Bit Errors - Nokia NHL-2NA Series Troubleshooting Instructions

Bit errors

Bit errors are defects in image caused by data transmission error between camera and
phone baseband. This type of error is expected to be rare since usually missing bits will
cause a hardware failure message. Bit errors can be typically seen in images taken of any
object, and they should be most visible in full VGA resolution images. Viewfinder images
may not contain the errors at all due to lower bit rate used in this mode. A good practice
is to use uniform white test target.
The errors will be clearly visible as colorful sharp dots or lines in camera VGA images.
Typically this is a contact problem between the camera module and LG4. Check camera
assembly and spring connector contacts.
