Apple's First Folding iPhone Is Cracking Along the Crease
Apple spent years engineering the crease out of its first folding iPhone. Owners are now watching the screen break exactly where the crease was supposed to disappear. Reports from early buyers in Australia, the United States, Canada and China describe the same grim sequence: a crunch while folding or unfolding, a small line at the fold, then a bright stripe across the inner display. One Australian owner said the screen cracked after about six hours and fewer than 20 folds.
The reports have piled up fast enough that Reddit consolidated the "crackgate" threads into a megathread in the phone's forum, and iFixit has now taken one apart to find out why. Its teardown, published on 25 October, offers the first engineering clue — and a warning that this may not be a handful of unlucky phones. But nobody, including iFixit, will yet say how widespread it is, and Apple has said nothing at all about the cause.
The crunch, then the line
The failure stories share a shape, and that shape is what makes them hard to dismiss as drops and accidents. Owners describe a noise while opening or closing the phone, then a line down the fold and a bright line across the display. The damage, in the photos iFixit compared, sits slightly below where the display cable passes through the hinge — not at a corner, not at a random impact point, but at the same anatomical spot on phone after phone.
The Free Press Journal's round-up of the reports, published on 26 October, puts cases in Australia, the US, Canada and China, and notes that early reviews from news outlets reported no such problems. That split — reviewers fine, buyers broken — is the first thing any honest account has to explain, and it cuts both ways. Review units get handled carefully and briefly; buyers fold their phones dozens of times a day. A defect that needs twenty folds to show up would never appear in a review and would appear in a buyer's first evening. The Australian owner who reported a crack after six hours and fewer than 20 folds is, on that reading, not an outlier. He is the test the reviewers never ran.
What iFixit found inside
iFixit built a 3D model of the hinge from teardown footage, patents and CT scans, then compared it with photos of broken screens. Its finding, quoted verbatim because the precision matters: "The breaks cluster near the transition from the gap for the crossing flex cable to the central hinge support." In plain language: where several edges meet and change how the thin screen is supported as it bends.
The leading hypothesis comes from a closing simulation. The centre support bar may fail to drop far enough, so the curved fold of the screen comes down onto it and creates a small stress hotspot near the reported breaks. iFixit presents this as one possible answer, not a confirmed cause, and lists other possible culprits — including curved rails that rise above surrounding components while the phone folds. It also doubts the accordion-pleated flex cable itself is to blame, and notes the physical damage is probably smaller than it looks: a tiny fault in the display's electrical connections can knock out a whole row or column of pixels, which is why a hairline fault reads as a bright stripe.
We compared the owner reports against iFixit's teardown findings and the relay coverage — the break location matches in every account we read, from the Free Press Journal to Notebookcheck to the specialist teardown relays. That consistency does not prove iFixit's hypothesis, but it does rule out the comforting explanation that these are unrelated accidents. Same spot, same sequence, same phone.
The teardown found two more things worth knowing. First, dust: in iFixit's glow-dust test, less powder got in than in its Galaxy Z Fold8 and Pixel 11 Pro Fold tests, "but enough reached the hinge to make it crunch" — and iFixit stresses this is not an IP test, since IP ratings cover the enclosure, not a foldable's hinge mechanism. Second, the crease trick itself: the nano-texture cover layer scatters reflections to hide the fold, but with it removed, iFixit says the crease is "arguably even more visible" than the Fold8's, and the surface underneath scratches more easily. Apple hid the crease with light. The failure is happening underneath the trick.
The reviewers who didn't break one
Fairness requires the other side of the ledger. YouTubers Tim Pan and Joanna Stern put the Duo through thousands of folds without a crack, though wear showed. Early reviews from news outlets reported no failures. And iFixit, in the same teardown that found the stress point, gave the Duo the highest repairability score it has ever handed a foldable — a provisional 5 out of 10, against 4 out of 10 for the Galaxy Z Fold8 and the Pixel 11 Pro Fold — writing: "This is the most repairable foldable smartphone we've seen so far, and it's still going to be a bear to repair."
So which is it — a phone that breaks in an evening, or a phone that survives thousands of folds? Both accounts can be true, and that is the problem. Nobody has published a denominator: not how many Duos Apple has sold, not how many have cracked, not what fraction of early buyers are affected. JerryRigEverything's bend test, which left a permanent green line across the inner display that eventually stopped responding, and found the inner screen scratched at level 2 on the Mohs scale, is a stress test, not a census. Until Apple publishes numbers or acknowledges a defect, "crackgate" is a description of a pattern, not a measurement of a population. Anyone quoting a failure rate today is inventing it.
Apple's silence, and the $999 number
Apple did not reply to requests for comment from The Verge or 9to5Mac, according to the teardown coverage. Its own iPhone Duo hinge troubleshooting page, published on launch day, lists symptoms including "Bent or broken hinge" and "Unexpected noise while opening or closing the device", and tells technicians that "there aren't diagnostics or software remedies for hinge issues" — replace the inner display assembly if checks fail. The page does not mention screen cracks, and Apple has not said how users should fold and unfold the phone.
That silence leaves buyers with one hard number. iFixit says Apple is offering replacement units for now, but out-of-warranty damage to the inner screen costs $999 in the US. Replacing only the nano-texture cover layer costs $49, or $19 with AppleCare. Most buyers who went to an Apple Store got a straight replacement, the coverage reports, but buyers who went through carriers had a harder time, and one was told the phone must have been dropped. A $999 repair bill for a phone that may have failed on its twentieth fold is the kind of number that turns a support thread into a story — and the kind of number that makes Apple's silence expensive.
Questions readers are asking
Is this a recall?
No. Apple has not acknowledged a design defect, announced a recall, or said how many units are affected. iFixit's stress point is a hypothesis, not a confirmed cause, and the company has not published a failure rate.
Should Duo owners stop folding their phones?
Apple has given no such guidance. The honest advice from the evidence so far: if your Duo makes a crunching noise while folding, or shows a line at the crease, take it to an Apple Store promptly — replacements are being offered for now — and keep your proof of purchase, since carrier channels have reportedly been harder to deal with.
What does the warranty cover?
Out-of-warranty inner-screen damage is $999, per iFixit; the nano-texture cover layer alone is $49, or $19 with AppleCare. Whether a cracked inner screen counts as a warranty defect or accidental damage is, for now, being decided store by store — which is itself part of the problem.
The verdict: the fold is the product, and the product is failing there
A folding phone has exactly one job its slab siblings do not: fold, thousands of times, without breaking. Everything else about the Duo — the cameras, the software, the thinness — is secondary to that hinge. So the location of these failures is not a detail, it is the verdict on the design: the screen is failing where it bends, at a spot where iFixit found a plausible stress hotspot, on phones that in some cases had barely been folded at all.
Whether this becomes a footnote or a "crackgate" will be decided by two things Apple controls: numbers and words. Numbers — how many Duos have cracked, out of how many sold — would tell buyers whether this is a tolerance problem or a tragedy of the commons. Words — an acknowledgment, a repair programme, a folding guide — would tell owners what to do. Until Apple supplies either, the most repairable foldable iFixit has ever tested is also the one whose owners are photographing their broken screens and wondering whether the twentieth fold will be the last. That contradiction is the story, and it is entirely of Apple's making.
