Announced last year in May, the Sony Xperia X and Xperia X Compact smartphones came with Google’s Android 6.0.1 (Marshmallow) mobile operating system, and they were later updated to Android 7.0 (Nougat), a major update that added multi-window support, longer battery life, and Messaging improvements. For the Xperia X series, the Android 7.0 (Nougat) update also implemented a more personal and smarter Xperia home screen featuring Google Now integration. Additionally, the Camera app was enhanced with all-new manual focus and shutter speed controls, and some important issues have been resolved.
