Spotify randomly starts playback without user action

[depesz]

For ~ a month my wife has a problem that her phone starts randomly playing songs.

We did uninstall of Spotify, and reinstall, and it did fix the problem, but only for a week, and then it's back.

How/When:

most commonly when she just finished phone call (didn't listen fo music before call!), or when she exits car (when it was playing via Bluetooth.

But also, sometimes, in case where phone just is on the table, nothing touches it, there is no bluetooth device near - and it just starts playing some music.

Right now we disabled bluetooth, and we'll see if that solves the problem, but generally we'd like to have bluetooth on, and not have spotify start playback randomly.
