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
I just rest the phone on my pinky, hold it with the other 3 fingers behind it, and use my thumb. When I got a bigger phone it made my pinky sore for a few days and then it got strong enough. I use both hands to type.
