Hye guys, I have a problem with my notification (SMS) tone.. I set it with one particular tone, but after some time it changes to another sound file! Like today, I got a message and the tone rang as usual, but after a few hours, it changed to a song from my MP3 list.. I didn't do anything since my last SMS and it was left untouched until I got another SMS after a few hours with a song playing instead of my normal SMS tone.. So far it happened to me more than 3 times.. Why is this happening? What could be the cause? I've rooted but using stock 2.1 rom..
