I have the D3 with android 2.3.4 kernel ver. 22.214.171.124 system version 5.6.890.XT862 Running the latest version of GO Launcher EX. Phone is not rooted or modified. I'm using the default D3 sms text messaging app. In the last few days when receiving an (sms) text message in addition to my desired (selected) notification alert, it is now playing one specific song in it's entirety from my SD Card's music folder. This all began on it's own without any changes made by me. I've checked my notification settings in the overall settings, and in the text messaging app, everything is correctly set to play my desired notification sound when receiving text messages. I've looked everywhere trying to find out where it's using the song but can't seem to find it. I've also tried shutting down the phone to reboot and it still plays this song along with the selected notification sound when receiving text (sms) messages. I've read some other android users complaining about this but no one never really offered any realistic help except to delete your music etc. Does anyone have any idea why this is happening?
