Virtual Joystick max axis value problem

I have problem with axis values of virtual joystick. You can see on this picture (-1) is value from virtual joystick (with input scale 1) in this position. If I will move joystick little bit up it will start changing, so it is something like “blind area”. I painted there a real value. Also, when I set input scale to 100, I got 133 max value. How can I get real exaxt axis values?

I had the same problem as you.
The solution is to change the dead zone value.
‘Project Settings’ → ‘Input’ → ‘Axis config’
dead zone setting Change the value to 0.
This will probably solve the problem.
Good luck.
