2 years ago The application now using the device preferred first language as translation target. It's should works well.
And we do not have the available target languages list from vendors and different vendor supports languages and lang-code are various.

Maybe specifying a default target translation language is a good feature, which requires getting parameters for various languages in a web service and displaying them on the front end .
