Nokia 6300 Camera problem

I am using nokia 6300 in that there is a problem in camera, when i click the camera button mobile always gets hanged ?

There will be Virus problem in your handset.

It must be hardware or software problem, take to service centre he will re-install the software.

check your phone memory, sometime it hangs becuase of phone memory, you should keep atleast 4-5 mb free....
