I use Spotify they've disabled the bass boost on that function for some unknown reason.
also I know the volume is lower I can hear my self sing at times never a good thing lol
Loving the pie very slick.
So it seems that the bass boost function has been disabled in Spotify and Google's own music app.
There is a work around and involves downloading a 3rd party app.
Nokia say it's an issue with those two apps.
I am waiting to hear what Spotify say.
