ok so ive looked everywhere on the internet for this. my SD card is full but my phone storage still has room on it. i get most of my songs from bluetooth or i download it on my phone. since my sd card is full its not letting me put on anymore and ive tried many ways of accessing my sd card but there are no files or anything that will show me whats on it. ive even tried pluggin in my phone and trying to move stuff around but it just seems like all the files have nothing in them!!! i do not want to root my phone. my phone is a samsung galaxy 551. any help?
