How to make the phone crash?

If you use a Huawei mobile phone and it crashes during use, please check it according to the following methods:

1. Forced restart of mobile phone

Press and hold the power button 10 seconds or more (emui11.0&; HarmonyOS System Edition needs to hold down the volume down button and the power button at the same time (10 seconds or more) to restart the phone forcibly. If it cannot be restarted, please bring the purchase voucher to Huawei Customer Service Center for testing and processing. If it is possible to restart the recovery, it is suggested to continue the investigation according to the following scheme to avoid the phenomenon of jamming in use.

2. Using the mobile phone while charging may cause the mobile phone to overheat, leading to abnormality. I suggest you try to avoid playing with your mobile phone while charging.

3. Check the storage space of the mobile phone

Please check the remaining storage space of your phone. If the storage space is less than 10%, the system performance will drop sharply. It is recommended that you try to ensure storage space, and it is recommended to reserve 20% space.

View mode: enter the phone settings, search for storage, and view the available space and remaining space. If the remaining space is relatively small, it is recommended to open the mobile phone housekeeper, choose cleaning acceleration, and clean up some unused files or applications.

4. Confirm whether to run incompatible applications.

(1) Running multiple applications in the background will take up too much memory or other resources, and the mobile phone may be overloaded. It is recommended that you try to avoid multiple applications running at the same time.

(2) Some third-party applications are incompatible with the system, which may cause the phone to crash. It is recommended that you enter the application market to download the latest version of the application, and back up the data in advance (third-party applications such as QQ and WeChat need to be backed up separately) to update the mobile phone system to the latest version.

If the system keeps reporting errors and can't boot normally, you can enter the safe mode, then enter the phone settings, search and enter the application management, and uninstall the previously installed software.

Warm reminder:

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;

HarmonyOS system & ampEMUI 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.

5. confirm whether microSD is installed.

Please 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.

6. Confirm whether the system files have been deleted by mistake.

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.

Warm reminder: Restoring the version of mobile phone system through Huawei Mobile Assistant or eRecovery may lead to the loss of mobile phone data. If the mobile phone can enter the system normally, please back up the data immediately (third-party applications such as QQ and WeChat need to be backed up separately).

7. Check the system version

I suggest you check whether the version of the mobile phone system is the latest version, go to Settings, search for software updates, and then click Check for updates. If not, it is recommended that you back up the data in advance (third-party applications such as QQ and WeChat need to be backed up separately) and upgrade the system to the latest version.

Unofficial system will affect the stability of mobile phone, resulting in abnormal mobile phone. If you have installed an unofficial system, it is recommended that you bring the purchase voucher to Huawei Customer Service Center to restore or upgrade the system.

If the problem still exists, please bring your purchase voucher to Huawei Customer Service Center for testing and handling. At the same time, it is recommended that you do not click on unknown links when using mobile phones to prevent mobile phones from being infected with viruses.

Warm reminder: If the data has not been backed up before, there may be the risk of data loss when restoring and upgrading the version of the mobile phone system and testing it.
