Hello - I just got a new Samsung Galaxy 7 and installed the Spotify app. I open the app and start playing my playlist. I have my screen set to lock so once it does this I can see the Spotify notification if I push the power button to light up the phone screen. However, after a few songs (always when transitioning to a new song), Spotify stops playing even though it shows in play mode. I unlock my phone and it then immediately starts playing the next song. Does anyone else have this problem?
