Xperia Z1, all software (Android and Spotify) at latest version.
Sometimes, the widget won't show on the lockscreen - I've no option to add an actual spotify widget, there isn't one in the list. Later, it'll just turn up again. No idea what changes its mind. Having googled, I don't have Smartkey installed and have never had it installed
Occasional spontaneous complete-loss of the play/pause bar in the app - no way to stop music playing other than to shut the whole app down
Regular loss-of-place in playlist. You can be winging through some hundred-track playlist, come back to it later and it's lost where you were. No option to just hit play and hope it'll work it out, as the Play/current button is also missing.
Playing music through bluetooth, a facebook notification ping will come out on the phone speaker, taking the music and playing it through the phone for a second while that happens. Not the end of the world, but then when it switches back to the BT audio, there's no sound (tho the track is still playing)! Have to pause and unpause the track again for music to resume. Resolved this by disabling facebook notifications, but it's a bit of a hack..
Spontaneous messages that the track/album has been removed, when it hasn't.
I've had most of these bugs for months. Not very impressive...
