A Photo I Have No Memory Of

Earlier today, I was looking through my smartphone's photo folder and found a picture I have absolutely no memory of taking. It's a strange image: a flat surface of shocking pink with some kind of white mark left on it. I can't tell what it is, but to me, it looks like a white handprint…. The photo was apparently taken recently when I was shopping at a convenience store. I remember taking my phone out of my pocket, and for some reason, the camera just turned on by itself (though I might have just messed up the controls). But the image itself is baffling. Would it be okay to post it in the comments with a bit of a buffer? ... It doesn't look too scary, so I'll post it (sorry if anyone is sensitive to this kind of thing).
