Apple has introduced the iPhone Duo, its first foldable display device, along with details on how third-party apps will adapt to the larger screen. In a developer-focused tech talk video, Apple outlined the three compatibility modes for iOS apps on iPhone Duo. The first mode is the default compatibility mode, which apps will use until updated for iOS 27.0.
This mode utilizes a safe area with a black background around the app. Apps updated for iOS 27 benefit from a more extensive display in the default mode, though some blank space remains. The third mode, full compatibility mode, aims to utilize the entire iPhone Duo display when iOS 27.1 arrives in October. Apple and third-party developers are encouraged to create apps optimized for the new iPhone Duo display to provide the best user experience.
