In this article, you'll learn how to change the Control Stick orientation on the Joy-Con controller.
While this option can be enabled at any time, it is meant to be used with software played with the Joy-Con controller in solo horizontal grip.
This option will not work optimally if the Joy-Con is either attached to the system or used in solo remote grip or in dual controller grip.
With this option enabled, only the control stick orientation changes. The button inputs will remain the same as when the controller is in solo horizontal grip.
Complete these steps
For optimal use, ensure the Joy-Con is detached from the console and set in solo horizontal grip.
From the HOME Menu, select Controllers, then Change Grip/Order.
Hold the Joy-Con horizontally and press the SL Button + SR Button.

Be sure to perform this last step, otherwise the new setting will not be applied to the Joy-con.
Remember that once this setting is enabled, the control stick orientation is changed. However, the button inputs remain the same.
