That's very strange since it downloads normally on my phone. Can you tell me a bit more about the issue? I'd be happy to try to help.
actually i mean installing I'm sorry for the misunderstanding but its installing the problem
Usually, that would mean that the device doesn't have enough storage space to perform the install. The game takes up around 2GB right now, but it's very possible that you need to have a bit more than that freed up in order to actually install it.
Actually no i have free 7gb and it won't install
