There is bug when im using my xz2 with Sony wh100mx2. So the bug is that sometimes the phone doesnt recognise what im using at the momment, for example I was playing a game and when I tried to turn volume up, it was maxing my volume for calls, even tho volume was going higher it wasnt that strong enough because it was for calls. And with android 9 you cant choose what volume u want to change
