Apple shares fell 1.44% pre-market after iPhone Duo screens began showing signs of damage, raising concerns about a potential redesign of the hinge. According to BlockBeats, on October 26th, Apple's US stock price fell 1.44% in pre-market trading, based on data from Bit.com. The issue stems from the fact that since its launch in major markets on October 23rd, Apple's first foldable phone, the iPhone Duo, has been experiencing screen damage near the hinge. Photos uploaded by users show white, radial cracks extending from the center of the hinge to the lower right corner of the screen on some devices. Industry insiders believe that the concentration of defects in the same location on the hinge may be related to the hinge design, potentially forcing Apple to redesign the structure. Reports indicate that Apple faced hinge supply issues during the development phase. Its original primary supplier, Amphenol in the US, experienced lower-than-expected production yields, leading to its replacement by Taiwan's Shin Zu Shing. However, Shin Zu Shing also faced production difficulties and had previously supplied only "golden samples" that met specific standards. Apple previously stated that the iPhone Duo's hinge contains over 100 components and uses a 3D-printed hinge module. Since the product has entered mass production, Apple may need to address the defect by reducing the number of hinge components, minimizing design changes while still addressing the issue. Reports indicate that the hinge problem could impact product delivery and sales performance. Apple's reported projections to suppliers suggest that by the end of this year, the total component supply for a complete iPhone Duo production run will be approximately 6 million units. Furthermore, component supplier Fine M-Tec has stated that recent product quality issues are unrelated to the assembly of components it supplies. [Original Link]
