The Google Pixel phones have been running the latest and greatest version of Android for a while, as you would expect. Next in line from Google you would expect is last year’s flagship, the Nexus 6P, and it appears to be the case.
According to the Vodafone website the OTA update will be released from Google beginning at 5pm AEST on December 6. The OTA update is a whopping 650MB so it is certainly more than just the December security patch (which is included apparently). The update brings the official Android version number to 7.1.1 with the build number being NMF26F. There is a new baseband as well with the new version updating to angler-03.78.
Rumours have it that the Nexus 5X will receive the update to Android 7.1.1 at the same time although this is yet to be confirmed. The rollout beings with only 10,000 phones selected at random to receive the update over the first 3 days followed by another 10% per day between days 4 and 13. From day 14 onwards all devices will receive the update.
So, on the 6th of December charge your phone, connect to some Wi-Fi (or use your phone’s data) and keep an eye out for the update. Let us know when you start to see it on your device.
