Apple is reportedly making significant strides in the development of its inaugural foldable smartphone, which is now said to be on track for a targeted September 2026 launch. According to a report from the Chinese site UDN, citing supply chain sources, the “book-style” foldable iPhone has entered the crucial engineering validation stage (EVT), signaling that the device is moving closer to mass production.
The most notable claim from the report is that Apple has successfully conquered the “crease problem” that has plagued nearly every foldable smartphone on the market. If true, the device, allegedly to be called the “iPhone Fold,” would be the first truly crease-free foldable available to consumers, a key differentiator Apple has long sought before entering the category.
The solution to the seamless display issue is attributed to a complex, integrated engineering approach. While the inner foldable display panel is supplied by Samsung Display, Apple has taken responsibility for the panel structure, lamination method, and material processes used to prevent a permanent fold mark.
A key component in achieving the crease-free design is the specialized hinge, which is rumored to adopt Liquid Metal components. This amorphous alloy is renowned for its high durability and strength, which allows Apple to design a slim yet robust hinge that can withstand repeated folding without deforming the screen or creating the visible crease seen in competitor devices.
By moving into the engineering validation phase, Apple appears to have overcome major technical hurdles that had previously led to rumors of a delay beyond the 2026 timeline. The validation stage is a key step before final component lock-down and the ramp-up to mass production, confirming the September 2026 launch remains entirely plausible.
This determined focus on solving the crease problem before release aligns with Apple’s historical strategy of waiting until a technology is mature and refined to its high standards before bringing it to market. The company aims to introduce a highly polished, premium product that sets a new benchmark for the foldable category.
