"Keyboard does not show when trying to add a new contact."に関する回答You might also have this issue i just experienced. Double click your home button and if there is a blue-million windows opened, then close them all. For some reason it seems that there is a “Limit” as to how many windows can use the keyboard at one time. Not sure what that limit is, but if there are too many windows opened, you might lose some functionality. Good Luck!
