After creating a contact, you can change the name, photo, and other contact information.
Adjust settings as needed:
If you have two contacts for the same person, you can merge the information (including all emails and phone numbers) into a single listing.
Automatically merge contacts
Touch Merge duplicates.
If you don’t see this option, contacts can't be automatically merged.
Merge contacts manually
Touch the primary contact to merge.
By default, this contact’s name is used for the new listing.
Touch the name of the contact to add.
You can delete contacts created and stored on your phone. If the contact is synced from a social network account, you need to delete the contact in that account. For example, a Facebook contact must be deleted from within your Facebook account. Or, hide Facebook contacts on your phone by filtering your contact list.
