Do you cave and use both hands? Do you take the chance and try to use them one-handed when more actively using them? Or do you ultimately submit and get an accessory to kinda help, at least with keeping a hold of them?

a few other answers:
just use both hands, get an accessory, and/or balance on pinky and develop the toughest pinky imaginable
bonus:
find some smol phone you like and savor it for as long as it works
S23 Ultra (6.4"x3"), the spigen thin fit case is pretty good for grip. It allows me to use my fingers in the back as a pivot to rotate the phone and move it around to be able to bring my thumb to the top. When texting i often use swipe with the thumb which allows me to write fast, unless i know i’ll be writing alot, then i switch to two handed.
