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
Get a Z flip. Foldables are the current answer of the industry to your pledge.
EDIT: Just noticed the door sign comment. LOL, we are legally required to put a sign to tell people how to open doors in every single public door. Yet people get it wrong all the time. That’s 100% not a design problem, there’s very little to change in door design that affect usability like that. Like, literally has handle/knob or doesn’t have handle.
