Issue Description

Steps to Reproduce / Code Snippets / Screenshots

componentDidMount() {
BackHandler.addEventListener('hardwareBackPress', this.handleBackPress);
}

componentWillUnmount() {
BackHandler.removeEventListener('hardwareBackPress', this.handleBackPress);
}

handleBackPress() {
Alert.alert('Exit', 'Are you sure?', [
{
text: 'No',
style: 'cancel'
},
{
text: 'Yes',
onPress: () => BackHandler.exitApp()
}
], {
cancelable: false
});
return true;
}

Try this, to exit the app on exception.

    onHardwareBackPress = async () => {
        try {
            const { componentId } = this.props;
            await Navigation.pop(componentId);
            return true;
        } catch (e) {
            BackHandler.exitApp();
            return false;
        }
    };

had the same issue with LightBox
I change onBackhPressed() method.

@Override public void onBackPressed() {
        if (cancelable) {
           // hide();
        }
    }

in your case you should do the same for Modal class.

@Override
    public void onBackPressed() {
        if (!layout.onBackPressed()) {
           // super.onBackPressed();
        }
    }
