Decals don't show in mobile build?

I tried building the Decals level from Content Samples and none of the decals/textures showed up in the mobile build. Is this the expected behavior?

Hi Ian. I don’t believe we support decals on mobile, but I’ve requested more information from our platform team for verification.

Yes, decals are not supported on mobile.

but ,decals are supported on tablet computers,Samsung T800 S8 is supported,So, I don’t know if it’s Resulting the phone Edition?
