Rendering issues on Adreno 610 and 612

I keep receiving reports from users saying the shaders look all black, it seem to happen only on adreno 610 and 612 (Samsung A70 and Xiaomi redmi note 8).

We’re using Linear color space, with vulkan and Opengles 3 and lightmap quality set to High (ASTC).

Unity 2019.4.16f1 LTS

Has anyone experienced this issue?

After further investigation its seems to happen only on Vulkan.
Opengl works fine.

Should be fixed

(It’s now fixed in the latest versions of Unity (2020.2.2f1, 2021.2.0a1))
