Hi guys, I have an iphone 6 with a cracked screen. Still works ok. Now, on the upper right corner, where the screen cover is missing, is a small felt-like black/grey pad that has been affixed but is now starting to loosen, exposing the metal underneath. Should this concern me? picture of the thing I’m asking about:

That is the camera. If the screen is broken in that corner either way you don’t really need that felt piece. Either way you should avoid water sand or anything from going in to that hole. I recommend you fix it.
