Must use Playerprefs.save ()?

It is the first time I am working with PlayerPrefs.

I did a test, and used PlayerPrefs.SetInt ("Test", 1);

And I saw that he already saved without me having to call the PlayerPref.Save() function

Other words at what time I should use the Save function?

 

Usually you will need to call Save(). However PlayerPrefs are also saved when the application quits, so there might be a chance that you set the value before and now see the previous result.

 

I'd use it in a custom SaveGame() function that's called when the player chooses to quit the application. Although PlayerPrefs do seem to save automatically, it's best to be safe than sorry!
