The photo is not looking good due to a reason. The setting for the moon works when it is over 30x zoom mode. Before that the phone is not able to preprocess the image with the right amount of light due to which the moon shot is not clean.
Try to increase your zoom magnification to the full 100x and let the Samsungs camera software do wonders. You need to hold phone stable for 1 second before clicking and you will see the noise disappearing and get clean looking Moon shots.
