Smartphone Platform Leader

According to Statista Android is the undisputed smartphone platform leader. Of course, a single identified platform does not of itself identify which of the Android OS versions is used more than any other. Wikipedia Android version history states Android Lollipop 5.0-5.1 ( https://en.wikipedia.org/wiki/Android_version_history ) is the single most widely used Android version.
