When freshly powering on my FP2 and pressing the volume keys the ringtone volume is changed.
Not every time but mostly after I connected my FP2 to blue-tooth audio (Mazda 6 audio and headset) the behavior changes and the media volume is change, when pressing the volume keys. And this even when no media is played any more.
This behavior can’t be changed back by changing any volume in the settings app.
Only rebooting the phone reset this behavior.
Does anybody experience this problem too? I even filed a bug in the bugtracker.
