More iPhone Duo features surface thanks to eagle-eyed reviewers

Apple's iPhone Duo, unveiled on September 9, combines the functionality of both a standard iPhone and an iPad mini. Despite its debut being delayed to October 23, early reviewers have already discovered some unique features of the foldable device. For instance, the iPhone Duo supports Edge Light for FaceTime calls, a feature previously found only in Macs with Apple Silicon chips.

Additionally, the device includes a horizontal version of Reachability, an Accessibility feature that brings top interface elements closer to the bottom of the screen. The iPhone Duo will also soon feature Smart Take, a capability that automatically takes a photo when everyone involved is ready, eliminating the need for timers and manual button presses.

Lastly, the upcoming iOS 27.2 update will bring Apple Pencil support to the iPhone Duo, though it is currently only available with the release candidate build. While the iPhone Duo boasts a variety of exclusive features, such as these hardware and software enhancements, it remains to be seen whether third-party applications will eventually support the device's display aspect ratios.
