Waterproof function is one of the essential functions of many flagship mobile phones. Among the waterproof and dustproof levels, IP68 is the highest protection level for mobile devices at present. The first number after IP represents the dustproof level, and the second number represents the waterproof level. For example, suppose this product has no dustproof function and the waterproof level reaches 7, then its protection level is IPX7. As the flagship of Android, Samsung has been equipped with IP68 waterproof function since S7. How to detect the waterproof function of Samsung mobile phone? The following small series will show you how to detect the airtightness of Samsung mobile phones.
Method 1: Go directly into the water.
Samsung's waterproof function can directly fill the whole machine with water. As long as you put it in the water, you can know that the air tightness of the mobile phone is completely fine. But if the air tightness is not good, the mobile phone will be cold.
Method 2: Pass the stress test of the mobile phone itself.
Since it is to test air tightness, in addition to using professional testing hardware, it is the key column of this tutorial, Samsung's own air tightness testing function. Let me show you the process.
1, open the dial-up interface of mobile phone, and you can open Samsung's own hardware test link as long as the official system inputs "*#0*#". Because the input of "*#0*#" will directly enter the hardware detection, Bian Xiao can only intercept the interface of *#0*.
2. When we enter the hardware detection, we can see many detection items, and our main goal is to detect the function of the sensor.
