Google Android 4.4 - KitKat OS new features
Features of this new Mobile OS are noted in following links
QUOTE: Google has revealed the features contained within the latest version of Android operating system, 4.4 or KitKat, which it first announced in September. There's nothing mind-blowing, but the features are helpful — and hint at devices to come. KitKat relies more than ever on behind-the-scenes Google services to enhance everyday tasks. For instance, a new caller ID will check business listings for an unknown number so you know it's the vet or hardware store and not a telemarketer. And searching contacts will bring up nearby places, not just people on your phone. A new "immersive" mode lets apps and games take over the whole screen — no buttons or status bar to be seen. And an improved file-finding tool minimizes switching between apps when you're looking to attach or modify a recently used or downloaded image or document.
