Hi Everyone
Same thing happened to me, On Christmas day while swimming with my nephew, I decided to take a few pics of the little guy while under water, I did after all have a waterproof Sony Xperia Z2....I will admit, I did have massive trepidation, and made extra sure all ports were closed PROPERLY, I then took in under the water for less than a minute, then the screen died, and subsequently the phone was completely dead.
I got in contact with Sony mobile ZA on their Facebook page, to inform them of this, they instructed me to take it to MTN, Which I did, today i found out that the device came back from Sony, as "unrepairable" and i immediately phoned the Sony call centre to find out when i can expect my replacement phone, Turns out, on the job card it says that "severe water damage due to ports not closed"...So basically the middle finger from Sony...I have again gone back to their facebook account and they requested the IMEI number to assist me...Lets see what happens
