The iPhone Duo’s launch-day promise — Apple’s first foldable for $2,000 — quickly collided with reports of inner displays failing after only a handful of openings. Photos and videos showed a strikingly similar pattern: damage along the hinge, followed by bright lines spreading across the right side of the OLED panel.¹

One Australian owner said the phone had been opened fewer than 20 times when they felt something beneath the internal hinge. “As I continued opening it, I heard an audible crack, and the screen broke right along the hinge,” the customer wrote, adding that an Apple Store replaced the device immediately.¹

As more complaints surfaced, the shared detail was not ordinary screen damage but resistance in the fold itself. Some owners reported a click or snag just before the display failed; others said the defect appeared within a day, or even during setup. The resulting damage looks consistent with a stressed OLED matrix, whose repair could reportedly cost roughly half the price of the phone.²

Teardown analysts then focused on the hinge. iFixit’s scans suggested the apparent failure point sits below the ribbon cable, where the supporting mechanism narrows. Its theory: a support bar may stick and fail to leave enough room for the display’s bend, placing damaging pressure on the panel.² YouTuber CuriousHagi reached a similar, though separate, conclusion after durability testing: a thinner central hinge link appeared to snap at a notch, with marks suggesting contact with the support plate.³

Apple has now acknowledged “an issue impacting the inner display” on a “small number of iPhone Duo units” and told affected customers to contact AppleCare for a replacement.⁴ The company says most devices are not susceptible and that defects appear quickly — a reassurance that leaves the key question unresolved: whether this is a limited batch problem or a weakness built into Apple’s first foldable hinge.
