So, I have a Galaxy S4 (through Sprint, not sure if it matters), and I got an SD card so I could throw all my musics on it, but the phone keeps deleting my music.
So, I have tried both connecting the phone to my computer directly with a USB and removing the card and plugging it straight into my computer (adapter) to add music. In each case I can browse to the folder, find the music, and even listen to it if I hold down the file and hit "play". So, it works, but then the minute the card isn't connected to the computer and I actually load up a music player (either of the players that came with the phone) it just eats the song. The song is entirely wiped from the card.
The weird thing is the phone can detect the card no problem. I can browse it in files and see subfolders and browse those. It shows up in my settings menu and everything. Plus, the very first thing I did was to plug it into the phone and format it, so that's done. When I connect the phone to my computer, I can find the card, it's there, I can navigate everything, that's all fine.
I just want to listen to my precious tunes. How do I make this happen?
