Apple has unveiled a new foldable smartphone called the iPhone Duo, featuring a dual-screen design and a highly engineered hinge. The device folds down to a 5.4-inch outer screen, retaining 90 percent of the active area from the iPhone 18 Pro. The inner screen measures 7.6 inches, offering a larger display for multimedia and multitasking. The hinge, composed of 100 individual components, allows for smooth and durable folding. This marks Apple's first attempt at a premium foldable phone priced over $2,000. The iPhone Duo is expected to compete with other high-end foldables from Samsung and Huawei. The design aims to combine portability with a large display, catering to users who value both form and function. The release date and pricing details have not yet been announced.
