Changing My Note 4 to Portuguese

[Wizard11]

I have a note 4 and would like to change the language to Portuguese. Not just the keyboard but the entire phones language. Does anybody no of an Application that does not need rooting to make this change. Thanks for any help.

If you go to Settings>Language & Input>System Language, you don't get Portuguese as an option? What's the exact model number of the phone? For unclear reasons, Samsung phones are known for restricting the available languages based on the region the phones were meant for.
