I got my z1 today and i done all as told by the phone and im logged in on my gmail account but cant use google play, everytime i try download or update i get the wrong code 403, and i have tried everything by clearing catche, relog account, creating a million other gmail accounts i tried both wifi and 4g. Plz help 
It seems many xperia users have issues.Any new update for play installed lately?
