Game's Language

Is there a way to change the game's language?
I have a phone that I bought in France, and I installed the game back there and then.
I'm living in Australia and switched my phone to English, but for some reason, the game is stuck in French.
While I don't mind it too much, plants and zombies have different names in French and English, and when someone refers to a plant/zombie in this forum, I have to go on pvzheroesdeck to find which plant they are talking about, which is a little annoying.

Did anyone manage to change it?
