Browser Lag? weird creak?

---

I notice that on my lumia 900 there is some weird creak on the side of the search button. Every time i press the search button it creaks. In the browser the pinch the zoom originally lagged, but now it doesn't but still sometimes it does. Do any of you have this problem. The browser sometimes will lag with pinch to zoom from time to time and from different new websites. Anyone else experiencing this?????
