iPhone storage says zero KB used
The built-in storage space display refuses to detect how much space is being used on my iPhone. It consistently says that 0 KB of space is being used, when the real number is obviously much higher. It won't recognize certain apps as having Documents & Data, even though some of them have several GB. Is there any way to reset this and get it to display an accurate number?
