Screen

Your iPad limited warranty does not, in general, cover any screen damage - except in those situations where a manufacturing defect can be proven.

You might be best advised to seek assistance from the Genius Bar at your local Apple Store - where your iPad can be assessed by the technicians.

If you did NOT purchase, paid extended, two-year AppleCare+, then you have NO warranty coverage for a cracked sceen that was caused by accidental/incidental causes.

The standard, free, one-year AppleCare ( NO + ) only covers manufacturing issues/defects.

Unless you can prove the cracked screen was caused by a manufacturing defect/issue, and you did NOT purchase, the extended, two-year AppleCare+ warranty protection plan, be prepared for an expensive repair/replacement device.

The U.S. repair/replacement costs, WITHOUT tax, are listed here.
