Free Screen Break Replacement covers breakage to the device screen and its accompanying surface glass leading to loss of screen functionality. If only the surface glass is cracked in any manner (e.g. minor, major, hairline cracks, etc.) either front, side or back, it will not be valid for a Glass Breakage claim. And if there is a mechanical breakdown due to the resulting damage (i.e. from drop, impact, pressure, etc.) then it will be classified as an accidental damage claim instead.
