do i have a faulty device? (home button issue)

[raptorz]

so i received a new device today as the other one was replaced cos of some issues,anyway, this unit is way better than the other one except for one annoying thing ,the home button, well it's not so loose like the old one and doesn't make the click sound at one side only like the other one did and generally it's better yeah,but i was examining the home button and i noticed 2 small shiny metal parts deep in the gap that surrounds the button, here it's

there's another one on the left side but it doesn't appear in this pic, well i know that u guys will think it's reflection but trust me it's not!,i watched some teardown videos and those parts don't even exist!, the home button doesn't have those part on top of it! so what am i seeing? my only concern is the waterproofness

When you say new.. was it in retail box or was it a refurbished in a white card wrapper?
