check the camera settings in your mobile, there is option of effective settings if the settings are ok, than contact service center

I would try to resend the settings to my device via the sonyericsson website. Just go to the support section of thier website. Also, if that doesnt work try a master reset as that sometime help. If that doesnt work, try updating the firmware by again going to the support part of the sony ericsson site downloading the update tool. Then just run the sony upadate process and it will upadate your phones software. If again that doesnt work go to your local service center and have it flashed over there. If you dont have a local service center in your area, check my profile and im sure we can help you.
