T-Mobile is the last of the 'big four' carriers in the US to push out the Lollipop update for its Galaxy Note 4 units, but it's finally done so today. This follows similar rollouts already commenced by Sprint, AT&T, as well as Verizon - many weeks ago.
Yet if you bought your Samsung Galaxy Note 4 from the magenta carrier you've been patiently waiting to get a taste of Lollipop, until now that is.
The update comes over-the-air in the form of a 1.1GB download, so you'll have to get it via Wi-Fi. Other prerequisites to perform the update are at least 50% battery life at the start of the procedure, and 3GB of free storage.
Once it gets going, the download should take around half an hour to complete, while the installation itself may take up to an hour, depending on the number of apps you have. After everything's finished, you'll be running Android 5.0.1, software version N910TUVU1COD6.
If you haven't yet received the update notification, you can manually check through the About phone Settings menu, or use Kies, Samsung's desktop PC software, to install the new bits.
