On my totally stock Bell Samsung Galaxy S2 I have my main GMail account synced to it, it is also synced to my iPod using Exchange ActiveSync.
My phone's default calendar has all the events from my Google Calendar that I had been organizing and creating events from my iPod calendar with. However, when I create a new event I get this error. I tried going to the Account and Sync settings, then syncing the calendar, but the wheel stops spinning after a little bit, then just disappears and the problem remains.
I tried creating a test event, then checking Google Calendar on the website from my laptop and the event was there. Even today, I made an event on the phone and it's on the web page. In fact, I just corrected the time of the event from the web page and the change was reflected almost instantly on my phone.
I tried unchecking the account sync and then deleting local calendar data, then rebooting and resyncing. But the problem persists.
What's wrong? Is there anything I can do? (besides factory reset please!) Or should I just check the "Do not show again" box? Or would that cause a problem later on?
As a side note Samsung Kies popped up first saying it couldn't sync, but I couldn't care less about that since I only made a Samsung account for the find my phone feature and the developer stuff.
