That is why the cleanness of the protection window should always be checked and the window should be
wiped clean with a suitable cloth.
Bit Errors
Bit errors are defects in image caused by data transmission error between camera and phone baseband or
inside camera module. Bit errors can be typically seen in images taken of any object, and they should be most
visible in full resolution video images.
A good practice is to use uniform white test target when analyzing this kind of errors. The errors will be
clearly visible as colorful sharp dots or lines in camera images. See figure below.
One type of bit error is lack of bit depth. In that case image is almost totally black under normal conditions
sensing something only under very high illumination. Typically this is a contact problem between the camera
module and phone main PWB. Check camera assembly and connector contacts. If fault is in the camera module
typically bit error is visible only when using some specific video resolution.
