I purchased A Samsung Galaxy S*+ and have a 32 gig sd card that I am using as expandable memory. I would like to move all of internal music, stored in the phone, to the SD card but I do not see that option under the "My Files" menu in the phone. Is it possible to transfer the music to the SD Card?
You can try another file manager application like es file manager. I have used that for years now and is a pretty good one.
It doesn't appear there is a native way to do so in the listed instructions. A file manager app may be able to help!
