Do any of you guys use the LG V60 or G8X with the dual screen case for 3DS and stuff?

I don't have a Bluetooth phone grip controller yet, but I figured I might as well just start using it with the touch screen to play 3DS jrpgs, but I can't really figure out how to get the screens setup good with Azahar and all the halfass "guides" online that I've seen are so old that they're really no help.

(The thing that's really annoying about these phones with the dual screen case is you need this homebrew app to get most applications to display across both properly, you constantly have to re-enable it, and it's very finicky with crashes and stuff.)
