I can see Apple making a bigger screen iPhone than the max now if that is what the market research says. I can fit my old iPad mini in my pockets in my slacks and jeans just fine so the new IPad minis could be the new iPhones and people would buy them.
I got the iPhone X last year and got used to the screen just fine but I always thought it was to big for my hands to type one handed comfortably so this year I “upgraded” my line to the iPhone 8. I was really looking at that iPhone SE but the iPhone 8 will be supported longer than the iPhone SE. i just wanted a smaller screen and a one handed phone. Kudos to people who can one hand the iPhone XS Max one handed.
