iPhone Duo review: Apple's foldable phone tested - screen, camera, price, and features

Apple has unveiled the iPhone Duo, its first foldable smartphone, which was tested by reporters at the company's Cupertino headquarters. The device features a 7.6-inch screen, uses the A20 Pro chip, and combines iPhone and iPad capabilities. The Duo's nano-texture display nearly eliminates the visible crease common in foldables, and its iOS 27 software adapts apps seamlessly when opening, closing, or rotating the device. It offers a 50% larger internal screen than the iPhone 18 Pro Max, supports multitasking, and includes a comfortable external keyboard. The camera system includes 48-megapixel sensors with 2x optical zoom, though it lacks the Pro models' variable aperture. Pre-orders begin October 16, with sales starting October 23, priced from R$ 21,999 to R$ 30,999 depending on storage (256 GB to 2 TB).
