I had an issue earlier today with my mp3's appearing multiple times. I fixed this by flushing media storage using Settings > Applications > All > Media Storage > Clear Data (I found that by Googling & it drew me here for the answer :thumb: ) Since then, any incoming messages via SMS & What's App had this annoying synthetic double-ring ringtone. What's App I sorted quite easily but SMS...the thing won't shut up until I read the message. I have tried changing the alert tone but this has had no effect. This is on my S2 which is running 4.0.4. I have not rooted it & Kies has not made an upgrade available yet.. I have tried rebooting the phone, turning off & removing the battery & SIM but the annoying persistent ringtone will not go away. Any suggestions are welcome.
