Overview
- Apple enabled Apple Pencil compatibility in the iOS 27.2 Release Candidate, with the public iOS 27.2 rollout expected Monday, October 26, so pre-order customers should get stylus support within days of receiving the Duo.
- Only the Apple Pencil (USB-C) model is supported by the iPhone Duo, so owners of older Pencil models must buy the USB-C version to use the feature.
- Analyst Max Weinbach confirmed on X that Apple Pencil functions in the iOS 27.2 RC, showing the feature works on both the Duo’s inner and outer displays in supported apps.
- Apple’s developer moves this month, including Xcode 27.1 RC and new App Store submission tools, prepared apps to handle the Duo’s folded and unfolded states ahead of the stylus launch.
- The addition of Pencil support sets the Duo apart in the foldable market where some competitors removed pen input, and it could boost the device’s appeal to users who want a phone-sized device for note-taking and markups.
