If you head over to Sony Mobile’s support page on water and dust protection, you will find several statements on Sony’s new policy including: “Remember not to use the device underwater” and “The IP rating of your device was achieved in laboratory conditions in standby mode, so you should not use the device underwater, such as taking pictures.”

I've got a Sony "waterproof" mobile, an Sony Xperia Z Ultra. TBH I would never use it underwater & it wasn't a consideration in my choice of handset. It doesn't surprise me in the slightest that a mobile phone isn't capable of meeting the stated specifications.

I've got a Z3 Compact, and since I cracked the glass back the first week I got it (and have yet to get it fixed nearly a year later), coral reef diving with it has been off the agenda anyway...

I also see 'waterproof' as hopefully saving a phone if accidentally dropped in water. Wouldn't dream of using my S5 in water.
