Apple Unveils $1,999 iPhone Duo With Touch ID and New Camera Tools
The company's first folding device arrives with a fingerprint sensor, software adjustments, and specific repair costs for its unique display.

Apple released the iPhone Duo, its first folding smartphone, on October 23, 2026. Priced at $1,999, the device marks a seven-year gap since Samsung introduced the Galaxy Fold. The company refined the hardware over that period, resulting in a device that Wired described as a "pretty dang good foldable." The launch brings a new form factor to the market with a 5.4-inch outer screen and a 7.6-inch inner display.
The most immediate challenge for buyers involves software compatibility. Many applications have not been optimized for the new screen dimensions. While Apple's native apps function correctly, numerous third-party titles display as narrow strips with thick black bars on the sides. Slack, Instagram, DoorDash, and WhatsApp have received updates for iOS 27.1, but some still show broken interface elements. Apple moved navigation elements to the right rail instead of the bottom center. Since the phone is back-ordered for several weeks, developers may finalize updates before many customers receive their units.
The Duo abandons Face ID in favor of Touch ID, with the sensor located on the right side of the device. This is the first time a flagship iPhone has used fingerprint authentication since the iPhone SE, iPads, and MacBooks retained the feature. The thinness of the phone likely necessitated the change. The Dynamic Island remains but relocates to the top-right edge near the outer selfie camera. It appears in the same corner on the inner display during live activities.
Accessories require adjustment for the new shape. The phone supports MagSafe, but it tips to one side when attached to a car dock or tripod while unfolded due to uneven weight distribution. Third-party makers may need to add anti-rotation magnets to existing gear. Magnetic wallets attach securely but extend past the bottom edge because the Duo is shorter than other iPhones. Apple has not offered an official fix for this issue.
Photography features include the ability to take selfies using the superior rear cameras while previewing the image on the outer screen. Users can launch the camera, flip the phone, and use a "Slide to show camera" control to bring the full camera app to the outer display. This includes modes and Photographic Styles and disables the inner screen to prevent accidental touches. The "Duo Preview" feature allows the subject to see the viewfinder. "Kids Cue" plays Snoopy animations on the outer screen to attract a child's attention.
Multitasking allows users to drag an app from the bottom to either side of the inner screen to run two applications side by side. Tapping the middle bar once makes it glow white and locks the two apps as a pair. This pair is accessible from the Recent apps menu but cannot be saved as a single icon.
The inner display features a matte nano-texture finish that Apple calls an "integral" component. The company's support page warns users not to attempt to remove it, as doing so could void the warranty. Apple does not address third-party screen protectors, which might hurt display performance. A damaged finish costs $19 to replace at an Apple Store or authorized provider, or $49 out of warranty. A cracked inner display costs $999 without AppleCare+.
Several conveniences are scheduled for future software updates. The keyboard can currently be split to ease typing on the wide inner display. A later update this year will add Reachability, shifting apps to the left or right instead of pulling them down. Another update will add support for the USB-C Apple Pencil. Only that specific model is supported, and the phone has no place to store the stylus.
