It seems as though my kickstand almost needs some lubricant. It sticks somewhat over halfway open, and needs a push to fully open, as well as close. My question: what oil/lubricant would be safe enough to use without eating away the paint and finish on the phone? (I.E. WE-40 is definitely out). It's just annoying because I use it alot to prop up the phone and keep it off its back, and camera lens at that. It's annoying hearing it squeaking every time it opens and closes.
