About 3 days ago my fone gave me a low space message. I thought it was the SD card, so i went out a bought 4g one. i Put the new card in, and i still get the low on space message. I don't think my fones registering that i have the SD in.. every time i get a text it says "Message Deleted do to low space" or something like that. My inbox is completely empty. Ive gone to my SD card settings and it tells me that i still have 3.8G's Left on the card ready for use, i could use some help. Thank you.
