Apple iPhone Duo faces screen failures and cracking reports
Apple's debut foldable iPhone Duo has faced widespread reports of display defects and hinge issues a day after launch. Early adopters reported vertical black lines and white artifacts on screens. Out-of-warranty repairs could cost over HK$8,700, and experts attribute problems to first-generation des
Apple's debut foldable smartphone, the iPhone Duo, has encountered widespread reports of hardware failures just one day after hitting store shelves on Friday, according to The Standard. Retailing from more than HK$17,000 to nearly HK$28,000, the device is the most expensive handset in the company's history.
Early adopters across global markets reported severe display defects shortly after unboxing, including thick black lines cutting vertically across the inner screen along the hinge crease and rectangular white digital artifacts appearing on display panels. Complaints on international discussion boards and social media suggested the malfunctions centered on the handset's internal flexible display panel. Several users reported hearing faint, abnormal clicking sounds from the mechanical hinge after folding and unfolding the phone only a few times, followed by distinct fractures and severe colour distortion running down the central folding seam.
In at least one case, an affected owner brought the defective unit to an Apple Store, where retail staff provided an immediate replacement rather than requiring the customer to wait for formal repairs. Similar grievances surfaced across mainland China, where shoppers posted images and video clips from Apple retail outlets showing demo units and newly purchased handsets exhibiting identical damage along the centre fold. The visual evidence indicated that devices in Asian markets were suffering from the same structural cracking and display corruption reported by Western buyers.
The sudden surge in screen breakdowns has raised concerns regarding manufacturer repair liabilities. Under Apple's standard one-year limited warranty, material or manufacturing defects occurring under normal operating conditions qualify for free servicing. However, should technicians attribute screen damage to accidental impacts, external squeezing, or unauthorised handling, customers could face out-of-warranty repair fees. Official service price schedules show that replacing an inner display module on the iPhone Duo costs HK$8,749.
Francis Fong Po-kiu, honorary president of the Hong Kong Information Technology Federation, explained that cracks and display artifacts along the crease likely reflected structural engineering compromises inherent to first-generation foldable hardware. Fong noted that Apple's design team had to balance chassis thickness, hinge torque, crease concealment, and internal stress buffering without multi-generational market testing. Because assembly tolerances and stress distribution margins were designed very tight to achieve an ultra-slim aesthetic, minor manufacturing variances in specific production batches could easily trigger structural failures at the crease, where mechanical tension is highest.
Fong highlighted that flexible OLED panels and ultra-thin glass layers are exceptionally vulnerable to localised shear stress. He noted that longtime smartphone users accustomed to rigid glass screens frequently operate devices with one hand from an outer corner or open and snap shut the handset with excessive speed and force, creating severe stress points at the hinge junction that sever internal display circuits and induce microscopic fractures. To safeguard the delicate hardware, Fong advised consumers to open the device gently using both hands to distribute pressure evenly along the hinge mechanism, and to check that the screen surface is completely free of dust and hard particles before closing the device.
