Hi

Make sure that all the number you have in your device are still present there or not and even try adding a contact and then check it and tell me what happens when you have newly added a contact and try to call them.

New contact added, had a displayed name. Old contacts still exists in "contacts" but some show the name when call while others don't. They all have the same format #
