Any phone with OIS or AF will rattle if you shake it hard enough. It's just the springs of the lens assembly hitting the endstops of travel. Shouldn't damage anything unless you really hit it quite hard (or, repeatedly, as a motorcycle would). I've also noticed you can sometimes get rattling from buttons on a phone too. Could also be that.
