Q: Contacts I don't want them duplicated by first & last name

Sorry. This doesn't make any sense.

Sorry. You're still not making sense. Try using punctuation.

Do you mean you see two entries for each contact?  I don't see this behavior. You should see only one entry in the contact list for each entry. The only way you can have more than one is if you've entered each contact twice.

OK... hang on... Who, exactly, transferred them in?

If you had someone at a phone shop... Verizon or AT&T, for example, transfer your contacts from an old phone, especially those stored on a SIM, then you DO have multiple entries. Those transfers almost always result in a royal mess.

Create a new entry from scratch. Joe Smith or something. Then go back and look at the list. Do you see 2 entries for it, one under J for Joe and one under S for Smith?
