I've ranted about this to friends but they didn't get it. Glad to know I'm not alone on this!
Also the audio jack on the bottom: can no longer use headphones and prop the phone up on a desk when using FaceTime (which is surely a common use-case)
It's not just the screen. The actual physical phone has to come out of my pocket upside down if the headphone jack is on the top. The volume keys are on the wrong side; if you have a home button or fingerprint reader, it's flipped upside down.
I wasn't trying to make a massive deal about it, for what it's worth. Every phone I've had for probably 8 years has had the jack on the top instead of the bottom where I'd want it. It's fine. I was just chiming in to say there are legitimate reasons why it's not necessarily obvious that there's a correct answer.
