Hopefully someone can help, I have the S3 on tmobile, I have set the text message notification sound in the text message setting separately from the general notifications in settings, unfortunately when on a call I will hear the whistle notification sound as if a text has been received but there is no text message received, I have read other forums that have all been answered usually by another app causing the notification but this is not the case here since the default notification setting is set to off and this notification is text message specific, I am concerned that I may be missing texts so any input would be helpful
Thanks in advance
