A New Chapter for iOS

With [the iPhone Duo is arriving in October](https://www.engadget.com/2254389/iphone-duo-hands-on-apple-s-most-exciting-device-in-a-decade/), Apple is introducing a foldable form factor that requires more than just standard iOS. While the core operating system remains familiar, the software has been fundamentally overhauled to suit a device that changes shape. According to reporting from [Engadget](https://www.engadget.com/2261250/iphone-duo-vs-standard-software-differences/), these adjustments allow the phone to function in several distinct modes that are impossible on a traditional slab smartphone.

Enhanced Multitasking Capabilities

For years, iOS users have managed apps through background suspension, but [it's never been iPad-level multitasking](https://www.engadget.com/mobile/tablets/ipados-26-preview-a-long-awaited-multi-tasking-update-pays-off-so-far-172522054.html). The new device changes this paradigm entirely, as the [iPhone Duo is the first iPhone with iPad-inspired multitasking](https://www.engadget.com/2254063/iphone-duos-interface-is-ipad-like-with-some-extra-tricks/).

While the interface does not replicate the full Stage Manager experience found on tablets, it allows users to run two applications simultaneously on the inner screen. The interface has been carefully optimized, enabling users to keep their Home Screen visible on one side while operating an app on the other. Furthermore, [Apple Pencil now works on the iPhone](https://www.engadget.com/2255122/use-apple-pencil-with-iphone-duo/), enhancing the utility of the larger display for productivity tasks.

Interface and Hinge Awareness

The status bar has undergone a significant visual redesign to accommodate the device’s physical profile. Rather than spanning the top of the display, the status bar is now positioned on the right side. This section integrates the Dock and Dynamic Island, while grouping signal, Wi-Fi, and battery indicators to maximize available screen real estate.

The software also features hinge awareness. When the device is partially folded, the OS detects the angle and repositions content. For example, in media playback, the app content shifts to the top half of the screen while input elements, such as the keyboard, occupy the bottom half. Additionally, the device can enter a "tent" mode, functioning as a table clock that automatically illuminates when an alarm sounds.

Exclusive Camera Features

The foldable form factor enables unique photographic capabilities not available on standard models. One notable addition is 'Smart Take,' which utilizes AI to trigger a shutter when the subject strikes a pose, eliminating the need for timers or button presses. Users can also utilize the external screen for live previews, making it easier to capture high-quality selfies with the primary rear camera system.

For parents, a new 'Kid Cue' mode displays a Snoopy animation on the external screen to help focus a child’s attention toward the lens. FaceTime has also been updated to support simultaneous front and rear camera views, simplifying group interactions. Despite these innovations, the device [lacks many of the camera features found on the iPhone 18 Pro](https://www.engadget.com/2254121/the-iphone-duo-lacks-variable-aperture-and-a-dedicated-telephoto-camera/), such as pro-grade manual controls and variable-aperture lenses, reflecting a deliberate design trade-off for the foldable category.
