Recent durability testing indicates that the device referred to as the iPhone Duo is facing significant physical endurance challenges, performing similarly to other first-generation foldable smartphones.

The results highlight the persistent engineering hurdles tied to folding displays and complex hinge mechanisms. Despite high expectations for Apple's potential expansion into the category, the hardware reportedly showed vulnerabilities typical of early foldable efforts.

While the broader foldable segment continues to evolve, achieving long-term structural resilience remains a key obstacle for any company entering the space with a new form factor.
