The settings button doesn't do anything for moving across devices, because the custom location feature doesn't move all game files.
If you're moving devices and not using a custom location yet, the safest option is to open the lazer folder (there's a button in settings for that too), and copy the entirety of it across. (client.realm, the .ini files, and the files folder are the most important here.)
If you're using a custom location then this gets a little more complicated, so I'll just go with the simple version for now.
