Several years ago I had this same issue occur in Facebook Messenger. I was using a pretty slow outdated device even for the time. I went to take a picture to send with the in-app camera. I actually pressed send before the picture rendered on my screen and somehow what was sent was not the picture I took, but a picture of some man's forehead who neither of us had ever seen before. It seemed like a pretty huge bug that could be a serious problem if anyone could reliably recreate it, which I could not. I went about trying to report it but ran into so many problems and broken links searching for Facebook's bug reporting that I gave up. Here's hoping it's been fixed, though I haven't used Messenger for at least a few years now anyway.
