Probably I messed the submit by selecting phone/tablet, but this is not a "Firefox for Android" bug, it's a Desktop bug and it'ts happening in my Windows 10 tablet.

The apz.touch_acceleration_factor_* prefs don't get used for touch inputs, so I wouldn't expect those to have any impact when using a touchscreen. The apz.fling_accel_* prefs should have an effect, but only when doing multiple flings in quick succession.
