Looks like the iPhone X has caused an issue for Pokemon GO players. Due to the way the iPhone X's screen is set up, trainers are having trouble tossing out Curve Balls to capture Legendaries. As you can see in the image above, the iPhone X screen is actually zoomed in compared to what you see on an Android device. Seeing as how you need to swipe outside the Pokemon hit box for a Curve Ball, using one accurately is pretty difficult. There's no word on a fix for this issue just yet.
