It looks like Sony has had a radical
change of heart when it comes to using the Xperia Z smartphones under water.
According to manufacturer, those who use the Sony Xperia Z5 under water to take
a photo will void the warranty. This is also valid for the other two
smartphones in the Xperia Z5 series, the Z5 Premium and the Z5 Compact.
Ever since Sony launched the Xperia Z lineup of Android-based smartphones and
tablets, the company has often advertised these devices as dust and waterproof.
In fact, the company's promotional material often suggested that the Sony
Xperia Z smartphones can be used under water, and some of the material showed
the devices taking pictures under water. Here are a few examples:
More recently, however, it looks
like the manufacturer has changed its stance on using its waterproof
smartphones and tablets while completely submerged.
Here's what Sony has to say about
the Xperia Z5's IP68-certified resistance against water and dust. This is a
quote from the official product page:
You should not put the device
completely underwater or expose it to seawater, salt water, chlorinated water
or liquids such as drinks. Abuse and improper use of device will invalidate
Right after, Sony links to a dedicated page on its website that details
the company's stance on water and dust protection. Sony states that the user
"should not use the device underwater, such as taking pictures".
Exposure to drops of rain, spilling drinks on the device, and using the phone
with wet fingers are all acceptable, but the company repeatedly advises not to
use the devices underwater.
Sony notes that the IP ratings of these smartphones guarantee that the phones
remain functional after being submerged underwater in strictly controlled
experiments, where the phone is carefully inserted in a tank, and then
carefully removed after a certain amount of time. Pressure levels are likely to
skyrocket if you use the handset while swimming, and the phones are not
guaranteed to last in these harsher conditions.
