feat(device): allowing to get region from the device

[bsalesc]

This PR will allow applications get the region/country from the device, allowing them select the right experience depending on which country the device is from.

On android it will get from the language but on iOS there is a defined field for it. Web will throw an error saying that isn't supported.
