I have approx 6000 mp3 songs on my SD card. Occasionally while I'm listening to music there will be a sudden static burst, almost like an annoying buzzer for a split second. This usually happens when I'm either multitasking on the phone, and sometimes when I'm entering a subway or tunnel where I lose data connectivity. This brought to mind a RAZR MAXX review I read where the reviewer experienced something similar when using the camera function while listening to mp3's. Has anyone else had this experience or know of a fix?
