Spotify's Android Auto autoplay bug traced to Bluetooth, not just app settings
Spotify users have long reported music starting automatically in their cars even after disabling the 'Start music automatically' toggle in Android Auto. Spotify's support team says the issue often stems from connected Bluetooth devices sending a 'play' command upon reconnecting, rather than from the app itself. There is no single fix, though toggling settings, unpairing Bluetooth devices, or removing Spotify from Android Auto can sometimes help.
