I am having the same issue. The quality of the video is just terrible with a lot of noise in it. I can no longer adjust the resolution and stuck with 16:9 FHD 1920x1080 resolution. I am extremely disappointed as the camera was one of the reason i bought Note 10+ in the first place. Please do something.
Hi just an update. My problem was resolved yesterday. I turned om the camera, went to the setting, scrolled down and hit reset setting for camera. It went back to it's old setting and yay!
