They do but you have to keep in mind that in low light it compensates by opening the shutter longer, and you really need to stabilize your camera (tripod is ideal) or it will come out blurry. If you're not using a tripod, and just taking a snapshot, you can just hold still, put your arm against your body and it should come out decent.
And then what? I'm not a camera expert so I'm not sure what this means. I know how to do those things or can find it but not what it accomplishes.
In order to make sure the shutter speed the camera selects for you isn't too slow and causes blurriness, boost up your ISO to as high a value as acceptable (acceptable is subjective here).
Not every image is dictated by the same aesthetic.
