I want to re-use my old LG L90 as mp3 player by using spotify. I inserted a 32 GB sd-card and my phone is running on android 5.0.2. There is only one problem: when I'm opening Spotify and go to settings, there is no option to move my music to my sd card. My phone recognises my sd card, but Spotify clearly doesn't. Help me, I need to fix this!
