Rendering issue with Galaxy S7 Exynos 8890

I have create a simple level consist only couple cube. Each cube with the default material. However, when it render on my S7 (International version), all the cube is render as black, it seems the lighting is not working at all. I try to install my test on other Phone (eg Nexus 6), everything rendering correctly, and the cube in the level have correct lighting. Is there any issue with the Exynos 8890 version of S7? Anyone experience similar issue? Thanks!

Look for a solution here if mine does not work[][2]

Hi, I believe this is caused by a precision difference with vector normalization on the Galaxy S7.
We made a change for 4.11 which fixes this problem.

Could you try with 4.11?

The fix is here if you want to try applying it to 4.10. It’s only shader source so it doesn’t require a recompile.
