Hello first of all im sorry for my poor english. I need help on my note 4 rear cam. I often use my camera but recently i tried taking a picture and i saw a dust or black spot on my rear cam. I tried taking out the lens but there is still a black spot or dust. Please help

Your English is fine.
I suspect that there is dust or some other contamination somewhere inside the camera module. If it cannot be removed, a new camera module may be necessary.

Thank you sir for the information. May i ask, are there steps to remove dust inside the camera module? So i can try before deciding to replace it?
