This is a good tip. I'd start with that one.Ann in Arlington said:Alternatively, go to 'notification settings' and page through to see what you have set with notifications ON. . . . find the one and turn it off. I think notifications are all ON by default so I really think it's a game or something you got and, for some reason, the notification of an update is in Japanese (or maybe Chinese).
