I'm in the UK and updated recently. Not sure what the controller update is but I can now see how much battery life is left on screen(think it was under settings).
The controller update is supposed to lessen the analog sticks leeway
Oh thank you, can't say I have had any problems so far, but reading the second post it seems just for that game. So no problems for me as I am not getting it. Layton vs Phoenix and infamous for me next month.
