My friend has the Samsung Galaxy S7 Edge for about 2 months and her front facing camera is turning all her pictures a red negative effect on it. I will show an example the other camera settings work perfectly fine, it's just the front facing camera with the selfie function. The video front facing camera works fine also. She is going to take it back to the shop but she said her old phone, a Note 4, had a similar problem. Occasionally when she is using her front facing camera, it'd go to the red negative effect. I hope I can get a reasonable answer on why this is happening other than her supernatural belief of ghosts. I'll include another picture that is using her back camera.
