The bezel-less phone is a concept started at the end of 2016 by Xiaomi's Mi Mix, and since then we've had all manner of phone makers attempt to get even closer to the idea of a phone that is all screen and no bezels. Samsung's Infinity Display is one of the best attempts so far, but in 2018 we could see it follow the route Apple has taken with the iPhone X and minimise the top bezel even further.
Rather than a thin strip at the top in which to house the sensors, camera and speakers the iPhone 8 features a notch at the top and then minimises the bezels to the left and right of this. It's not an attractive design, but it does allow for a higher screen-to-body ratio. Patents unearthed by Galaxy Club suggest Samsung has the same idea.
Something we haven't seen before is the super-slo-mo video-recording functionality thought to be coming to the Galaxy S9 - an amazing 1000fps.
Gone are the days when manufacturers wait for big tradeshows to announce their new phones. We'd already heard that LG could be announcing its next G-series flagship earlier than usually in 2018, potentially in January. Now it appears Samsung could be following suit, with an announcement in January and onsale date in mid-February.
This theory is part speculation, based on the fact the upcoming iPhone 8 could be the best iPhone upgrade we've seen in a long time and could hit Samsung's sales hard, and part factual, given that Samsung Display will start shipping OLED panels for the phone in November, which is two months earlier than usual.
Samsung is also said to have begun working on the Galaxy S9 back in March 2017, and it's even further ahead than we imagined. We're amazed to discover that what is thought to be the Galaxy S9 with a Snapdragon 845 processor was spotted on Geekbench as early as July 2017, which does indeed point to be an early release.
Samsung’s Galaxy S8 went on sale in April 2017, but both it and consumers are always looking for the next best thing. Samsung has a reputation to keep, with its S-series flagship crowned best smartphone three years running. (Also see our Samsung Galaxy S8 and Galaxy S8+ reviews.)
Its Galaxy S series is renowned for combining premium design, the latest features and unbeatable performance, and we expect to see more of the same in 2018. And so we look ahead to the Samsung Galaxy S9 and S9+, reportedly codenamed ‘Star’ and ’Star 2’, for which the rumours are already rolling in.
As in previous iterations, we expect there will be two versions of the S9: a standard model with a 5.8in display, and a Plus model with a slightly larger 6.2in screen. Both will feature the dual-curved edge and Infinity display, but new to these phones will be the in-display fingerprint-scanning tech rumoured for the Galaxy S8, as well as higher-capacity batteries (enabled by a new type of motherboard).
We would be amazed if they didn't also get the Note 8's dual-camera, which combines two 12Mp telephoto and wide-angle lenses, both with OIS.
We don't think the design will change much, but there are reports that the Galaxy S9 could have a modular design - not that this turned out so great for the LG G5. Samsung is allegedly planning to introduce magnetic pins on the back of the phone that will allow the attachment of external modules. Until we hear more on that front we'll take it with a pinch of salt.
Features were standardised across the line with the Galaxy S8 and S8+, so expect only minimal differences in those specifications affected by the larger screen, such as battery capacity (a larger case allows for a little more juice), dimensions and weight. As such, the rumours you read in this article will be applicable to either handset.
When is the Galaxy S9 release date?
Expected release date: January 2018 announcement, mid-February onsale
Speculating over Samsung Galaxy release dates used to be easy, with the S series unveiled during an Unpacked press conference a day ahead of MWC, traditionally held in late February or early March, and the Note series in a second Unpacked conference the day before IFA at the beginning of September. If that were still the case we'd expect to see the Galaxy S9 announced on Sunday 25 February 2018.
However, in 2017 it announced the Galaxy S8 and S8+ in March, some time after February’s MWC tradeshow. The phones eventually went on sale at the end of April.
And now that it has broken that tradition, rumours are flooding in that the Galaxy S9 will appear even earlier in 2018, rather than later. Samsung display will start shipping OLED panels for the phone two months early in November, and the Galaxy S9 has already been spotted on Geekbench (in July).
All this is potentially leading up to a January announcement, with a mid-February onsale date. And that could be a good idea for Samsung, if the upcoming iPhone 8 is as good as it's rumoured to be - it will need to claw back sales quickly.
How much will the Galaxy S9 cost in the UK?
The Galaxy S8 and S8+ were Samsung’s most expensive S-series phones yet at £689 and £779 respectively. Part of this extra cost can be attributed to the new features, but finances following both Brexit and the Note 7 disaster have almost certainly come into play here, too.
Until this year, Samsung always kept its pricing reasonably constant, and in line with other flagship phone makers. For that reason we’d be surprised to see the price go any higher than the current RRP.
It’s always worth considering with Samsung phones that - more so than with any other manufacturer’s smartphones - SIM-free prices fall rapidly in the few months following launch. As an example, just a couple of months after the Galaxy S8 announcement you can pick one up for £579 from Amazon, a saving of £110.
What are the rumoured new features and specifications of the Galaxy S9?
Samsung reportedly began working on the Galaxy S9 in late March 2017, which would mean it is already six months ahead of schedule compared to where it was with the Galaxy S8 and S8+ last year. And that means more time for quality control, more time for building in new features and, hopefully, more happy customers.
Amazingly, in July 2017 an early version of the alleged Galaxy S9 was spotted in the Geekbench database - that's some seven or eight months before we expect to see the phone announcement. A device with the model name SM-G9650 is listed with a 1.78GHz quad-core Snapdragon 845 processor and just 4GB of RAM. It scored 7371 points in the RenderScript test, which is lower than the Galaxy S8 managed in the same test. There are no performance scores.

An unnamed source suggests the first work on the Galaxy S9 began with the screen, and that there is not expected to be any change with the sizing: so we’ll see a 5.8in Galaxy S9 and 6.2in Galaxy S9+.
The Bell reports that Samsung has already ordered these screens from suppliers, but with one key difference: they will feature the in-display fingerprint-scanning tech that was rumoured for but never made it into the final spec of the Galaxy S8.
We’d expect to see the same 2960x1440, 570ppi, Super AMOLED ‘Infinity’ panel on the S9, and another 529ppi panel on the S9+. Given that Samsung by default limits the screen resolution to Full-HD+ (2220x1080) in the Galaxy S8, we really don’t think it will push up the resolution up to 4K.
It is possible that despite keeping the same dimensions and resolution the display technology itself could be improved. Samsung is reportedly using screen tech codenamed ‘Sunflower’ for the Galaxy S9 - it’s still Super AMOLED, but should improve display fidelity and be more consistent and reliable.
The new virtually full-screen 18.5:9 ratio will also likely remain, as will features such as the always-on display and edge functionality.
Samsung will allegedly implement its Y-OCTA tech into both models this time around, with only the standard Galaxy S8 getting the treatment in 2017 (the Galaxy S8 Plus does not and the Note 8 apparently will not get it either). Y-OCTA uses a single manufacturing process for the screen and the touch-film element.
In 2016 Samsung patented a glass-coating technology that helps water to bounce off the screen, making it much easier to use in the rain. This tech could well be introduced in the Galaxy S9, which will itself most likely be waterproof. (The Galaxy S8 is rated IP68, which means it is resistant to submersion up to a depth of 1.5m for up to 30 minutes.)
According to Aju Business Daily, Samsung is in talks with Qualcomm to help it build the Snapdragon 845, which could be the chipset onboard 2018’s Galaxy S9, plus other flagships. However, it says Taiwan’s TSMC is in the running as well as Samsung (TSMC is responsible for Apple’s A11, another 10nm chip).
The 10nm Snapdragon 835 Samsung helped Qualcomm to manufacture was 27 percent faster and 40 percent more energy-efficient than the company’s previous 14nm chips. The upcoming Snapdragon 845 is said to be built on the 7nm manufacturing process, and will be even faster and more efficient than ever.
(The nm figure relates to the distance between transistors, and the more you can squeeze on to a chip the faster it will be.)
It's worth pointing out that the Snapdragon 845 has not yet been officially announced, though there is evidence from Qualcomm itself that it is planned. Samsung is reportedly buying as many of these chips as it can get its hands on to prevent others using them.
Despite holding the exclusive on the Snapdragon 835, in the UK the Galaxy S8 and S8+ are sold with Samsung’s own Exynos 8895. It’s rumoured that the UK variants of the Galaxy S9 and S9+ will come with an 8nm Exynos processor, possibly the 9810.
Samsung has announced that its next-gen Exynos chips will feature LTE modems that support six carrier aggregation (6CA). A first in the industry, Samsung says this unlocks a max download speed of 1.2 gigabits per second (20 percent faster than the Galaxy S8, which has a 5CA modem). It should allow you to download an HD movie in just 10 seconds, and eliminate buffering.
Storage and RAM
You get 64GB of storage as standard with the Galaxy S8, along with microSD support. That’s already quite generous, so we’re not expecting to see any changes here.
Something we might see in the Galaxy S9, though, is for Samsung to finally push up the RAM allocation from 4GB to 6GB, as it has done for the Note 8. This is by no means out of the question, with some phones that are now a year old offering this amount of memory. It would also help it in its quest for ever-increasing performance.
Although the size of the phone is not expected to change, we could see battery capacity get a boost with the Samsung Galaxy S9. ET News reports that Samsung will facilitate this using a new type of motherboard that uses substrate-like PCB technology to squeeze in more layers of components - or extra room for the battery pack.
Fast charging - both wired and wireless - will likely feature, though we suspect Samsung will continue to use its own Adaptive Fast Charging tech rather than the Quick Charge built into Snapdragon processors.
Samsung traditionally leads the pack when it comes to new smartphone features, so we’re somewhat puzzled by the fact it has yet to introduce a dual-camera. Nevertheless, one has been confirmed for the Note 8, so expect it to feature in the Galaxy S9 too.
Samsung’s Note 8 has a 12Mp dual-lens camera with dual-OIS and 2x optical zoom.
It's been claimed that the Galaxy S9 will be able to shoot incredible 1000fps slow-mo video. This will apparently be achieved using a three-layered image sensor that adds DRAM to the sensor and logic chip, and of which it will begin mass production of in November. This builds on the two-layered approach seen in current high-end smartphones, though Sony has also used a three-layer system in its XZ Premium and XZ1 phones.
Ports and connections
Samsung introduced USB-C rather than Micro-USB for the Galaxy S8, though it didn’t follow the likes of Apple in removing the 3.5mm headphone jack and relying on wireless or USB-C audio. There is a danger it could take that plunge this time around, though nothing has yet been confirmed.
One change we would like to see in the design, and something we hope Samsung will take into account following significant consumer criticism, is the awkward placing of the rear fingerprint scanner. It’s not so much being on the back of the handset that offends us, but how it is wedged in beside the camera as if it were an afterthought.
The Galaxy S9 could be the phone in which we finally see the fingerprint scanner built into the screen glass itself. Qualcomm has announced Qualcomm Fingerprint Sensors, a new ultrasonic technology that allows fingerprint-sensing tech to be built directly into a phone’s OLED screen. It also works in glass and aluminium.
Less revolutionary alternatives might include the scanner taking a more central position below the primary camera, or Samsung taking a leaf out of Sony’s book by building it into the power button on the edge. Or maybe Samsung will go all in with iris scanning. To be fair, any of these options would be preferable to what we have now.
We’re expecting the final version of Android O to be revealed in September or October 2017, with the next version - Android P - not due until the same time next year, well after the Galaxy S8’s anticipated announcement. It’s therefore almost certainly the OS you’ll find onboard the S9 and S9+, albeit with the TouchWiz UI on top.
Samsung also introduced the Bixby AI assistant in the Galaxy S8, which we would have thought would have only got more intelligent for the Galaxy S9.
It is way too early for leaked images of the Galaxy S9 and S9+ (the main image shown on this article is of the Galaxy S8 Plus), though we will publish them here as soon as we spot them.
