On my S5 my contacts initially had all my Facebook friends in my contacts which I didn't want. Fortunately I could go into the settings & disable Facebook contacts from showing up. Now I find that on my N5 they have been merged with my Google contacts and I can't figure out how to get rid of them from my contacts list with manually deleting them one by one. I'm not a happy camper about this as I've got over 300 fb friends which is going to mean a lot of time to delete them. Can anyone she'd light on why this is the case and how I can fix it?
