Unfolded iPhone Duo lets you preview documents in a two-page layout
The iPhone Duo’s Quick Look feature appears to have a two-page layout option when the foldable is held in its open book orientation, based on a new discovery from the PDFU code explorer.
A video clip shared on X shows an Apple Style Guide document previewed on 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 sharing controls on the right side.
The layout would make Quick Look the final feature to take advantage of the Duo’s large-format display. Apple has already detailed how iOS 27 adapts the device’s interfaces, including angle-aware layouts and side-by-side multitasking.
