Check your "My Verizon" contacts
If you are experiencing problems with your X's contacts, particularly multiple "links" that refer to a "phone" contact ... go online into your My Verizon Account > email > contacts. Clear all the contacts, unless you are actually using this for your backup.
Gmail/Google keeps and syncs a current list of your contacts from your X. The My Vz list is a multiple duplicate with old info, deleted contacts, etc. residing right there to be linked to your Gmail/Google list.
This would be most helpful for those who aren't operating on a Google/Android system. But there is a tremendous conflict between Google and Vz for your base of information. "My Vz" has recently become yet another Gmail-type website where all information is backed up/stored.... and conflicted.
