my volume is low when I play over bluetooth, my friend tried on thier account with thier phone [iphone] on the same bluetooth speaker and it was louder than mine. my phone is cranked up to max. im pretty sure its just spotify as i used to use pandora and that played fine (that was maybe a month or two ago). 

i've uninstalled and reinstalled. that didnt work. i did delete cache but i have yet to try it, (wont be until monday) i havent messed with the eq, i have normalize volume enabled. I use wifi for the streaming, and its in automatic quality. if you need more info let me know and I'll try to get it to you.

Posting this now so i can hopefuly find out whats wrong and try fix it at work (we listen to music at work from one of our playlists) during a break.
