I had a Samsung Galaxy S4, I think? Back when they still had removable batteries... Anyways, the phone was too tall to fit comfortably in my pocket, would dig into my hip and end up partially under my seat belt while driving. Eventually, the damn thing ended up bent, about inch from the top of the screen. Glass didn't break or crack, but the phone sorta looked like a bendy straw, mostly straightened if you looked at it on edge from the side. Still worked perfectly fine for quite a while with that bend, though. Definitely was too thin for my casual use.

Id prefer a slightly thicker phone with a slightly smaller screen, the better to actually fit in my pants pocket.
