Android

Android is a mobile operating system developed by Google. It is based on a modified version of the Linux kernel and other open source software, and is designed primarily for touchscreen mobile devices such as smartphones and tablets. Android has a large community of developers writing applications ("apps") that extend the functionality of the devices. Apps can be downloaded from third-party app stores or through online stores such as Google Play. Android has been the best-selling OS on tablets since 2013, and on smartphones it is dominant by any metric.
