Apple iOS 27 Code Hints at a Foldable iPhone Ultra With a Wider, More iPad-Like Interface
Apple has officially introduced iOS 27, the next major software update for the iPhone, and early developer testing is already revealing some intriguing details. While the update is expected to roll out publicly in the fall, developers with compatible iPhone models have begun exploring the beta version and digging into its underlying code.
What they found appears to strengthen rumors that Apple is preparing a foldable iPhone, possibly called the iPhone Ultra.
Several references discovered inside iOS 27 point to hardware features that would make sense for a folding device. Terms such as “foldState” and “mechanicalAngleDegrees” suggest that the operating system can detect whether a hinge is open, closed, or positioned at a certain angle. This type of software behavior is commonly associated with foldable devices, where the interface needs to adjust depending on how the screen is being used.
Additional clues reportedly point to more advanced hardware support. The software appears to reference a second display, an additional glass cover, and extra ambient light sensors. These details suggest that Apple may be preparing iOS 27 to work with a device that has more than one screen area or a folding design with multiple display modes.
The most interesting part is that some of these changes may already be visible in the user interface. When an iPhone display is mirrored on a Mac, iOS 27 appears to support a wider layout than before. Instead of looking like a traditional narrow iPhone screen, the mirrored interface can expand into a broader two-column design that feels closer to an iPad experience.
That design choice could be a major hint at how Apple plans to handle a foldable iPhone display. A larger inner screen would need a more flexible interface, especially for multitasking, app navigation, and split-screen-style layouts. If the rumored iPhone Ultra opens like a book, a two-column iOS interface would make much better use of the available space.
Another possible clue comes from iOS 27’s new full-screen widgets. These widgets can display apps such as Music or Weather across an entire iPhone home screen. On a standard iPhone, that may feel like a bold visual upgrade. But on a foldable iPhone Ultra, these widgets could occupy only one half of the unfolded display, leaving room for another app, widget, or control panel on the other side.
Taken together, these software discoveries make the foldable iPhone rumors feel more realistic than ever. Apple has been expected to enter the foldable smartphone market for years, but the company has typically waited until it can deliver a more polished product rather than rushing into a new category.
If the iPhone Ultra is announced alongside the iPhone 18 Pro lineup in September, it could become one of Apple’s biggest hardware launches in years. A foldable iPhone with deep iOS 27 integration, a larger multitasking-friendly display, and Apple’s usual focus on premium build quality would likely attract major attention from iPhone users and the wider smartphone market.
For now, Apple has not confirmed any foldable iPhone plans. Still, the growing number of references inside iOS 27 suggests that the company may be laying the groundwork for a new form factor. Whether it launches this year or later, iOS 27 appears to be preparing the iPhone for a future beyond the traditional single-screen design.
