Some iPhone Duo owners are reporting cracks or bright lines appearing near the center of the inner display within days of the device’s October 23 release, raising early questions about the durability of Apple’s first foldable smartphone.
Apple has not publicly identified the root cause. A key hinge supplier has denied responsibility and threatened legal action, while an unverified allegation about loosened inspection standards has sharpened scrutiny on all sides.
What Users Are Reporting
Early user accounts describe screen damage appearing near the fold shortly after launch, though the full scope of the problem remains unconfirmed.
Coverage citing Chosun and related outlets describes screen damage concentrated near the fold, appearing shortly after launch across multiple reported cases. The number of affected devices and any confirmed failure rate have not been independently established.
One account from an Australia-based user described the inner display failing within six hours and fewer than 20 fold cycles. That is a single user report, not evidence of a confirmed product-wide defect.
Repair specialists iFixit were cited in Chosun reporting as noting that pressure from the folding section on the hinge’s central support may contribute to the reported damage. The same reporting attributed to iFixit a caution that further investigation is needed before drawing firm conclusions about the root cause.
The Allegation and the Denial
An unverified claim from a purported Foxconn employee sits at the center of the controversy, alongside a firm denial from the hinge supplier most directly implicated.
A purported Foxconn employee reportedly alleged that Apple relaxed certain quality-inspection standards ahead of launch to meet demand, potentially allowing defective units to pass inspection. No primary documentation or independent confirmation of this claim exists in available reporting.
The same account reportedly alleged that production lines urgently replaced some materials during the pre-launch period. The specific materials, timing, and whether any substitution is connected to the screen failures remain unverified.
Rejecting those claims outright, hinge-component supplier Fine M-Tec stated that attributing failures in finished products to a specific component requires objective technical verification. The company’s denial establishes only that it disputes responsibility; it does not identify what actually caused the screen damage.
Fine M-Tec went further, saying it is considering civil or criminal legal action against claims that improperly attribute failures to its components or circulate unverified information. The company’s shares reportedly fell more than 15% amid the controversy, according to Chosun market reporting, illustrating how quickly an unverified attribution claim can move financial markets.
Apple’s Position
Apple has acknowledged a limited number of affected units but has not disclosed a cause or confirmed any planned fix.
Reports citing TrendForce say Apple acknowledged the issue affects a small number of iPhone Duo units, though the company has not publicly disclosed the root cause or confirmed whether a design fix is planned. Customers experiencing failures can seek a replacement through Apple or AppleCare.
Production Context
Apple’s reported ambitions for the iPhone Duo help explain why the inspection allegation attracted such immediate attention.
Separate reporting indicates Apple was targeting an increase in iPhone Duo shipments from 9.7 million to 14 million units over the next 12 months, a reported 44% jump, according to TrendForce citing NewsPim. That demand context explains why the inspection allegation attracted attention, but it does not confirm that production pressure contributed to defective units reaching customers.
What Remains Unresolved
The root cause of the screen failures has not been confirmed, and the central allegation against Apple’s production process remains without independent verification.
No confirmed root cause has been established for the screen failures, and the purported Foxconn employee allegation has not been independently verified. If your iPhone Duo develops cracking or abnormal lines near the fold, contact Apple Support directly and monitor Apple’s service programs page for any formal repair or replacement initiative.
