I just received my Nexus 5... Concerns.

I went from a htc one x to a nexus 5 and the experience so far has been sub-par.

Why don't my facebook contacts sync or display pictures of contacts? facebook displays in my account under sync account but it doesn't do anything (it can't sync like my google account syncs).

And what is up with the hangouts instead of text messaging? I don't use google hangouts and I have all of these spam emails as contacts? WTF.

Otherwise, the phone flies and looks amazing. Please help me on some solutions. I don't want to sell this phone but this is a deal breaker. I don't like being forced into using services that I have no care for.
