ScrollRect swipe not smooth on Android

I'm trying to figure out why when I try a vertical scroll panel on Editor works great and when I try it on Android devices I encounter this behavior:

I have a long panel to scroll, so I swipe my fingers multiple times to go to the bottom. On Android devices everytime my finger touch the screen the scroll is interrupted and it restarts to scroll when i swipe. I havent' tested on iOS but in Editor works correctly, and I see a smooth transition.

It seems a problem with the dragthreshold, but I tried to lower it without results. Seems that the phone understand my swipe as "tap"...

This is the problem in a video: (my Unity App)

And this is the behavior that I wanted:

It's not a performance problem, the app runs at 60fps also when I scroll. My Hierarchy consists in:

Scroll View

Elastic - Elasticity 0.1, Inertia ON, Deceleration 0.2, Scroll Sensitivity 5
Components: RectTransform, Scroll Rect, Rect Mask 2D

-> ContentPanel Components: RectTransform (pivot 0.5,1), Content Size Fitter (Unconstrained, Min Size), Vertical Layout Group (Child force expand Height)

->-> Various Texts Components: RectTransform (pivot 0.5,1), Text, (Unconstrained, Preferred Size).

Nobody with an idea?
