Apple’s iPhone Duo is getting a book-style document viewer that displays two pages side by side when the foldable is fully opened, taking advantage of its larger 7.6-inch inner screen.
A new hands-on video shows Apple’s Quick Look viewer displaying consecutive pages of a document across the unfolded screen, much like reading an open book.
Search, markup, and sharing controls sit along the right edge, leaving most of the display available for the document itself.
Quick Look adapts to how you hold the iPhone Duo
The two-page layout responds to the Duo’s open-book position, allowing the document viewer to change its presentation based on how the device is held.
On a conventional iPhone, reading a PDF usually means viewing one page at a time and scrolling or swiping through the document.
The Duo’s wider display can show facing pages together, making it easier to review documents, compare adjacent pages, or follow layouts designed for print.
It’s another example of how Apple is adapting iOS 27 to the foldable screen. The Duo already supports angle-aware interfaces and side-by-side multitasking, allowing apps to change their layouts depending on how the phone is opened.
The main concern is readability. Squeezing two full pages onto a 7.6-inch screen doesn’t leave much room for text, especially with PDFs formatted for standard paper sizes.
This setup may be better suited to skimming documents or navigating pages than to reading dense text for extended periods.
iPhone Duo launches October 23
The iPhone Duo features a 5.4-inch outer display and a 7.6-inch foldable inner screen, giving users a more expansive workspace when opened.
Preorders begin Friday, October 16, at 5 a.m. Pacific, with availability starting October 23.
The new Quick Look layout offers another glimpse of how Apple is putting that extra screen space to work, bringing a familiar two-page reading experience to its first foldable iPhone.
