Hello @Fernando ,
I'm using android+ to get the langage of the device.
The expected response, as described in the documentation is xx_XX for example fr_FR or en_US, which is a standard.
But the response i get on my testing device (Mate9) is fr .
This is really a big problem for me because my app uses translations and i need this value to call my webservices and get a response in the correct langage.
Can you confirme this is a bug ? and when it could be fixed ?
