Gamepads analogs have some kind of dead zone

[I needs Help]

Might be a ppsspp bug then, because my screen works fine with other things but won't register presses at times (/won't register at times unless I plant basically the entire from of my finger on the button), I do have the buttons pretty large and have been thinking it would be nicer if I could make it even larger but maybe what I need to do is make them smaller, it might be that a certain amount of points on the button has to be touched for ppsspp to register the press.
