Can't seem to join certain contacts together
So I downloaded all of my Facebook friends into my contacts, and figured how to join my phone contacts that had already transferred from my old phone with the FB contacts.
Except. Some of them just won't join. I just get a blank page when I'm supposed to join them together. Sometimes it happens when I'm trying to join a phone number to a FB contact, but sometimes it happens when I'm just trying to join two phone contacts. There seems to be no rhyme or reason as to how this happens.
I have tried changing the names, the contacts, and I have tried joining from either contact. No luck. What should I do? Is there a fix for this?
