Camera

I am using a Nokia3 and I have had bad experience with the app. When recording videos its as if I am moving my hand each and every second and that makes the video appear as if the camera was zooming in and out from time to time. I tried taking a video without having the device in my hands (because I thought maybe the problem was that the device is somehow "reading" my heartbeat) but I still experience the same problem. How do I get this fixed?

The camera doesn't takes good shots, there is blur in the image. Please improve low-lighting conditions it's very bad. If you can, please add stabilization in image and videos

Focus always trying to focus in video mode. You should have provided manual setting for video aswell like in camera you can change the focus to infinity auto etc. Too disappointed by this.
