Because it is hypersensitive, the Slider Component is quite impractical for use in the reduced display of a smartphone. The slightest touching of the component area changes its value. I recommend amending the component so that only the tracking ball is sensitive to user touch.
There’s a new version of the slider component coming up at some point, which will be slightly less sensitive. However, it might be even better to expose that property so the user can choose the sensitivity of the thumb itself.
