Spotify takes up about 10GB data on my phone. Half of this is used on the internal SD card, which is becoming a problem. I've had this problem before, have removed Spotify entirely, after which it started to use the external card. Since a while it has apparantly changed its mind, and now prefers the internal storage.
I don't mind that Spotify uses the internal storage for settings or for temporary cache, if that is necessary. I don't mind if that takes up 1GB, but I don't want this. Now I have to download 10GB music, which is a waste of time. Plus I lose the local settings, which albums I want to have locally.
When I look at the app specs in the Android settings menu, I see it reports 9.42 GB on the external card, and 1.48MB on the internal one. That seems like a bug?!
Why does this happen and how can I force Spotify to use the external storage exclusively?
