@stakek Thanks for sharing these materials.
Based on the devices you are building to and the fact that their GPUs are both Mali-based architecture, you may be experiencing the same issue as the ones found here and here relating to the graphics hardware in some Android devices, and their inability to support the compute shaders found in the Depthkit Unity SDK. This is one of the reasons that Android support is listed as experimental in our Unity platform support documentation.
Do you have any Adreno-based devices to test on?
