Hi I got Moto G 4g (android 4.4) 8gb of internal memory and 32gb in the SD one. I can't understand why but my spotify when it downloads my music, during the download I see the storage gets busy in both of memory slots. It seems that it's saving music twice (in internal memory and in sd card). Is that normal? Did anybody have the same problem? I follow all the steps for make save music in the sd but looks that it didn't work completely.
