I have noticed lately I have many duplicate contacts. You don’t notice them until you go to edit a specific contact then prompted for which on. When I edit the phone number on one, only that particular contact is updated. But if I edit the name of one of the contacts, all of the contacts with the same name get updated. Everything I read on line to correct requires a Google account which I don’t have. Are there any suggestions to clean up a contact list?

Just an update: I exported list to vcf and edited file with text editor. So now I want to import my revised contact list. But before doing so I wanted to delete the current contact list. Without manually selecting each one, I don't see how to do this. I even deleted all data of the contacts app but all contacts remained.

    mrtoo I even deleted all data of the contacts app but all contacts remained.

    Even after the phone reboot?

    @mrtoo You have to clear app data of the "Contacts Storage" app, not the Contacts app.
