Xperia XZ has an IP rating that protects it from accidental water spills, but it's not advised to take pictures under water with it, or totally immerse it under water.
There are other ways to take advantage of your Sony device’s water and dust protection. You can use the device in the following scenarios:
- When your fingers are wet.
- In dusty environments, such as a windy beach or when hiking along a dusty trail. Just make sure you wash off all the dust on your device using water from the tap afterwards.
- Taking photos and movies in wet surroundings. Remember not to use the device underwater. If you accidentally get the device wet with non-fresh water, wash the device with tap water.
