That might be why Apple made it that way. No way in heck would I be able to handle the Max. It’s too big for me to use. I like the screen size but my hands are too small.
I have teeny tiny little hands, and I have no issues handling or using my Max, nor did I have issues with my previous 6s Plus and 7 Plus. You just adapt and get used to it...when I first switched from a 6 to a 6s Plus, there was a day or two of adjustment, but after that, the phone felt perfect for me. Going from the X to the XS Max has been the same - a day or two and it felt completely natural.
