Contact groups give you way to categorize your contacts. The contact groups are mapped to server address books. If a contact is not assigned to a group, it will be added into a default category and may not be where you expect it to be on the server side. Follow the instructions below to create a new contact group.
1. Select the Address Book (Contacts) from the device’s Home screen.
2. Scroll right to the Group tab.
3. Select Options > New Group.
4. Enter a name for the new group.
