Apple's unannounced iOS 27 and watchOS 27 features include a customizable camera app, Siri Extensions, and a new Apple Watch face

Apple has three unannounced features for iOS 27 and watchOS 27: customizable camera app, Siri Extensions for third-party AI chatbots, and a new Apple Watch Modular watch face. These features are in internal builds and have been tested by employees. The customizable camera app allows users to rearrange controls, Siri Extensions enable integration with other AI chatbots, and the new watch face offers a simplified version of the Modular Ultra. It is speculated that Apple may hold back these features for future hardware releases or strategic marketing reasons, with potential availability in later software updates or alongside new device launches.
