Apple has announced the iPhone Duo, a new foldable device featuring two displays and a titanium frame. The inner display measures 7.6 inches, 50% larger than the iPhone 18 Pro, while the outer display is 5.4 inches. The device uses a custom hinge with over 100 components, and a nano-texture finish to reduce glare and crease visibility.

It includes a 48MP Fusion main camera and a 12MP Center Stage front camera. Software features include adaptive multitasking and a new Standby mode. The iPhone Duo supports Apple Pencil on both displays and offers IP68 water resistance.
