[News] Apple iPhone Duo Faces Reported Hinge Defects; Shipment Target Seen Up 44% on Strong Demand

What happened

Apple’s first foldable smartphone, the iPhone Duo, is reportedly facing quality concerns over display damage near the hinge. According to MacRumors on October 26, Apple acknowledged an issue affecting the inner displays of a small number of iPhone Duo units, but did not disclose the cause of the cracking or whether a fix is planned; affected customers have been able to obtain in-store replacements, though limited inventory has left some waiting. According to ZDNet (citing MacRumors), persistent hinge problems during development prompted supplier changes: U.S.-based Amphenol was initially the primary hinge supplier with Taiwan’s Shin Zu Shing as secondary; Shin Zu Shing took over after Amphenol’s production yields fell well below expectations, but reportedly also struggled, having to select units meeting Apple’s quality standards as “golden samples,” and these difficulties delayed iPhone Duo production. Reuters adds that iFixit, via a 3D hinge simulation based on teardown footage, patents, and CT scans, suggested a possible cause: a central support bar may fail to retract properly during folding, placing pressure on the inner display. According to NewsPim, Apple has reportedly asked Foxconn and component suppliers to raise the iPhone Duo shipment target for the next 12 months by 44%, from 9.7 million to 14 million units; industry sources suggest the increase reflects stronger-than-expected initial demand plus additional component stockpiling for potential assembly defects, and Foxconn’s final assembly yield was reportedly around 60% in September, with hinge-related defects potentially further increasing demand for replacement OLED panels. TrendForce notes early screen-failure reports could undermine consumer confidence, with the long-term impact largely depending on how widespread the issue is and how quickly Apple identifies the root cause and repairs or replaces affected units. Separately, per ZDNet, another potential supply constraint is T-glass, a high-end fiberglass yarn used in copper-clad laminates (CCLs) for PCBs, where Japan’s Nittobo holds a near-monopoly and is prioritizing shipments for AI chips made by companies such as NVIDIA, potentially adding pressure to Apple’s supply chain.
