Apple has made roughly 100 units of its foldable iPhone referred to as the iPhone Fold, following what is described as a major “breakthrough” in eliminating the familiar crease that plagues most folding phones. These units aren’t just early prototypes; they reflect a significant step forward in Apple’s move toward real, production-level foldable hardware.
The Crease Problem And Apple’s Solution
One of the biggest criticisms of folding phones over the years has been the visible crease along the center of the display when the device is unfolded. This defect isn’t just cosmetic, it’s a very real engineering challenge, emerging from repeated bending and stress on the panel.
Apple’s reported solution comes from a deep redesign: while Samsung is supplying the actual display panel, Apple reportedly took the lead on panel structure, material processing, and lamination, working in close concert with hinge-component suppliers. In particular, Apple, together with suppliers like New Rixing and Amphenol, has re-engineered the folding mechanism so that when the panel and hinge are combined, the permanent crease “typical of traditional folding machines” can be avoided.
This isn’t purely theoretical: according to the report, Apple now believes it has achieved a crease-free design, something that would set this foldable iPhone apart from most of its competitors.
Production Moves Into Engineering Validation
These ~100 units reportedly represent the Engineering Validation Test (EVT) phase, a pivotal stage in product development. In EVT, the focus shifts from wild early prototypes to devices that more closely resemble a final production model. These units are meant to test not just functional performance, but long-term structural integrity, materials behavior, and manufacturing consistency.
Part of what makes this development so meaningful is that it signals Apple is no longer working solely in speculative prototype mode. According to sources, a dedicated production line has already been set up by Honghai Group. This suggests Apple is serious about mass production readiness.
Apple’s Engineering Role: Beyond Just the Display
Though Samsung is providing the foldable OLED panel, Apple’s role is proving to be central to the innovation. The company is said to have designed much of the panel’s internal architecture, including how it is laminated and pressed. The hinge design, often an afterthought in other devices is also co-developed: Apple, Amphenol, and New Rixing are jointly responsible for the key bearing components.
This level of involvement underscores how much Apple wants to differentiate its foldable device. Rather than rely solely on off-the-shelf foldable components, Apple appears to be investing heavily in proprietary engineering to eliminate the very flaws that have held back many folding devices so far.
If Apple succeeds in shipping a truly crease-free foldable device, it could shift the expectations for what foldable phones should be. The crease issue has long plagued folding screen designs from multiple manufacturers. A foldable iPhone that minimizes or eliminates that crease could offer a major aesthetic and functional advantage.
Beyond just looks, a crease-free design could also improve the device’s durability and perceived quality. Users often associate creases with long-term wear or structural weakness, even if that isn’t always the case. Apple’s engineering efforts suggest it’s focused on making the foldable iPhone feel premium and robust, not just novel.
The iPhone Fold appears to be entering its pre-production stage. With EVT underway and a dedicated production line already active, Apple could be gearing up for a limited roll-out. The publication suggests that these engineering units are a strong signal: this isn’t experimental anymore, the device is trending toward real-world production readiness.
Past rumors have placed a potential consumer launch around 2026. The device is also rumored to be positioned as a luxury product with one report estimating a price as high as $2,400.
Even with this breakthrough, foldable devices are notoriously difficult to manufacture reliably. Apple may have solved the crease in these early production units, but durability under long-term use, hinge wear, longevity of the flexible display, and material fatigue remain real obstacles.
Moreover, the cost of such a device could put it in a niche market. If Apple prices it around $2,400, adoption may be limited to early adopters or luxury consumers at least initially.
There’s also the question of scale: while ~100 units are meaningful in EVT, it is a tiny batch relative to Apple’s typical consumer-level production. Success in EVT doesn’t guarantee smooth mass production; it just means Apple has cleared a major technical hurdle.
Apple’s reported production of around 100 iPhone Folds after solving its crease problem marks a major engineering milestone. By redesigning the fold mechanism, applying proprietary panel techniques, and working closely with hinge suppliers, Apple may be on the edge of launching a foldable device that truly stands out.
If everything goes according to plan and Apple can maintain quality in scaling, we could be looking at one of the most refined foldable smartphones ever produced. But despite these advances, risks remain: high cost, long-term durability, and manufacturing yield will all be critical to whether this device becomes a mainstream success or remains a niche novelty.
