I have the same problem, had it with my S22U as well. I've found the Spigen Cryo Armour to be quite gentle on the pinkie. I also picked up the Samsung case with the silicone strap which I've used a lot more then I expected to give my pinkie a break.Any cases that don't have a sharp USB c cut out? May sound silly but the way I hold the phone it cuts into my pinkie and actually hurts after a few minutes lol. Running naked now but I need protection
