The official Twitter account for Project Fi gave an update on the status of Android 5.1.1 for its Nexus 6. There, it was specified that owners of the Nexus 6 with Google’s wireless service can expect to see the software update arrive “over the next few days.”
Good news! Android 5.1.1 – an even sweeter version of Android Lollipop – is coming to all Project Fi phones over the next few days.

Don’t have an invite just yet? The wait is almost over. All invites are said to be sent out by mid-summer and Project Fi currently allows you to check the status of your own invite. For me, I was told about ten days ago that my wait was 3-4 weeks but received it earlier this week. So it looks like Google has been able to get invites pushed out at an increased pace.
