What network / country are you on? Are you rooted? Have you had the latest 14.4...update? The camera was always very buggy for me too, until this last update. I would like yourself by the sounds, have to wait several seconds for the camera to open after selecting it, and after having the app open for a while would suddenly get the "Camera has stopped working" message, phone would run hot with it open sometimes etc. However with the latest update, camera opens instantly and haven't had any running problems as yet. Did you have the phone from JB and not have issues with the camera? Have you asked Sony about it in case it is a manufacturer fault? I know there have been lots of people with bugs in the camera and people kept getting certain things fixed with updates where others didn't, I have had problems right through until now.
