question about refurb

[blackmagic352]

i just got a refurb from sprint saturday. im not sure but it seems odd. the buttons of the face are not flush with the screen. if i take may finger nail and run it down the screen(top of phone to bottom), it seems that if i tried i could lift up the buttons. first question are the buttons suppose to be flush? second should i take it in to sprint store or call?

im pretty sure the store is going to say "this is how it is suppsoe to be"
thanks
