Image not showing centered while in Landscape mode

[JamesGDiaz]

Hi there.
When I change the device orientation in Android, the image im trying to show is moved downwards, as if there was a margin on top of it moving everything down. This does not happen in Portrait mode.

As a sidenote, I'm using Expo, and if I build it locally using the Expo SDK, this issue is not present, this is only present if I build an APK using Expo's online service.

Here's a link to a screenshot of the behaviour: https://imgur.com/a/nW4mdM3

This is my code:
`componentDidMount() {
console.log('SlideshowScreen shown, callerId: ${this.state.callerId}');
console.log('OrientationStatus: ${this.state.OrientationStatus}');

    //Allow rotation
    Expo.ScreenOrientation.allowAsync(Expo.ScreenOrientation.Orientation.ALL_BUT_UPSIDE_DOWN);
}

componentWillUnmount() {
    //Disallow rotation
    Expo.ScreenOrientation.allowAsync(Expo.ScreenOrientation.Orientation.PORTRAIT_UP);
}

render() {
    const dataSource = [
        [ //when the user presses Derechos Humanos
            { source: require('../assets/slides/derechos_humanos/1.jpg'), dimensions: { width: 1920, height: 1080 } },
            { source: require('../assets/slides/derechos_humanos/2.jpg'), dimensions: { width: 1920, height: 1080 } },
            { source: require('../assets/slides/derechos_humanos/3.jpg'), dimensions: { width: 1920, height: 1080 } },

        ],
        [ //when the user presses Normatividad
