On my Moto x 1st generation, my contacts would link with Facebook friends that I also had in my Google contacts - now I don't see anywhere to even show Facebook contacts on the Moto x 2nd generation, and some contacts link while others don't and I see no rhyme or reason to it...also, not a problem but some of my contacts that I actually DON'T have as Facebook friends actually show their Facebook picture by their contact which is bizarre, although not really a problem just a strange observation
