How do I switch from a Portable SD card to Internal SD Card on a Samsung Galaxy Tab A?

So I've seen many guides on how to do this, but none of them work or are relevant to my device. Thing is, there is NO three-dot menu in the settings.

If there is no "3 dot menu" on your device, then the manufacturer has restricted this option on that device. Nothing you can do about that.
