Mobile Input Not Accurate

I am developing a game similar to Subway Serfers and what I want to do is implement a swipe functionality. However, if I use the Unity's documentation for mobile input in Update() method, some touches are omitted, thus some swipes, either left or right, does not result in a turn. If I swipe more slowly, though, everything is all right.

My question is - is there a way to handle all swipes and touches on the screen instead of relying on the user's touch/swipe will be right when Update() method is called? Imagine the player plays the game with 30 fps, this will mean that Update() will be called every 0.03 seconds, which is so much for an intense game.
