Occasionally I get the incoming call number not being recognized as a contact, and the default ringer rings with the number displayed instead of the contact picture and name and the ringtnone that is associated with it. It happens to be the most called number on my phone that I notice it with (wife) so its verizon to verizon. I will go to the call log and after a second or two it will replace just the number with the contact info and pic. I had thought it was the ill fated city id app that did it so i uninstalled it a while back. It just happened again. Anyone know of any other reason?
