The touch screen in general is too sensitive. I have more issues with what you're describing in Ninja Gaiden in FIFA. I could be running down field with the ball past all the defenders and the touch screen will register a kick when i didnt even touch it and all of a sudden my character kicks the ball out of bounds -_-...
In FIFA though, you can disable touch controls.
Ninja Gaiden pretty much enforces them. I have smaller fingers, so the touch screen was not an issue for me in the game.
