Hi, if when you try to take a picture, the screen displays what the camera is looking at to start with but only returns to the main menu when you actually press the button to take a picture then that is a software problem, if you goto the sony erricson website and download 2 pieces of software, 1, the application suite for your mobile, followed by 2, the sony ericson update software, you can get these from www.sonyericsson.com , once downloaded install the application suite and then plug in your mobile to you pc using the usb lead for your phone, once the pc has setup your phone , unplug the phone and then install the update software then follow the on screen instructions!
Hope this helps.
