That’s the sounds some iPhone 5 owners get when they shake their device,
according to posts on the Apple.com forums/a. Some claim being told by Apple
that it’s normal noise created by camera competents, other say it’s an unglued
battery (the latter problem can be fixed with a trip to an Apple Store). In
either case, it’s annoying, as numerous YouTube videos show.
