Hey there
Sorry to hear of your issue.
If it is only happening on Spotify and not in general use, then this is likely to be an issue with the Spotify App itself.
Recommend you:
Clear cache in the App
Go to Device Care and optimise
Restart your device
If this continues, please reach out to the Spotify App Developers via the app in the Google Play Store.
I am not employed by Samsung nor do I receive any remuneration as a Samsung Members Star.
My device is an S25 Ultra.
