RTL is forced in RTL devices

In manifest.xml file add android:supportsRtl="false" to your application tag

I managed to fix this by adding to MainApplication.java:

import com.facebook.react.modules.i18nmanager.I18nUtil;

public class MainApplication extends Application implements ReactApplication {
    @Override
    public void onCreate() {
        super.onCreate();

        // FORCE LTR
        I18nUtil sharedI18nUtilInstance = I18nUtil.getInstance();
        sharedI18nUtilInstance.allowRTL(getApplicationContext(), false);
        ....
    }
}
