Has anyone found a way to disable this yet? It pops up every time I open the contacts app.
Only way I was able to disable it on my s4 was to edit an xml file. You have to be rooted and have something like root explorer then go to
Data/data/com.android.contacts/shared_pref and edit the xml file there to tell it to not search AT&T for their cloud address book. Below is an example of mine. You can see where I've changed some values to false in regards to the AT&T address book.
