The day we have all been waiting for is finally here: Google and T-Mobile are rolling out the much-anticipated (and much delayed) WiFi calling update for the Google Nexus 6 by Motorola. The OTA software update will bring Android up to version 5.1.1, and the build number to LYZ28E.

The update started rolling out yesterday evening to a select few users, and it’s expected to roll out to the rest of us over the coming weeks. If you’re impatient like me, though, you can grab the OTA update here (thanks, XDA!) and sideload it over ADB in recovery. (If you need help with that, the folks at XDA are the best people to ask.)

Here are my first impressions of WiFi calling on the Nexus 6:

  • Call quality is great. It sounds just like calls made over the T-Mobile network which, in my area, is a very, very good thing.
  • HD calling also works perfectly.
  • WiFi to VoLTE handoff is also working, although the call did get a little choppy for a few seconds as the handoff took place. The call was not dropped, though.
  • Conference calling is not working, and VoLTE to WiFi handoff is also not functional.
