Change-Id: I2995e914d622e9865101ef16e3b280c65371a252
Root cause: User feels confused because the particular screen doesn't have a back button but at that moment of the setup flow the regular UI gestures didn't even work.
Solution: Add a done button to the vision settings pages for clearer navigation.
