Old info:

Fix Storage Menu:


After opening the Storage Menu for the first time, if it doesn't respond or gets stuck on the screen, you can make the Storage Menu work again by tapping Menu, then Manage, then Storage another time.  On the second time, the menu should function properly as well as go away properly when the back button is used or another menu is selected.
