When T-Mobile added a new update tracking progress meter to its website last week, the Galaxy Note 3 was listed as undergoing T-Mobile testing, the second step in a three-step process to deliver Android 5.0. Soon it should be moving up a notch, as a changelog has hit Samsung's site saying that today's the day the carrier starts pushing out the over-the-air update to consumers.
In addition to Lollipop, the changelog makes references to Wi-Fi calling, including a fix for a one way audio issue. But that's not the point here. When people click the update button looking for software version N900TUVUFOB5, they're looking for the latest version of Android. Everything else is just gravy.
