Not sure how this could even be possible but both my cameras now have mositure marks on the front screens. Neither camera has ever touched an ounce of water. I have not been able to use my camera over the last month because I had to get new SD cards, so the cameras have been sitting inside my room. Now that I got new cards, I used the camera today and noticed the marks. The marks were never there before (with the old cards) and they only show up when the camera is in direct sunlight and recording. I recorded myself with both cameras inside the car and the marks did not appear. Anybody have a clue what has happened?

Hello there united by water. I am sorry for the trouble this has caused and thank you for reaching out. In some rare circumstances, condensation behind the DJI Osmo Action’s front screen may occur when the device starts to heat up during normal operation. This does not affect the product performance and the fog will disappear naturally without leaving any marks. To eliminate the fog quickly, you can place the product in a dry area. When using DJI Osmo Action underwater, please make sure the battery cap is locked properly with dry hands. Thanks for your understanding.

What about on the lens? I thought I remembered that happening as well. I should have taken a picture of it when it happened. I will try and see if I can replicate it.
