title: Optimise android apps for phones with the new ratio's like the S8 (18.5:9)?
body: <p>Just got the new S8 and I'm trying to update my android (react-native) apps because there is a black bar on top of the screen because of the app scaling of the ratio 37:18 / 18.5:9. Adding fixed height and width to the app doesn't work I still get that black bar in top. Removing the statusbar seems like removing a bit on top and at the bottom. </p>
  
  <p>As an example I created a new react-native app but a native Android has the same problems.</p>
