Although it is clearly stated on the phone box that the cell phone is waterproof, most people do not dare to check if this characteristic is actually fulfilled. To clear the doubts, an application takes care to verify if the shield works.

The water resistance certification of a phone is an aspect that can be compromised by the passage of time and wear and tear. To check, Water Resistance Tester analyzes the device to know if the protection is intact or not.

There are many holes and crevices that must remain sealed so that no liquid enters the electrical part. From every port, the speakers and microphones, SIM trays, and memory slots, any gap can end up giving way.

The application, for Android phones, created by the independent developer Ray W, uses the barometer, a sensor available on various phone models, to detect if device isolation is still working.

Besides water, dust and mud are enemies of telephones.

Water Resistance Tester, as explained on the application page, can be used to determine if the device is still sealed through two of the most demanding dust and water resistance certifications, IP67 and IP68.

However, even if the phone has this factory certification, insulation can be affected by drops and the natural degradation of a device with age, which can compromise you if exposed to water.

This degradation can be noticed through mobiles with a barometer, a sensor to measure pressure. The app cannot be used or installed on devices that do not contain this internal component.

According to the opinions of the users, the platform works well although in some cases it may fail when the cover is not removed, something that is detailed when entering the software. It is key to press your fingers well and that the screen does not have the plastic cover that can alter the results.

Maximum protection

To know the resistance to water and dust of mobile phones or wearables, the IP certification is used, which allocates the first figure to detail how much it is able to withstand against dust and the second for the same with water.

The first digit goes from 0 to 6. The first index, that is, zero, implies that there is no protection at all before the dust and rises until it reaches 6, which implies that the dust does not enter the equipment in any way.

The second figure indicates the protection of the mobile against water. From the 7th, some degree of tightness is offered and already the 8th implies that it can be submerged at depths of up to one meter in fresh water for a maximum of 30 minutes.

These properties do not apply to ocean water since salt is one of the staunch enemies of electronic components due to its corrosive power and high conductivity.

While a cell phone with IP 69 certification, in addition to does not enter dust and that can remain submerged up to one meter en fresh water for 30 minutes, it is able to withstand exposure to short-range jets at high temperatures and pressure: 80 to 100 bar pressure at 80 degrees.
