I have a somewhat larger phone, but I just don't type much on my phone. I only really use it for communication of logistics with people if I'm not home, or typing in addresses to navigate to, etc. Otherwise I wait until I have access to a real keyboard.

Due to my aversion of taking my electronics over international borders, I went on vacation a few years ago with a flip phone (LTE still), and found that T9 was too inconvenient for even basic logistics, so got a secondary Android phone after that.
