I have the same problem as here:
https://stackoverflow.com/questions/48361898/how-to-remove-internal-shadow-of-react-native-stacknavigator-when-using-safearea
I am not sure if we can use the cardStyle fix with react-native-router-flux.
Tell us which versions you are using:
"react-native-router-flux": "^4.0.0-beta.27",
"react-native": "0.52.0",
No shadow on blank statusbar
It shows a shadow

<Scene
key="Main"
component={Main}
initial
hideNavBar
panHandlers={null}
/>
Try this:
<Router getSceneStyle={() => ({
elevation: 0,
shadowOpacity: 0,
borderBottomWidth: 0,
})}
