Screen cracked on opening case

I received brand new FP2 yesterday, after two months wait.

The screen cracked (deeply, breaking the display) when I opened the case for the first time.

I have immediately asked for a replacement, but is this a known problem? If so it seems like a major design flaw.

Also, does anyone know how to wipe my personal data from the phone before returning it, now that the screen does not work?
