I agree. from my post just above:
How about this? Turn the Apple icon on the back of the phone into a capacitive touch trackpad so I can hold my phone in one hand and scroll up and down or swipe left and right with the same hand without destabilizing my hold of the phone trying to use my thumb ineffectively. Double tap on the phone back through accessibility works great to get into App Switcher... but when in it, we need a single tap to select the app to go into. Paired with a capacitive touch Apple icon I can double tap to get into app switcher, swipe left / right or up to remove, and singe tap to select. In apps I can scroll... all with one hand. I'll take this over the camera button or a folding design any day
