1. I am user of galaxy s7 edge with Inear stage diver 4 and BOSE soundlink mini 2. When I disconnected my IEM from GS7E, a music was stopped whatever I checked many options from headset/bluetooth. Also, a music was stopped when bluetooth was disconnected or connected. 2. There is quick connect option at notification bar of gs7e and from there I can switch output either Headphone or bluetooth speaker. But when I switch option a music was stopped while other players (Samsung music, Neutron Player, etc) was not. Those two issues are what I feel uncomfortable about poweamp v3. Except them, it is the best music player I ever heard.
