Subsequent to making the official factory images available to the public last night, Google has today started pushing out the much-anticipated Android 4.4.3 KitKat update (build KTU84L) to all Nexus devices located in the United States.

Unfortunately, this latest build of the open-source operating system doesn’t bring any major improvements. It’s more of a maintenance update intended to round off some of the rough edges present in Android 4.4.2. The full changelog for the 74MB, courtesy of the good folks over at Android Beat, can be seen below: 

• A tweaked Dialer app with a colored Action bar.
• People’s app now placeholder images are now similar to that one used by Gmail.
• Fix for the hissing sound while recording videos on the Nexus 5.
• Fix for LTE connection dropping bug.
• Wi-Fi improvements.
• Microphone and earphone related changes.
• Camera, Bluetooth and other system related bug-fixes.

If you own a Nexus 4, 5, 7 or 10 and haven’t yet received the OTA update, you can head into “Settings,” then “About Device,” and select “Check for Updates” to manually scan for the upgrade. Alternatively, you can wait until you receive a push notification prompting you to download and install the update.
