Usually, when we use Nightscape mode and shoot the image, it says "Capture completed, Optimizing", so we think it has captured the image and we shake our phone to check the result of the image. But here's the thing, if we shake the phone after that message, it takes photos with more noise. So in order to get Better details, we have to keep our phone steady even after that "capture completed" message, untill that message goes off. If u keep ur phone steady till that message goes off, u will get significantly better Nightscape mode, which is on par with Nightsight on GCam which i am using. I have attached 2 photos of Nightscape mode. 1 is shaking the phone after capture message and another one is keeping the phone steady till the message goes off.
