I have used Sony Xperia Z for 2 years and I didnt find this phone interesting. The waterproof feature was not a successful feature in this phone because of this feature the company had to seal the phone completely due to which there remained no outlet for the heat to expel from the phone. Due to all this the phone use to be so hot all the time and sometime if you plan to play a game on your phone, the phone use to turn into burning coal and due to excessive heat sometimes the phone use to hang and freezes for hours. Once I had to get the phones screen changed, so the executive told me that the waterproof feature will no longer be used because the phone cant be sealed again once it is opened which is again a waste feature. Otherwise even the phone had a lot of limitations. The camera quality was 13.3 megapixel as per the companys claim but the quality was like a 5 mp camera. Overall I didnt like the phone at all and though this model is discontinued but still by the chance you get to buy this phone as a resale or anything, dont buy this phone.
