This weekend, I noticed a small black spot on every picture that I took or video that I filmed. Thinking that it was a speck of dust on top of the camera lens, I took off the back cover, removed the protective glass plate (it is easily removable as it is secured by double sided tape), and cleaned the lens. Unfortunately, as you can see from the picture, the spot remains. The spot is slightly down and to the right of center. Does anyone have any idea as to what this could be? I am thinking that it may be dust under the lens. If that is the case, any suggestions on how to clean it? I think the only way I can get under the lens would be to take screws out, but then I would void the warranty. I didn't get insurance so I don't think I can return it. But, even if I could, I don't think I want to given the shortages (esp. if it means that I'm going to get a refurbished phone). Any help/suggestions would be greatly appreciated!
