Hello, I'm an expert in the field of technology and mobile operating systems. Let's dive into the topic of Android 4.4 KitKat.

Android 4.4 KitKat is a version of the Android mobile operating system developed by Google, released in October 2013. It is the 16th version of the Android OS, and its codename during development was "Key Lime Pie," which was later changed to "KitKat" in a partnership with the chocolate company, Hershey's, which produces the Kit Kat candy bar.

Key features of Android 4.4 KitKat include:

1. Performance Improvements: It was designed to run smoothly on devices with as little as 512MB of RAM, which was a significant improvement for entry-level smartphones at the time.

2. New UI: KitKat introduced a new, more streamlined user interface with a focus on simplicity and ease of use.

3. Google Now Integration: Google Now became accessible directly from the home screen for a more seamless integration of information and services.

4. Cloud Printing: KitKat added support for cloud printing, allowing users to print documents from their devices to any cloud-ready printer.

5. Emphasis on Multiple Users: It introduced better support for multiple users on tablets, allowing each user to have their own space with apps and settings.

6. Fullscreen Immersive Mode: Apps could opt for an immersive fullscreen mode, hiding the status and navigation bars for a more distraction-free experience.
