Blemish smudge mark on photos

[Rhodes]

I am after any hints or tips of how I can rectify a smudge mark that has developed on my camera causing imperfections on my photos. Has anyone else had this issue? I've not long purchased the Samsung A51.

@Rhodes: Can you try wiping the rear camera lenses with a clean, dry microfibre cloth to see if this helps? If this isn't applicable, please can you provide further details of the issue, including the position of the smudge, and which Camera Mode you're using?

The first photo is a screen shot before it's taken and the second is the actual photos. It's the rear camera, it appears to be on the main one as not evident on the 2nd, 3rd or 4th camera.
