According to several reports, Apple’s first foldable smartphone, the iPhone Fold, has hit technical snags during the initial engineering validation testing phase, with major concerns arising over the hinge’s reliability. After prolonged, frequent opening and closing of the hinge, issues like loosening, unusual sounds, and inadequate structural stability have surfaced, posing obstacles to large-scale production. Although Apple has tried to bolster hinge durability using cutting-edge materials such as liquid metal, industry production yield rates remain at approximately 65%, significantly lower than the required 85%. Meanwhile, screen creasing problems have been mostly addressed through dual-layer UTG ultra-thin glass and optical transparent adhesive technology. However, the hinge’s mechanical reliability still stands as the one critical challenge that remains unsolved.

As a result, the planned release schedule for the iPhone Fold may be disrupted, with its original autumn 2026 launch potentially pushed back to early 2027 or beyond. The supply chain has already been alerted to production delays, with key suppliers such as Nien Made and Amphenol working alongside Apple to refine hinge manufacturing processes. This setback not only affects Apple’s strategic positioning in the foldable display market but could also open up a window of opportunity for Android rivals like Samsung and Huawei to capture the high-end market segment.
