@Blapi could you look on this android issue?

Ok so after investigated on this, the point is that on NavBar.js

  if (!state.backButtonImage) {
    return (
      <HeaderBackButton
        onPress={onPress}
        title={state.backTitle}
        titleStyle={textButtonStyle}
        tintColor={tintColor}
        truncatedTitle={state.truncatedTitle}
      />
    );
  }

When you don't pass a backButtonImage, it should return this Component from react-navigation but this component is returning an Image with the back-arrow, so the backTitle is ignored.

So 2 solutions, either we implement an other Component which will be an other HeaderBackButton with the result we wish (requiring a PR), or either passing a fake path as backButtonImage, so the backTitle will be displayed but with a warning (quick crappy fix).
