Resetting a PS5 controller is the process of restoring it to its default settings. This can be necessary if the controller is experiencing problems, such as not connecting to the console, not responding to input, or if you simply want to start over with a clean slate.
There are two ways to reset a PS5 controller: using the reset button on the back of the controller, or using the Settings menu on the console. The first method is the simplest, but it will only reset the controller’s connection to the console. The second method is more thorough, and it will reset all of the controller’s settings, including its button mapping and sensitivity.
