I have trouble with my Samsung Galaxy s3 mini: Whenever I remove the SDHC memory card (after turning off the device of course), and re-insert it, then it forgets all playlists which I have created with the built-in MP3 player (I want to create playlists while I am travelling in the train - so it is not of much use to create M3Us externally and put them in a folder of the SDHC card).

Now I have bought a bigger memory card, transferred all MP3 files to it and want to use it in the phone as replacement of the smaller card.

So I am looking for a way to backup the playlists (not the entire MP3 files, just the list containing the file names and path).

The phone has a playlist folder, containing the playlists, but when I use a USB cable to connect it to the PC, I can see them but they have 0 bytes and cannot be copied. Also, if I connect the SDHC card via cardreader, the files aren't useful.

Do you know how I can backup the playlists without losing them? Samsung Kies also did not work for me.
