I don't know what has Samsung actually done to their phones by messing up with the camera's software in one ui. Each and every single person is complaining. I have an s9 plus on one ui 2 android 10. The camera is showing hunting problems, it can't seem to focus on nearby objects and struggles quite hard, like focus in and out constantly on nearby objects. It can't seem to lock on. The autofocus is trash compared to my s7. The s7 dual pixel is like lightning fast.
