Wasn’t there a Google phone that naturally placed it on the center back? I don’t do it as much these days, but grabbing the phone with my thumb and unlocking it as I pull it out of my pocket is still a semi natural occurrence. It should be pretty possible to achieve the same with the index finger and I believe whichever Google phone did this managed to pull it off pretty well
