Samsung shows off its prototype foldable phone. Angela Lang / CNET The foldable phone era has officially started. Samsung introduced the world to its first foldable phone this week, a device rumored to be called the Galaxy X or Galaxy F. This was not a typical announcement with every detail on display as they were for the Galaxy S9 or Note 9 unveiling. Rather, Samsung teased its foldable phone through a short video and by hoisting aloft a working prototype in an executive's hand on stage. Although Samsung never showed the foldable phone up close – not even behind museum glass – the device is plenty real. It's conceptualized enough to earn Google's backing. In fact, Samsung's project seems to have spurred official Android support for all foldable phones, no matter the manufacturer. Meanwhile, Samsung gathered developers in a Wednesday afternoon session to share a few more details, such as the phone's 4.5 and 7.3-inch screen sizes .

Although Samsung never showed the foldable phone up close – not even behind museum glass – the device is plenty real. It’s conceptualized enough to earn Google’s backing. In fact, Samsung’s project seems to have spurredfor all foldable phones, no matter the manufacturer. Meanwhile, Samsung gathered developers in a Wednesday afternoon session to share a few more details, such as the phone’s .
Despite the dribs and drabs of information, the foldable phone’s letter onstage appearance. Here’s what we know – and what’s still to come.
Samsung did not give the foldable phone a name, but rumors suggest that it will be called the Galaxy X or Galaxy F. The “F” could stand for “fold” or “flex”. The “X” might mean “extra” or “10”, since there are 9 Galaxy S phones out – though we do expect to see a Galaxy S10 around March this year.
If we go by Samsung’s definition, a foldable phone is a device with a cellular connection (hence the “phone” part) that looks like a tablet when it’s fully opened and can close to look like your usual phone. Samsung’s prototype has a tablet-like screen that closes inward like a book, butanother foldable phone, has an outward-folding screen, which means the “screen” is on the outside. There is no single definition.
Last year’s ZTE Axon M was an early version of a foldable phone that attached two separate phone screens through a central hinge. Samsung’s foldable phone (and Royole’s FlexPai) appear to have unibody displays that fold at the midpoint. A magnet secures the FlexPai’s screen in the “closed” position.
We can credit the Axon with exploring different new ways to use a dual-screen device; Royole has already adopted some of these, for example, mirroring the content of both screens so people on either side of a table can watch the same video clip. ZTE could very well come up with a second-generation foldable (or “foldable”) phone.
There are two main advantages. Først kan en foldbar telefon mere end din ledige skærmplads. For example, Samsung’s model has a 4.5-inch display that will use when it’s closed. Then the inside opens into a 7.3-inch screen. Du kan argumentere for at du har det ekvivalente av tre skjermer for å jobbe med.
A larger screen gives you an expanded viewing surface, but it also unlocks different ways that you can use your device. For example, Samsung’s foldable display will let you multitask in three areas at once. ZTE’s Axon M lets you use the entire screen for one app, load a separate app on each screen, or mirror the same app on both screens.
Like the Royole FlexPai, this foldable phone will automatically transfer the app or screen you’re looking at in the folded-up “closed” position to the “open” position, and vice versa. We noticed some were here on the FlexPai, but have not had a chance to see how Samsung will handle the transition.
Samsung created a new display for its foldable phone, the Infinity Flex Display. The company said that it had to modify the usual layers that are part of any display (this is what lights up the “screen” you see on your phone). Alle displays zijn gemaakt van lagen, maar ze zijn gewoonlijk gestapeld en unmoving. The Infinity Flex Display uses a new adhesive that Samsung developed to laminate the display layers so they can flex and fold hundreds of thousands of times.
The company also needed to make the Infinity Flex Display thinner than any other mobile display. It cut the thickness of the polarizer layer, which helps make the screen readable, by 45 percent.
Samsung said it will start mass producing the phone in the “coming months.” The foldable phone will probably start selling in 2019, and the latest rumor pegs March. We expect Samsung to hold a separate launch event to introduce the details. Again, this was just a sneak peek.
The short answer is that we do not know because Samsung has not announced it. Men det er lett å gjette at dette vil være en dyr enhet. The Royole FlexPai’s foldable phone for developers costs $ 1,318 for a device with 6GB of RAM and 128GB of internal storage. The version with 8GB of RAM and 256GB of storage goes for $ 1,469.

Since Samsung’s Galaxy Note 9 for power users starts at $ 999, it’s a fair guess that a cutting-edge foldable phone would easily start at $ 1,500, if not more. We can expect Devicemakers like Samsung (and Royole) to justify high prices based on total screen real estate. Na alles, zij reden, je krijgt een tablet en telefoon in één – en de telefoonprijzen zijn alleen maar hoger.
Samsung aims to give its foldable phone battery life that lasts as long as current Galaxy smartphones, said Jisun Park, the engineering director and head of the system software group for Samsung’s mobile business. That’s despite the fact there’s more active screen to drain the battery. The US version of the Note 9 lasted for an average of 19 hours and 20 minutes in.
We do not have access to the design details, but batteries do not bend. Expect a large battery to sit on one side and many of the other components to balance it out on the other. En stor klage vi havde med ZTE Axon M var at det følte sig ubalanceret med halvdelen af batteriet drastisk tykkere og tyngre end den anden halv. Samsung will have to watch out for that.

Almost definitely not. Samsung showed off a prototype model, commenting that the real parts were hidden inside. Samsung is not ready for the public – or competitors – to see a final design.
If there’s one breadcrumb officially left us about the foldable phone’s eventual shape, it’s in the new One UI operating system. The company mentioned that the rounded rectangular edges that form a major design motif are intended to match its devices’ rounded edges. The prototype foldable phone has 90-degree edges and thick bezels. We can anticipate a softer look.
Materials are a big deal because buyers have been conditioned to spend more for aluminum, ceramic and glass. Men FlexPai bruker en plastisk skærm og kroppen til at opnå fleksibilitet og holde omkostninger i check, og ZTE Axon M handler ned kamerakvalitet og andre dele for at holde det overkommeligt.

It is possible that the foldable phone will have at least one plastic screen. When CNET asked, Samsung’s Park suggested during a session for developers that the exterior screen could possibly have a different material topping the display than the interior screen. Vår gissning er at den 4,5-tommers skjermen kan fremstilles fra Gorilla Glass, mens den 7,3-tommers skærmindside kan være fremstillet af plast.
Samsung did not respond to a request for comment.
In general, you’ll start using the foldable phone like you would like your phone, and then open it when you want to take advantage of the larger screen space. Samsung did not share details about how the hardware and software share messages.
Yes, but there’s more. Samsung announced that the foldable phone, and future phones, will run on a redesigned version of Samsung’s custom software called One UI. Samsung is making the One UI beta available this month, but only for Android 9 Pie users. Det er en fair bet som den foldbare telefonen vil starte med Android Pie.
It’s still early days, so we do not have many details about apps. Samsungs unveiled the device at SDC, its developer conference: To get developers on board with the support of the phone. Samsung’s in-house apps, such as SmartThings, will presumably work on the device, and longtime partner Flipboard showed off its initial efforts on an app.
Since the biggest benefit is the ability to multitask – running three apps at one time or accessing more features in one particular app at once – the onus is on developers to create compelling apps that work seamlessly on the foldable phone. Samsung is relying on app developers to help innovate as they did with stylus-compatible apps for the Galaxy Note.
At the moment, Samsung’s design will “turn off” the 4.5-inch screen and open your app on the larger 7.3-inch interior screen, picking up where you left.
Small at this point, but the future looks fierce. The clamshell ZTE Axon M is not a major competitor, and neither is the Royole FlexPai, even though it beat Samsung to a genuinely foldable display. Men vi vet at LG og Huawei har sine egne planer for sammenleggbare telefoner i arbeidene. LG is rumored to launch as early as January at CES 2019.
During an SDC panel Wednesday, a developer asked when Samsung would sell its display technology to rivals. Det besluttede ikke at kommentere den muligheden, men Samsung er et af verdens største displaypanelproducenter. Det er nok det vil til slutt selge teknologien til konkurrenter til bruk i sine egne enheter.
A foldable phone may feel like a pipe dream, but this is one fantasy that may actually come to life. Vragen blijven over de prijs, praktische en gemak van het gebruik van een vouwbare apparaat.
“Our innovation pipeline includes rollable and stretchable displays,” Samsung’s Denison said Wednesday during the presentation.
