Why do all my selfie pics come out like negatives?

[AC Question]

Why are all my selfie pics come out like negatives?

It only started today. It is only in the selfie mode but not in the wide selfie or other modes.

I am assuming that you have a Galaxy S7, correct?

This is a bug in Samsung's processing of pictures from the front facing camera.... I have no idea if it is fixed or not in the current patch level. But it popped up on my wife's S7 a couple of times and a reboot cleared it.
