hi! i have Poweramp v2 installed on my old lg e400 (android 2.3.6) and i have this problem that whenever the screen turns off it stops playing. i noticed that if i press play and then switch off the screen (which stops the music) and then straight away turn on the screen again, press play and turn the screen off again then it doesn't stop playing, i don't know why that is... Does anyone have any fixes?
