Why can't the mobile phone be opened?

If you use a Huawei mobile phone, please observe the fault of the mobile phone and troubleshoot it according to the following corresponding methods.

1. When the phone is turned on, the screen is black, but it rings or vibrates.

It may be a screen problem. Please bring the relevant purchase voucher to the nearby Huawei Customer Service Center for more help.

2. When the phone is turned on, the screen is black, there is no response, or the red light flashes, or it is turned off immediately after the phone is turned on.

(1) The battery may be exhausted, so it is recommended that you use a standard charger to continuously charge for more than 30 minutes, and then try to turn it on.

(2) It is recommended that you press and hold the power button 15 seconds or more and try to restart the phone forcibly.

(3) If the above methods can't be solved, please bring the relevant purchase voucher to the nearby Huawei customer service center for maintenance.

3. Boot into HarmonyOS system interface, EMUI interface and quick boot interface.

(1) You may have accidentally pressed the combination of the power button and the volume button to enter the special mode. It is recommended that you press and hold the power button 15 seconds or more, and try to forcibly restart the mobile phone and enter the mobile phone desktop normally.

Warm reminder: Mate40 series and MateX2 phones are forced to restart their phones by holding down the volume down button and the power button for more than 10 second.

(2) In order to avoid this situation in the future, I suggest you check whether the key is easy to get stuck or the protective sleeve you are wearing squeezes the key.

(3) If the above methods cannot be solved, please bring the relevant purchase voucher to the nearby Huawei customer service center for more help.

Warm reminder: If you have not backed up your data before, you may lose your data during maintenance.
