one of them is the Dead Zone

It is like it has no dead zone

and there are some dead zones on the 2 L and R buttons but just push the buttons on the edge and you should be

Joysticks have a large dead zone which made playing shooter games nearly impossible

The analog sticks have a slightly noticeable dead zone and are on the smaller side, but they are passable

I have used controllers that seem to have a dead zone in the center (so it felt like using a d-pad), but this controller feels better.

If you're looking for some to test it, I recommend checking out Shadowgun Dead Zone, or Dead Trigger 2, both FPS games on android

The dead zone was shifted to the left significantly so it picked up subtle pushes to the right, but I had to nearly push the left joystick left half way before it picked up

it has a couple of dead zones on the right

It is like it has no dead zone

Talking about dead zone

Xinput works fine, no lag, and no dead zones (verified with several different programs)

When I had try it on kill zone 3, you really feel something when firing kinda like a small earthquake on your palm

The controller has a large dead zone and I verified that it wasn't an android software issue as it behaves the same way under Windows 7
