The iPhone Duo's Quick Look feature includes a two-page layout option when the foldable is held in open-book orientation, as discovered by code explorer pdfu. A video shared on X shows an Apple Style Guide document previewed across both screens, displaying consecutive pages side by side like a spread. Navigation controls for search, markup, and share appear along the right-hand side.
This layout leverages the Duo's wide-format display, following earlier iOS 27 adaptations such as angle-aware layouts and side-by-side multitasking. Pre-orders for the iPhone Duo open at 5 a.m. Pacific Time on Friday, October 16, with availability beginning Friday, October 23. The device was announced at Apple's 'Surprise and Shine' event on September 9, 2026, featuring two screens and a foldable inner display designed for a seamless open-to-closed transition.
Apple claims it is the thinnest iPhone ever made when fully unfolded.
