Answer 1

Only a concept, but I'd try following:

const Dimensions = require('Dimensions');
const Viewport = Dimensions.get('window');

const IPHONE6_WIDTH = 750; // check this, since I'm not sure about iPhone 6 width

class YourComponent extends React.Component {
  constructor(props) {
    super(props);
  }

  getFontSize() {
    return ({
      fontSize: ((Viewport.width * Viewport.scale) === IPHONE6_WIDTH) ? 14 : 16
    });
  }

  render() {
