S25 Calendar alerts not working

[JV0762]

Had my S25 for 3 weeks and Samsung Calendar alerts for upcoming events are either not appearing at all or popping up at random times before or after the event.

Tried uninstalling and reinstalling calendar, clearing cache and data, all usual fixes but no joy. All settings are identical to that on my old S22 which worked fine. Can anyone help please?

Yes, no pending updates

I have downloaded the Good Calendar app in the meantime as it appears to be closest to the Samsung Calendar. Surprised others haven't reported the same issue. I have reported it to Samsung.

I've got the same issue. Tried everything and the online support was absolutely zero help... they told me to go to a service centre as this was the only way they could report the issue!

I have the exact same issue and nothing is working for me. Really regretting upgrading to the S25, feels like I've gone backwards.

Seems this isn't just the calendar, the S25 phones are just messed up.

Thanks for that, I'd no idea of the scale of the problem. Thankfully all my other notifications work perfectly well.

I think the worst thing for me is these 'stars' trying to suggest a cache clear is going to fix what is clearly a huge issue that needs resolving on Samsungs end.

Having the same exact problem since my "upgrade" to the S25 Ultra. Calendar worked perfectly on my S21 Ultra. No notifications from calendar are coming or if they come they are very random. Tried everything, delete cache, check notification settings, check deep sleep settings for apps, check battery saving settings. Nothing has worked. Why is this not being fixed?

Has anyone managed to get this sorted? It's started doing it (or more accurately not doing it) on my phone since I upgraded to Android 15 One UI 7.0
