Apple is under scrutiny over the build quality of its first foldable smartphone, the iPhone Duo, following reports of inner display cracks and allegations of production shortcuts. The device was intended to establish a new benchmark for durability in a segment plagued by persistent screen damage. However, early user feedback and internal accounts indicate the company may have prioritized production speed over thorough quality checks.
The issue involves a rising number of iPhone Duo units developing cracks in the inner display—the screen that unfolds when the phone is opened. While Apple has confirmed the problem and directed affected customers to request replacements, the company has not released specific numbers. The scale remains limited but has drawn attention.
A report by Jiemian News adds depth to the controversy. An anonymous Foxconn worker claims Apple loosened quality control measures to rush production before the holiday season. The account suggests some components were substituted during assembly, though inspection protocols were not adjusted. The report lacks independent verification, and Apple has not addressed the specifics.
The timing is critical. Apple reportedly plans to deliver 7.5 million iPhone Duo units by the end of 2026, a target that could strain manufacturing processes. For a brand synonymous with rigorous hardware standards, even the suggestion of compromised quality checks stands out.
Hinge design raises durability doubts
The hinge mechanism has emerged as another concern. A teardown by YouTube analyst CuriousHagi pinpointed a potential vulnerability: a thinner link-type hinge component near the inner display. This design choice raises questions about whether repeated folding could exert stress on the screen above. Some users report hearing a cracking noise before visible damage appears, though the exact cause remains under investigation.
Foldable phones depend on precise coordination between the hinge, support structures, and flexible display layers to avoid damage. Identifying a single root cause is difficult, especially with early production models. The iPhone Duo is not the first foldable device to encounter durability problems; competitors including Samsung and Google have faced similar issues. Yet Apple’s entry carries greater weight due to its reputation for engineering precision.
Software struggles with foldable display
Software performance has also faced criticism. Early reviews noted a cluttered interface, particularly in apps like Safari, which failed to adapt smoothly to the larger inner display. Apple has since acknowledged the flaws and committed to fixes through software updates. Still, the initial impression, a device struggling to leverage its most innovative feature, contrasts sharply with the refined experience customers expect from the brand.
The broader issue is whether these early challenges will undermine Apple’s long-term foldable strategy. The company has confirmed replacements for affected devices and stated it is working on solutions. Given its resources, it has the capacity to address both hardware and software refinements. However, the iPhone Duo’s success hinges on whether subsequent models demonstrate improved durability and whether Apple upholds its usual quality control.
For now, the device remains in development. While inner display cracks and hinge concerns are documented, they do not yet indicate a widespread failure. Yet in an industry where buyer trust is fragile, even isolated incidents can have lasting effects. Apple’s ability to resolve these issues efficiently and transparently will define whether the iPhone Duo fulfills its role as a standard-setter for foldable technology.
