Apple Confirms Display Flaw in Foldable iPhone Duo After Crack Reports
The company says a small number of units have an inner-screen issue and is directing affected owners to AppleCare, as a teardown from iFixit points to a possible mechanical cause.
Apple has confirmed that some iPhone Duo units are shipping with a flawed inner display, following a wave of user reports showing cracked screens and a distinctive bright line cutting across the foldable panel. In a statement to Bloomberg and 9to5Mac, Apple said it's aware of "an issue impacting the inner display" on "a small number of iPhone Duo units," and that owners experiencing the problem should contact AppleCare for a replacement.
The acknowledgment comes just weeks after the iPhone Duo's launch, Apple's first foldable phone and one of the highest-profile products to ship under new CEO John Ternus, who recently took over from Tim Cook. For a device meant to showcase Apple's entry into the folding-phone category already crowded with competitors, a hardware defect surfacing this early is the kind of story the company would rather not be writing statements about.
The complaints follow a familiar pattern. Users describe the hinge tightening up, and then, when they open the phone, a crack appears on the inner display along with a bright line running from the center of the screen toward the right side. It's the same symptom showing up across multiple reports, which is usually a sign of a mechanical issue rather than random one-off defects. One affected user in Australia said an Apple Store swapped out their device immediately, with the replacement happening "on the spot," according to the reporting.
Apple hasn't detailed what's actually causing the cracks, and the company has not given The Verge an on-the-record explanation of the reports beyond its statement to Bloomberg and 9to5Mac. But outside researchers have started digging into the hardware itself.
What iFixit found inside the hinge
Over the weekend, repair site iFixit published a teardown of the iPhone Duo that offers a plausible mechanical explanation for the cracking. According to iFixit's analysis, the foldable display may be pushing against a center bar inside the hinge mechanism as the phone opens and closes. If the screen is making contact with that internal component under certain conditions, repeated folding could stress the panel enough to crack it, which would line up with the bright-line symptom users have been describing near the display's center.
Foldable phones have wrestled with this exact kind of problem for years. The flexible display itself is the most fragile part of the whole design, and the hinge is the mechanism that has to protect it while still allowing the phone to fold flat hundreds or thousands of times over its life. Samsung and other foldable makers have faced their own versions of hinge-related display failures in past models, so an issue like this isn't unprecedented for the category. What makes it notable here is that it's happening to Apple's first attempt, right out of the gate, and it's showing up across enough units that Apple felt compelled to issue a public statement.
For now, Apple's guidance is straightforward: if your iPhone Duo's inner display is affected, go to AppleCare and get it replaced. Apple has characterized the problem as limited to a small number of units, though the company hasn't specified what that number is or said anything about a broader repair program, a design fix for future units, or whether this will require any kind of hardware change in manufacturing.
That's the open question worth watching. A statement acknowledging "an issue" and pointing people to AppleCare is a short-term fix for the customers already affected, not necessarily a sign the underlying hinge design has been resolved. If iFixit's theory about the screen contacting the center bar is right, Apple would likely need to address that at the hardware level for the issue not to keep appearing in newer units, which iPhone Duo buyers and reviewers will likely be watching closely.
It's a rocky first chapter for Apple's foldable ambitions, and an early test for Ternus as he settles into the CEO role. How Apple handles the replacements, and whether it says anything more concrete about a fix, will shape how much this early stumble actually matters once the news cycle moves on.
