Sony is warning users of its Xperia phones to not use their phones underwater, something that might come as a surprise considering the fact that Sony has used waterproof rating as a big selling point for its phones.

The devices have a rating of IP68 for water resistance, which is the highest a device can have. Despite this, Sony is now saying that its devices should not be used underwater.

"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," said Sony in a statement. "Do not use the device to take photos while performing any type of activity underwater, including diving or snorkeling."

The warning was issued for the company's Xperia Z3+, however, it also covers the new flagship, the Xperia Z5. Because of the fact that to achieve the rating, the company was required to operate the phone underwater, Sony is basically discouraging users from taking their phone on a dive or for a swim.

So, when can you use it? Well, Sony says users can use their device in "wet conditions." Users could probably take their device for a brief swim but should realize that it's completely on them if something happens.

Of course, that doesn't render the IP68 rating useless. In case of an accident in which a user drops their device into a body of water, the device is much more likely to be fine than without the rating.

The recent warnings are in contrast to what Sony has marketed in the past. It has arguably even encouraged using its devices for underwater photography and even launched apps that need to be used underwater.
