Apple has officially acknowledged the iPhone Duo display issue that’s been circulating since the foldable phone launched, confirming that a “small number” of units have shown a cracked inner screen. In a statement given to Bloomberg and 9to5Mac, and shared with The Verge, Apple says it’s aware of the problem and that owners who run into it should contact AppleCare for a replacement.
What’s actually going wrong
The complaints all describe a similar pattern: the hinge appears to tighten over time, and when the phone is opened, the inner foldable display cracks, producing a distinctive bright line running from the center of the screen toward the right side. Some iPhone Duo units started showing cracked screens within days of reaching customers, with at least one Apple Store in Australia reportedly swapping out a broken unit for a new one on the spot.
Apple’s statement, attributed to communications staffer Alex Kirschner, frames the issue as isolated. According to Kirschner, most iPhone Duo units aren’t susceptible to the defect, and on units that are affected, the problem tends to show up quickly rather than developing gradually over weeks of normal use. That’s a meaningful distinction for anyone who’s been using their Duo without trouble so far: if your unit hasn’t cracked in the first stretch of ownership, Apple’s framing suggests it’s less likely to develop the issue later.
What iFixit found inside
Independent repair site iFixit published a teardown of the iPhone Duo over the weekend and offered its own theory for why some units crack. Based on what iFixit found inside, the foldable screen can push against a center bar in the hinge mechanism, which may be the mechanical root of the cracking some buyers have experienced. Apple hasn’t confirmed or denied that specific explanation, and its public statement stops short of detailing a root cause. That lines up with concerns raised in durability testing of the iPhone Duo’s fold, which looked at how the hinge and display hold up under repeated use.
What this means if you own one
Not every unit is affected. Engadget says its own review unit has been fine, as has a Duo that CNET has been folding in a hinge test that has passed more than 55,000 folds so far.
Apple’s guidance is straightforward: if you notice cracking or the telltale bright line on your inner display, contact AppleCare rather than trying to live with it or seek a third-party repair. It’s worth noting that Apple hasn’t said whether this is covered as a manufacturing defect outside the standard warranty window, or offered a timeline for a permanent fix in future production units.
The iPhone Duo was Apple’s first folding phone and launched to considerable demand, with Apple describing interest in the device as extraordinary even as shipping dates slipped for some buyers. A hardware problem surfacing this early in a brand-new product category isn’t unusual for first-generation foldables, but it does add a layer of risk for anyone who hasn’t yet decided whether to buy one.
The bottom line
Apple is no longer treating the cracked iPhone Duo screens as scattered anecdotes; it has confirmed a genuine hardware issue and told affected owners to contact AppleCare for a replacement. The company says only a small subset of units are affected and that problems tend to appear early, which should reassure people whose Duos have been fine so far. Anyone shopping for a foldable iPhone right now may want to watch for further word from Apple on a permanent fix before buying, or at minimum, keep an eye on their hinge and inner display during the first days of use.
