Xamarin Forms localization strings not showing up on Galaxy s3

I'll make this quick.

I have a Xamarin Forms app, and I am testing the localization feature on a Galaxy S3 device. In the Emulator, the strings change without issues, both in XAML and code behind, when changing the language.

On the Galaxy S3 however, the strings remain in the default language state ( english, although the device in set in another language ).

Any ideas on this behavior ?

Thank you!
