z3 compact, phone cracked in my hand topic

People have been saying they left their phone, came back and it was cracked. Well I was using my phone, heard an odd "tick" noise, flipped my phone over, and it was cracked. One vertical crack, and a small horizontal crack running from the rim to the camera lens..

Currently on phone with Sony support, hopefully they won't be dicks.

Had phone just over 2 months, in that time it's been used extensively, no issues yet.
