In the iPhone XS the snapchat camera is really grainy and zoomed in

Hello, a few weeks ago i bought an Iphone XS and my favorite app is called snapchat, just going from Iphone 7 to Iphone XS was a big difference in the snapchat quality? In the Iphone XS the snapchat camera is really grainy and zoomed in. Can you please fix it soon?
