Samsung Galaxy X: the brand's first foldable phone

Samsung Galaxy X

Update: Following Samsung's reveal of its first folding display, a source has provided information on when the Galaxy X might launch and what it might cost.

We could have just gotten our first real look at the Samsung Galaxy X - or Samsung Galaxy F as it might be called - at the Samsung Developer Conference.

Samsung revealed something huge: its first foldable screen, which opens clamshell-style and flattens out for a tablet-size display. The Infinity Flex Display, as the tech is called, is an entirely new direction for Samsung smartphones that required development of new materials and processes to make it functional.

What's less clear is whether we saw the Infinity Flex Display mounted on the Galaxy X itself, or whether that was simply a placeholder phone to show off the screen. Samsung literally revealed it from the shadows to hide the design.

You can rewatch Samsung's keynote from the Samsung Developer Conference on YouTube if you want to see the possible unveiling of the Galaxy X (skip to 1:23:00).

In the meantime, you can read everything we know so far below. The Samsung Galaxy X launch has been rumored for a few years, and the leaks continue to roll in about the firm's fabled foldable, flexible, bendable smartphone.

We've gone through all the flexible Samsung smartphone leaks, from the first reports of a folding phone back in 2011 to the most recent reports naming the Samsung Galaxy X and Galaxy F directly.

There's a lot to unpack from several years, but it now feels like we're getting close to a Samsung Galaxy X launch date, and things are beginning to get a little clearer on what we may be able to expect.

Cut to the chase

  • What is it? Samsung's much-rumored folding smartphone
  • When is it out? Possibly early 2019
  • What will it cost? It'll likely be one of the most expensive phones around

Samsung Galaxy X release date and price

The Samsung Galaxy X release date is now clearer as the company has finally shown off the display it will use. Other details are scarce, but this suggests it's well on the way to launching.

Reports from South Korea have said the Galaxy X won't be on sale until 2019. However, it may at least be globally available when it does land.

More specifically, more than one rumor has now pointed to a proper announcement in February, possibly at MWC 2019. That event takes place at the end of the month, so the Galaxy X probably wouldn't go on sale in that case before March 2019.

You may have to pay a lot for it too as an analyst reckons the Samsung Galaxy X price could reach ₩2,000,000 (around $1,850, £1,375, AU$2,400). That's a price we've heard more than once.

Samsung Galaxy X leaks and news

Our clearest look yet at the possible Galaxy X comes from Samsung showing off the Infinity Flex display it will be using. It's a clamshell design that can be unfolded to provide you with a big tablet screen, or folded down to more of a smartphone size.

Prior to that, in November 2017 we got a look at the possible interface of the Galaxy X, revealing a familiarly Samsung UI, but where each half of the display shows a different screen, rather than just making everything bigger or smaller.

This interface was shown in a patent, which also gave us another look at the possible design of the phone, showing something with a laptop-like design, but a second screen where the keyboard would be.

The announcement of the Galaxy F seems to be on schedule, as in early 2018 an industry source claimed Samsung would likely start producing the phone - which will apparently have a 7.3-inch display - in November 2018, with a launch likely in December or early 2019. That matches what DJ Koh has since claimed.

However, given that we only just got a partial look at the phone, a proper launch in early 2019 seems more likely than December.

But apparently prototypes of the folding phone had already been shown off behind closed doors back at CES 2018, which took place in January.

Meanwhile Samsung's Q4 2017 financial results included claims that foldable OLED panels and phones could be a big money-maker for Samsung in 2018 and beyond - which is yet more evidence that the Galaxy X is coming soon.

In May 2018 we heard that Samsung had apparently changed the phone's codename from 'Valley' to 'Winner' and that the final handset will be made up of three 3.5-inch screens, which can be opened out to tablet size or folded like a book.

Apparently the screens for this device will be ready by November 2018 and Samsung has created a curved battery for the phone with a capacity of between 3,000mAh and 6,000mAh.

Recently we've also heard that the Samsung Galaxy F - which could be the launch name for the phone - will have 512GB of storage, dual-SIM support, and the model number SM-F900U. Apparently the firmware is also in testing, which suggests it's coming soon.

Samsung Galaxy X: 8 years in the making

The idea of a foldable phone isn’t new to Samsung, in fact way back in 2011 the company showed off a prototype of exactly that.

The device looked chunky and awkward, but even back then it somewhat worked, remaining intact after 100,000 folds, with only a 6% drop in brightness at the center, where all the folding action happened.

This clearly wasn’t a commercial product, but later that year Samsung launched a concept video (see it below) of a fully bendable (and transparent) mobile device.

It could fold out from a phone-sized screen to a tablet-sized one, showing Samsung's ambitions for the technology. Now, technology hasn't advanced quite this far, so don't expect the Samsung Galaxy X to be just a folding screen - but the vision is an interesting one.

While a device like the one in the video above is still years away, by 2012 Samsung was already hard at work trying to launch the first generation of flexible or foldable phones, but a report late in the year claimed that problems with the production of flexible screens would hold the first bendy display back until at least 2013.

That didn’t stop Samsung showing off another video of a foldable future though, highlighting all sorts of transparent screens, made from plastic that’s thin, light and flexible enough to fully fold or roll.

And as 2012 came to a close it seemed Samsung might be overcoming its production problems, with another report claiming that its flexible plastic screens were in the final stage of development, with the first phones sporting them likely to land in mid-2013.

Samsung’s bendy plastic screens got a more real-world debut at CES 2013, along with a name – they were now called 'Youm', though it was clear from the flexible prototype on show that Samsung was still far from putting a Youm display on a commercial device.

That was made even more clear when the tech was reportedly hit with new manufacturing issues in April 2013. 

Supposedly the previous problems had been solved, but now Samsung was apparently struggling with the encapsulation technology, which protects the screen from moisture and air damage.

The Samsung Galaxy Round - the starting point for the Samsung Galaxy X?

The closest thing we actually got to a foldable phone from Samsung in 2013 was the Samsung Galaxy Round. This was far from the prototypes and concepts we’d seen, but as the world’s first curved screen smartphone it was a big step in the right direction.

That was followed up by the Samsung Galaxy Note Edge, which curved in a now more familiar direction, one which Samsung has since fully embraced and features in its latest flagship handsets including the Galaxy Note 9, Galaxy S9 and S9 Plus.

These are still far from being foldable, and while a Samsung executive did promise a truly bendable device by the end of 2014, whatever he was referring to never appeared.

Talk of foldable phones went a bit quiet until mid-2015, when it was rumored that an upcoming phone codenamed Project Valley could be foldable.

At this point little was known about the device, which would apparently have two screens, but it was said to be in early development, so was unlikely to arrive for a while, if at all.

In September 2015 an "insider" claimed that we’d see a bendable phone in January 2016. It wasn’t clear whether this was Project Valley or not, but apparently it would come in both mid-range and high-end flavors. Though, of course, it didn’t arrive at all.

In May 2016 Project Valley got a new name – the Samsung Galaxy X, which was believed to be the name it would release under.

According to reports at the time it would be ready for release in 2017 and would have a foldable 4K display, so that the resolution would remain high even when the phone was folded.

We were sceptical about that launch date at the time, and were right to be, as we're now in 2018 and still haven't seen it - though we might be about to.

Samsung's roll-up, non-touch display at SID 2016

But that’s not quite the full story so far. At SID 2016 Samsung showed off a roll-out display (above) – but one which didn’t have a touchscreen layer, which would be pretty vital for a smartphone.

Then in June 2017 "people familiar with the matter" reported that we might see two foldable phones from Samsung in 2017 - backing up those previous Galaxy X reports.

Supposedly one would fold out from a 5-inch handset to an 8-inch tablet, much like the concept video Samsung showed back at the beginning of our story, while the other would fold in half like a cosmetic compact, along the lines of a folding phone patent we'd already seen.

This 2017 launch didn't happen, but Samsung was clearly on the right track, with another patent looking to solve one of the biggest problems with folding phones – the ability to fold without damaging any internal components.

The patent described an "artificial muscle", which would move in time with the screen bending to protect other components.

Another patent, spotted by GalaxyClub, highlighted a long device, with a shape more like a remote control than a smartphone, but one which could fold down to half the size.

The shape doesn’t seem particularly practical, so we doubt this is the form the Galaxy X will take, but it’s vaguely along the lines of the phone-to-tablet convertible we’ve been hearing about, and a similar design has popped up since.

One of the more recent bits of information that may point to the foldable X looks different than previous info. Much like the ZTE Axon M that came out in 2017, images from a patent filing (shown above) show off a bezel-licious device that folds in a clamshell design. 

So there were lots of signs of the phone being developed, and according to some sources, more than 100,000 units were going to roll out in the third quarter of 2017 - though they added that plans for a 2017 launch could apparently be changed, which has clearly happened if any such plans ever existed.

That gelled with a tweet from tipster @mmddj_china, who claimed the Galaxy X would land in Q3 of 2017 - which again, obviously, did not happen.

Elsewhere we were hearing that Samsung would only have a prototype ready by then, and supply chain sources speaking to DigiTimes said that a small production of foldable handsets would be made in Q4 of the year, but technical issues may mean we wouldn't see mass production before mid-2018 - yet another false prophecy.

Other sources similarly said that several thousand dual-screen prototypes might land in 2017, but that a commercially available product wouldn't.

One of Samsung Display's own engineers has claimed we haven't seen a foldable phone yet "because the bezel-free display currently sells well, we still have enough time to develop foldable display. The technology is expected to be mature around 2019."

Although more recent news comes direct from Samsung's mobile boss, and is a little better, as he claimed the company was aiming for a 2018 launch, assuming it could overcome certain unspecified problems. Though he's since slightly backtracked on those claims.

More recently still he's said that rather than being the first the company's goal is to make meaningful products and "roll out new products worth paying for".

A polished product is probably worth waiting for, but it seems the wait might almost be over, because, as noted above, Samsung has now shown off aspects of its folding phone, which is a good thing too, as the foldable Royole FlexPai phone is already available.
