Connect DUALSHOCK4 and a smartphone with a USB cable or Bluetooth, and display the pressed amount of the button and the operation amount of the analog stick as a numerical value.

This app focuses on the amount of troubled analog stick operation.

The button pressed at the top is displayed, and the value of the analog stick is displayed below it in the following order.

X coordinate of L stick (-1.0 to 1.0)
Y coordinate of L stick (-1.0 to 1.0)
X coordinate of R stick (-1.0 to 1.0)
Y coordinate of R stick (-1.0 to 1.0)
Coordinates of R2 button (-1.0 to 1.0)
Coordinates of L2 button (-1.0 to 1.0)

Ideally, the L / R stick's overthrow is 1.0 / -1.0 with no stick touching.
In fact, it may not be + -1.0 even if you kill it completely. It is up to the game software whether the main character dashes with all my might. Also, the median is not actually zero. The problem does not seem to occur if it becomes + -0.0xxxxxxxx. If the software exceeds 0.1, it starts to move freely
It seems there is.

The R2 / L2 button is -1.0 when not pressed and 1.0 when fully pressed. The actual value also seems to be + -1.0. If it does not become + -1.0, the trouble that the accelerator does not fully open appears depending on the game.

The action to be taken in case of an error is described in the online manual.
