One 'feature' that I've recently found through getting hands on with the Android operating system is synchronising contacts.

After re arranging all my contacts in Gmail I couldn't figure out why some of them were not syncing. I hadn't noticed that Gmail creates three default Groups for you. 'Family', 'Friends' and 'Coworkers' are all default groups created and managed by Gmail. You cannot delete or rename them, and they will not Sync! In fact they do not even appear in the Android groups listing!

I cannot find any options to change this, so my only recommendation is to create a similarly named group, and move everyone into that. I've created 'Friends.', and that seems to have done the trick.

If anyone knows how to get around this, please share!
