Hello there. Lately i got the problem with my phone (sony xperia z5 dual e6633 with android 7.1.1) - its randomly start playing music via Black Player app. It happens at night when i am sleeping (since i have multimedia sound turned off - i do not hear it then, but in the morning i see the app started and playing the music and the last.fm scrobbler with 50-70 new scrobbles), which is pretty painful for me since : dead battery in the morning = no music for me for the whole day. It happened to me 3 tiems in last 1.5-2 weeks.
