Here is what the record actually shows about who is on the hook. [Apple](https://theinference.org/markets/companies/apple)'s first foldable [went on sale on October 23](https://theinference.org/article/apple-s-foldable-opens-for-preorder-october-16-and-in-china-its-ai-is-alibaba-s) [1]. Four days later, owners were posting photos of the same wound: a bright line of dead pixels and a thin crack running along the inner display's crease, on phones that had barely been folded. One buyer in Australia heard his screen give way with an audible crack six hours after purchase, fewer than 20 fold cycles in [1]. Apple has confirmed the problem exists, in [a statement describing "a small number" of affected iPhone Duo units](https://www.msn.com/en-us/news/other/iphone-duo-screens-crack-at-the-hinge-heres-whats-breaking-inside-apples-foldable/ar-AA2gb71b), and is handing out replacements through AppleCare, standard warranty included, no paid plan required [4]. ## Blame is moving faster than the evidence A purported [Foxconn](https://theinference.org/markets/companies/foxconn-hon-hai-precision-industry) employee at the Zhengzhou plant [claims Apple relaxed quality-inspection standards to keep launch supply moving](https://www.tokenpost.com/news/technology/42073), and that production lines urgently swapped materials before launch [2]. No documentation backs that claim; [even sympathetic coverage labels it anonymous and unverified](https://www.gadgetreview.com/foxconn-insider-claims-apple-relaxed-quality-checks-and-defective-iphones-may-have-shipped) [1] [5]. Separately, [reporting citing Bloomberg's Mark Gurman says Apple is itself looking at assembly issues as the likely cause](https://www.androidheadlines.com/2026/10/apple-accused-of-lowering-quality-standards-and-causing-iphone-duo-defects.html), which keeps the allegation alive without confirming it [5]. ## Fine M-Tec denies everything; the market does not wait The supplier with the most to lose, South Korea's Fine M-Tec, has denied everything. The company, known for the metal plate supporting the back of the display, [says the damage "is not attributable to a quality defect in the components we supply"](https://www.ithinkdiff.com/fine-m-tech-iphone-duo-hinge-stock-falls/) and that no single part can be blamed without objective technical verification. It is weighing civil and criminal action against unverified attributions [3]. The market did not wait for the forensics: Fine M-Tec shares fell 15.7% on October 26, closing at 9,400 won, while Apple's stock slipped about 0.5% [3]. ## The teardown points at tolerance, not materials The iFixit teardown points at a tolerance problem, not a materials problem: the hinge's center support bar may fail to retract far enough when the phone closes, pressing the display against a concentrated stress point exactly where the breaks appear [4]. That is the kind of flaw that hides until production scale exposes it, and it implicates design and assembly, which spreads the blame across Apple, Foxconn and the hinge module makers (the hinge alone has more than 100 parts) rather than landing on one supplier [3]. ![Close-up of the folded iPhone Duo's hinge edge and outer screen](https://storage.googleapis.com/theinference-public/img/03f16aa5ecc8fce8.jpg) *The folded iPhone Duo's hinge edge. The hinge module has more than 100 parts and sits at the center of the blame question. (SimonWaldherr)* ## Who actually pays The costs are documented. An out-of-warranty inner-display replacement runs $999, half the device's $1,999 price; with AppleCare+ it is $99 [4]. Every affected unit Apple replaces for free is a warranty line item landing in the holiday quarter, on a product Apple was reportedly targeting to scale from 9.7 million to 14 million units over 12 months, a 44% jump [1]. *Chart: **A cracked Duo screen costs half the phone's price to fix without coverage** Bars comparing the iPhone Duo's $1,999 starting price, the $999 out-of-warranty inner display repair and the $99 AppleCare+ repair.* *US dollars. Starting price and repair pricing per iFixit teardown reporting (Latin Times, October 27, 2026). Sources: [4] [4]* ## Two verdicts would settle who pays Two things decide this. Whether Apple's own assembly investigation, per Gurman's reporting, produces a named cause [5]. And whether a formal service program appears on Apple's support page, which would convert a "small number" into a recognized defect class [1] [4]. Samsung survived the same scare with the original Galaxy Fold in 2019 by delaying and redesigning; Apple's first foldable now faces its version of that choice before the holiday quarter [4]. The stock that already paid, Fine M-Tec, is waiting for the verdict (invezz.com's market-note on Apple's premarket dip was blocked by a bot check and could not be read for this piece). ## Takeaway Apple is replacing iPhone Duo screens for free after crease cracks appeared within days of launch; the cause is unproven, the Foxconn inspection claim is unverified, and Fine M-Tec's 15.7% share drop prices in blame the record does not yet support. ## Sources 1.
