I'm still on a Sony XZ1 Compact. The phone's screen is only 4.6" large but man oh man, does it easily slip into ALL of my pants front pocket with ease and without looking like an idiot having something stuffed so large in there as if to compensate or distract from something else.
I bought myself a Samsung Galaxy S10e as a replacement, but haven't even opened it yet since I'm far too used to my Sony. I don't wanna part with it; it does so many things right, like TWO front facing speakers, dedicate shutter release button for photos, power button also acts as fingerprint reader, etc. Amazing how Sony did all these things in such a small package while including a headphone jack and here's Apple desperately trying to make phones as big as possible.
