Hello, I am trying to test the surface tracking unity demo app with my motox4, but instead of a camera feed I am getting a black screen. I have tried disabling all but opengles2, I have turned off multithreaded rendering. I have tried this in both 2018.4.1f1 and 2018.3.14f1, with the same results (black screen). I have tried this on my Samsung Galaxy S7 and the camera initializes as expected. My motox4 is running android P. I am using the EasyAR 3.0.1 unity sdk.

[edit] Additional info: If I choose "second camera" it works, but uses the user-facing camera (as expected). Looking into the logs I'm also seeing some low-level errors (see below)

Does anyone have any hints about where to go from here?
