Answer 1

found it myself ;) adding:

  left: null,

disable the default back button.

const MainStack = StackNavigator({
  Login: {
    screen: Login,
    navigationOptions: {
      title: "Login",
      header: {
        visible: false,
      },
    },
  },
  FirstPage: {
    screen: FirstPage,
    navigationOptions: {
      title: "FirstPage",
      header: {
        left: null,
      }
    },
  },
