Galaxy S7 – Device with 5.1″ QHD Display
Samsung has done a lot over the years to improve the line, however even the S6 wasn’t perfect, and there were still issues that kept it out of the running from being the best possible phone that it could be, which Samsung is looking to address head-on with the new S7.
For many, these issues included the lack of expandable storage, a perceived lack of battery life, and a reduction in dust and water resistance. Even if I never found the camera hump to be an issue, a number of people complained about this issue as well.
With the Galaxy S7, it’s clear that Samsung has taken many of these criticisms to heart as the Galaxy S7 extends the Galaxy S6 design in many areas while resolving many of the criticisms that were leveled at it. To understand the full extent of the changes seen in the Galaxy S7, we can start with some of the basic specs.
Design and Display
Instead of flat glass leading to a metal edge on the display, the display is now covered with 2.5D rounded glass edges which improves the feel of the device when doing edge swipes. The back glass of the phone is also 3D with curved edges as well to improve the in-hand feel which helps to make the phone feel thinner than it really is.
The Galaxy S7 will be available in four different colors: Black Onyx, Gold Platinum, White Pearl and Silver Titanium.
For the US, the 2.15/1.6 GHz Snapdragon 820 represents a return to a custom Kryo CPU architecture and a new GPU with support for Vulkan. For most regions, the Exynos 8 means a move to Samsung Systems LSI’s first custom CPU architecture in a shipping mobile SoC.
The Galaxy S7 phones are also the first to use Vulkan API, which can significantly reduce CPU loads. Vulkan API is the industry’s first that supports mobile devices as well as desktop and consoles, giving users the ability to play high-performance, graphics-intensive games for even longer.
RAM & ROM
The Galaxy S7 also bumps RAM from 3GB to 4GB which should help reduce the rate at which applications are evicted from memory and improve multitasking performance.
In addition, Samsung has added a hybrid SIM card slot, capable of being used with a single SIM card with microSD or a dual SIM, giving the Galaxy S7 expandability up to 200 GB of memory. But despite that added slot, the Galaxy S7 is still dust and water resistant, rated at IP68 which means it is completely dust tight and can be submerged in at least 1m of water for an indefinite period of time.
With the Galaxy S7, Samsung is taking a rather bold step with a move from the 16MP, 16:9 aspect ratio sensor of the Galaxy S6 to a 12MP 4:3 aspect ratio sensor in the Galaxy S7. While sensor format is roughly unchanged at 1/ 2.6”, the pixel size is now 1.4 micron which should significantly increase the number of situations where the image quality is limited by shot noise rather than image sensor noise.
Interestingly enough, Samsung Mobile has elected to forgo a move to RWB color filter array, which replaces the green subpixels of the RGBG Bayer array with clear/white color filters, despite the 3.5dB sensitivity gain promised by Samsung Systems LSI, although it might just be that such a move would entail too much risk from an image processing standpoint at the moment as Bayer color filter arrays are much more mature and well-understood from an image processing standpoint.
The sensor also incorporates dual pixel technology for dramatically improved PDAF usability. The other change to the camera is an increase in aperture size from f/1.9 to f/1.7, which should improve low light performance.
Both models have significantly larger batteries—the Galaxy S7 is 3,000 mAh and the Galaxy S7 edge is 3,600 mAh each model now has enough power to let people watch an entire 13-episode season of their favorite TV show on a single charge, so consumers can concentrate on using their phones longer without worrying about battery life.
Additionally, their wired and wireless battery charging have also been improved, so consumers can power up and keep using their phones faster and easier.
Galaxy S7 and S7 edge will hit the shelves starting March 11. Pre-orders will begin in a matter of days.
