Why did 2 photos merge as one in my gallery?

[Android Central Question]

So i was scrolling through my photos and saw that one looked "glitched" with pink and greens bars on the bottom and a fuzzy image of some table art i took with no color, just outlines, on top of the original photo that was also grainy but colored of me long boarding, just backgrounding the outlined art. I have images to show if anyone would like to help. It happened with my galaxy s7 edge and why i bring it up is because it happened to my friend on his google pixel 2 so i was wondering why it could be a possibility to happen on different phones if it is a glitch, also i want to know the cause. Thank you

Welcome to Android Central! It'd help to see that photo, but you'll have to register on this forum first. https://forums.androidcentral.com/ask-question/409154-join-android-central-community.html.

Are you using the Google Photos app as a gallery, or the stock Samsung Gallery app? If you use a file manager app, can you find the original photo files in the /DCIM/Camera directory without the corruption?
