Apple launches iPhone Duo, its first foldable phone with a 7.6-inch screen

Apple announced the iPhone Duo, its first foldable smartphone, on Wednesday, marking the biggest design change for the iPhone in nearly 20 years. The device starts at $1,999 and launches on October 23. The passport-sized Duo is the thinnest iPhone ever when unfolded, featuring a 7.6-inch inside screen, 80% larger than the iPhone 18 Pro's display. Its software adapts to folding positions, enabling features like split-screen apps, tent-mode bedside clock use, and simultaneous dual-camera FaceTime calls. Apple enters a market long dominated by Samsung, Huawei, and Motorola, though foldables remain a niche. The launch is critical for Apple, which faces pressure after the Vision Pro headset and iPhone Air underperformed, and the Duo's success may hinge on its tailored software experience.
