I'm running Spotify on a stock HTC One (4.1.2) which has HTC's implementation of Android lockscreen music controls. Any player that supports ICS/JB lockscreen controls shows them on the HTC One's lockscreen. Spotify, however, shows them very inconsistently. For example, if I play something, then turn of the screen and turn it on again, the controls will likely be there. if I unlock the screen, then lock it again, odds are, they'll be gone. I can't seem to pin down what causes this, but it drives me crazy. Every other app keeps the controls there while music is playing, reliably.
Can the Android dev team look further into this please? Thanks!
