Help internal storage

[Android Question]

I added a 15 Gb SD card to my android phone. I don't see an option to make the SD card the primary storage.
Can't download anything because internal storage is full and SD is barely used.

What phone and version of Android are you on?

In order to use Adoptable Storage you need to be running Android 6.0 AKA Marshmallow. If you're running Marshmallow go into Settings and choose Storage & USB, tap on the SD card you should see an option to Formal as internal.
