Are you using a 6 or a 6 plus? I have both and when comparing the keyboard side by side the space bar on the 6 is longer than on the plus. Because it is shorter on the plus I too press the period instead of the space bar. Feels unnatural as far as the space bar goes on the plus. But it is only when typing in safari browser text window. All other keyboards are fine. I wish they can fix that. The space bar should be set up like that on the 6.
