Synchronization unreliable

[sunkup]

Now and then, there are sync issues on Android 15+. It only seems to affect some people, sometimes it goes away by itself and we have not been able to reproduce it ourselves.

It would be interesting to log more information on the workmanager status

See:

• Synchronization interval not working #587 (Android 15, Galaxy S21+)
• sync interval failing #547 (Android 15, Lineage OS 21.1)
• ical4android update introduced periodic sync failure on some GrapheneOS devices #534
• Auto sync failing in 2.2.6 #489 (Android 15, GrapheneOS)
• Periodic sync still broken #528 (comment) (prob Android 15, Pixel)
• Periodic sync still broken #528 (comment) (prob Android 15, Pixel)
• Autosync fail #628 (Android 15, Samsung s22)
• Syncing stopped working #681 (reply in thread) (Android 16, Pixel)

Finally I was able to see it for myself. I did not have a debug version installed though, so will do that now and hopefully catch some of the new workmanager stop reasons in the log the next time it happens.

I have experienced auto sync issues too sometimes with icsx5 version 2.4.3 on latest GrapheneOS. I happened to open the app, saw that none of my calendars were synced sinced 2026-02-09. Then I manually synced and everything got up to date again.

I also have this problem. I have version 2.4.3-standard from f-droid on my phone (Fairphone 5 with android 15). Is there any way I can help pinpoint this issue (logs, etc.)?
