When you try to play MP3 files on the Media Player of this phone something odd happens.
If you put a folder inside the "my music" folder (in some models is just "music") it's not showed on the list and the "Auto gen" doesn't recognize it. The only songs added to the list were the ones in the folder 'my music' (or 'music'). It's not reading sub-folders.
There is a 'trick' or more accurate, a hidden option.
If you deactivate the "List Auto Gen' option
'List Auto Gen' ---> Change it to 'OFF'
now when you go to 'Audio Player' - 'List' - 'Option'
there's a new menu and the option 4 (Add) appears and let you select a folder to add to the playlist.
We just need to copy folders of MP3 to the memory card on the phone and add them to the playlist as told.
We can have some order now in our MP3 collection inside the CECT P168
