An update out to the T-Mobile models of the Galaxy S7 and Galaxy S7 Edge today that not only includes “various system improvements,” but should fix power and volume key issues, assuming you were having them.
Each update will arrive as software version UVU2APD7 and weigh it at roughly 164MB.
To check to see if the updates are available to be pulled, head into Settings>About device>Download updates manually.
UPDATE: The update is now live, a day later, and includes a FM Radio function.
