Android KitKat

Android KitKat is the codename for the eleventh version of the Androidmobile operating system, representing release version 4.4. Unveiled on September 3, 2013, KitKat focused primarily on optimizing the operating system (running on as little as 512 MB of RAM; Project Svelte) for improved performance on entry-level devices with limited resources. It is the last version of Android to use the "Holo" interface. On July 24, 2023, Google announced that Google Play Services would no longer support KitKat in August of that year. The first phone with Android KitKat was the Nexus 5.

As of March 2026, 0.06% of Android devices run KitKat.
