The iPhone Duo is Apple’s first foldable smartphone, featuring a premium grade 5 titanium design that unfolds horizontally like a book. When closed, it offers a compact 5.4-inch outer display for quick daily tasks, and opening the device reveals an expansive 7.6-inch Super Retina XDR inner display ideal for multitasking and gaming. The internal display uses a specialized nano-texture finish to minimize glare and screen creases, while a hidden under-display camera provides an uninterrupted viewing surface. Powered by the advanced A20 Pro chip, this premium device runs on a reimagined iOS 27 tailored specifically to fluidly transition applications between its unique screens.
