My kids was taking photos of me and my wife and in one of them I appeared double on each side of my wife. Would you help me understand how it happened. We used a LG phone. Thank you]1
I am quite sure that the answer is here: Is it possible to get a double exposure with a digital camera?
Your wife's camera phone has a feature called "HDR", where it takes two pictures in quick succession and combines them, in order to better capture both bright and dark areas. It happens quickly, but if the subject (here, it's you) moves quickly, you'll get this kind of doubled image. This also explains the blurred representation of your wife.
