For example when there is an incoming call you will not see the screen as it was before. There are only two options either to Answer or Unlock, these animations are good to see. Are you wondering if you tap the Answer button to pick the call and it is not working? This time you should not tap the Answer button instead sweep along the direction shown in the animation to pick the call.
