Hi! I have sony xperia Miro which I bought last month, but this problem keeps bothering me.
I created playlist on Walkman app, but few days later the playlist dissappeared and the application seems like reset itself. All of the playlist is gone (include default playlist such as favourite, most played song, custom playlist, etc.)
And it happened almost everytime when I transfered new files (mp3s,photos,documents, etc) from my PC to my device. (I use PC Companion without MediaGo). Sometimes this problem occured even when my device is stand-by. It's been really annoying to me because I need to re-create those playlists almost every few days.
Help, please~ Thank a bunch!!
