Random deletion of calender schedules

[shtengri]

It has happened so many times. Sometimes, some records of my calender are randomly deleted saying 'this schedule was deleted through google synchronization. I did not change any setting, and whatever I try, this symptom keeps happening from time to time. It is even weird that the 'synchronization' randonmly eliminate a few schedules, not the whole. I wonder how can this problem be solved

It will be a setting in one of your calendars. It usually gives you an option as to how long to keep calendar entries so check you settings in your Google account and phone calendar. There is also usually an option to make one of your calendars the main or default calendar which items will be synced to. I hope this is helpful

Don't use Samsung calendar. Use Google instead

I also hit this problem with galaxy s24, finally I removed samsung calender app and revoked the access for the third party apps from google calendar settings (https://calendar.google.com/calendar/syncselect)
