Another thing I noticed using my 8 non plus which I like. When I hold the 8 on my pinky shelf 1 handed I guess the the bezel where the home button is more convenient than a swipe to get to reachability or back to home. A double tap on home where the home button is doesn’t take much adjusting vs having to stretch uncomfortably and insecurely to swipe on the edge of the X. I found this difficult on the X when I had an Otterbox Symmetry case on because of the lip / lay on the table.
So in my experience actually the space or bezel where the home button is helps with ergonomically navigating the device easier believe it or not.
Now if the X could put the main navigating when holding the phone on pinky shelf where it’s convenient for my thumb to move without it being uncomfortable and insecure it would work. Like getting access to the Control Center or battery % which I like to look at through the day.
Yea the chassis could work but where the gestures to get to stuff isn’t conveniently placed for 1 hand use IN a case when you’re a pinky shelf-er.
