There is a standard application of FM-radio on the eXperia Z2 smartphone. How I can control this application with use of Smartwatch 2 SW 2?

I've never seen such an app for the SW2 - Not seen any 3rd party apps that would do this either

I too didn't find.

Why Sony didn't make such program for you equipment?
