For some context i have an samsung s10 plus and my friend has an samsung s7 edge. On my friends s7 when he connects his bluetooth headphones they show up as a playback device in spotify. When i do the same thing my headphones don't show up as a playable device. I can still play music on them but they don't show up as a playback device in spotify. Also i checked the spotify version on my phone and my friends phone and they are exactly the same. So i don't understand why he who has an older phone has newer features than me. In the screenshot below i have circled in the spot where instead of just the regular grey icon my friend has a bluetooth icon when playing trough bluetooth headphones. It also says the name of the bluetooth device in the same spot.
