Hi, I'm from Spain, my loopy is chinese. I don't know how to change the language. Please help me!
as far as I kniow, the language is selection is done in iOS.
in iOS 8.3
System > General > Language&Region
there should be the iDevice Language listed and below that the "preferred Lanuguage Order" and a list of Languages (may only be one depending on what you have installed on your evice). Apps will use the first Language in the list (top to bottom) that they support.
What Languge is your iDevice displaying for the iOS menues? I dont know if jailbreaking affects this.
