Unity Terrain texture issue on android device

Hello.

i have some problems with terrain textures it becoming pink when i test it on android. i have tried to remove and change texture but still pink but only on terrain ground textures. i have no problem with any pther 3D object texture.

im using Unity 5.1.0f3 and bluestacks app player as android device for test and not using any texture compression.

Magenta means something is wrong with the shader. Try setting the terrain’s material to use the Built in Legacy Diffuse.
