    Any particles inside the cavity between the protection window and lens have most probably been trapped there in the assembly phase at a Nokia factory. Unauthorized disassembling of the product can also be the root of the problem. However, in most cases it should be possible to remove the particle(s) by using clean compressed air.

    If possible, compare the image to another image of the same scene, taken with a different device. Note that the reference device has to be a similar Nokia phone. There are several conditions in which AF operation is challenging for the camera module, i.e. failing from time to time.
