When you think of a list of objects which could survive on the seafloor, it includes mostly reinforced metal structures or the strongest of submersibles, not complex electronics, and especially not a smartphone. Now however, Sony has proved that its Xperia Z2 smartphone is the Captain Nemo of the smartphone world, through a completely accidental occurrence.

A Swedish man named Alexander Maxen was on a fishing trip near Gothenburg, when his Sony Xperia Z2 phone slipped overboard and rapidly sunk to the sea floor. Not long afterwards they were surprised to discover that they could stillcall the phone, which amazingly still had reception.

When it was brought back to land, shockingly, the device was able to charge and then be operated as normal.

Six weeks pass by, and Alexander return with SCUBA diving equipment in order to find his phone. Eventually, the Z2 was found at a depth greater than 10m, with only minor damage to its glass casing and a dead battery. When it was brought back to land, shockingly, the device was able to charge and then be operated as normal - even so far as continuing to make calls.

We all knew that the Xperia Z2 was waterproof - its manufacturers state that it “can be kept under 1.5 m of fresh water for up to 30 minutes in compliance with IP58” - but we never knew that it could survive this much aquatic punishment. Not only is the salt water it was immersed in highly corrosive to the sensitive electronics inside the device, but also at 10m+ in depth, the pressure would have been enough to crush less hardy devices.

The one question that remains however, is that if a manufacturer can make a device that can survive the ocean depths, why can't they make one that has a screen which won’t break?
