The Apple iPhone Duo features a foldable display with a nano-texture layer to reduce crease visibility

The Apple iPhone Duo is a foldable smartphone that utilizes a specialized nano-texture layer over its display to minimize the visibility of the central crease and eliminate screen reflections. The device features a dual 48MP fusion camera system on the exterior and an under-display camera on the interior. It supports Touch ID via a side-mounted sensor rather than Face ID. The interface is optimized for the foldable form factor, allowing users to run two apps side-by-side in split-screen mode, with controls automatically shifting to the edges of the display. The device is MagSafe-compatible, though its compact folded size limits the use of some larger accessories. It supports 25W wireless charging and can function in a "tent mode" for media consumption or as a clock display. The top cover layer is replaceable at Apple Stores, which helps avoid the need for a full display replacement. The device is expected to support the Apple Pencil USB-C, with an update scheduled for release before the end of October.
