What should Huawei do if it has been stuck in the boot interface after enjoying the 8p crash?

If there is a blue screen, a black screen, a white screen, a crash or a jam during the use of the mobile phone, it is recommended to press and hold the power button 10 second or more to forcibly restart the mobile phone, and troubleshoot it according to the following methods:

1. Use the mobile phone while charging, and confirm whether there is any abnormality.

This situation will lead to overheating of the mobile phone, resulting in abnormality. It is recommended to avoid playing with mobile phones when charging.

2. Confirm whether there are multiple applications with exceptions at the same time.

Running multiple applications in the background will take up too much memory or other resources, and the overload of the mobile phone may be abnormal. It is recommended to avoid running multiple applications at the same time.

3. Confirm whether there is any abnormality when playing large-scale games or running some specific apps.

Some third-party applications are incompatible with the system, which may cause the phone to crash and the system to get stuck, leading to a black screen or restart. It is recommended to enter the application management to find and uninstall incompatible software, clear the memory, and upgrade the third-party application app and system software to the latest version to see if it can be solved.

4. Confirm whether the non-Huawei official system is installed.

Unofficial system will affect the stability of mobile phone and lead to the abnormality of mobile phone. It is recommended to bring the purchase voucher to Huawei Customer Service Center to restore or upgrade the system.

5. After confirming whether a certain software is installed or clicking an unknown link, the mobile phone is abnormal.

You can enter safe mode and uninstall previously installed software.

Enter and exit safe mode:

EMUI 9. 1 below: Press and hold the volume button at the same time during the boot process to complete the boot. When the words Safe Mode appear in the lower left corner of the screen, it means that the mobile phone has entered;

EMUI 9. 1 and above: Press and hold the power button and the volume up button at the same time during startup until the recovery mode appears, and select the safe mode;

Mate30 Pro & ampMate30 RS: Press the power button for 5 consecutive times to enter after the mobile phone starts shaking;

Restart the phone to exit safe mode.

6. Confirm whether the system file has been deleted by mistake, resulting in abnormal mobile phone.

When the system is running, the corresponding file can't be found, which leads to confusion and mobile phone failure. Try to restore the mobile phone system version through Huawei Mobile Assistant or eRecovery.

If the high-definition icon can be displayed normally before the mobile phone is repaired, but it cannot be displayed after the system is repaired, it is recommended to unplug the SIM card and replace it with another operator's SIM card. After registering to the network normally, unplug the SIM card and insert the problematic SIM card into the mobile phone.

7. After confirming whether the microSD card is installed, the mobile phone is abnormal.

It is recommended to check whether the problem still exists after plugging and unplugging the microSD card again. If the problem does not exist, it may be a poor contact. If the problem still exists, it may be that the microSD itself is damaged or incompatible with the mobile phone system. It is recommended to replace the high-quality microSD card.

8. Still can't solve it?

If the problem still exists, it is recommended to back up the data (QQ and WeChat need to be backed up separately), and then take the purchase voucher to Huawei customer service center for testing and processing.
