LGL 34C 4.4, from tracfone. not yet activated. wish to transfer music files. I'm able to move no more than 2G of music files from pc (linux mint 17). I can see that it's all gone to hd, nothing to sd card. I'm not sure I even know the right question to ask: does this involve rooting, or is it something basic which I didn't do to card when I installed it? never had one of these phones before. thanks, any and all.
