Display

First let’s look back at the Samsung Galaxy S7. The S7 has a metal frame and a glass back with a 5.1- inch flat screen. There was obviously the later S7 Edge model which had the curved screen. The super AMOLED, 1440 x 2560 pixel (577 ppi pixel density) display has a 72.1% screen-to-body ration and Corning Gorilla Glass 4.

The S8 also sports a metal frame and glass back, however looks quite different. It is slightly longer and not quite as wide as the S7. The S8 will be released in FIVE colors- Midnight Black, Arctic Silver, Maple Gold, Coral Blue and Orchid Gray.

The S8 has a larger 5.8-inch, Super AMOLED, 1440 x 2960 pixel (570 ppi pixel density) curved display, with an impressive 83.6% screen-to-body ratio and upgraded Corning Gorilla Glass 5. The S8 is the first smartphone to receive a Mobile HDR Premium certification for it’s brighter and improved contrast display.

The home button has been removed from the S8, which means the screen is larger with the fingerprint scanner now on the back, where it sits alongside the camera.  The S8 also has tiny bezels above and below the screen, for a more ‘all-screen’ look.

Camera

The S7 features a 12 megapixel, f/1.7 aperture camera, with optical stabilization (OIS) and 4k video recording. The front facing camera is 5 megapixels with f/1.7 aperture.

For the S8 the hardware for the primary camera stays much the same as the S7, with a single-lens 12- megapixel, f/1.7 aperture snapper. The software however has improved, with it’s image processing mimicking Google’s multi-shot technique by combining multiple photos into a single refined image.

Memory

The Samsung Galaxy S7 has 4GB of RAM and either an octa-core Exynos 8890 chipset (in Europe) or a quad-core Snapdragon 820 one (in the US), both of which were among the most powerful mobile chipsets in 2016, and still perform great today.

The S8 sticks with 4GB of RAM, but with an upgraded Qualcomm Snapdragon 835 processor in the US and a Exynos 8895 in Europe and Asia. Samsung says the Galaxy S8 will deliver 10% greater CPU performance and 21% greater GPU performance than the S7.

Other Features

The S8 is the first ever smartphone to support Bluetooth 5.0 (2x speed, 4x range of Bluetooth 4.2) and LTE (4G) speeds up to one gigabit,

Both the Galaxy S8 and Galaxy S7 are IP68 certified, meaning they can be submerged up to 1.5 meters deep for up to 30 minutes.

A major talking point when it comes to the upgraded software is Bixby, a Google Now/Google Assistant/Google Goggles hybrid which shows contextually useful information with a left swipe of the homescreen or via a dedicated button below the volume rocker.

Another, is Samsung Connect - a Google Home/Apple Home rival for controlling your IoT devices, and Samsung Pay (already on the Galaxy S7) which is a credible rival to Android Pay.

So how does the S8 stack up against the S7?

On paper the Samsung Galaxy S8 is a huge improvement on the Samsung Galaxy S7 in some areas, with the screen being the real highlight.

It’s a lot bigger, without making the phone itself massive, and with a new aspect ratio and HDR support it's a genuinely different experience to use.

Elsewhere, the design has been refined and there's quite a lot more power in the Galaxy S8.

If the Galaxy S8 does have your interest, then you can expect to pay $750 / €799 / £689 for the 64GB version.
