Blit() on Android device outputs black screen

Hi,
I’m testing my game on Android device - Samsung gt-s7582 and I have problem using Image effects. When I turn them off, I’m getting expected output - without effects. When I turn effects on camera on, I get only black screen. Even when I simplify blit code as much as possible, not using any custom shaders, blit outputs black screen:

void OnRenderImage (RenderTexture source, RenderTexture destination) {
Graphics.Blit(source, destination);
}

This causes black screen. Is this known bug or am I missing something?

I’ve found out more about my problems.
I identified two cases:
1.) I force API to OPENGLES3.0 - blitting works, but none of my custom shaders work…
2.) I force API to OPENGLES2.0 - blitting doesn’t work, but my custom shaders do work
Have anyone had similar problem? Thanks for any kind of advice.
