Love it but one frustrating thing

I have loved this game for ages but now there is one BIG problem that is frustrating to me. When ever Im running and I jump or turn it wont let me than I die. But I have a 4s and I dont know if it is because of that but please fix it. Ill keep playing it because it is fun and challenging.
