I know this is more of an app question than a hardware question, but since I have only experiences this issue since getting my 9850:
I installed Google Sync from m.google.com, and at first it worked great, but then it started duplicating my calendar entries to the point that I had 111 copies of the same entry in some instances. I searched, and the only solution I found was to Sign Out of Google Sync, which should delete all duplicates, and then re-sync. I tried doing that, but it didn't remove all duplicates.
Does anybody know if there is a setting I need to check to get this to work? The problem is that I need my main calendar and all delegates synced. Is there another app that works better than Google Sync?
You should get the option to google sync on initial setup. I would delete the app. Then delete all calendars. The go into setup and sync google,contacts,calender from there
