I cant find a contact. When I try to add it again it tells me I already have it installed. Can someone please tell me how to retract it?
Open Contacts, click the 3 bars on the left hand side. The top item should say something like All Contacts. If it doesn't, click on the top item and select All Contacts.
If you have created a contact under say, Samsung Account and have the selector set for say Google, then the contact under Samsung won't show up on your contact list. Set this to All Contacts and it should show all your contacts no matter where they are stored.
