iPhone Duo launch marred by screen defects and hinge failures

Apple's first foldable smartphone, the iPhone Duo, has faced widespread reports of hardware failures just one day after its Friday launch, with prices ranging from over HK$17,000 to nearly HK$28,000, making it the company's most expensive handset ever. Early adopters globally reported severe display defects shortly after unboxing, including vertical black lines along the hinge crease and white digital artifacts on the inner screen. Complaints also mention abnormal clicking sounds from the hinge after minimal use, followed by fractures and color distortion, with at least one affected owner receiving an immediate replacement at an Apple Store. Out-of-warranty screen replacements could cost over HK$8,700, as standard warranty coverage may be denied if damage is attributed to accidental impacts or mishandling. Engineering experts attribute the issues to first-generation structural stress and advise gentle two-handed opening and ensuring the screen is free of debris before closing.
