I can pair and connect to the Samsung Galaxy S4 but I cannot control the phones features more than one time.  I have been able to get it to play music with S-voice but it will only take the first command.  I can also get it to give Navigation features but only once.  Do I have to use the phone to do everything and just use the Sena as a headset?  If so I will send the Sena back.  I can only say Hi Galaxy once without having to go back to the phone and using the buttons.  Help.  I like the Sena 10R but I need an interface that works.  Are there any 3rd party apps that will do the job?
