A new app for Android is claimed to be capable of testing the integrity of your smartphone’s waterproof sealing even without using any water. The app uses only your phone’s barometric pressure sensor.
Most flagship smartphones such as Samsung’s Galaxy S21 series have a native capability to resist water submersion up to 1.5 meters deep, thanks to their IP68 rating. This gives you the confidence that your device is deemed fit enough to withstand water, dust, and sand. However, it can be hard to prove that without actually submerging your device in water.
