No worries.
I tried the project and launched to the Galaxy Note 4 without any issue. Here is a screenshot directly from the device with your project
As you can see I’m getting the reflections in the scene.
Looking at the project settings there doesn’t appear to be anything that should limit it from working. Double check that your project settings > Target Platform
is using Maximum Quality and that under the Project Settings > Rendering > Mobile HDR is enabled. without this you will get lower quality settings and lose some rendering capability intended for use with low end devices.
