3 days ago while in Krabi, I took the XZ for a snorkling/swim. Within 10sec at less than 1m into the water (seawater to be exact) the phone died. I went up the boat, the flaps were still secured. I opened them and greenish water started dripping out. Ouch!
Came back to SG today and went to Sony centre. The lady said they will do a water test. Basically to test if it is still water sealed. If yes, means I didn't secure properly, the warranty voided. If no, means I still got a chance to get it serviced.
I took my Xperia GO for kayaking last year with the phone fully submerged in sea water at times, still rocking well today. I put the same faith in my XZ and failed me.
Good thing is, my SD card and SIM card are well, and my data (especially photos) are still alive. Phew!
Anyway I'll get the 'lab' result next week. Fingers crossed.
