iPhone Duo Launch Marred by Early Hinge Cracks and Durability Concerns

Key points

• Early adopters in the U.S., China, and Australia report inner display cracks along the hinge within 24 hours of launch, often after fewer than 20 folds.
• Cracks typically manifest as bright white lines on the right side of the screen, with no visible external damage to the hinge.
• Apple offered express replacements, with some users receiving immediate in-store swaps, though initial phone support required a full-cost hold.
• JerryRigEverything's durability tests showed the inner screen scratches at level 2 on the Mohs scale and failed dust and bend tests, though it did not snap in half.
• CNET has begun rigorous folding tests using a custom machine to compare the iPhone Duo against Samsung's Galaxy Z Fold 8.
• AppleInsider reports that Apple Stores are not seeing a surge in repair requests, suggesting the failure rate may be lower than social media implies.

Background

The iPhone Duo launched on October 23, 2026, marking Apple's entry into the foldable phone market, which Samsung has dominated for seven years. Prior to launch, concerns about durability were raised, but the device was priced at $2,000. Apple released DIY repair manuals on October 24, coinciding with early reports of hinge cracks. The device features an IP68 rating, but tests show dust can enter the hinge, overpowering the magnets designed to keep it closed.

How outlets are covering it

Tom's Guide and The Verge emphasize the immediate and widespread nature of the hinge cracks, citing Reddit posts from multiple countries. They highlight the consistency of the failure pattern and Apple's initial response, which included express replacements. In contrast, AppleInsider downplays the severity, noting that Apple Stores are not flooded with repair requests and that the device is more durable than perceived. JerryRigEverything's tests, cited by Tom's Guide and AppleInsider, show the device fails dust and bend tests but survives extreme stress better than expected. CNET focuses on long-term durability testing, aiming to provide data on how many folds the device can withstand before failing, comparing it to Samsung's Galaxy Z Fold 8.

Why it matters

The early durability issues of the iPhone Duo could impact consumer confidence in Apple's first foldable device and its position in the competitive foldable market. If the hinge cracks are widespread, it could lead to significant repair costs and potential recalls. Conversely, if the issue is limited to a small subset of units, it may not significantly affect the device's long-term success. The durability tests by CNET and JerryRigEverything will provide crucial data on the device's lifespan and reliability, influencing future purchasing decisions and Apple's future foldable designs.

What to watch

CNET will continue its folding tests and share status updates and comparisons with the Galaxy Z Fold 8. Apple may issue a public statement or recall if the failure rate proves widespread. Consumers with defective units should contact Apple for replacements, as the issue is covered by the one-year warranty and 14-day return window. Further durability tests and real-world usage data will determine if the hinge cracks are a systemic issue or a minor defect.
