Let's have a look...


One of the biggest differences between the S7 and S8 is the design, even though there hasn't been a massive departure in terms of design language. 

Unlike previous years, both S8 models (regular and +) will feature the Infinity Edge display. Samsung has also got rid of the front home button, and minimised the bezels as much as possible.

It's a striking design, that makes last year's crop of flagships look instantly obsolete.

The Samsung Galaxy S7 is 142.4 x 69.6 x 7.9mm, while the S8 is slight taller and narrower at 148.90 x 68 x 8mm.

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

Despite being roughly the same dimensions, the S8 packs a 5.8-inch screen (vs the S7's 5.1-inch) and the S8+ features a 6.2-inch display (vs the S7 Edge's 5.5-inch).

Both the S8 and S8+ have a Quad HD+ display, that's a resolution of 2960x1440 pixels.

On the S8 that's a pixel density of 570ppi, and the S8+ it's 529ppi.

That's actually down from the S7 last year, which had a ppi of 577.

That means colours should look more natural on the S8, over the S7.

Specs and OS

Both smartphones run Android Nougat - don't worry, Samsung hasn't switched to Tizen yet.

The S8 has received the typical yearly power boost. The Galaxy S7 packed 4GB RAM and an octa-core Exynos 8890 processor.

On paper at least, it appears Samsung hasn't changed anything about the rear-facing camera. It may have received a software update, which improved the way the images are processed.

We'll have to see how much it's changed over the previous generation

The front-facing camera has at least got more of an update on the S8 though, with an 8MP sensor in place of the Samsung Galaxy S7’s 5MP one.

Worryingly, the Samsung Galaxy S8 has the same, 3,000mAh battery as the Galaxy S7. As we know, larger screen need more power.

Hopefully, the more efficient chipsets will balance it out, and the S8 won't have worse battery life than the S7.

This is another one we'll need to test when we get the phone into review.


The Samsung Galaxy S8 isn't actually all that different from the S7. The battery, camera and OS is all the same.

That's fine though, because the biggest update - that new screen - makes the S8 feel lightyears ahead of the previous generation of smartphones.
