A key feature of the updated Android OS is its improved memory capabilities.
"With KitKat, we've slimmed down Android's memory footprint by doing things like removing unnecessary background services and reducing the memory consumption of features that you use all the time," the company said in a statement.
"RAM [or memory] is one of the most expensive parts of a phone, and now Android can run comfortably on the 512MB of RAM devices that are popular in much of the world, bringing the latest goodies in Android 4.4 within reach for the next billion smartphone users."
Google is known for naming its mobile software after different types of desserts. Past names have included Cupcake, Donut, Honeycomb, Jelly Bean and now KitKat. Earlier this year the tech giant and Nestle struck a marketing deal naming the new software after the candy bar.
