Apple’s upcoming iPhone Duo appears to gain a new Quick Look viewing option that shows documents across both halves in an “open-book” orientation. Multiple outlets report new findings from code explorer “pdfu,” who points to iOS 27 beta changes that introduce a two-page layout for Quick Look.
The reported behavior displays consecutive pages side by side, resembling a spread, when the foldable is unfolded. One video clip shared publicly shows an Apple Style Guide document previewed across both halves, with Quick Look controls—such as search, markup, and share—appearing in the interface. Outlets also note that the two-page preview aligns with iOS 27’s broader approach to adapting layouts for the Duo, including wider and angle-aware presentation.
While the reports are based on beta code and leaked previews rather than an independently verified official specification in the articles, they collectively describe the same core change: Quick Look can present certain documents in a two-page format in the open-book position.
