I recently purchased an S20 FE and installed a 32gb SD card I had in my old phone. I had formatted it before installing and after installing it, transferred about 10gb of music from my laptop to the SD card. Got up the next morning and all music gone from SD card. Transferred it again and next morning same thing, no music on card even though I had been listening to it the night before. Any ideas why, how or where it is going? Possibly a bad SD card? Thanks for any ideas.
