The iPhone Duo arrived in stores Friday with the usual Apple launch buzz, long pre-order waits and a $1,999 starting price. Within hours, however, some early buyers reported the same unnerving sequence: resistance at the hinge, an audible crack, then bright lines spreading across the inner OLED panel.

One Australian owner said the phone had been opened fewer than 20 times before it broke along the 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 swapped the device immediately.¹

Over the weekend, the reports multiplied across forums and social media. The damage appeared concentrated in a similar area near the hinge, with lines extending across the right side of the display. Analysts cautioned that online reports do not establish the scale of a defect — and some images circulating online are fake — but the pattern was serious enough to draw a teardown response from iFixit.²

By Monday, Apple had publicly acknowledged the problem. The company said it was aware of “an issue impacting the inner display” on a “small number” of Duo units and directed affected owners to AppleCare for replacements.³ Apple also stressed that early user response had otherwise been positive and that developers were updating apps for the new form factor.

Repair specialists offer a less reassuring interpretation. iFixit said reports commonly describe users hearing “a crunch” while folding or unfolding the phone, and identified an area where the hinge geometry changes near the damage point.² Its broader theory is that a narrowed support section can misalign and press into the flexible display; YouTuber CuriousHagi separately found a thinner central hinge link that snapped at a notch and showed marks where it may have caught against a support plate.⁴

That remains a theory, not Apple’s diagnosis. But for buyers outside warranty, the stakes are plain: Apple lists an inner-screen repair at $999 — roughly half the price of the phone — as the company’s first foldable confronts the old foldable-phone test of whether precision can survive everyday use.²
