If your not panning with the moving object or it's not possible try pro mode highest iso and min 1/125 shutter, spot metering and so its always ready and toggle on to resume last settingIt is the typical Samsung phone. It is very fast and speedy. One UI is awesome! getting closer and closer to stock Android. The camera zoom is very very nice. See my zoom photos in the photos thread!
My 2 concerns are the slow shutter for moving objects and the overall size of this beast!
I might trade down and get the S20+
I assume the sports mode is still missing since S9's and 10's/20's are more like aperture priority on auto
