Seriously. This giant phone trend is nonsense. Nonsense! I'm a 6'5" man with large hands who still swears by an SE, despite being mocked by friends and strangers whenever I pull out my "tiny phone". I had a 6S and promptly ditched it for an SE after feeling like the thing was designed to slip out of my enormous hands. That whole "reachability" feature they added when they started with this phablet obsession was basic…
There's nothing current and SE size in the Android world either (except at slow feature-phone level).
Even better, release two new phones, one in SE size but all screen so the screen's bigger, and one with SE screen size but all screen but the phone's smaller.
By my calculations you could fit a 5" screen on an "SE X". A size comparison: https://i.imgur.com/OKZiWrN.png
