After sharing the factory images of Android 4.4.3 builds of the Nexus devices earlier today, Google has now started rolling out over-the-air Android 4.4.3 update.
If you own Nexus 5, Nexus 7 (2013 or 2012), Nexus 4 and Nexus 10, your device will notify you of the update as soon as it is available for you. No need to keep mashing the check now button in software update settings, as that won’t bring the update any faster to your device.
The OTA update URL for Nexus 7 (2013) Wi-Fi version and Nexus 5 has already been extracted and you really don’t want to wait for OTA, download the OTA using the link at the end of the report and follow this guide to flash the update.
According to reports, Android 4.4.3 brings security enhancements, bug fixes and updated dialler app (only on Nexus 5, not sure about Nexus 4).
We will update the post once we have more OTA links.
