Having had the "activate auto-sync" checkmark off for about a week (not that i expected this time-out to matter in any case), i've recently tried to find a manually-driven option, but without success. My 2.3.4 Gingerbread (Level 10) doesn't even animate the curved arrows anymore. After giving up, i've even activated the auto-sync, but it still did not kick in. :-|
Then i tried to look into other options, and got to the Contacts app, where in the Menu there's an "Import" option, but this one fails to even start -- with a silly error message "Memory full. Could not import contacts." My internal storage still has 16 MB free, though, so i suspect it's the number of contacts that's causing the issue? So, anyway, how do i check what's wrong and is there any workaround for this SNAFU?
