At present, many mid-to-high-end Android phones have IP67 or IP68 water resistance, but this function is not permanently effective. As the use time is longer, the waterproof performance may become weaker. We generally don’t perform waterproof tests on our mobile phones. It turns out that as long as you use a mobile phone app, you can also understand the degree of water resistance without getting the phone wet.
Programmer Ray Wang wrote the Android program Water Resistance Tester. His original intention was to help users who have sent their phones for repair or used them for a period of time to understand the water resistance of their phones. As long as you download and install it in the Google Play Store, open the program and press the screen firmly as instructed, the program will check and display whether the phone is qualified. (The program is for reference only, the programmer stated that it cannot be 100% guaranteed to be accurate)
The Water Resistance Tester explains the principle behind it. It uses most of the built-in air pressure sensors in mobile phones to detect whether the waterproof seal is still stable. Some netizens tried to challenge the accuracy of the Water Resistance Tester. After passing the test, the Galaxy Note 20 Ultra, which has an IP68 rating, removed the SIM card slot and retested, but the result was unqualified. As for the TCL 20 Pro 5G, which does not have an IP rating, it was unqualified in the first test. The program itself is free to download, but if you appreciate the developer’s creativity and thoughts, you may wish to purchase the option to remove ads for 1 USD as an encouragement.
