I am experiencing the same issue and it is extremely frustrating. Very upset to have shots that I have taken turn out like this, I would not have taken a zoomed photo if I knew the outcome would be this bad! Did not have this problem on my last Galaxy phone!!! *non-zoomed pics are very nice, thankfully
If there is a fix please let us know!!!
Terrible customer service from samsung. I use the camera on my s9 to take photos of roofs for customers to show them work that needs to be carried out but the pictures are just terrible when you zoom in. Again, like others, never had a problem with my old s7
