That's what I've been saying for years. My last phone was a Galaxy Nexus, and my current is a Nexus 5. The change from 4.65" to 5", along with less-rounded edges, meant that the new phone was really a mixed blessing for me. I'd really prefer something that fits in my pocket without me noticing and that I don't need 2 hands to be comfortable using. People still think I'm crazy when I tell them that 5" is too large for a really usable phone.

Depends how big your hands are. I have a 5.0" inch and can use the whole screen no problem one handed no problem. 4.5-4.7" would exclusively be a downgrade for me.

It's not just how it feels in your hand, it's how easy it is to tuck away in a pocket. Unless you carry a purse or wear some sort of belt clip, a phone can get quite annoying to tote around.

I got used to Nexus 6P (5.7") quite quickly, and I don't wear purses or belt clips. It did feel a little uncomfortable at the beginning.
