I did forget about the camera bump, but I don't believe the numbers work out that it's adding .15" to the thickness of the phone on its own. I had a recent chance to compare the SE (2016) to my 13 Mini (my mother still has the original SE but is likely to upgrade soon, I was recommending the mini since, other than the home button, it mostly met her needs and would provide a better display for her aging eyes) and it's definitely not 50% thicker at any point. That would have been quite noticeable.
