Hi All I was just taking some photos of items for work when I noticed on a white wall that there was a weird smudge on my camera. The smudge is not on the screen for any other app. I tried wiping the camera lens, but I have the same problem. I restarted the phone as well, same issue. Does anyone know what this is and a possible remedy? I was starting to think I had a good phone as there were no scratches or other issues people have been having. Thanks in advance, some sample photos are attached.
