When the $1,999-and-up iPhone Duo reached stores on Friday, Apple’s first foldable arrived with the usual launch-day excitement — and an unwelcome warning sign. Within hours, owners began posting images of inner displays split along the hinge, often with bright lines spreading across the right side of the panel.¹

One Australian buyer said the phone had been opened fewer than 20 times before it resisted during opening. “As I continued opening it, I heard an audible crack, and the screen broke right along the hinge,” the customer reported, adding that an Apple Store swapped the device immediately.² Other accounts described the same sequence: resistance, sometimes a click or crunch, then permanent OLED damage.

Over the weekend, teardown specialists began looking beneath the glass. iFixit’s Shahram Mokhtari said the damage appears to cluster where the flexible display can meet a changing section of the hinge support. The concern is a stress “hot spot” — a spot where the bar may not drop far enough to give the bending screen adequate clearance.³

A separate teardown by YouTuber CuriousHagi reinforced that suspicion. After reproducing a break during durability testing, he found a thinner central hinge link snapped at a notched section, with marks suggesting it may have caught against the support plate.⁴ Neither finding proves a universal defect, but both point to a mechanical explanation rather than ordinary screen wear.

By Monday, Apple had acknowledged the reports, saying it was aware of “an issue impacting the inner display” on a “small number of iPhone Duo units” and directing affected customers to AppleCare for replacements.⁵ The company also stressed strong early reception and app-development momentum.

That leaves the real question unanswered: whether this is a contained manufacturing variation or the kind of first-generation foldable flaw that grows more visible as more phones are opened and closed. Mokhtari’s view is cautious: most users appear unaffected, but persistence of the same failure pattern over the next few months could turn an awkward launch-week problem into recall territory.³
