The latest iOS update introduces Apple Pencil compatibility for the iPhone Duo, marking a significant enhancement for users. Alongside this, the update features an 'Edge Light' function designed to illuminate the user's face during video calls. Apple had previously announced that the iPhone Duo would support the Apple Pencil 'later this year,' and this update fulfills that promise. The device's first foldable design comes with revamped iOS 27 controls tailored for its dual-screen setup, with a 7.6-inch inner display and a 5.4-inch outer screen. Major apps like Netflix, Prime Video, and Microsoft Outlook already support the Duo's expanded screen space, though some still require further optimization. The iOS 27.2 update also enhances Siri AI capabilities, allowing it to suggest actions in Messages and supporting additional languages such as French, Japanese, and Spanish.
