Solved! Acatel fierce 4 SD issues

Solution
There could be something that was preinstalled on the SD card that is taking up space. Or something you (or whoever had the card before this) had on it. The only want to know for sure is to format the card to clear it off.

If it still says it is only 15 after that, then there is something wrong with the card.
