I have the same problem. I sign out of facebook and that seems to help a little but the game still crashes quite often. Sometimes I think that it’s just my crappy phone but then I think back to before I made a facebook account and signed in, crashes rarely happened. So the only advice I can give you is to not sign in in the first place. If you already have, log out and try to take on the caves with the 3 pigs that it gives you to use rather than your friends powerful birds. I know, it sucks.
