Dust in lens?
I just noticed that my SGS4 has some small black spots in the camera. It's just in the main camera, the front camera is OK. They appear in the top quarter of the image.
I already tried cleaning the lens with a micro-fibre cloth but it did nothing.
At first I thought it could be dust beneath the lens but one thing strikes me as odd, these dots remain the same while I change focus from close to far. Shouldn't they change shape while focus distance changes if it was dust? If I zoom in the camera the spots disappear.
I attached a crop of a photo from my phone. Do you think this is dust? What can I do to solve it?
