The tightness of a smartphone can be tested without liquid exposure. Even disassembling the device into parts is not required.
The Water Resistance Tester application showed a good result after testing on smartphones with the Android operating system. This is a kind of electronic water resistance tester based on the operation of a barometer. And since this indicator may deteriorate over time, then the test results of devices will be different.
The application uses a rating system based on barometric data. To test the smartphone, the tester is installed on the device, activated and evaluated. The user only needs to tap the screen with his finger.
Even though the app is released in English, it is intuitive. All functions, both basic and additional, are easy to use. The smartphone receives an overall rating - tested or failed.
According to user reviews, the app works great. Pressing the screen with your finger is enough to find out the real level of water resistance. But, if you open the slot for a SIM card or memory card, then the previously displayed data will no longer be relevant.
Similar applications can be installed on devices offered for sale on the OXO website. In the section
"Phones, smartphones" there are more than a thousand active lots, including models from different manufacturers and years of release.
