It's not the phone size, its the reach for my fingers. I can't reach the top left corner with my thumb on these larger screens and UI/UX people keep putting the hamburger for the navigation in that spot.

I'm sure you're aware of this, but bringing it up in case you aren't. On newer Face ID models, you can swipe down on the bottom of the screen (the little grey bar) and it'll toggle the reachability feature so the top of the screen comes into the middle of the display. Basically shoving everything down.

I understand it's not ideal, but I find it a valuable feature when I must operate one handed and sometimes struggle with the same issue.

I've found that feature really difficult to trigger reliably without hitting buttons on the bottom of the screen if they're there. Maybe it's just because I'm on a 13 mini, and before that a 12 mini. But if an app has a bottom navigation bar, I've found it absolutely impossible to trigger reachability without also hitting the bottom navigation.

I did also set up an accessibility feature where you can map a handful of actions to a double or triple tap on the back of the glass, and I mapped double-tap to trigger Reachability. But it's not super fast and overall a bit of a downgrade from the double capacitive TouchID tap on older models.

It's already almost impossible to reach the top of the screen. "Only a few mm taller" is nothing but worse.
