This. I'll explain. the higher the ISO the faster the shutter speed at the expense of photo quality. in traditional film cameras higher speed films (ISO) came out very grainy and loss of detail. It's used a lot in dark, low light situations because as you know the slower the shutter speed, the more chance of blur.
image stabilization in smartphones has at least some to do with shortening that shutter speed by ramping up the ISO, leading to loss of detail. aperture / shutter speed / iso are the three things that are correlated, our cameras have a set aperture. when you take pics outdoors on a bright day, the shutter doesn't have to be open long, and the ISO is taken down to 100, so that is why you have amazing crisp clear pictures.
at night, take of image stabilization, set the ISO to 100-200-400, and have a VERY steady hand. when you try all 3 ISO levels, you'll notice it will take longer for the shutter to close, however if you have a tripod or set it on a table, your picture will look very clear. clearer than iso 400, 800, etc.
the benefit is at higher ISO, in low light settings the shutter will be faster so less chance of blur
