How to decrease touch sensitivity (Android)

i followed a tutorial on youtube on how to change camera angle by swiping on screen(android). the results came out to be awesome but touch sensitivity is too much . Can anyone help me in reducing touch sensitivity.

Multiply by Delta Seconds first - just before Adding Input. Otherwise you will get inconsistent results depending on the framerate. And then reduce / increase the swipe speed.

What to multiply by delta seconds ? Swipe speed ?
