I bought the phone a week ago, and now the vibrate is not working at all. It was at first, and I have tried everything I can think of, but maybe I am forgetting something or do not know a trick to get it working again. I smacked it on the lower back to see if that would help and after doing so and switching it back to vibrate it would give a soft vibration but only once. Does anyone know how to fix this without having to drive to a sprint store, and waisting my time? I have already tried calling them and the idiots had not a clue. Thanks for the help

Ive tried looking it up on the web, but I can't find a website with detail support on troubleshooting this kind of problem.
