Re: I'd happily own a phone
I rarely if ever use my front-facing camera, but I would never try and sell a phone without one.
Previous responses to the same design intent of maximising the screen area include:
Mi Mix. Camera placed on lower bezel.
LG V20. Discrete half-width display placed alongside front-facing camera - don't know if it's 'always on' for showing the time etc, but possible power savings if so.
Essential Phone. Notch in screen, smaller than iPhone X's.
PS, yeah, I read of a Samsung Galaxy that would attempt to scroll down web pages based on the user's eye movements... don't know how well it worked.
