I have a samsung galaxy S2. I uploaded some music to my SD card the other day. Everything was fine. Then yesterday every 5 mins my phone sends me a message saying "SD card unexpectedly removed". Then I have tried rebooting my phone. Took sim card,SD card and battery out. Ive checked the music files,removed and re-added them..not sure what's going on..not even sure it has anything to do with the music or not. Please help!
