I just upgraded from a Galaxy S23 Ultra to a Galaxy Fold 7.

And doing the same thing, i've always done to play music, which is to open the spotify app, click the speaker button to connect to my sonos and then play music through the spotify app. With this new phone after about ten minutes or so the sonos stops playing and the music kicks back to playing on the spotify app on the phone.

I can reconnect it and then ten minutes later, it does the same thing. This last time after I reconnected it by clicking the speaker button in the spotify app I turned off wifi on my phone. Thinking somehow that might do something.. But it didn't, it ended up kicking back to the phone anyways.

I have about a dozen sonos speakers on my network. But I usually only play 3 to 4 at a time, which was the case this time. I have an eero 6 pro wifi mesh setup.

I don't know if this is a spotify issue or a sonos issue but I figured I would ask here first, thanks!

It sounds like an issue with your phone maintaining a connection to your WiFi, but since Sonos won’t have data, it’s hard to suggest a diagnostic through Sonos. I’d suggest a network refresh, by powering off your phone (all the way) and Sonos, and while they’re off, reboot your router. Wait for the router to come up, then power on your phone and Sonos speakers. 

I suspect if you submit a diagnostic in the Sonos, it will just suggest a disconnect from the source (your phone / Spotify Connect) and not give them much data to look at. But I suppose there’s a small chance that it might show another reason, so it would merely be effort on your part to submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. But as I said, as you’re using Sonos Connect, it’s unlikely they’ll ‘see’ much, since you’re ultimately using someone else’s software. You may want to try Spotify’s support, I don’t use them myself, but they may have similar data that they can access to give you a better answer.

FYI after a Spotify Connect session is initiated, the stream on Sonos does not rely on the phone connection. The stream is obtained directly from the Spotify servers. The phone can be turned off and the music will continue playing on the Sonos speaker. 

@slikk66 - If you close the Spotify app on your phone, does Sonos play longer than 10mins? If so, then the issue would point towards the Spotify app on your phone reclaiming the audio.


That’s odd, how does the UI on the phone maintain control over the stream?

When the phone has a signal, either cell or Wi-Fi, I’m assuming the Spotify app communicates with the Spotify servers which then communicate with Sonos, rather than the the link being Phone > Sonos. Therefore, the native Spotify app will show the respective Sonos room as the connected device and the Spotify app Now Playing screen reflects what is being played on Sonos.

If you then turn your phone off (airplane mode), you can access Spotify app and play any downloaded content on your phone, whilst the Spotify Connect stream continues on Sonos. Disabling airplane mode and accessing Spotify will then ask you where you want to play audio as account is limited to one stream. Although playing Spotify via the Sonos app allows multiple streams on the one account.


@slikk66 - This Spotify support page for Spotify Connect states:

Note: If you pause playing for more than 10 minutes, you might need to reconnect.

Your issue could therefore be Spotify incorrectly believing the stream has been paused and disconnecting from Sonos?!
