Hi borkulous,
I put together a quick scene on my end to test this, but I’m seeing everything working as intended with the reflection capture and skylight in the scene.
Is this only happening in your project here, or if you create a new level do the reflection work for your mobile device?
I only tested this on a Galaxy Note 4, but it should work for all mobile devices regardless.
Let me know what you find when trying a new project and level.
