Apple admitted on Monday that a small number of its brand-new foldable iPhone Duo phones have a fault in the inner display, just three days after the $1,999 device went on sale around the world, and told owners whose screens crack or fail to contact AppleCare for a replacement. The admission came after a weekend in which early buyers posted photographs of the folding screen splitting along its central hinge — in some cases within hours of taking the phone out of the box.
Apple's full statement reads: "The response to iPhone Duo from early users has been incredibly positive, and we are seeing exciting things from developers who are rapidly updating their apps to take advantage of its unique form factor. We are aware of an issue impacting the inner display on a small number of iPhone Duo units. If users experience issues with their iPhone Duo display, they should contact AppleCare for a replacement." That is the whole of what Apple has said. The company did not say what is causing the screens to break, did not say how many phones are affected, and did not say whether any fix is coming.
The owners' reports follow a strikingly similar pattern. The damage appears on the big 7.6-inch inner display, along the crease where the phone folds: a crack running down the hinge line, often with a bright line of pixels shooting across one side of the screen, and in some units white stains or a touch screen that stops responding. Several owners describe the hinge suddenly feeling stiff or gritty, then a crunching or popping sound as they opened the phone, and then the line appeared. One buyer in Australia said the screen broke about six hours after purchase, after the phone had been opened fewer than 20 times: "I felt something around the internal hinge, underneath the screen. As I continued opening it, I heard an audible crack, and the screen broke right along the hinge." A buyer in Texas said the screen cracked after roughly four folds, before the phone had even finished its first setup. Verified reporting has confirmed more than half a dozen genuine customer cases across the United States, Australia, India, Canada and China, with online tallies of reported cases running higher — though a note of caution is warranted, because a handful of fake, artificially generated "cracked Duo" images have also been circulating, and not every photograph online is real.
The timing could hardly be worse for Apple. The Duo is the company's first folding phone — it opens like a passport booklet, with a 5.4-inch outer screen for use while closed — and it is the most expensive iPhone Apple has ever sold, starting at $1,999. Demand was fierce: pre-orders opened on October 16, delivery estimates slipped to late January within minutes, and Apple capped orders at two phones per customer when sales began on October 23. Analysts at Counterpoint Research expect Apple to sell roughly 6 million Duos this year, which would be about a quarter of all foldable phones sold worldwide. But that same scarcity now cuts the other way: stock is so tight that while some owners have had broken phones swapped on the spot in stores, others have been told to wait for the next allotment, and at least one owner was offered an express replacement only with a hold for the full price of the phone placed on their card.
Apple has published no cause for the failures, and none has been established. The most detailed outside explanation so far comes from the repair specialists at iFixit, who compared the pattern of owner damage against teardown footage, patents and CT scans of the hinge. Their simulation found the reported breaks clustered just below where a display cable runs under the screen, near a central support bar — and their theory is that the bar may be failing to drop out of the screen's way as the phone folds, "creating a small stress hotspot near the reported break location." That is one firm's analysis, not a confirmed finding, and Apple has not commented on it. In the same teardown work, iFixit concluded the Duo is the most repairable foldable phone it has ever tested — small comfort, since replacing the inner display outside this defect programme is priced at $999. Apple, for its part, has been collecting some failed phones for engineering examination, but it has offered the public no evidence and no explanation behind its admission.
For ordinary buyers, the practical position is this. If your Duo's inner screen cracks, shows bright lines from the hinge, or stops responding to touch, contact AppleCare or go to an Apple Store and ask for a replacement — owners do not need an AppleCare+ plan to get the swap, according to the reporting, and people who bought through a carrier should deal with Apple directly rather than the carrier. The second piece of useful news is timing: Apple says affected units tend to show the problem quickly, so a Duo that has folded cleanly through its first days of use is, on the company's own account, likely in the clear. What buyers still do not know is the honest list of unanswered questions: how many phones carry the fault, what is actually breaking inside the hinge, whether Apple is changing anything in production, and how long replacement waits will run while stock stays scarce. On a $1,999 phone — a price that buys certainty as much as it buys a screen — those are not small questions, and so far Apple has answered none of them.
