I just got the Galaxy S4, running android 4.2. Everytime I wanna connect my facebook to a game, for example Fifa 14. It comes up in a small box saying it would like to use my public profile and so on, I click ok. But no apps or games even recognize that I have just done it, because it goes back to "connect to facebook" so I click it again and its like its just going round in circles. So it never actually connects to it.
