Foldable Phone Timeline 2011–2026: From Flexible Screens to Tri-Fold Smartphones
Foldable phone history from 2011 flexible-OLED prototypes to Huawei Mate XT2, Samsung, Xiaomi tri-folds and Apple's expected foldable iPhone in 2026.
Latest Story
For years, the smartphone industry had one problem it could not solve: screens kept getting bigger, but pockets did not. Foldable phones promised the best of both worlds — a phone when closed and a tablet when opened. The first attempts were fragile, expensive and awkward. But by September 2026, Huawei is selling tri-fold devices from its Guangzhou launch, Samsung is defending its foldable lead, Xiaomi is pushing its own tri-fold into the same week, and Apple is widely expected to enter the category. This foldable phone timeline traces the whole arc, from 2011’s first flexible-display dreams to 2026’s tri-fold race, and asks the question that actually matters now: not whether phones can fold, but whether people actually want them to.
Would You Buy a Phone That Folds Twice?
🧠 Quick Answer
Foldable phones evolved from flexible OLED prototypes into commercial devices that can open like books, flip like classic clamshell phones, and now unfold twice into tablet-sized tri-fold screens. Samsung popularized the modern foldable market with the Galaxy Fold era, Huawei pushed the category into tri-fold designs with the Mate XT in 2024 and the Mate XT2 in September 2026, and Apple is expected by analysts to enter the foldable market as competition intensifies — though Apple itself has not confirmed a device.
Foldable Phones: Key Questions
What the foldable phone story really shows
- Foldable phones exist because smartphone screens hit a pocket-size limit — people wanted tablet-sized screens without carrying a tablet, and folding hinges were the industry’s answer.
- The breakthroughs are not only about screens — hinge engineering, ultra-thin glass, battery-splitting, software multitasking and durability all had to mature together before foldables became usable daily phones.
- Huawei’s Mate XT2 (7 September 2026) starts at 19,999 yuan (about $2,980) for the base configuration, rising to 29,999 yuan (about $4,470) for the top storage tier with a stylus — still a premium-only product, not a mass-market one.
- Tri-fold phones offer the biggest screen jump of any current design, but two hinges instead of one also means more mechanical complexity, more potential failure points and steeper repair costs.
- Apple’s expected entry is not confirmed — analyst reports and prediction markets point to a launch window in late 2026 or 2027, but only an official Apple announcement makes it real.
- Foldables improved fastest on thinness in 2025 — the Galaxy Z Fold7 measured about 8.82mm folded in independent testing, nearly half the thickness of 2019’s original Galaxy Fold.
- Huawei led global foldable shipments in Q2 2026 with roughly 48% share, ahead of Samsung, even as the category as a whole saw shipments dip slightly that quarter.
- Foldables are still a small slice of the smartphone market — roughly 2.5% of global smartphone shipments in 2026 — because price, crease visibility, thickness and durability still decide whether most buyers switch.
The Incredible Shrinking Screen
Tap a design to see how screen size, thickness, hinges and durability actually compare
The smartphone industry isn’t asking whether a screen can fold. It has answered that. It’s now asking a harder question: how much extra thickness, cost and hinge risk a person will accept for a screen that gets bigger in their hand.

Timeline: The Foldable Phone Story, 2011–2026
Newest first — from this week’s Mate XT2 launch back to the earliest flexible-display dreams
Reading this sequence in order shows a pattern: every generation of foldable solved one problem — a crease, a hinge, a price, a durability scare — only to hand the next one to the following generation. The tri-fold race of September 2026 is the newest chapter of that same story, not a separate one.
Huawei Launches the Mate XT2 as Xiaomi and Apple Close In
What happened: Huawei unveiled its second-generation tri-fold smartphone, the Mate XT2, at an event in Guangzhou, powered by its new Kirin 9050 Pro chip built on Huawei’s “LogicFolding” architecture. Pricing starts at 19,999 yuan (about $2,980) for the base 16GB+256GB model, rising through 21,999 yuan, 23,999 yuan and 24,999 yuan tiers (the top one adding a “Lingdun” privacy screen) up to 29,999 yuan (about $4,470) for the 16GB+2TB version with a stylus set. Sales begin on 12 September 2026 — the same week Xiaomi is expected to debut its own foldable and tri-fold devices.
Why it matters: This is the current news hook behind the whole story: Huawei is treating the tri-fold format as a real, repeatable product line rather than a one-off showpiece, and competitors are timing their own launches to respond directly to it. Apple’s rumoured foldable iPhone is expected to enter this same competitive window, though Apple has confirmed nothing officially.
Foldables Get Dramatically Thinner and More Mature
What happened: Samsung’s Galaxy Z Fold7 measured about 8.82mm folded in independent testing — nearly half the 15.5mm thickness of the original 2019 Galaxy Fold — while Honor’s Magic V5 and Oppo’s Find N5 pushed the same thinness race, with Honor claiming (and independent tests disputing) the title of world’s thinnest foldable. Hinges, ultra-thin glass and battery layouts all matured enough that foldables started reading as polished premium devices rather than fragile experiments.
Why it matters: This is the year foldables stopped feeling like a compromise. Thinner bodies, sturdier hinges and better software multitasking made the case that a foldable could be someone’s only phone, not a curiosity alongside a normal one.
Huawei Pushes the First Mass-Produced Tri-Fold
What happened: Huawei launched the original Mate XT, widely reported as the world’s first mass-produced tri-fold smartphone — a device that unfolds twice, using two hinges, into a screen close to 10.2 inches, roughly small-tablet size. It sold at a steep premium and generated long pre-order queues in China.
Why it matters: This is why tri-fold matters at all: it turns a phone into something much closer to a small tablet, going beyond what a single-hinge book-style foldable can offer, and it set up the format Huawei doubled down on with the Mate XT2 two years later.
More Brands Enter the Race
What happened: Google shipped its first foldable, the Pixel Fold, in 2023; OnePlus entered with the OnePlus Open the same year; and Honor and Oppo pushed thinner bodies and stronger cameras with the Magic V2 and Find N3. Competition widened from a two-brand contest (Samsung and Huawei) into a genuinely crowded field.
Why it matters: Competition pushed every maker toward thinner bodies, better cameras and improved multitasking software at the same time — the ingredients that made 2025’s thinness race possible.
Foldables Improve but Remain Expensive
What happened: Samsung’s Galaxy Z Fold2 and Z Fold3 refined hinges and added ultra-thin glass in place of a plastic-feeling cover layer; the Galaxy Z Flip and a revived Motorola Razr brought the classic clamshell shape back with a modern flexible screen; and Oppo’s Find N (2021) offered a more compact book-style design. App continuity and split-screen multitasking software matured alongside the hardware.
Why it matters: This period is where foldables became genuinely usable daily phones for early adopters, even though prices stayed well above flagship slab phones — the durability and hinge-anxiety concerns from 2019 started fading, but the price gap did not.
Galaxy Fold and Huawei Mate X: The Real Beginning
What happened: Samsung’s original Galaxy Fold and Huawei’s Mate X are widely seen as the true start of the mainstream foldable conversation. The Galaxy Fold’s launch was delayed for months after review units suffered screen failures — some reviewers had peeled off a protective layer thinking it was packaging film, others saw debris get trapped under the hinge. Samsung reworked the hinge and screen protection before a delayed relaunch. Both phones carried prices well above $2,000.
Why it matters: This is the moment “foldable phone” became a real product category in the public imagination — and also the moment durability, hinge anxiety and high prices became the defining criticisms every foldable since has had to answer.
First Commercial Foldable Attempts
What happened: Chinese startup Royole unveiled the FlexPai in late 2018, an outward-folding smartphone using a flexible OLED panel, narrowly beating Samsung and Huawei to become the first commercially available foldable phone. It shipped in limited numbers, with a thick, bulky design and rough software.
Why it matters: Being first did not mean being polished. The FlexPai proved a folding phone could technically ship, but it also showed how far the format still had to go before it felt like a real consumer product rather than a proof of concept.
Curved and Flexible OLED Reach Commercial Products
What happened: Samsung’s Galaxy Round and LG’s G Flex brought curved-screen designs to market using flexible OLED manufacturing techniques, though neither phone actually folded — the curve was fixed. They served as a manufacturing proving ground for bending glass and OLED layers at commercial scale.
Why it matters: These were not true foldables, but they helped the display industry solve real manufacturing problems — flexible substrates, curved lamination, durability under stress — that a genuine folding hinge would later depend on.
Flexible-Display Prototypes Create the Dream
What happened: Samsung showed early flexible AMOLED concepts (later branded “Youm”) and other manufacturers demonstrated bendable-display research prototypes, showing off screens that could flex without breaking. None of these were shippable products — they were proofs that the underlying material science was possible.
Why it matters: This is where the idea felt futuristic rather than real: a screen that could bend, shown on stage, years before anyone could actually buy a folding phone. It planted the concept that the rest of this timeline spent the next 15 years trying to productise.
Price Ladder and Durability Checklist
How flagship, foldable and tri-fold phones actually compare, as of September 2026
| Category | Typical starting price | Screen when open | Thickness folded |
|---|---|---|---|
| Flagship slab phone | ~$999–$1,199 | 6.3–6.9 in, single screen | 7–9mm |
| Book-style foldable | ~$1,799–$1,999 | ~7.6–8 in unfolded | 8.9–13mm |
| Flip foldable | ~$999–$1,099 | 6.7–6.9 in / ~4 in cover | ~14–15mm |
| Tri-fold (Mate XT2) | From 19,999 yuan (~$2,980) | ~10.2 in, tablet-sized | ~12–13mm |
| Durability factor | Flagship slab | Book-style fold | Tri-fold |
|---|---|---|---|
| Hinge risk | None | Moderate — 1 hinge | Higher — 2 hinges |
| Dust & water resistance | Usually IP68 | Often IPX8, no dust rating | Limited or unrated |
| Crease visibility | None | Visible, improving each year | Two crease lines |
| Screen repair cost | Lower | High | Highest of any phone type |
The pattern is consistent across every generation: more folding points buy a bigger screen, but they also buy more mechanical risk and a steeper repair bill. That trade-off, not the sales pitch, is what most buyers are actually weighing when they consider a foldable.
