On Froyo, it seems whatever I do, my SGS is rendered useless if I try to sync with my Google Calendar. Whenever it starts to sync the calendar, all other functions - even making and answering calls takes ages, and syncing never ends. The Google account is on my own domain under Google Apps Business.
I just got the phone and never really ran anything than Froyo, so I can't tell if this was introduced with Froyo. I can sync fine with the Exchange server at work.
To remedy I tried:
-Factory resetting several times
-Removing the 16GB SD card - and Factory resetting again.
When I finally can access the setting to disable sync for the calendar of my Google account, it seems to continue trying to sync, and the only thing I can do is to shut off the phone again and leave it off for at least five minutes before turning it on again. If I turn it on too quickly it will try to sync the Google Calendar again and slow down the whole phone again.
Is this a known issue with a fix?
