I wouldn't like to say - You would be best returning this to the place of purchase or contacting Xperia care http://www.sonymobile.com/global-en/support/contact-us/ - May I ask how it happened

I have a drinking glass with a crack and it never leaked any water!

Don't risk it

I droppet it from about 1cm down to a table

I'm sorry but I'm not sure if anyone should believe that...

The only plausible way I can see that happening is if the back was already cracked, perhaps hairline cracks that you didn't noticed from previous pressure or drops and that drop just expanded the cracks even further, but its quite complicated

I just tested with mine by dropping it several times onto a hard GLASS table and it's perfectly fine.

The back on mine cracked during a recharge so it's very like to have happened. I've already sendt it in to get fixed😢

tovbro hope much did it cost?
