I think you are probably using it wrong as you heard it is "Normal" /sI'm insanely obsessive compulsive about build quality and defects. My iPhone X has a very audible cracking / popping sound when I press with some force on the center of the screen. Simply taking my case on and off causes it as well. I've read posts about others having the same issue. I had a genius inspect it and was told it was normal (of course it isn't) and he couldn't hear it (of course he couldn't). My screen is flawless so I kept it. I've returned, exchanged, and sold in total about 10 iPhone X units. I have never in my life seen such variance in quality and unacceptable screen defects. Not defending Android at all. It took three Pixel 2 XLs before I got a flawless one. But the iPhone X, to me, has been a hot mess of a phone.
Anyway, I agree with you nothing is perfect and there will always be issues when it comes to hardware & software, sometimes more than what we want. Still trying to forget the Pixel 2 issues...
