I've been having issues with the Sony Xperia Z when trying to log in and authorise Facebook on the app Subway Surfers.
From what I can tell people using other handsets don't seem to have any issues so I'm wondering if there is anything I should do on the phone to get this working?
I have tried reinstalling both the Facebook app and Subway Surfers many times and it still persists.
Well, out of nowhere it worked!
I started up a different game that also required a Facebook log-in and this seemed to fix the one in Subway Surfers!
This may fix the issue for anyone else who has it. 
You can find the whole help here .. All you have to do is delete the Facebook apps and your Subway Surfers game and download it later and install it first and then the facebook apps
