A new finding by code explorer pdfu suggests the iPhone Duo’s Quick Look feature supports a two-page layout when the foldable is held in its open-book orientation. A video clip shared on X shows an Apple Style Guide document previewed across both halves of the unfolded iPhone, with consecutive pages displayed side by side like a spread. When navigating the document, the Quick Look interface displays search, markup and share controls along the right-hand side.

The spread-style layout would make Quick Look the latest feature to take advantage of the Duo’s wide-format display. Apple has already detailed how iOS 27 adapts interfaces for the device, including angle-aware layouts and side-by-side multitasking.
pdfu posted the clip on X on October 6, 2026.
Pre-orders for iPhone Duo open at 5 a.m. Pacific Time on Friday, October 16, with availability beginning Friday, October 23.
