I mean I'm more concerned about things like my future than whether or not my sp will lift one day.To some it's not. Mine was about 1/16th of an inch with every one that I tried. Also those gaps will become dust traps causing the sp to begin lifting on it's own. That was sp try number one for me.
Actually, I'm referring to all the S/P's that are made for the iPhone 6 that claim are compatible with the 6S but all suffer from the dreaded "halo" effect.If you are talking about the .00000001 MM space on each side...it's really not a big deal. At all.
