Google has started rolling out the recently rumoured Android 5.1.1 build LVY48C over-the-air (OTA) update for all Nexus 6 phones bought from Project Fi.

The new Lollipop update brings a host of bug-fixes along with some Project Fi-specific changes to address connectivity issues in certain areas of the US. This information comes from user Justine Rivero, who recently posted on Google+ that the Project Fi 5.1.1 OTA rollout had started for the Nexus 6.

The OTA update is only a mere 92MB in size and works on any Nexus 6 running the previous Lollipop build, LVY47H. Meanwhile, those who are using a non-Project Fi version of the phone may have to wait until Google rolls out the factory images.

IBTimes UK reminds readers that it will not be held liable for any damage to device during or after the Android 5.1.1 Lollipop firmware installation. Users are advised to proceed at their own risk.
