my phone is xperia miro st23i. I have one question that why the song that I recently added to walkman, always disappear after I was turning off the phone. When I was turning on again, and wait for a sec cause this phone need to find my sdcard and then I choose walkman in the playlist, newly added section. I checked and there isn't new song that I recently added and when I checked the artists/ album, a few of them were disappeared. I even didn't delete the song. Please help me, is my sdcard broken or what? cause I already got stuck at this case 3 times. Thank you for helping me.
