Phonecall quality suffers while Spotify is launched?

[upsidedowntatto]

Hey Guys...

... I´d n phonecall yesterday. So caller pleased my to come closer to mic ´cause of the bad quality of transmissen. I just tryed without any reason and closed spotify (without telling). Then the caller told me, that the quality of transmission seems to be much better. So I tryed few times and it seems to be something like the App disturbs the phonecall. At least I´m not realy sure about. For me theres no way to validate this experience.

Greetings, Boris
