iPhone Duo Trade-offs Impact FaceID and Camera Performance
Apple’s iPhone Duo foldable smartphone omits FaceID and the Camera Control button found on traditional iPhone models, Engadget reported. The device replaces facial recognition with a fingerprint sensor integrated into the power button and removes the periscope telephoto lens and LiDAR scanner available on the iPhone 18 Pro.
TouchID replaces FaceID for authentication
The iPhone Duo does not include the FaceID array required for facial recognition. Users must authenticate using passwords or a fingerprint sensor located in the power button. This implementation mirrors the hardware design used by Samsung and other foldable device manufacturers. While this provides a tactile alternative for users who prefer TouchID, it removes the instant unlocking and app-logging experience provided by Apple's facial scanning technology.
Camera hardware lacks Pro features
The iPhone Duo features three separate camera arrays, but each is downgraded compared to the iPhone 18 Pro. The rear platter contains 48-megapixel wide and ultrawide modules but lacks the periscope telephoto lens, LiDAR scanner for nighttime photography, and the mechanical aperture found on the Pro model.
Front-facing hardware also sees a reduction in specifications. The cover display uses a 12-megapixel selfie camera, while the iPhone 18 Pro uses an 18-megapixel sensor. The inner folding display features an under-display FaceTime camera, though Apple has not disclosed the megapixel count for this specific sensor.
Software restrictions limit creative tools
Apple has excluded several professional software features from the Duo. The device does not support Pro Controls for adjusting shutter speed and aperture, nor does it support ProRAW shots for professional editing. Spatial photo and video capabilities are also absent, limiting utility for Vision Pro owners. These omissions, combined with the lack of a Camera Control button and true multi-window multitasking, position the Duo as a media consumption device rather than a professional creative tool.
