Phones have been doing this for a LONG time, if you had a oneplus 7 pro (released may 2019) and took it into an extremely dark area, like where your eyes can't see anything at all, and take a 'night mode' photo, it asks you to hold it steady for about 4-5 seconds and is clearly taking a series of photos with long exposure time. Then it stacks them and uses data from the sensor of hand movement jitter to deblur.
The result when done outdoors (like, standing in a dark forest at midnight) will be a photo where you can actually see what's around you, and details show up as if it was a brightly full moon lit night.
