I cannot change the language in my Nokia Lumia 1520, it has changed into French on its own from English and I can't even open the language page in settings.
It started by changing the language on its own to French every now and then but I was always able to change it back by opening the language page in settings. But for a week now I've been unable to open the language page, the option is grey out.
I've been looking for similar cases on the Internet to find a solution but I haven´t found this problem anywhere.
Any help would be much appreciated.
