Could it be that phone cameras just aren't even remotely optimized for videos being taken in the dark. I'd imagine that's when most sightings happen.

Could be but I don't understand why UFOs would only show up at night? Is that what the existing evidence shows?

Or is it just that in the dark it is much harder to identify an object and therefore there are more un-identified objects at night?
