I'm not sure why but I've got a problem with people disappearing from my contacts. I'm fairly sure it has something to do with Verizon cloud backups but even when I save them as a Google contact it happens too. The one I'm most aware of is my daughter. I'll get a text and her picture and name will be missing. I'll check my contacts and she'll be gone. I'll reenter her card and a week later I'll notice the deleted cards will reappear and I'll have 3 cards for her. It doesn't matter if I enter them as a Google or Verizon contact. I've had one other contact with this issue that I'm aware of and I not sure how many of my other contacts have been affected.
