Unity 5 Android Realtime Shadow Problem

When I build and play:

When camera look the ground:

Camera up:

And shadows (hard) downgrading FPS from 60-63 to 20 (in simple quality).

My settings:

My Unity version: 5.1.1f (same in 5.0.2f and 5.0.1f)

Someone help me please? I want to use shadows on my car. Sorry for my English :slight_smile:
