Over the years, the Samsung Galaxy S range has developed and changed quite a bit, with each flagship offering a different design to its predecessor – quite recognisably so. However, that seems to have changed with the Samsung Galaxy S7 edge, which looks a lot like the S6 edge with its curved edge display and body comprised of a gorgeous combination of glass and metal.
While some may feel cheated, we're pretty happy that Samsung decided to stick with a design that made the Galaxy S6 and S6 Edge two of the most desirable phones of 2015. You can hardly blame the firm for not fixing something which wasn't broken.
One big change is that the S7 edge is bigger than its predecessor. Instead of offering two different sizes of the phone, Samsung has decided to make the S7 edge the larger option out of the two S7 phones. To this end, it's 5.5in in screen size which is slightly smaller than the 5.7in wielding S6 edge+.
Despite this move, the S7 edge doesn't feel like a huge phone. An impressive 76 percent screen-to-body ratio means that it's actually only marginally bigger than the regular S7 – we're talking 2mm wider and 8mm taller.
At 7.8mm (Samsung says 7.7mm), the Galaxy S7 edge is a little thicker than the S6 edge which means two things. The first is that the camera bump is a lot smaller, 0.5mm, which is nice and there's also room for a bigger battery – although it's still not removable. We'll talk about battery life later on in the review, but for now we applaud Samsung for providing this rather than trying to simply make a thinner phone for the sake of the numbers.
In terms of placement, everything is where it was before (buttons, ports and slots). You might notice that Samsung has stuck with a Micro-USB port instead of moving to USB Type-C (we'll talk about this more in the hardware section). However, what you can't see from the outside is the resurgence of the Micro-SD card slot, which is combined with the SIM-card in one tray. It's a big advantage over the iPhone and some Android rivals, too.

Many Galaxy S6 owners were disappointed at the lack of waterproofing which was introduced on the Galaxy S5. However, it's one of the key design features of the Galaxy S7 edge (and regular model). It offers a rating of IP68, which means it's totally dust tight and can be submerged in up to 1.5m of water for up to 30 minutes. Better still, there's no fiddling with any flaps to cover ports or making sure the rear cover is clipped in properly (as on the S5).
With a very similar design to last year's S6 edge phones, the Galaxy S7 edge looks stunning with glass which almost wraps around to the back – which is also glass. Once again, it's easily in the top best looking phones on the market. A subtle tweak is that Samsung has removed all the silver bezels around the home button, camera, and the module containing the flash and heart rate monitor so things are a bit stealthier.
The design does have its drawbacks, though, as the thin metal frame at the side (due to the edge screen) makes it hard to pick up from a flat surface. The super smooth glass front and back also makes it a very slippery phone. Last but not least is that the back of the S7 edge is still a fingerprint magnet so you'll be wiping it constantly.
We've taken a look at the Onyx Black S7 edge which is blacker than the Galaxy S6 which had a nice blue tint. There's also a Gold Platinum colour and although those are the only ones available in the UK at the time of writing there are also white and Silver Titanium colours, too. The latter of which is a bit overly mirrored for our taste.
Update 20 April: A new pink gold colour option was made available in South Korea today, and is coming to selected markets soon.

There's a lot to talk about when it comes to the hardware on offer with the Galaxy S7 edge. Phones are seriously advanced pieces of kit these days, arguably the most advanced considering how much is squeezed into something which fits into your pocket. We've split this section of the review up into smaller digestible chunks.
As mentioned in the design section, the screen size of the Galaxy S7 edge has jumped to 5.5in. That's in-between the S6 edge and S6 edge+ (5.1- and 5.7in respectively) which makes it seem like Samsung is only going to offer the one size and a shame for those out there who liked the smaller size edge screen. Perhaps Samsung was testing the water with the previous models to see which was more popular.
The size is really the main difference here in terms of the display tech. Samsung has stuck with a Quad HD resolution (1440x2560) instead of following Sony down the 4K route. That's something we're glad of after finding the Xperia Z5 Premium simply unnecessary. A pixel density of 534ppi ensures a perfectly crisp image.
As expected, the firm continues to use its preferred SuperAMOLED screen technology which provides an excellent all-round viewing experience including superb contrast, brightness and viewing angles. Colours are, as usual, vibrant and punchy which results in an impressive effect but some may find it a little over the top. If you don't like the look of the display you can switch the screen mode between adaptive (default), AMOLED cinema, AMOLED photo and basic. These modes adjust the colour range, saturation and sharpness of the screen.
The main reason to buy the Galaxy S7 edge over the regular S7, or other smartphones, is the dual edge display. We'll talk more about what it can do in the software section below, but it looks and feels awesome even when you're not doing anything with it. When you swipe between homescreen panels or the app menu, icons roll satisfyingly off and on the sides. It doesn't have the same impact for scrolling vertically though a web page or watching a video in landscape but it's still nice – most certainly a luxury than a necessity.
As previously the Galaxy S7 features Smart Stay will keep the display on as long as you're looking at it. For example, it will ignore your screen time out and keep the display on if you're reading an article or looking at an image. It's another feature which needs switching on in the settings, though.
It's more a software feature but the Galaxy S7 edge display is 'always on' should you want it to be. This means you can get basic information without even laying a finger on the phone. You'll get information such as the time, date and battery percentage, plus notifications although this seems to be limited to calls and text messages.
What's disappointing is that there's little control over this feature. You can choose between a clock, calendar and image to display, with a few different styles for each and an optional background for the first two. However, you can't choose to switch off notifications for example, or stop the widget jumping around the screen periodically. When it does move – presumably to avoid lighting up the same pixels constantly – it's distracting and occasionally sits annoyingly a fraction off centre. This will, of course, use more battery juice but it's not enough to have a significant impact on battery life.
Making sure the screen switches off when it's somewhere dark like a pocket or a bag is something we thought happened automatically but you actually need to switch this on in the display settings.
Update October 2016: Samsung is rolling out an update to the Galaxy S7 and Galaxy S7 edge that includes the new features introduced by the Note 7’s always-on display (before it was discontinued). These include a new calendar option, a new digital clock to which you can add a custom text signature, the ability to show the current music track, and some enhancements to battery usage that see the always-on display consume just 1% per hour. You can update to version 1.4.02 of the Always on Display in the Galaxy Apps store, or by tapping Settings, Display, Always On Display, About Always on Display, Update.
Although we would have put good money on the Galaxy S7 edge getting the Qualcomm Snapdragon 820 processor in the UK, it's a good job we didn't as it actually has Samsung's own Exynos 8890 chip instead. There's also an upgrade in the form of 4GB of RAM, a rather healthy amount for a smartphone – the Galaxy S6 models have 3GB.
For those of you interested in the technical details, the Exynos 8890 is an octa-core processor which features four 2.3GHz cores and four 1.6GHz cores. The chip will decide which to use based on the task. The GPU is a Mali-T880 MP12 which is a step up from the Mali-T760 MP8 found in the Galaxy S6 edge.
Overall, Samsung says the Galaxy S7 is 30 percent faster on the CPU front and 64 percent faster when it comes to graphics. In our tests, the S7 edge isn't far off these claims.

As well as testing screen sizes with the Galaxy S6 models, Samsung may have also been seeing which storage capacity consumers prefer by matching the iPhone 6S with 32-, 64- and 128GB models. The Galaxy S7 edge, as mentioned earlier, heralds the return of expandable storage. Correcting the lack of a Micro-SD card slot on the previous model is the right move and likely to be why Samsung is only producing the Galaxy S7 edge in a 32GB capacity.
This is a key advantage for the Galaxy S7 in the battle against the iPhone and the Micro-SD slot can support up to 200GB cards. However, despite running Android 6.0 Marshmallow, the phone doesn't allow for Adoptable Storage – a feature which allows a memory card to be viewed as internal storage, combined with the built in storage.
It appears that Samsung has made this decision, in part, to avoid confusing users. It's a shame but not the end of the world; you'll just have to carry on using the memory card in the old fashioned way. You can move apps to SD card on the Galaxy S7 edge via the storage section of the setting menu. Navigate to the apps section of internal storage, select the apps, hit change and choose SD card.
There's no change on the fingerprint scanner front, it's still hidden inside the physical home button which sits below the screen. The button is more discrete as it no longer has a silver rim around the edge.
You can register a fingerprint to unlock the phone with (using a backup password, PIN or pattern) during the initial set up. Thereafter, you can head into the settings to add more of your digits – doing at least both your thumbs will be useful and you can add up to four in total.
The disappointment here is that we've not found the fingerprint scanner on the S7 edge very quick or reliable. We frequently get messages such as 'no match' or 'keep your finger on the home key a little longer'. It essentially is a bit picky so you need to be quite careful about how you touch the sensor which is a problem we didn't even find with the Galaxy S6. It's by no means unusable but certainly frustrating at times.
If the same happens to you, try re-registering your fingerprint. After doing this, we have seen things improve a little. Interestingly, it's not an issue we've encountered on the regular Galaxy S7.
A fingerprint scanner isn't where the Galaxy S7 edge tech ends, of course. Samsung typically likes to cram every little thing it can into a phone.
The Galaxy S7 edge is 4G-enabled, as you would expect, and supports LTE Cat 9 which can provide download speeds of up to 450Mbps and upload speeds of up to 50Mbps. You won't actually see those figures in real life, though.
It's no surprise to see the latest wireless connectivity including dual-band 11ac Wi-Fi, Bluetooth 4.2 LE with aptX, GPS and NFC. The latter will come in handy when Samsung Pay and Android Pay launch in the UK. The heart hate monitor still sits on the back of the phone next to the camera should you find it useful and the Galaxy S7 edge also has SpO2 sensor (uses the same optical sensor as the heart rate monitor) which measures the oxygen in your blood.
You can access the latter features via the S Health app which also tracks your steps and other activity figures like calories and distance. Helpful for the fitness conscious but the heart rate/SpO2 monitor, like the fingerprint scanner, can take a few attempts before getting a reading.
Despite packing in all that tech, Samsung has dropped something from the spec sheet which has been part of its flagship range since the Galaxy S4. The IR blaster (infrared sensor) is no longer so you can't use the S7 edge to control gadgets around the house like your TV or amplifier.
Although Samsung has clearly answered requests for waterproofing and Micro-SD, the Galaxy S7 edge doesn't have a removable battery - the LG G5 does despite its metal design. The saving grace here is that the capacity has been increased to a generous 3600mAh which is 600mAh more than the Galaxy S6 edge+ so we really don't mind that the phone is a little fatter.
Galaxy S7 edge battery life is impressive and over a 24 hour period of what we'd call regular usage we still had 59 percent of the juice left. On that basis, the phone will last a decent two days unless you rinse it with demanding tasks like watching films or gaming. In our battery benchmark using Geekbench 3, the Galaxy S7 edge set a record with 11 hours and 25 minutes and a score of 6855 outpacing the Huawei Mate 8 which lasted 10 hours 15 minutes with a score of 6091.
The regular Galaxy S7 with its smaller battery (3000mAh) managed nine hours and 15 minutes in the same test.
Samsung hasn’t gone with the reversible USB Type-C port and has instead stuck with Micro-USB 2.0. That may surprise some for a flagship phone in 2016 but Samsung told PC Advisor that it doesn't see the value. The same is true when it comes to Quick Charge 3.0 so the Galaxy S7 edge with the Snapdragon 820 processor only supports Quick Charge 2.0.
With the UK model powered by the Exynos 8890, Samsung says the S7 edge can charge to full in 100 minutes using its own 'Adaptive Fast Charging' which you can even switch off in the settings if you're worried about damaging the battery or the phone getting too hot. We found that the S7 edge charged to full in 98 minutes using the supplied charger.
At the end of the day, these are minor quibbles and not only is the Galaxy S7 edge supplied with a fast charger, it also features wireless charging so you'll find it easier to keep topped up if you buy the right accessory.
With regards to photography, you'll find a 12Mp at the rear of the Galaxy S7 edge, the same camera as the regular model. The more astute of you will point out that the S6 Edge had a 16Mp camera, and while Samsung has dropped the resolution, megapixels aren't everything and it has made improvements in other areas. The rear-facing camera features a Samsung Britecell sensor only 1/2.6in in size, a 1.4 µm pixel size, 26mm lens and an f/1.7 aperture.
There's no dual-tone LED flash like some rivals but Samsung does offer optical image stabilisation (OIS) here which helps keep videos smooth and avoid blurry pictures. Low light performance is the big thing being touted by Samsung.
As you would expect, the Galaxy S7 edge can shoot video at 4K (2160p) resolution which is at 30fps. It can record slow motion at 240fps at 720p, shoot HDR video and simultaneously record 4K video while capturing 9Mp still images.

Interestingly, Samsung added a new image type to the S7 and S7 edge - while it wasn't exactly the iPhone Live Photos rival we'd heard rumours about, it's the next best thing. When taking a panorama on a Galaxy S7 edge, you're able to 'play' it back as if it were a video complete with motion, and you're also able to control the direction by swiping the display. It's called Motion Panorama and the effect is somewhat hit and miss depending on the subject.
Taking a photo as standard, the Galaxy S7 edge shoots in a 4:3 aspect ratio so if you want a wider 16:9 you need to dial things down to 9.1Mp at the most. There's no dedicated shutter button as such but you can use the volume buttons instead and the heart rate monitor for the front camera. We love how quickly the camera launches by double tapping the home button, even with the phone locked. You can also shoot quickly with effectively zero shutter lag and quick acting phase detection auto focus.
There are a bunch of different camera modes to choose from so if you don't like sticking with Auto you can launch the Pro mode for detailed control. There's also Selective focus, Video Collage, Live broadcast, Hyperlapse, Food and Virtual shot to name most of them, plus you can download more.
Photo quality is excellent. In fact, in our standard comparison shot of St Pancras, the S7 manages to retain such detail – even when shooting in JPEG rather than RAW mode - that individual bricks were visible where other flagship phone cameras deliver a smeary mess.
Overall, images are a little on the soft side for our liking – lacking the biting sharpness of the Nexus 6P, say. Yet some still exhibit the haloing associated with too much sharpening.
Colours are fantastic, though, and not just on the Super AMOLED screen. Viewed on a calibrated PC monitor, the warm vibrant tones of a spring day looked great, though some will see them as oversaturated.
The f/1.7 lens produces wonderful bokeh (for a phone) but can occasionally become a drawback as the depth of field is narrower than on most other phones. It can mean some people in a group shot are out of focus because they were standing just behind the person you focused on.
At night, things go noticeably downhill. Noise reduction zaps detail and there’s still evidence of noise in the sky of our photo looking out from London Bridge. When there’s a bit more light – say from street lighting or at dusk – photos are markedly improved: as the sharpness of the letters on the street sign show.
When it comes to video, the S7 is hard to beat. It can shoot sharp, detailed footage in UHD mode, albeit at only 30fps. Our favourite mode is 1080p at 60fps, which along with the very effective stabilisation gives super-smooth video with the same saturated colours you see in the S7’s photos.
Slo-mo video was a little disappointing, partly because there’s no support for 120fps at 1080p which you get with the iPhone 6s. The S7 offers only 240fps at 720p (the iPhone’s lower resolution option). Our tests showed that the 240fps mode produces flickery clips, sometimes even in natural light. Needless to say, you’ll need a special app on a PC to watch the footage in slo-mo and not just at full speed.
As with almost every other Android smartphone launching in 2016, the S7 Edge features the latest version of the software, Android 6.0 Marshmallow. However, as of January 2017 the Android 7.0 Nougat OTA update should begin rolling out to users.

Samsung adds its own TouchWiz interface to the stock Android OS which, depending on your opinion, may or may not be a good thing. That said, Samsung has learnt from past mistakes and has trimmed it down nicely, especially with regards to bloatware.
TouchWiz and pre-installed apps
Pre-installed apps on the Galaxy S7 edge include Samsung's own suite (Galaxy Apps, S Health, S Voice, Email, My Files, Voice Recorder, Samsung Gear and Internet) plus Microsoft apps, too (Word, Excel, PowerPoint, OneDrive, OneNote and Skype). Of course, Google's is there also. It's worth noting that you can't uninstall any of them but many can be disabled instead.
TouchWiz means that the user interface is different to stock Android as found on Nexus devices in various areas. For example, the notification bar looks different but you can do things like long press on Quick Setting (Wi-Fi, Bluetooth etc) to navigate to the appropriate settings. While the recent apps menu is the newer card style view, Samsung adds the upday news aggregator feed (not Flipboard any more) to the left of the main homescreen. This can be switched off if it's not your cup of tea but you can't replace it with something else like Google Now without installing an alternative launcher. Also see: Funny things to ask S Voice.
Long pressing on an empty part any homescreen panel brings up customisation options including the usual ability to change wallpaper and add widgets. You also get access to the Themes store if you want to change the look and feel of TouchWiz, plus 'screen grid' which handily lets you fit more onto the screen if you don't mind app icons being smaller.
Edge screen functionality
As we've mentioned, the edge screen is the main reason to buy the Galaxy S7 edge over the regular model. But what exactly can it do apart from look pretty? Let's take a look.
The Galaxy S6 edge (and Galaxy Note edge) seemed like something of an experiment with Samsung not really knowing what to do with the tech but this has been somewhat refined on the Galaxy S7 edge.
Like before, you bring the edge screen to life by swiping inwards on the 'handle' – a grey bar which can be customised in size, position and transparency. When you do, edge panels will appear including the existing people edge and apps edge. These give you quick access to your favourite contacts and apps but you can now place up to 10 apps on the panel instead of five – but not on the People edge which is a shame.
There are other panels – such as Weather, S Planner and Quick tools - and you can decide which ones you want active and in which order. As well as the pre-loaded ones, you can download more from the internet.
A new addition is the 'Tasks edge' which allow you to do more than just open an app. For example you can compose a message, add a contact or take a selfie. You can choose from a range of different tasks but can't create your own from scratch.
Edge feeds ensure you get information like notifications or S Health data via the edge screen. You can also use Edge lighting so that if the phone is face down, you'll know who is calling by the colour of the edge screen – this only works for contacts in the People edge though but at least both sides now light up instead of the one with the handle. A call from anyone not on your People edge simply lights up green.
With the screen off you can swipe up and down the edge screen the side of the handle to bring up information like notifications. The Night Clock remains a feature and will display a clock on the edge at night, as the name suggests. You can choose which hours for it to start and end, plus which side to display it on.
It's an improved experience but still something of a luxury. We haven't found ourselves using it a great deal but perhaps it's something which becomes more natural over time and with a bit of training.
Multi-tasking and one-handed use
Although there's some hype around the Android N developer preview offering the ability to run two apps side-by-side, Samsung lets you do this already. The Galaxy S7 edge can do this with certain apps by long pressing the recent apps button.
If you're thinking the 5.5in screen might be a bit big for your hands, then Samsung has something to help you out. Switch on 'One-handed operation' and you'll be able to reduce the screen size by tapping the home key three times. It's like having a mini phone and you can switch which side it appears on in case you're left handed. You can also adjust the size and position of the keyboard, keypad, calculator and unlock pattern by switching on 'One-handed input'.
Another key software feature is the new Game Launcher. Switch this on and it will automatically group all your installed games into one place (you can add any that are missed) but it that's by no means the good bit. If you're running out of power you can limit the frame rate to 30fps or even pull back on resolution to save power by taking advantage of the Vulcan API.
The Game Launcher will also (optionally) stop any notifications getting through so you do get disturbed mid-game. A set of game tools bring more benefits such as locking software keys, minimising the game and recording the screen while you play. A small icon like a Facebook chat head sits at the side of the screen to give quick access to the game tools and can be moved to where it's least in the way.
