Default [Q] Camera focuses only left in any camera app & right side appears blurred

I own a Micromax canvas a250 which is about 3 months old. The back camera quality was average during the first use, but the front can was totally brilliant. I updated it to stock ROM v3,
after the update I begin to notice that in any camera app(even in 3rd party apps) only the left side is focused manually or automatically & the right side is blurred even after manual or auto focussing. Does any of you experience this? Any one have suggestions?
