This is a wonderful case, it does make your phone feel like a brick... But that's why you are looking at this case, so you know it's as projected as if the phone was a brick. I do not has the bad sound quality many say the case gives the phone. Calls are great and the touch screen is still fine. Only reason why I put a four star is because the back and menu buttons are a little hard to get to.
No, if you were to watch the installation video it would have answered that question for you. Armored cases are designed for the phone with 'no' extra addons. This may(will) add to the thickness of the phone and jeopardizing the waterproof seal.
