Hands-on with the iPhone Duo: Apple’s approach to the folding screen

Apple has officially entered the foldable smartphone market with the iPhone Duo, a device featuring a 5.4-inch external display and a 7.6-inch internal screen. The device distinguishes itself with a unique hinge design and a specialized nano-texture coating on the main display, which effectively hides the traditional folding crease by dispersing light. Powered by the new 2-nanometer A20 Pro chip, the iPhone Duo includes a redesigned iOS interface optimized for the dual-screen layout, featuring a dock on the right side for improved accessibility. Despite its complex construction, which includes multiple polymer and glass layers, the device maintains IP68 dust and water resistance. During initial testing, the transition between the cover and main displays proved seamless, and the matte finish provided a distinct tactile experience. While the 2x optical zoom may be modest for some, the overall engineering marks a significant milestone for Apple's hardware portfolio.
