Do you notice that something is wrong with your Huawei mobile? Maybe you have some other problem with the load, screen, microphones or the sensors that are in the terminal. If you have errors with any hardware component, it is best to take it to the official technical service. However, you can do a hardware test yourself with this little trick. Of course, follow the steps that we mark so you do not have any problems.
First, you must go to the phone app. From there you can access the hardware control to be able to do the different tests. Once inside the application, dial the following number * # * # 2845 # * # *. The Hardware Test option will automatically open.
Navigation through this interface is very simple. It is done through the volume and power buttons, and each one has its function.
- Power button: used in some cases, when the test requires it
- Volume + button: next test
- Volume button -: go back to the previous test
- Power button and volume +: go to the next test without completing the current one.
To exit the test, click on the home button on the navigation bar. The test will ask for confirmation, you just have to press again.
How to do the Hardware tests on my Huawei mobile
Enter this code in the dialer of your phone to start the test. To exit, just press the 'Home' button on the navigation bar.
Each test quickly explains what it is. When we started testing, we started by testing external components, such as the volume and power buttons. Then move on to the screen test. Here you check that the brightness works perfectly, as well as the tactile response. In this test, you must pass your finger over the points that appear on the screen.
Then he focuses on the camera. Specifically, in the focus of the different sensors: we just have to press on the screen and focus until the box appears green. Also test the front camera, autonomy and other components such as microphone, speaker, etc. charging connector. For this you need to have different accessories on hand, such as the USB C cable, headphones if necessary or even a wireless charger. If you don't want to do that test, you can skip to the next one without completing it by pressing the power and volume button -.
At the end of the test, a list will appear with all the tests that have not been completed. Good because we have passed them (in many you need components such as OTG cables, external microphones…). Or because there is some fault in the component.
This is very useful if you think that your Huawei mobile is failing in something. So you can check it before taking it for service. For example, if you see that the vibration does not work, you can jump to the test and see if it really works or is it because you have some option disabled in the settings.
