I preordered my X3 two weeks ago, I hope this ID3 tags issue will be solved soon. According to James from Fiio on Head-Fi :
-Music play Back： Play All, Folder Play, Album Play, Artist Play, Genre Play, My Favorites.
-Play Display： Album Cover, Lyric，ID3.
Found this :
@James, i have a problem in updating my playlist, and my categories are blank.. but you can access and play the files perfectly fine in 'browse file'.. I tried restoring and switch version of firmwares to no avail... Can you look into this? tq very much ( i am using mp3 and FLAC)
please try to update the music lib first in the system setting menu.
I did that and now the files from my micro sd card are showing up sorted and not from the internal memory :/ As i haven't actually updated my X3 firmware since i got it, it could be that this has been fixed.
FYI we got stock today of X3 and have started to ship some out, the bulk will go out on Monday/Tuesday.
