Apple CEO admits iPhone Duo supply crisis has no end date as hinge cracks spark Samsung ad war

Key points

• John Ternus stated Apple is unable to predict when iPhone Duo supply and demand will balance, with current shipping estimates set for late January.
• Apple reported record Q4 revenue of $114.5 billion, up 12 percent year-over-year, but this figure excludes iPhone Duo sales as the device launched after the quarter ended.
• Ternus confirmed a 'very small percentage' of iPhone Duo units have been returned for display issues, with Apple offering replacements for affected customers.
• Bloomberg's Mark Gurman and iFixit suggest the 'small number' of cracked units could be in the thousands, pointing to a hinge mechanism failure rather than the display panel itself.
• Samsung launched regional ad campaigns mocking the iPhone Duo cracks, offering discounts on the Galaxy Z Fold 8 and citing a 45 percent sales increase in Europe.
• Unverified reports from ChannelNews.com.au claim Foxconn lowered inspection standards and that production yield is only 60 percent, though Foxconn and hinge supplier Fine M-Tec have denied responsibility.

Background

The iPhone Duo launched on October 23, 2026, at a price of approximately $2,000, facing severe supply constraints and scalper markups. Initial reviews were mixed, with critics noting weight and missing features like a telephoto lens, while others praised the hinge design. Apple issued an internal memo to retail staff regarding the display cracking issue shortly after launch, directing customers with problems to contact AppleCare for replacements.

How outlets are covering it

9to5Mac and MacRumors focus on Ternus's direct admission that supply constraints have no clear end date and that display issues affect a 'very small percentage' of units. PhoneArena and Bloomberg's Mark Gurman challenge Apple's characterization, arguing the 'small number' could represent thousands of units and that the hinge, not the screen, is the root cause. Shattered.io and ChannelNews.com.au introduce unverified manufacturing allegations, claiming Foxconn lowered quality standards and that production yield is only 60 percent, while noting Samsung is leveraging the controversy for marketing gains. Fine M-Tec, the hinge supplier, has rejected blame and is reportedly considering legal action against improper attribution.

Why it matters

The ongoing supply shortage and quality issues threaten Apple's first foldable launch, potentially impacting revenue forecasts and brand reputation. The controversy has also benefited competitors like Samsung, which is using the incident to drive sales of its Galaxy Z Fold 8. If the hinge issue proves to be a design flaw rather than a manufacturing variance, Apple may need to revise hardware, delaying its 6 to 8 million unit production target for 2026.

What to watch

Apple is expected to continue replacing affected units, though stock limitations may cause delays. Samsung is likely to continue its ad campaign and monitor sales data for the Galaxy Z Fold 8. Analysts will watch for quarterly shipment data to determine the true impact of the iPhone Duo controversy on the foldable market. Apple may also issue further statements or hardware revisions if the hinge issue proves to be a widespread design problem.
