• Refined user interface is fun to use
  • 'Swipe to open' app drawer is great
  • The most powerful phone on the market

The Samsung Galaxy S8 is one of the most powerful phones we've ever tested, and anyone who doesn't buy a Samsung because of the user interface is living in past.

That's not to say that everyone is going to love the Touchwiz* UI straight away, but to not even bother checking out a Samsung phone because you didn't like the user interface in 2013 is pointless.

(*Apparently the TouchWiz name has been quietly dropped and it's now 'Samsung Experience', although we've not seen that publicized anywhere).

Things are miles better now in the interface, and Samsung has worked hard making everything appear where it should. 

If Bixby was as powerful as the brand was promising it eventually will be, the interface would be even less of a thing to talk about, as you could just bark all your commands at your phone and it would do what you needed.

But for now you have to keep exercising those digit muscles and swipe around the display to order your favorite takeaway.

The new user interface on the Samsung Galaxy S8 is more sleek and understated than ever before. It's running on top of Android Nougat, but you'd struggle to see that... this is not a phone for the Android purists.

But we like what Samsung is offering here. Long-pressing on the icons brings up contextual menus (3D Touch from the iPhone, anyone?) and the notifications shade looks premium, even if it can be a little bit complex.

One of the biggest problems Samsung will face with the Galaxy S8 and S8 Plus is the loss of the physical and soft buttons on the front of its handsets.

Samsung fans will be used to having a phone with a home button and back / menu buttons stuck below the screen, but the Infinity Display has seen to it that we don't have those any more.

Instead the buttons are virtual, called up with a swipe of the finger whenever you're using a full-screen app. Samsung has offered a number of tutorials to help users get to grips with this new system, but it takes some getting used to.

There are some nice touches throughout the Samsung Galaxy S8's interface – for instance, when searching through the menus there's a search option at the top, and menus end with options for related settings.

The main change is the loss of the app drawer button – but the tray is still there, it's just accessed with a swipe up or down on the home screen. It's weird to think that this hasn't been used in the past on other mainstream phones, as it makes so much sense and is really intuitive.

Sadly, another potentially cool feature is marred by the poor positioning of the fingerprint scanner. You can swipe down on this sensor to pull down the notifications shade, which saves you jiggling the phone about in the hand to swipe from the top of the screen… well, it would save it if you didn't have to bounce the phone about in your palm in order to hit the fingerprint sensor in the first place.

The Always-on Display, one of our favorite features of the Galaxy S7, has been included and upgraded – now you can even have your favorite photos saved on there to always look at when your phone’s display is turned off.

Device Maintenance is also another neat feature, gamifying your efforts to keep the phone running at optimal levels. This scans your device and offers a score out of 100 depending on the performance of the battery, apps and CPU – encouraging you to keep everything clean and hit 100%.

Every so often you'll be pinged with a note that less-used apps are being put to sleep (which sounds a bit dark) and you won't get notifications until you reopen them, but that's a small price to pay to keep the phone running optimally.

The main thing that's improved with the Samsung Galaxy S8's interface, though, is the overall look and feel of it. The font is clean and crisp, the app drawer sliding up and down is smart, and while the notifications shade can feel like a raucous mess at times, everything has a useful place and there's rarely anything superfluous there.

(Oh, we could mention that the heart rate sensor on the rear of the phone just doesn't work over two different units. For some reason it would recognise a pulse, but be unable to give a readout of an actual number).

If you've been keeping away from Samsung phones because of the interface, then you're a fool. You've been missing out on excellent phones, and they're even better now.

Specs

Weirdly the Samsung Galaxy S8 doesn't have the best spec list out there – but it's pretty close. The phone will come with either Qualcomm Snapdragon 835 or Samsung's own Exynos 8895 chipset inside, both paired with 4GB of RAM.

While the only storage capacity on offer is 64GB, the SIM tray has a slot for a microSD card which can handle anything up to 256GB of additional memory.

The battery is a 3000mAh affair and the screen comes in at 1440 x 2960 pixels, which equates to 570 dots per inch (DPI) of sharpness.

But what does all that mean in the real world? Well, it basically means that Samsung has made one of the world's most powerful phones, with a battery that lasts through a day, a high-res display and loads of storage and which exhibits a real snappiness under the finger.

Our Geekbench tests returned a single-core score of 2008 and a multi-core score of 6630, which is one of the best we've ever seen on test.

In short, there aren't many better-specified phones out there on the market, and at least Samsung is putting some technological substance behind that hefty price tag.
