I have the Xperia Z and has absolutely nothing happened. Shower, swimming ... even cubes lol not understand how southern and boast a terminal that is waterproof, you should at least stand by time of warranty coverage, ie, two years, and if fuck you, that is a mistake from them, not from the guarantee. Obviously, I do not think that you've gotten in the shower with open lids, that sure is what Sony argues. One thing is that you drop, who often do not even notice and you're on the ground, and one that you go to get in the water and do not realize the caps, because it's in your hand and it shows. I find it shameful on Sony's part, really. Hope you got lucky because I have a mobile almost identical to yours and I would not that happen to me. Course. I would not give up. Even put a consumer complaint. Mostly because it is not normal.
