Juz wanna to ask if my V2 got problem or is it the same as any other user here.

1) I can see a slight vignetting on the pic when i uses flash.

2) The Lcd screen seems to be very noisy (like pixel running around)... when i am shotting(record mode)
However after the i capture the image and go to the play mode , it is perfectly clear. How come ?

pls enlighten.
