Objects not rendered on iPad 1 (SOLVED)

Target Platforms Mobile

hi, I am beginner and facing very weird problem that objects (materials?) are not rendered properly on older iPad (normals are flipped somehow?) let me show you screenshots:

This is how it looks like on iPad 1:

And this is how it should look like and actually looks on iPad Air:
2286107--153593--image.jpg
2286107--153593--image.jpg1536×1730 162 KB

Any ideas ?

My scene contain one directional light with hard shadows enabled.
