I have Android 5.1.1 (Lollipop) and a 64Gb SD card. My phone is a Samsung SM-200JY and I can't use SD storage. I have tried the workaround restart methods and the only one that works is closing it, turning it off and removing the SD card, then reinserting it upon startup of spotify. However, the SD card disconnects as a viable storage device after a short time and reverts to internal storage. I cannot find any of the files for deletion under the given folder location. I have a lot of music and so an SD card is needed, any help would be greatly appreciated.
