Review of Samsung Galaxy S7

As one of the mobile phone makers dominating market share, Samsung has upped their game with the release of the Galaxy S7. Following hot on the heels of the ever-popular Galaxy S6, they have listened to their customers, and again implemented a micro SD slot, something the S6 was definitely lacking. Why is this important? Well, it puts it firmly ahead of rival Apple. If you want a bigger capacity iPhone, you have to pay for it. With the S7, you simply slot in a micro SD card.

For the purposes of this review, we will only look at the S7 and not the curvy S7 edge, although they are pretty similar.

Overall design

This is a very pretty looking phone. It has its faults, however. Should you, like me suffer from sweaty fingers, you will be leaving fingerprints all over the surface. Although these clean easily, they can be annoying. Invest in a case to solve the problem. The S7 is not much different in design to the S6. The frame is not as angular and definitely a lot smoother. At 7.6mm thick it is wider, while it weighs 20g more than the S6, coming in at 152g. That’s really light for a fairly big phone. You will notice that the camera protrudes a little less from the phone itself. This makes it far more stable on a flat surface like a charging pad.

If you have ever lost a phone to water damage, you will be happy to know that the S7 now has waterproofing. Unbelievably, it can stay in up to 1.5m of water for half-an-hour!

Phone display

Samsung displays never let you down in terms of quality and it is no different with the S7. Again, they have employed the Super AMOLED display system which allows for an incredible sharpness, no matter what you are using the phone for. In fact, the pixel density on the S7 comes in at 557ppi. Although not as bright as some other smartphones, the S7 is easy to use in a variety of light conditions, especially if you have the auto brightness adjuster switched on.


The bane of all smartphones, especially for those of us who use them constantly, the S7 battery is far better than its predecessor. In fact, in testing, it managed to play close to 18 hours of video at a standard screen brightness. This was five hours more than the S6. Even heavy users should see their phone lasting for more than one day as it did during our testing. The great thing about the S7 is its fast charging. In fact, Samsung claims that you can get 50% charge in 10 minutes. Although this is a very bold claim, we have tested it and found it to be true!

Overall performance

The S7 has two different variants when it comes to processors. In the UK, the Exynos 8890 SoC, develop by the company, is preferred. It offers

Overall, expect incredible performance. From general navigation to intensive apps and even 3D gaming, the S7 handles it all easily. Note, when playing a graphic intensive game, the back panel will tend to heat up.

Audio quality is also fairly impressive if you choose not to use headphones. Quality remains high, even when turning up the volume and there is no discernable tininess.


Interestingly, Samsung has actually dropped the camera resolution from the 16-megapixels of its predecessor to only 12 found on the S7. Although this seems strange at first, what Samsung has done is to increase each individual pixel. This allows more light into your pictures, greatly reducing other potential ‘noise’ outside of the subject. With a wider lens aperture, a quarter more light than before now reaches the lens. The phone also features a dual-pixel sensor providing an excellent and very fast autofocus.

In my view, the S7 is the best phone on the market. Apple have a lot to do to catch up!
