Xz premium bluetooth problems

[Gtibroeder]

Hi there,

I am having trouble operating my phone in my car via the steering wheel with bleutooth I drive a Volkswagen golf7 mk7. Previously I did not have any problems with XperiaZ3. . . Also, from the beginning, I get an error message that 2 sending of photos have not been successful. I can not delete this error because it is not in the list of transmitted or received bleutooth  files, I have re-enabled the bleutooth and removed the cache but I have no effect, it's really annoying because it's a good phone look at the screenshot picture to see what error i get

 Hello ! I have just changed smartphone and now I have got a new XZ Premium. I have a problem with bluetooth connection with SmartBand Talk SWR30: when I switch off the bluetooth connection on the XZ Premium, the SWR30 continue to stay connected ... I must switch off SWR30 and switch on again to get it disconnected !!!

 With my old Z5 Premium (same Android version, 7.1.1), it was all fine. Can someone help me ?!?
