The volume button and the display button are invalid.,I don t know if it s because I m pressing hard

If your phone's keys are out of order, we recommend you:

1.If you cannot use the back button to go back to the previous interface or exit when running a program, it is recommended to click the home button to return to the standby interface and try to re-enter the program.

2.Turn off your phone and restart it.

3.If the back button, menu button, recent application button, and home button of your phone are not available, it is recommended to uninstall and delete the recently installed software.

If the problem persists, it may be a problem with the internal hardware, it is recommended that you bring the three-pack certificate of the mobile phone and send the mobile phone to the nearest Samsung service center for the engineer to check the machine.

If the volume of your phone automatically decreases, please follow the following methods to troubleshoot:

If you set the scene of automatic volume adjustment in the Smart Life app, the volume will be automatically adjusted under the trigger condition. If >you no longer need the scene, you can close the scene or press and hold the scene card and click "Delete" to delete the scene.

2.Check whether the scene is set in the smart assistant.

If you no longer need the scene, you can turn off the scene or press and hold the scene card and click "Delete" to delete the scene.

3.Whether you have used headphones or protective cases or leather cases.

If you are using a case or holster, you may accidentally touch the volume button and squeeze the volume button, so please remove the case and try to use it.

4.Whether the scene is hot.

Huawei's unique temperature protection mechanism protects the phone's hardware when the phone's temperature is high. For example, when the temperature is too high, you are using your mobile phone to play audio, the mobile phone will activate the speaker protection, **The sound will become smaller, and it will automatically recover after the mobile phone cools down. This is normal, please feel free to use it.

5.The volume bar is displayed without any operation and the volume is adjusted automatically.

If the volume bar is displayed and the volume is automatically adjusted without any operation, it may be a hardware problem (the volume button or headphone jack is abnormal), so we recommend that you back up your data in advance (third-party apps such as QQ and WeChat need to be backed up separately) and bring your purchase voucher to the Huawei Customer Service Center for testing.

What to do if the volume button fails The solution to the failure of the volume button on the mobile phone is as follows: 1. Forced to use the soft adjustment method in the system's "Set Sound Volume". The touch screen drags the volume control point and moves it to the desired position, but this method is more troublesome to use.

For example, if you want to temporarily reduce or increase the volume when you want to adjust it once, it will take time to operate to achieve the goal, which is far less convenient than pressing the button. 2. Because the miniature button element that controls the volume is too small, even if you open the shell and find it, the individual will repair it unconditionally, and it is recommended to send it for repair. 3. This situation is rare for new mobile phones.

This kind of starvation mostly occurs on mobile phones that have been used for a long time. Most of them are caused by serious oxidation (dampness) of the inner contacts of the micro buttons, or the deformation of shrapnel (fall).
