Apple’s OS 27 betas have added fresh weight to the long-running rumors around a folding iPhone, and the clues now go beyond normal software changes. The expected device, often referred to as the iPhone Ultra, appears to be linked with new code, flexible app layouts, and wider landscape support across Apple’s own apps.
The biggest clue sits inside the iOS 27 code, where references to foldState and angleDegrees suggest Apple is preparing software support for a device with a folding display.
These values would help apps understand whether a device is open, partly folded, or positioned at a certain angle, which makes sense for a book-style foldable iPhone with a new screen shape.
iPhone Mirroring Now Looks More Flexible
Another major hint comes from iPhone Mirroring on macOS 27, which now supports a freely resizable window instead of only fixed size options. This matters because Apple’s own apps can now adjust their layouts when the mirrored iPhone window becomes wider, which points to stronger app adaptability across different display shapes.
For a normal iPhone, this change feels useful, but for a folding iPhone, it feels necessary. A foldable iPhone Ultra would need apps that can shift between narrow phone layouts and wider tablet-like layouts without breaking the user experience.
More Apple Apps Support Landscape Mode
iOS 27 also brings landscape support to more Apple apps, including Find My, Fitness, Health, Home, Music, Podcasts, Reminders, Shortcuts, Watch, Weather, Voice Memos, and Apple TV Remote. Apple has also made Dynamic Island and Live Activities work better in landscape view, which adds another strong sign that the company expects users to spend more time in wider layouts.
Some apps still have partial landscape support, but the direction looks clear. Apple is preparing iOS for screens that do not behave like regular iPhone displays, and the OS 27 betas strongly suggest that the folding iPhone Ultra is getting closer.
