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 generally walk, and I don’t own any running shorts, so that’s not really a problem, but if I ever wore running shorts that’d probably be an issue I guess. Don’t they have some sort of phone straps you can attach your phone to your arm or something? It’d probably look almost comical strapped to an arm, but that might fit better than I’d imagine it would in running shorts.
