I know this has plagued older iPhones but I can't find many reports on the 7 so asking if anyone else is in the same boat? My 4.5 month old 7 has developed a loose rattling mute switch. When in the ringer position it's tight as a drum and the only rattle is the faint one from the camera. Once in the silent position it's really quite loose and rattles if you gently tap the switch or shake the phone. Just interested to see if other people have a similar thing and the likelihood of the switch failing as to wether or not it's worth pursuing with Apple.
