Google on Monday began rolling out its long-awaited Android 7.0 Nougat release to Nexus smartphones and tablets. The new operating system became available as a beta release, known only as "Android N," earlier this year. The experiences of developers and other users led to more than 250 new features, including improved multitasking, stronger battery life and tighter security features, noted Sameer Samat, vice president of product development. The new OS provides quick access to settings, so important features are readily available when needed.
