Dirt in camera lens?

[Android Central Question]

My rear camera images have dark circular patches on them.

Yes, that could be some kind of internal contamination.

Hi, I made the opening post. How do I fix it? I'd like to remove the glass, clean it and put it back. All the how tos on the web are for cracked glass. I need to remove it without breaking it.

Welcome as a new member.

It depends on where the contamination is. If it’s dust or water condensation drops anywhere other than behind the front glass, it would really require a replacement camera module.

How you’d get at the front glass to clean it, if that’s where the trouble is, would depend on the phone.

It's a Galaxy s7

Okay, I’ll move the thread to that forum.

If the dirt is behind the glass or behind the lens, it's not going to show up as nice circles - there's nothing to focus them on the sensor. (Anything closer that a foot would show up as darkening the whole picture, as if you had closed the iris down.) I suspect a bad sensor. If the phone is out of warranty, you'll probably have to pay to get the camera module replaced.
