Is there a way to define the default language of a game instead of it using the devices language as a default?
You will need to provide more information here. The default language for what?
Is this a localization issue? What localization system are you using?
The localization package allows for setting a default language Localization Settings | Localization | 1.5.2
yeah. we put Galician language default but the application start in Spanish language
What does your list of selectors look like? The default should be at the top of the list.
