The iPhone's "battery door" incident should also make many Android users silently think: Is my battery healthy? My mobile phone is not OK, etc. For Samsung users, it is relatively easy to detect whether the battery is healthy or not. Official The "Samsung Members" app was launched in December, which includes more than 10 hardware tests such as battery, Wi-Fi, sensor, touch screen, connection port, etc. If you encounter problems, you can do it yourself. Do an initial test.

Go to Google Play and search for "Samsung Members" to find it. It can be installed on every Samsung mobile phone, regardless of model.

Supplement: The description mentions that the program supports devices above Android 6. If you encounter Google Play saying that you do not support it, you can try Samsung's Galaxy Apps to see if there is any

After installation it will ask you to log in to the Samsung account BF421ZL1 . The reason why you need to log in is that if necessary, the test records that run out can be uploaded to the Samsung cloud, which will contain some records or condition descriptions that the maintenance personnel can understand, so that the maintenance center can quickly transfer the data to find out the problem. , much clearer than speaking to customer service.

In fact, this App not only has the function of hardware diagnosis, but also combines customer service, discount information, tips teaching, etc. It is a bit like integrating the functions of my Samsung and Smart Tutor.

There is a "Diagnosis" tab on the far left. After entering, click "Test Hardware" in the lower right corner, and you can see many test items. The items should be different with the mobile phone. For example, this screen is from Note 8, and there is S Pen. detection.

If you want to test something, just click it directly. For example, battery, it will tell you the battery life very quickly: good, not expressed as a percentage. I don't have any old Samsung mobile phones at hand. , and tell us what the situation is.

Wi-Fi, Bluetooth, sensors, cameras, speakers, etc. can all be detected. When you find that there is a problem with your phone, you may be able to do a preliminary check first.

If a problem is found after an inspection, you can click Remote Support, or find a service location.

Click on the service location, and it will guide you to search for a repair center. If you choose remote support, you will enter the Smart Tutor program. You will be asked to provide permission first, so that professionals can remotely control your mobile phone, and then call customer service. The request for the connection code continues. The remote diagnosis of the maintenance personnel is also clearer than oral, and the problem can be caught faster.

At this point, some people may think: Isn't this the same as the engineering model?

As far as the test items are concerned, it is still not the same. For example, in the test of Samsung Members, there is no red, blue and green three primary color inspection of the screen (some have this mode to check whether the screen has bright spots), and the test items of S Pen and sensor. Not the same.

In the engineering mode, you can see more pressure-sensitive responses of the S Pen, and actually test the proximity sensor, so the app can actually be used with the engineering mode.

But it doesn't seem to be detected here what happens if the phone freezes....

Because I have all passed the test, I don't know if this can really catch the problem, or what the response will be after the problem is caught. This method should be compared to people whose mobile phones are old or have minor problems. I feel it, if your old machine has detected something, you can share it with us.

Different mobile phones have different codes for calling out the engineering test mode. For example, on SONY Xperia mobile phones, you can input *#*#7378423#*#* on the dial key. There is a Battery Health test in the Service Test, which can test the battery health. Please share with your friends who use SONY mobile phones~
