I had a cracked screen.

Actually the glasswork broke all around the edges so that the screen just came away.

First thing I know about it was when the screen was flapping about on my wrist whilst I was typing an email - still working.

The watch suddenly did this without any impact at all.

I complained to Apple about this and after some back and forth they agreed not to charge for the replacement.

I think there may be an issue with the glass cover because I have seen others with a similar problem.

If you have cracked your screen I think the best thing to do would be to contact Apple or make a genius appointment so you can talk to someone about it and make your case.
