I bought and just received a used iPhone13. The battery was 100% so I was quite keen.

Does anyone know why this could have a moisture cloud in the lens section? Is it nothing or has it been dropped in deep water? Will it clear with some silicon or rice?

Pictures are fine but I’m concerned there is water damage elsewhere which has yet to present itself? I’ve not left a review and just literally received it. Any help would be appreciated, thanks.
