You will get the error, when you set the setting of back-camera for "Battery" or "Ground", although you don't use the back-camera.
1. long press MUTE button to return AV screen
2. press HOME button to display HOME screen
3. touch SYSTEM button
4. touch カメラ極性設定 to change the setting to "OFF"
That is the way to reset the setting.
