Various reports have detailed several Android 4.4.3 KitKat sightings and suggested an update was imminent, but it looks like Google is not quite ready to release it. Android Police says that it has learned from several reliable sources that an Android 4.4.3 build has been rolled out to 1% of Googlers outside of the Android team for internal testing, or “dogfooding,” which means the final release isn’t expected for a “number of weeks” – unfortunately, an actual release date isn’t available yet.
The update, known internally as KitKat MR2 (following KitKat MR1 which consisted of Android 4.4.1 and Android 4.4.2) currently works only on Nexus devices including the Nexus 4, Nexus 5, two-Nexus 7 generations and Nexus 10, with the Moto X and Google Play Edition devices supposed to also get it soon.
Google apparently also said that Android 4.4.3 contains only “critical security and stability,” which is what a previous report from Android Police said, revealing a changelog of bug fixes in the process. For what it’s worth, KitKat MR2 has not been leaked yet, so it’s not available for testing outside of Google.
Google is also reportedly working on some major new Android features, known as “Project Hera.” It’s not clear when the next major Android OS update will be released, with an older report suggesting the company would launch Android 4.5 this summer.
