Android newbie here. My son has a new Galaxy Tab 4...8GB storage....plus a 32GB SD card installed. He managed to fill up the device storage quickly. So I just used application manager to move a bunch of apps to the SD card. Was easily 3GB of apps (there were a few huge ones in there). However, in settings, the available device storage only changed from about 600 MB to 800 MB. The apps are most definitely on the card. So am I missing something or doing something wrong?
