I have an S9 and S9+.
When using the camera, the camera can sometimes fire off a rapid number of pictures 10-20 - whilst simply holding the phone in camera mode, which is annoying. It seems to co-incide with the way the camera is held, I beleive the edges of the screen sense ones fingers, but why that should fire the camera to shoot I do not know.
Wondering if anyone else is having this issue.
