Launched at Google's I/O Conference in May, Android Nougat, apart from featuring in upcoming Nexus flagships, will also power existing ones like Google's Nexus 5X and 6P, Motorola Nexus 6, Nexus 9G, Nexus Player, Google Pixel C and General Mobile 4G running Android One.
Even though the final version of Android Nougat is yet to be released, its beta version is available to be downloaded on existing devices. While Android N has undoubtedly brought in a number of new features, security updates and battery saving functions compared to Android 6.0 Marshmallow, you will be able to try out these features and provide feedback to Google based on your experiences. Once you download the beta version, you can try out a new app carousel which will put recently used apps in a list, use two screens at a time, try out the 'Clear All' button, respond to notifications without opening apps as well as try out the new Unicode 9 emoji support.
You can download the beta version of Android Nougat at https://g.co/androidbeta but you will need to sign up first. If you would like to know more about Android N before installing it, you can read about it on the Google developer website.
Once you download the beta version, you will also be able to experience a new graphics API named Vulcan. Vulcan lets apps install 75 per cent faster in phones running Android N compared to those that run older operating systems, including Marshmallow. Android Nougat also includes file-based encryption, media-hardening framework, new battery saving features and probably a lot of good-looking wallpapers.
