Apple: Has observed that a small number of iPhone Duo units have internal screen defects, and advises customers to apply for a device replacement.

According to BIT (Bit.com) market data, Apple’s U.S. stock is currently down 1.02%, with its market capitalization temporarily standing at $5.02 trillion. Apple stated in a post that it has noticed internal screen defects on a small number of iPhone Duo units, advising users to contact AppleCare for a replacement. Apple’s first foldable iPhone, the iPhone Duo, has seen consecutive screen damage issues near the hinge since its launch in major markets on October 23. Photos uploaded by users show that some devices have white, ray-like cracks starting from the hinge center and extending to the lower right of the screen. Industry insiders believe the defects, concentrated at the same hinge location, may be related to hinge design, and Apple may have to redesign the relevant structure. Reports indicate Apple faced hinge supply issues during the R&D phase. Its original primary supplier, U.S.-based Amphenol, was replaced by Taiwan’s Xinrixing due to lower-than-expected production yield, but the latter also encountered manufacturing difficulties and had to supply only "golden samples" that met standards. Apple previously stated the iPhone Duo’s hinge includes over 100 components and uses a 3D-printed hinge module. Since the product has entered mass production, Apple may need to resolve the defects by reducing hinge components and other methods while minimizing design changes. Reports note the hinge issues could impact product delivery and sales performance. Apple’s expected supply to suppliers shows that as of the end of this year, the component supply corresponding to the iPhone Duo’s full production capacity is about 6 million units. According to another report, component supplier Fine M-Tec has stated that recent quality issues with related products are unrelated to the assembly of its supplied components.
