Hi, I am not sure what is the problem with this iPhone I have owned several iPhone not the x is by far the most problematic phone mine has been replaced twice and then last night I get this green line on the screen visibility is very difficult
iPhone X, iOS 12
We can't diagnose that kind of issue remotely, sorry, even if it sounds like a hardware (screen) failure.
Make an appointment at an Apple Store or Authorized Service Provider and have your device inspected. After checking it, they'll give you all the available options: Apple–LocationSelector
