In an effort to create a balance in the force, Google has dropped the Android 4.4.3 image for the Nexus 5, Nexus 7 2013 (excluding the LTE version at present), Nexus 7 2012, Nexus 4 and Nexus 10 on their downloads page. It's a 440-465MB download, and you'll need fastboot set up to install it. We've not yet seen any OTA updates, but we imagine they are coming if you'd rather wait. More details and download links after the break.
So far the only major change we're seeing is a visual refresh to the Phone app, bringing a card-based view for "Speed Dial" contacts along with a new accent color. The update is also expected to fix bugs relating to CPU usage and the Nexus 5 camera that were acknowledged by Google a couple months back.
