I cant find anything on this, and Im quite confused. My wife just got the d4 and we took the sd card from her old phone (lg ally) and put it in the d4. When I got to file manager, it only shows a couple folder and the folders it does list are said to be empty. If I go to system, it shows that the card is using about 1.5 GB worth of data. Is there somethign special I have to do to get the d4 to read the card right? The card works just fine. I just took it out and backed it up on my computer.
