Apple's first foldable iPhone, expected later this year, is rumored to feature a 7.8-inch inner display, a 5.5-inch outer screen, Touch ID in the side button, dual rear cameras, and a nearly crease-free foldable design, with software potentially benefiting from the iPad app ecosystem. Leaked dummy units suggest a compact passport-style form factor, and Apple may launch it in just one or two colors, likely prioritizing build quality and hinge design as its key differentiators.
