Bug Certain Android devices render 3d objects incorrectly on ARCORE

Hi everyone,
We use ARFoundation and have built the the product to an apk. On certain devices the 3D game objects that are being rendered in the ARcore plane do not render nicely. Its as if the textures are not compressed right or that the shader is broken...

These carrots are not rendered correctly( doesnt look like a carrot, just a solid color:

here on another device it is rendered correctly ( you can see different colors on the carrots, aka they look dryed out... which is correct):

We have tried ETC compression with no success.
It looks great on a Samsung A8 but a Samsung S8 shows the problem as does a Goolge Pixel3

Thanks for any insight!

 

What shader are you using? are you on the standard pipeline or URP?
