As far as physical size goes, I use the Palm Phone: https://en.wikipedia.org/wiki/Palm_(companion) https://en.wikipedia.org/wiki/Palm_(companion) https://palm.com/cdn/shop/products/Palm_inHand_1024x1024_2x_de317bc2-cfcd-4ef7-be8f-4daf55d69e7d_1200x1200.jpg?v=1618426329 https://palm.com/cdn/shop/products/Palm_inHand_1024x1024_2x_... Despite its marketing, I do not use it as a companion phone, it is my sole mobile device. It's an Android phone with a 3.3" 720p screen. It's very light (2.2 oz. / 62.5g) and fits in my pocket easily. I can also effortlessly swipe-type on the bottom of my screen and swipe-gesture from the top of my screen with just one hand. It doesn't have that irritating yellow/green light that tells me when I've missed notifications, although I have most notifications disabled, including voicemails. To my delight, even that presidential alert test did not seem to reach my phone. I also have a great excuse for not installing corporate software on my phone (literally unsupported in many cases). But it is a device from 2018 and sadly they do not seem to be interested in making a new one. I don't need it to do anything it didn't do when I first got it, but sadly, software companies specialize in making consumer UIs slower and updates in general are no longer an optional thing, so they have no incentive to improve. Even loading my texts, answering my phone, and checking my email is becoming noticeably slower (and it is not an old battery issue as I have replaced a broken Palm phone within the last 12 months). I'm not sure what I'll replace it with when it becomes impossible to use. The Unihertz form factors are strictly worse, smaller screens with bigger phones. Hoping someone comes up with something similar within a few years.
