Google recently announced Android KitKat (version 4.4) with the Google Nexus 5 being the first smartphone that is powered by the mobile operating system. Android KitKat was designed to support backwards compatibility for over 1 billion older smartphones and tablets. By requiring less memory, Android KitKat can run on entry-level devices that have as little as 512MB of RAM.
Google Android head Sundar Pichai said that the goal for 2014 is to “reach the next billion people.” In emerging countries like Brazil, India, Russia, Indonesia, and Mexico, Android’s business is tripling every year. In some of those countries, several manufacturers have been selling Android phones that are powered by the two-years-old Android Gingerbread (version 2.3) operating system. Android KitKat is intended to prevent older software from being sold in those emerging countries.
