If you bought a Nexus 6 from Project Fi, and have been waiting for your Android 5.1.1 update, you’re in luck. Yesterday, Googler Justine Rivero posted to Google+ that the OTA rollout had begun. You can expect all the fixes included in Android 5.1.1, as well as some Project Fi-specific changes to address connectivity in certain areas of the US.
The OTA update clocks in at 92 MB and will only work if you have a Nexus 6 running build LVY47H.
