I am playing on the new experimental patch 1.17.154657
The new sensitivity options do not seem to lower/higher the speed of camera movement regardless of where they are on the slider, also when the sensitivity slider is all the way to the left it makes aiming feel really “janky”.
Step 1.
Open options and navigate to controls
Step 2.
Move camera vertical slider all the way to the left
Step 3.
Move camera horizontal slider all the way to the left
Step 4.
Now test the aim by turning the analogue stick round in circles
Works on all the other sliders too
Seems like the sliders only do something to the diagonal aim
