Priced starting at $1,999, Apple’s inaugural foldable smartphone, the iPhone Duo, has encountered initial setbacks. Following its release, users across various regions have reported screen damage concentrated in the folding mechanism area. Some users observed screen cracks forming along the fold line within just six hours of unboxing the device and subjecting it to fewer than 20 folds. Meanwhile, others reported display malfunctions within a single day of use, or even before completing the initial setup process.

Durability assessments have highlighted additional concerns. The hinge design appears susceptible to dust ingress, and following stress tests involving repeated bending, the inner screen exhibited bright lines in the crease area and became unresponsive to touch input. Moreover, the flexible inner screen proved vulnerable to scratches at a mere Mohs hardness level of 2.

These issues have prompted some pre-order customers to reconsider their purchases, with cancellations or delivery delays on the horizon. Post-sales challenges further complicate matters, including pre-authorization requirements for repairs and ambiguous timelines for replacement unit deliveries. While the industry has yet to confirm widespread systemic flaws, the fundamental durability of this premium flagship device—marketed as a pioneer in foldable technology—has ignited considerable debate.
