An 8BitDo Switch controller adventure

> I tried calibrating the stick range to produce a more accurate analog sensing response, but could not do so. The controller has no calibration button combo, and Ultimate Software V2 can only install firmware updates on this model (which produced no improvement).

I personally had some issue with the joystick calibration on my 8bitdo Pro 2 and support gave me some instructions to do a hardware calibration which solved my issue. Not sure if it's the same for the Ultimate 2C BT?

    L1+R1+SELECT Hold 10sec start calibration
    
    Rotate both joysticks 3turns \*Simultaneously clockwise
    
    Fully press both triggers 3times
    
    Press all combination keys again to complete the calibration
    
    Turn-off the controller then turn on again
