The camera on my phone was recently upgraded by Google with a clever software trick. It can shoot video in extremely low light conditions. It takes a super-long exposure, and overlays multiple exposures while adjusting for camera movement using the phone's gyro sensors to provide image stabilization. It also somehow adjusts for elements of the picture that might be moving, perhaps by separately tracking that one element in the photo and removing it's movement also.
This article gives a really good side-by-side comparison of what the night-sight can do.
There software even uses artificial intelligence to figure out the white balance.
This page illustrates what it looks like on your phone as you shoot, and gives an example of how it removes motion.
I took this shot in a dark parking lot with minimal overhead lighting.
