Android 4.4.3 KitKat has been in the rumor mill for a few months already and it looks like this update is now very close to becoming official. Although Google mentioned it before without giving away any details, now T-Mobile has just announced the Android 4.4.3 KitKat update for Nexus 4, Nexus 5 and Nexus 7 2013.
Back in April Sprint removed the info about Android 4.4.3 KitKat from its support pages shortly after it went online. Now T-Mobile will not have do that, since this update is already listed on Google's own "Factory Images for Nexus Devices" page. Android 4.4.3 code is now also available via the Android Open Source Project (AOSP).
The list of bugs that update 4.4.3 is expected to address includes the Nexus 5 camera issues, various battery draining problems, as well as Bluetooth and data connection issues. We will get back to this topic as soon as Google unveils the official change log, probably later this week.
