Galaxy Note8 Android 9 - Navidrome sync stuck on Preparing sync

Support

App version

Production

Issue description

On my Galaxy Note8 running Android 9, the initial Navidrome library synchronization completes successfully and music playback works normally. However, every subsequent manual synchronization gets stuck on “Preparing sync” and does not finish. Reinstalling Symfonium did not resolve the issue. The same Navidrome server synchronizes normally on my Galaxy S24 Ultra, S22 Ultra, and Note10+. Expected behavior: subsequent synchronization should complete normally.

Device type

Phone

Media provider

Subsonic (Open)

Steps to reproduce

  1. Install Symfonium 15.1.0 on a Samsung Galaxy Note8 running Android 9.
  2. Connect to a Navidrome server using Subsonic (Open).
  3. Complete the initial library synchronization successfully.
  4. Open the synchronization manager.
  5. Tap Sync for the Subsonic source.
  6. Observe that synchronization remains stuck on “Preparing sync” until manually canceled.

Additional information

Device: Samsung Galaxy Note8 (SM-N950N)
Android: 9 / One UI 1.0
Symfonium: 15.1.0
Server: Navidrome (OpenSubsonic)

The initial library synchronization completes successfully (1,378 tracks). Music playback works normally.

However, subsequent manual synchronization gets stuck on “Preparing sync” and does not complete.

I completely uninstalled and reinstalled Symfonium, but the problem persists.

The same Navidrome server works correctly on my Galaxy S24 Ultra, S22 Ultra, and Note10+.

I enabled debug mode, reproduced the issue, and uploaded the logs.

Please investigate whether this is an Android 9 compatibility issue or a synchronization bug.

Thank you, I found your Note8 logs. They show synchronization waiting on the phone’s local database while Navidrome remains reachable. Canceling releases the waiting queries. This points to a database synchronization problem, although I can’t yet confirm it is specific to Android 9.

The long attempt began before this log recording, and the next attempt was canceled after about 3.5 seconds. To capture the missing beginning, please enable debug logging before starting another manual sync, leave it at “Preparing sync” for at least one minute, then cancel once, disable logging and upload promptly. Please reply with your app version, upload description and the time it happened so I can match the complete attempt.
