How to keeo camera roll from fast scrolling?

I have a samsung galaxy s9. I'm not quite sure exactly what activates it but you can fast scroll to the top or bottom of the camera roll in one swipe to avoid having to painstakingly scroll through hundreds or thousands of pics. I'm not sure if it does it after a couple times scrolling, or if you swipe your finger faster, and way, I can never seem to do it on purpose, but whenever I'm trying to scroll through a large section, it scrolls all the way to the top or bottom and I don't want it to. Does anyone know if that can be turned off? Or how it does it so I can avoid doing it when I don't want to? I try to scroll slower, take more time in between scrolls, etc. but it always seems to happen at some point anyway. Please help, thx :)
