Google I/O is coming up quickly, but in the meantime, it’s mobile OS is seeing an upgrade to 4.4.3. It’s not going to knock anyone’s socks off, but it’s good to see continued development and refinement of a mature OS.

Major change include 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. Both the factory images (linked below) as well as initial OTA’s are rolling out now. Google Play Edition devices should be next in line. Enjoy!
