This app is a quick and easy way to check if your phone is waterproof. It uses the built-in pressure sensor to detect specific pressure fluctuations while the user touches the screen.

If your phone is not waterproof, you will see a graph of the pressure development within the phone. If you touch the screen, the pressure will rise and fall, and if it is sealed, the pressure will remain constant.

Note: This app has been developed and tested for Sony Xperia Z3, Xperia Z3 compact, Samsung Galaxy S5, and some other phones. It may also work with other water-resistant phones, like the Samsung Galaxy S5, but I need test feedback.

This app gives you a hint of all covers and plastic flaps are closed.
