Screen has suddenly appeared like this. it is still under warranty No knowledge of drops or impacts. Can anyone confirm that this is a physical damage to the screen and the fix is a screen replacement that wouldn’t be covered by warranty?
That is a crack in the screen. It will have to be replaced.
There's no warranty cover for that.
The relevant part of the manufacturer's warranty states in part: "The Limited Warranty described herein does not cover: (a) damage or malfunctions caused by accident, misuse, neglect, abuse, acts of God or other external causes; .....".
You can check what the warranty for the tablet shows for your location as not all warranties are the same.
