But does it actually? Because if it's just a belief, nothing prevents the same belief from occurring with the 3D Touch home button. I guess it's going to be a feedback loop because obviously there wouldn't be reports of failures if nobody uses the physical button, but assuming normal usage, does the button fail frequently enough to be a concern? I think the west is a clear proof that this is not the case (unless something in Asia is breaking the buttons - climate maybe?).
