I have the problem too where no matter that the phone is set to English language, if i respond to any text it uses french auto-spell. Often I have to manually set the language in the text message menu's to English in every instance of creating a text message. Then other times it is totally fine. It seems as if it somehow resets itself back to FR depending on the text it receives.
I have no solution.
I have had the same problem as someone else who has posted a comment. my phone keeps defaulting back to French when I am texting. Plus I cannot find any way to add words to the predictive texting dictionary. Very frustrating!
no matter how I set the language to ENGLISH it still goes back to French when I want to send a text message.
I have contacted their hotline but they just tell me how to set the language and ignore my query on the fault
