Apple should have never produced a bigger phone. A phone should fit comfortably in the palm of one’s hand. That was the right idea. I use iPhone SE, which one of those small, original sized, models. (Btw, I have inherited an iPhone 6, but don’t use it as a primary phone.)
What Apple communicated by catering to the market, is that it no longer sets the design trend, but is enslaved to the whim of its users.
