Organize Contacts
One reader asked how to organize contacts within the Contacts app so you can have the same categories for all contacts, no matter what computer or device you're using. The only way you can do this is to create one master contact list on one computer or device[md]or even on a web-based contact service such as Google Contacts. Then you can import from that one master contact list to all your devices, including the Tab 4.
If you're using the Tab 4 Contacts app as your master contact list, you can add or remove a contact to or from a group when you view a contact. Note that if your contact is in a Google+ circle, you can't add or remove a contact to or from a group.
Tap the name of the contact and swipe down the Contact Details page, if necessary, to view the Groups section.
Tap on the group names to open the Select Group window shown in Figure 3.
Figure 3 Create a group by tapping the Create Group button.
You can add or remove the contact to or from one or more groups by tapping the check box to the right of the name. When you're finished, tap Save in the menu bar at the top of the window. The group changes appear within the Groups section in the Contact Details screen.
