Ok, none of the existing similar posts had help me. So here's my problem. I'm constantly receiving the file type not supported error for my audio files. -My songs are in mp3 format (has error) -Converted to m4a and wmv (still having error) -Tried winamp (still having error) Not all files actually receive the error. Sometimes a song works, but by the next day, it receives the error. But most often, a song immediately gets the error... I noticed that when I play my music files in my computer, it works. But when I transfer it to my phone, some immediately receives the error. And when I play it back to my computer, it still won't work. What's wrong? I have two galaxy y. Other's from my dad. Mine works perfectly, my dad's having the errors. And he's asking for me to fix it. So pls help. THANKS! my files are always in a uniform format.
