AR Core SDK works on my phone but not AR Foundation

I've been trying to get started on an AR project using unity, but whenever i try to start an arsession and check on the session state it goes from checking availabilty to unsupoorted immediately. The phone is a samsung galaxy s7, which is on AR Core's list of supported devices ( https://developers.google.com/ar/discover/supported-devices ).

So I gave https://github.com/google-ar/arcore-unity-sdk a try and their quickstart project runs just fine..? I was under the impression that AR Foundation was a wrapper for AR COre and AR Kit, so this was really confusing.

Any advice on what to do here? I really want to use AR Foundation but, it just isn't working at this point and I can't explain why.

 

I was following an out of date tutorial that was having me use Unity Remote.
The solution was to just Build and Run.
