Simple Material - Huge difference on Mobile Preview

I am developing an iOS app. I have setup a very simple material, but there is a huge difference on how it looks on Desktop preview vs. Mobile Preview. On mobile preview I don’t get the reflections!

In the material I have “Fully Rough” disabled. Enabling has no difference.

I have a sphere reflection capture in my scene.

I use UE 4.7.2

Please have a look at the attached images.
