured by Samsung with their metal and 3D glass construction. Now even though they look similar, they aren’t exactly 100% identical. Samsung did tweak the existing design a little bit. Both the front and back glass panels are now more curved and rounded, which, in theory, should improve the durability and ergonomics of the device. Samsung has also made its new devices about a millimeter thicker: The GS7 is 7.9mm thick, compared to 6.8mm on the S6; and the GS7 edge is 7.7mm thick, compared with 7.0mm on the S6 edge. This is to compensate for larger batteries. The Galaxy S7 packs in a 3,000mAh battery, while the Galaxy S7 edge houses a massive 3,600mAh battery. This change should definitely help fix the battery life issues some people experienced with the S6. The minor increase in thickness has also helped decrease the camera hump on the back, it’s now almost nonexistent. The new S7 design is water- and dust-resistance certified (IP68), which means you can submerge the devices under 1.5 meter of water for up to 30 minutes. Processors Unlike last year, Samsung is shipping the Galaxy S7 series in two different processor configurations: quad-core Snapdragon 820 and octa-core Exynos 8890. So far, North America is the only region confirmed to receive the Snapdragon 820 variant, while other regions are expected to receive Samsung’s own Exynos 8 chipset. Even though there’s a variance between the number of CPU cores and the actual architecture of the cores, both SoCs should have identical performance and power efficiency. The new processors are 30 percent faster than the Exynos 7 chip inside the S6, and the GPUs deliver 63 percent better gaming performance than its predecessor. It even has a built-in water-cooling system. The OEM has bundled both configurations with 4GB of LPDDR4 RAM, so multitasking should be a breeze. Storage The devices come with 32GB and 64GB storage options, but most regions will only be receiving the 32GB variant. Furthermore, you’ll be able to expand storage via a MicroSD card slot. Yes, you read that correctly: Samsung brought the MicroSD card support back from the dead. However, you won’t be able to use Android 6.0 Marshmallow’s adoptable storage feature, as Samsung has decided to disable it from its software, hence you won’t be able to extend your internal memory. If you decide not to use an SD card in your device, you could use a second SIM card in its place, thanks to Samsung’s hybrid SIM card tray. Keep in mind that only select countries will be receiving dual-SIM supported models. The Galaxy S7 and S7 edge will be shipped with Android 6.0.1 Marshmallow with Samsung’s TouchWiz UX running on top of it. Edge UX, for the Galaxy S7 edge, has received a major overhaul as well. Samsung is also introducing a brand new Game Launcher, which allows gamers to record their gameplay, minimize notifications, and manage battery consumption. The company has also built-in Vulkan APIs support into its software, which gives users the ability to play high-performance games with lower power consumption. Camera With the S7 and S7 edge, Samsung has decreased the megapixel count of the primary sensor from 16 to 12 megapixels. At the same time, it has added a brighter lens with a wider aperture (f/1.7) and made the actual pixel size bigger, which allows for the sensor to capture more light. The devices also come with Samsung’s new Dual Pixel technology, which helps improve low-light performance and shutter speed while providing more accurate autofocus. Additionally, Samsung will be selling optional covers with wide-angle and fisheye lenses for all the creative people out there. 4K video recording and Smart OIS (optical-image-stabilization) are on board as well. The front-facing camera is still a 5-megapixel sensor but now comes with a wider, f/1.7 aperture lens. Syncing & Charging In terms of connectivity, the GS7 and GS7 edge packs support for dual-band (5GHz and 2.4GHz) Wi-Fi 802.11ac, MIMO, Bluetooth v4.2 LE, ANT+, NFC, GPS, GLONASS, 4G LTE, and MicroUSB 2.0. Samsung is still using the old, tried and tested Micro USB port for syncing and charging, instead of the new USB Type-C connector. Samsung said this was to make devices compatible with the Gear VR headset, as it did not believe USB Type-C to be mainstream yet. The smartphones come with wireless charging, fast charging, and Samsung Pay support as well. Colors Both devices come in four different colors variations: Black Onyx, White Pearl, Silver Titanium, and Gold Platinum. In spite of that, the U.S. market will be only receiving the Galaxy S7 in two colors (Black Onyx and Gold Platinum) and the Galaxy S7 edge in three colors (Silver Titanium, Gold Platinum, Black Onyx).
