My phone's contacts sync with my Google Contacts, but they are all in the same group (called "Google"). I would like for the sub-groups that I have created in Google Contacts to be accessible from my phone, so I can view/organize my contacts by these groups. Is there any way to achieve this?
The Groups tab in the contacts app shows the individual Google contacts groups, including the built-in ones ("Coworkers" etc.) and my custom groups, and they are browsable. This is on my Galaxy S Vibrant running 2.2, with TouchWiz.
Go to Contacts. Hit menu --> Display options. Under "Choose contacts to display" tap the account (gmail) and then check the groups you want.
I don't know if there's a way to do it specifically in TouchWiz, but on my Droid I had to install Groupy to accomplish this. It works but be careful and test it out first as if you add groups and sync in the wrong order you'll end up with tons of duplicates.
