I put the old memory card from my old phone into my new LG motion. I erased everything on the card because the phone kept saying preparing SD card. So once I did, it read it and said you may now put things on it. Problem is there is no way to access the memory card. I went to storage and the SD CARD options are faded out such as "mount SD Card" and "Erase SD Card" When I plug it into my computer there is no file for the SD CARD. Help!
