I have a 32GB micro SD card and I've been downloading my music onto it and I've used 8GB on the card so far. Then I was downloading a song and it said insufficient memory. On my phone the songs automatically go to SD card. So I went to storage and it reads the card and says 20GB free space but any app or music or anything cannot be downloaded due to the supposed insufficient space though I know that it's just not true. If anybody else has had this problem please let me know. Any advice would be greatly appreciated.
