The recent Android OS from Google is Android KitKat 4.4. KitKat 4.4 was built with a more maximized performance. It is more receptive and quicker -- however, it does not have clear direction and distinct features. Created with a refined platform, Android KitKat 4.4 offers a more enhanced performance with advanced features. Memory usage is augmented with a seemingly Moto X-like element, where an always-listening-to-Google method allows quick searches.

Activate it by saying "Ok Google," and you can get directions, send a text or play music. With the optimized memory and augmented touchscreen, you can browse the web while listening to a song. When the gadget is locked, you get a stunning full-screen movie art and album while listening to a song. Play and pause are available as well. It features an immersive mode where everything is concealed automatically so you get to see only the items that you want. Get back to the navigation buttons and status bar by swiping the screen's edge.

Your contacts are saved depending on the frequency of the people you talk to. Searching for businesses and places near your area is allowed, as well as for contacts or for those who are listed in your Google Apps domain. It features new colorful Emoji accessible on Google Keyword. Printing documents, photos or web pages is allowed using your tablet or phone. You can print to HP ePrint printers and other printers with the Google Play Store apps by connecting your device to Google Cloud Print.
