Sony engineers have invented some cool new technology, allowing its Xperia phones to know when they are underwater. Before you shout witchcraft, Sony actually uses a detector that generates a test tone beyond human hearing, recording the sound through two microphones on the handset for processing. This generates spectrograms with different values allowing the phone to know whether it is in air or water.
So what has Sony done with this tech? Created a special suite of Underwater Apps of course. These are apps designed to show what the phones can do underwater. There are six apps to choose from and all are just bit of fun from the sounds of it. We say that, as Sony has only made them available for the T-Mobile Xperia Z1s and Xperia Z i.e. you can only download them in the United States (for now).
We have included all of the Play Store links below and some pictures/videos showing what each app does. It can’t be too long before the APK’s are leaked – until then enjoy the videos below. If there are any developers looking to use this in their apps, then visit the Sony Xperia Developer GitHub to get the code.
Update: The APK’s can be downloaded here, however the apps check the build prop so if you are using a different phone it will still not work.
Save a fishy friend by dunking him in water
Process your photos the old-school way
Grow a mutant creature by watering it every day
Sing in the rain without forgetting the lyrics
Pilot your very own submarine in your sink
Stay dry in the rain or do your best to try
