My phone is an LG-V20 by AT&T. Contacts list has started to display caller ID by "nickname" only. Very annoying when you have 5 Bobs, 3 Bills & other multiple named individual friends. Settings only gives option to sort by first or last name but no choice of what name to display. Have just had the latest version of OS installed-no change. Sync is with Google on-line Contacts, here I have filled in all the "Nickname" fields with individuals's common-called nickname. If I delete the person's nickname field in Google or on my phone. that person shows in the phone Contacts as specified in the settings sort choice. How do I change the apps behavior in this manner of locked display of nicknames only?
