Cool i finally discovered that the volume rocker is a physical camera button.

The camera seems to take fuzzy photos in low light or from zoomed in. Is there some setting to improve that

That's rather normal behavior unfortunately.

In low light the camera needs to increase its light sensitivity by raising the ISO which in turn introduces digital noise. This makes the image appear grainy or fuzzy. The camera should have a night mode which would help with this, but it doesn't completely eliminate the problem.

When zooming if you go beyond 2X the phone is digitally zooming which in effect is just cropping the image resulting in fewer pixels and less detail. The telephoto lens for 2x zoom will also only work in adequate light. If there isn't enough light(typically outside daylight is required) it just digitally zooms the main camera.

Oh, i thought the three different cameras would make it better than it has proven to be.
I didnt realize it only did 2x for real zoom.

Actually ISO has nothing to do with exposure (in digital photography) and the sensitivity of the sensor can not be change. The sensitivity is baked in at time of manufacture.
Raising the ISO does not and can not change the sensitivity of the sensor. Raising the ISO does not introduce noise (grain), to any real extent.
ISO is applied gain that’s applied AFTER the exposure has already occurred. High ISO shots often show more apparent noise because you’ve taken an underexposed photo (lack of sensor saturation) and then applied gain (think of turning up the brightness of your screen) to the underexposed photo making the EXISTING noise (due to poor SNR caused by lack of sufficient light to bring sensor saturation) visible.
