for some reason i put my device to Mass Storage Mode (MSC), uploaded my videos to my external sd card and then when i wanted to listen to my music stored in my Exr_SD it stated music library empty. I have tried several options, mount, unmount the SD, returning to Media Transfer Mode (MTP), moving files from SD to internal storage and nothing works. The problem is only with the build in music player I use another program to watch my videos and it doesn't have problem with my SD card, also my file explorer works wonderful with my Sd card.
