The Galaxy Note 4 and Note Edge both came out a year ago, a time when manufacturers still shipped their devices running Android KitKat. Owners eventually got to experience Lollipop in a later update, and as we’ve seen from Sprint and AT&T, carriers have started pushing devices up from Android 5.0.1 to 5.1.1. You can now add T-Mobile to that list.
The over-the-air update pushes the Note Edge to build number N915TUVU2COK2 and requires a 150MB download.
