True, but the camera has been the principal or at least one of the principal year-to-year marketing points, I mean technological improvementsand there are limits to what can be done/improved without adding some physical bulk.
The ‘bump’ adds barely a millimeter to the ‘bulk’ of iPhone - bulk that could be utilized to include a thicker battery, for example.
Which wouldn’t be an issue, if someone didn’t have an obsession with perceived thinness.
