Crackgate: The iPhone Duo's Hinge May Be Breaking Its Own Screen

Launch-weekend reports all point at the same line

Apple's first foldable, the iPhone Duo, went on sale on Friday, October 23, and within days owners in Australia, the US, Canada, China and India were posting photos of an identical fault: a thin crack on the inner display directly above the hinge, followed by a bright line of stuck pixels across one half of the screen. Some phones would no longer fold. One Australian owner said the screen broke after about six hours and fewer than 20 opens, with an audible crack while unfolding and no marks on the inner surface or the external hinge.

Apple stays silent while stores quietly swap phones

Apple has not publicly explained the failures and did not return a request for comment. It has also never published hinge endurance figures or a rated fold lifetime in the way Samsung does. Retail handling has been generous so far: most buyers who brought faulty units to an Apple Store walked out with a straight device replacement. The one-year limited warranty covers manufacturing defects, not accidental damage, and direct buyers have a 14-day return window.

Teardown names two suspects above the hinge

iFixit's October 25 teardown, which earned the Duo a provisional 5 out of 10, the highest repairability score it has given a foldable, points at two mechanical suspects: a center support bar that may not drop low enough when the phone closes, and a curved hinge rail that may not retract as it should. The reported damage clusters in one spot, right where the gap for the display cable meets the central hinge support. A pleated flex cable carrying data and power between the halves passes over exactly that point, near the edge of the battery, which could concentrate pressure. iFixit stops short of a verdict, saying more investigation is needed, and notes the inner display and hinge assembly remain the costliest parts to replace.

A robot folded 32,640 times without cracking it

The counter-evidence is striking. Reviewer Joanna Stern built a folding machine nicknamed Hingey and ran her Duo through 32,640 folds over four nights: 17 folds a minute, 8,160 a night, opening to about 130 degrees each time. A calibrated gauge showed slightly greater opening stiffness afterward, which she said she barely noticed, and the screen never cracked. At 20 folds a day, 32,000 folds is more than four years of use, though the machine never fully closed the phone. Deliberate abuse tells the opposite story: JerryRigEverything packed dust into the hinge until it seized and left a permanent green line with a bend test.

Dust makes the hinge crunch

iFixit's fluorescent powder test found less ingress than in the Galaxy Z Fold8 and Pixel 11 Pro Fold, but enough to make the Duo's hinge crunch, matching owners who heard crunching or popping before the bright lines appeared. Cleaning those parts requires removing the flexible display and its supports, and iFixit stresses the test is not an ingress-protection rating. The pattern suggests normal folding should be safe while grit plus mechanical stress may not be.

Early adopters face the steepest repair bill

The Duo starts at $1,999 in the US in Star White and Night Sky, with 256GB to 2TB options. Apple's estimates put inner-display damage at $999 without coverage and $99 with AppleCare+, cover-layer-only replacement at $49, and catch-all "other damage" at $1,499. In the UK the inner display lists at £999, or £79 with cover. Reviews add insult to injury: the under-display FaceTime camera is widely panned as smudgy and over-processed, with testers urging selfie-takers to unfold the phone and use the 48-megapixel rear cameras instead.

What to watch: the return clock and the final verdict

Owners should check their purchase date against the 14-day return window now, push hinge-line cracks with popping sounds through the warranty channel rather than paying for repair, and keep every photo and receipt. Everyone else should wait for two things: iFixit's follow-up findings and any statement from Apple. Those will decide whether Crackgate is a batch assembly flaw or a structural weakness in the hinge itself.
