I currently have Android 4.2.2 on a Samsung Tab 2 7.0" tablet. Up until recently the "Move to SD card" option wasn't showing in Application Manager. But very recently, Samsung shipped a new update that didn't change the version number, and they said it was to correct a few minor problems. Then I happened to notice that the Move to SD Card option was now showing in Application Manager, so I decided to try it first on some games. The button briefly changed to "Moving" and when the move was complete (allegedly) the button was change to Move to Device Storage. However, even though the storage allocation numbers reflected a change, when I viewed the actual folders, first with an Android file manager, and then with the tablet connected to my desktop, I found that nothing had actually been moved to the external SD card.
