The iPhone Duo is getting Apple Pencil support with iOS 27.2, which is expected to reach the public next week.
Creative Strategies analyst Max Weinbach flagged the change. The USB-C version of the Apple Pencil will let owners draw, annotate and scroll in supported apps, on both the inner and outer displays. Apple has not detailed which apps count as supported, or whether any other Pencil models will work.
The Pencil has been an iPad accessory for years, while the iPhone has stayed finger-only. Tying Duo support to the USB-C Pencil means anyone who already owns one needs nothing new. That keeps the cost of trying it close to zero for existing iPad users.
The outer display is the more interesting detail. A cover screen is small, and scrolling on it with a stylus is not an obvious use case. Including it suggests Apple is treating the Pencil as a general input tool on this phone, not only a drawing instrument.
Samsung has a long head start on the idea. Its S Pen defined the Galaxy Note line and later moved to other large-screen phones, so a stylus on a phone is not new, only new to Apple.
The open question is software. The Pencil became useful on the iPad largely because note-taking and drawing apps built around it. Whether developers do the same for a phone, and how much of the system Apple opens to it, will decide if this is a feature people use or one they try once.
