I've tried using Apollo and Play Music apps, and each of them just randomly stop playing music after a while. By that I mean apps compeltely stop working, you can change tracks, it just doesn't play anything at all, and the timer show 0:00 and doesn't go anywhere. It can only be fixed by restarting the phone.
I have CM11 M9 version installed on my device with CWM 220.127.116.11 (i think) on it. What could be the cause of this? It is very annoying.
