Depending on your phone in my case pixel 9. Your phone might have a night shot setting. This allows the shutter (eye ball of the camera) to stay open longer taking in more light. In this photo the shutter stayed open for 1/10 of a second this is why the trucks tail lights leave that laser looking glow behind it. Imagine in 1/10 of a second your camera is observing and recording all the light that it sees in that moment.
