How do I fix my negative pictures?

[AC Question]

I was taking some pictures and then all of a sudden every other picture I take is almost negative looking. I'll take 1 picture that's fine and the very next one is negative and then fine then negative. I have the S6 edge

Welcome to Android Central! Do they appear negative regardless of where you view them? In other words, if you copy the photo to your computer, or upload it to Google Photos, is it still negative?
