Can you tell me what GB is? I'm totally confused. I have my zedge notifications and ringtones copied to the system with my other default android sounds. However, just recently, my zedge ringtones are not playing--for instance, for my text notification. They worked fine before, but all of a sudden they do not play. It always sounds the default notification I have set for the phone. I have set a particular zedge tone for my texts, but it does not play. Only the general default notification sound plays. Not sure why my text notification does not work properly...
