Afterglow XBox controller spins cameras.

I have this Afterglow XBox controller that works nicely with all my devices... except for my Samsung Galaxy S8. When I use it to play Minecraft, all the movement controls work. But when I try to use LT and RT, they suddenly get treated as "joysticks" and start to spin the camera. LT is "left stick X axis" and RT is "left stick Y axis" .
