Google just made available the Android 4.4 KitKat Quick Start Guide to help familiarize users with all the changes and updated and new features in the latest version of their mobile OS. The guide that you can see above and download below in PDF format is chock full of details about all of Android 4.4's new features. The guide consists of six chapters including Welcome to Android, Essentials, Use the keyboard, Try some apps, Settings and Accessibility. The 'beefiest' part of the guide is in 'Essentials' where you'll get walked through how to use everything from Google Now, Voice commands, Notifications and Settings, Android Beam, Tap to Pay, Printing, Chromecast and more. There's also special 'Nexus 5 tips' that point out particular differences or features that are available on the Nexus 5 but perhaps not other Nexus devices. Definitely worth downloading for every Nexus 5 owner or anyone with older devices that plan on upgrading to Android 4.4 KitKat.
