It's Android 4.4.4 update season for Samsung smartphones sold by US carriers, it seems. Following in the footsteps of Sprint's Galaxy Note 3 and Verizon's Galaxy S5, it's now the turn of T-Mobile's Galaxy S4 to be updated.
Android 4.4.4 is currently the latest release of Google's mobile operating system. The update for TMo's Galaxy S4 is rolling out over-the-air but can also be grabbed by using Kies, Samsung's desktop PC software.
If you want to install the new software, make sure your phone has at least 50% battery left, and keep in mind that you can't update if your handset is rooted.
The update comes in at around 400MB. After applying it, you'll be on build number M919UVUFNH7. Aside from all the bug fixes and enhancements that are built into Android 4.4.4, the new version brings with it support for T-Mobile's free inflight texting offer (made possible through a partnership with Gogo).
