Google is expected to take the wraps off Android 4.4 KitKat soon, with reports pegging an unveil as early as 15 October. To hold us over, ZDnet has published a large gallery showing several design changes and features Android 4.4 will encompass. 

The build ZDnet got its hands on looks to be an early one, with mentions of Key Lime Pie instead of KitKat - the name introduced by Android head Sundar Pichai in early September. Nonetheless, the features shown in the screenshots gel with what we've heard and seen before

Most notably, Google has cleaned up its act in several aspects of design. The main homescreen will be clean when it is first booted, with just a camera and phone icon present at the bottom and a Google search bar at the top. There is also more of an emphasis on battery and power management, new icons, and the user interface of several built-in apps improved with design that makes more sense.  

Also shown is integrated NFC payments within Android 4.4 KitKat, if the "Tap to Pay" mode in the settings is anything to go by. It's not enabled in the leaked build, but looks enticing nonetheless.

Have a gander at the full gallery below, courtesy of ZDnet. Note that in most screenshots, Jelly Bean is shown on the left, with KitKat highlighted on the right so you can see changes.
