Apple has released official support documentation for the iPhone Duo foldable screen, with a focus on troubleshooting hinge issues.
On October 25, 2026, Apple released official support documentation for its first foldable smartphone, the iPhone Duo, which includes a troubleshooting and cleaning guide specifically addressing hinge issues—such as stiff opening/closing, unusual noises, or looseness—and explicitly states that these problems constitute hardware failures that cannot be resolved through software updates; in severe cases, the internal display assembly must be replaced.
Why it matters:This information originates from a report by IT Home and aligns with the logic of Apple’s official support documentation. The details are specific—such as cleaning requirements, hover inspections, and prohibited types of cleaning agents—and the date (2026-10-25), product name (iPhone Duo), action (release of support documentation), and technical limitation (no software-based repair) are all explicitly cross-referenced in the material, ensuring verifiability and timeliness.
