Overview
- The iPhone Duo has reached heavy consumer demand and rapid sellouts but reviewers and teardown testers reported early problems, including cracks in the inner foldable display near the hinge and dust ingress.
- Apple has acknowledged a "small number" of inner‑display cracks and is offering replacements to some customers while investigators and independent testers probe hinge support, panel yields, and assembly quality.
- Reviewers flagged key feature gaps on the shipping Duo, specifically the absence of Face ID and a telephoto lens, muted colors on the main foldable screen linked to a nano‑texture layer, and a heavier build than rival foldables.
- The device’s software and app support limit the practical value of the larger screen because many third‑party apps are not optimized and iOS multitasking currently restricts split‑view to two apps, reducing productivity gains.
- Industry coverage says Apple is likely to iterate quickly; one report states the company is testing an under‑display Face ID variant, and observers warn that supply constraints, costly out‑of‑warranty repairs, and competitor advances will shape whether a Duo 2 is rushed and how the product fares long term.
