I can't change the notification tone for Google Calendar appointments to anything other than the built-in notification tones. If I set it to one of my custom notification tones it switches back to the default tone. The default tones aren't loud enough to wake me up! I haven't seen a fix for it online anywhere, but does anyone know how to access the built-in Google Calendar notifications? They're not the standard system notifications. If I can find these files I'd gladly just replace one with a notification tone I want to use for the time being. I've been using my old Samsung Seek as my calendar since I got my S3 because I can actually hear my Seek when it plays something from the calendar. >_<
