I don’t understand why they need two buttons?
Another missed opportunity. The phone’s accelerometer could be used - hands-free input e.g. just by shaking your leg with the phone in your pocket.

A phone is for making voice calls !
yep, next will be a phone that prints out telegrams from texts or emails, then the circle will be complete.
