Perhaps this positive feature depends a damage together, I was "allowed" to experience last week:
The Z3 I took a walk with light frost with (the mobile phone tucked in your pocket). I am 100% sure that it has thereby been no external forces (no shock, no sticking). Back at home, was the complete display fragmented (s. Photo).
As a layman, I suspect that there was here an environmental stress cracking. The case is indeed made of metal, which has a different coefficient of thermal expansion.
Unfortunately, Sony denied a free repair on the grounds that there had certainly given external influences. The repair cost me now 204th And on top of that Sony refused to publish the broken screen, I would have gladly given an expert for review.
As a customer, you are such a group over completely powerless.
Finally, I want to "praise" the customer support from Sony. It took almost an hour uninterrupted trying to be made Hotline. After every 7.5 minutes you will be thrown out of the line, because Sony "would expect" the customer no longer wait.
