update your phone software: seitntg about phone software update 2) install the updates right away after download completed 3) your phone will reboot === you need a Samsung acc. to update, sign up if don't have important: plug your charger while rebooting, it takes time a bit *I'm not 'Samsung Guy' btw, had the same problem since yesterday, found this page an hour ago, tried method no.3, it works and my SG Wonder's camera back to normal.. hope the same for yours :)
