T-Mobile Galaxy Note 4 and Note Edge getting Android 5.1.1 update

T-Mobile has started rolling out a new software update to the Samsung Galaxy Note 4 (N910) and Galaxy Note Edge (N915) devices on its network. The update bumps the handsets to Android 5.1.1 and brings a couple of new features including Advanced Messaging and T-Mobile Video Calling. If you recall, the carrier started rolling out the Video Calling feature back in September this year, making it available to the Samsung Galaxy S6 edge+ and Galaxy Note5 first, followed by the Galaxy S6 and Galaxy S6 edge. It was promised that more devices will be added to the list by the end of the year, so T-Mobile has made good on the promise. Aside from the aforementioned two features, the update also brings some security, performance, as well as battery life related improvements. If you are a T-Mobile Note 4 or Note Edge owner, and haven't received the update yet, you can also manually check for it by heading to your device's settings. Source 1...
