Apple has spent years watching Samsung, Google, and Motorola wrestle with the fundamental weakness of foldable phones: screens that crease, crack, and degrade. Now, as the company prepares what is widely expected to be its first foldable iPhone, evidence is mounting that Cupertino isn’t content to simply match the competition’s durability standards. It wants to surpass them — and it’s pursuing multiple engineering strategies simultaneously to get there.
A new report from 9to5Mac details Apple’s expanding patent portfolio and supply-chain maneuvers aimed at protecting a foldable display from the mechanical stresses that have plagued every folding phone on the market. The company is reportedly exploring advanced cover materials, self-healing coatings, and internal structural reinforcements designed to minimize the visible crease along the fold axis — the single most common consumer complaint about existing foldable devices.
The crease problem isn’t cosmetic trivia. It’s an engineering headache that has dogged the foldable category since Samsung launched the original Galaxy Fold in 2019. Every time a flexible OLED panel bends, the organic layers inside undergo mechanical strain. Over thousands of cycles, that strain produces a permanent deformation visible to the naked eye — and sometimes to the touch. Samsung has reduced the severity with each generation, and its latest Galaxy Z Fold models show marked improvement. But the crease persists. So does consumer hesitation.
Apple, characteristically, has refused to ship a product until it believes the experience meets its own threshold. That patience has cost it market share in a category that, while still niche, is growing. Global foldable shipments reached approximately 18.8 million units in 2024, according to IDC, with Samsung commanding roughly 54% of that volume. But Apple’s absence hasn’t gone unnoticed by analysts who see the category’s premium pricing as a natural fit for the iPhone maker’s margins.
What’s different about Apple’s approach? Multiple things, apparently.
According to the 9to5Mac report, Apple has been developing proprietary cover glass technology that could replace or significantly augment the ultra-thin glass (UTG) layers used in current foldable phones. Samsung’s UTG, manufactured primarily by Dowoo Insys, is roughly 30 microns thick — thinner than a human hair — and sits beneath a plastic protective film. It provides some rigidity but still allows creasing. Apple’s work reportedly involves a hybrid material that combines the scratch resistance of glass with the flexibility of polymer substrates, potentially reducing crease depth by a meaningful margin.
There’s also the matter of coatings. Patent filings reviewed by multiple outlets indicate Apple has explored self-healing surface treatments that could repair minor scratches and surface deformations over time when exposed to heat — including the ambient warmth generated by the device itself during normal operation. This isn’t science fiction. LG deployed a version of self-healing coating on the G Flex smartphone back in 2013, though that implementation was limited in scope and effectiveness. Apple’s patents suggest a more sophisticated formulation, though patents and shipping products are, of course, very different things.
The internal hinge mechanism is another area where Apple appears to be investing heavily. Foldable phones live and die by their hinges. Samsung’s Flex Hinge, Motorola’s teardrop hinge design, and Google’s fluid friction hinge on the Pixel Fold each represent different engineering philosophies for managing the bend radius — the tighter the radius, the sharper the crease. Apple’s filings point toward a variable-tension hinge that adjusts resistance based on the angle of opening, which could distribute stress more evenly across the display surface during folding and unfolding.
And then there’s the question of the display panel itself.
Apple has long been rumored to be working with both Samsung Display and LG Display on foldable OLED panels. But recent supply-chain reporting from The Elec, a Korean industry publication, suggests Apple has also been in discussions with BOE, the Chinese display giant, about foldable panel production. Diversifying suppliers would be consistent with Apple’s longstanding strategy of avoiding dependence on any single component maker — a lesson reinforced during the Qualcomm modem disputes and the Intel modem debacle.
The timing of Apple’s foldable entry has been the subject of relentless speculation. Display analyst Ross Young of Display Supply Chain Consultants (DSCC) has pointed to late 2025 or 2026 as the likely window. Bloomberg’s Mark Gurman has reported that Apple has been testing foldable prototypes internally for years, with form factors ranging from a clamshell design (similar to Samsung’s Galaxy Z Flip) to a larger book-style fold (like the Z Fold series). The most recent reporting leans toward Apple launching a book-style device first, with a screen size in the neighborhood of 7.5 to 8 inches when unfolded.
But size and form factor are secondary to the durability question. Apple knows this. The company’s entire brand identity rests on products that feel premium and perform reliably over years of use. A foldable iPhone that develops a noticeable crease within six months, or whose inner screen scratches easily, would be a reputational risk Apple simply won’t accept.
That’s why the multi-layered approach matters. No single technology — not the cover material, not the hinge, not the coating — solves the foldable durability problem on its own. It’s the combination that determines real-world performance. Samsung learned this iteratively across six generations of Galaxy Fold hardware. Apple, arriving later, has the advantage of learning from those iterations without bearing the cost of public failures like the original Galaxy Fold’s disastrous early review units, which broke within days.
There are skeptics. Some analysts argue that Apple’s perfectionism could cause it to miss the window entirely — that by the time it ships a foldable iPhone, the category may have moved on to rollable or stretchable displays. Samsung has already demonstrated rollable and slidable prototypes at CES. But the counter-argument is straightforward: Apple wasn’t first to market with a smartphone, a tablet, a smartwatch, or wireless earbuds either. In each case, it arrived with a product polished enough to dominate within a few years.
The competitive pressure is real, though. Samsung’s Galaxy Z Fold 6, released in mid-2024, represented a significant refinement — thinner, lighter, with improved crease management and a brighter display. Google’s Pixel Fold successor is expected later this year with its own display improvements. And Chinese manufacturers like Huawei, Honor, and OnePlus have been pushing foldable hardware aggressively, often at lower price points, with devices like the Honor Magic V3 earning praise for their thinness and display quality.
For Apple, the stakes extend beyond hardware. A foldable iPhone would demand significant software adaptation — multitasking interfaces, app continuity between folded and unfolded states, and developer tools for flexible screen layouts. iPadOS already handles some of these scenarios, and Apple’s investment in Stage Manager and windowed multitasking on iPad could provide a foundation. But the transition from a rigid slab to a folding form factor is more than a screen-size change. It’s a rethinking of how people interact with the device moment to moment.
Pricing remains an open question. Current foldable flagships sit in the $1,400 to $1,900 range. Apple’s premium positioning could push a foldable iPhone to $2,000 or beyond, especially if the display protection technologies add meaningful bill-of-materials cost. Whether mainstream consumers will pay that premium depends largely on whether Apple can deliver on the implicit promise: a foldable phone that doesn’t feel like a compromise.
The patent and supply-chain evidence suggests Apple is serious about keeping that promise. Multiple layers of protection — material science, mechanical engineering, surface chemistry — all aimed at the same target. A foldable display that holds up. That doesn’t crease noticeably. That doesn’t scratch when you look at it wrong.
Whether Apple actually pulls it off won’t be clear until the device ships and thousands of users start folding and unfolding it tens of thousands of times. But the groundwork being laid right now tells a clear story: Apple isn’t rushing to market with a foldable phone. It’s engineering its way there, one protective layer at a time.
