Two steps back one step forward, tinny sound should be non-existent in large flagships since years ago, there's absolutely no excuse for that. As for "camera shake", I don't know if that means better OIS to begin with or more resistance to the common defect of focus hunting and OIS "wobbling" after a few falls even without any visible exterior damage. The latter would certainly be welcome.
