Overview
- Apple began selling the iPhone Duo on Friday, October 23, with some stores offering reserved pickup while online orders show shipping dates pushed into early 2027.
- Supply is tight because first‑batch production was small and yields are low, with industry reports citing roughly 2 million initial units and whole‑unit yields a little over 60 percent.
- Apple’s new foldable uses a book‑style inner fold (5.4‑inch outer, 7.6‑inch inner), drops Face ID for side‑button Touch ID, supports eSIM only, and relies on a complex hinge made of more than 100 parts that has constrained assembly.
- Early hands‑on coverage praises hinge feel after mechanical testing of about 32,640 folds but criticizes the under‑display front camera for poor image quality and notes initial app layout problems that developers are patching.
- Apple launched developer tools and a 'Made for iPhone Duo' App Store badge and major apps such as QQ, WeChat, maps and productivity apps have released Duo optimizations to use the larger inner display and split‑screen modes.
