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