What to Do with Huawei Mobile Phone Black Screen?
2023-06-17

If your Huawei mobile phone has a black screen during use, please troubleshoot according to the following methods:

First, Check whether a fault occurs in the following scenarios

1.The screen is black during a call. In order to increase the battery life of the phone, if the distance sensor is blocked during a call, the device will automatically turn off the screen, and turn on the screen again after moving away.

2.The black screen appears when the phone is dropped or bumped. It is recommended that you bring your purchase certificate to the nearest Huawei customer service center for maintenance.

3.Reach the set sleep time. When the sleep time is reached, the screen will dim first and then turn off automatically. You can press the power button to turn on the screen again.

4.If the ambient temperature is too high or too low, the device will automatically shut down and the screen will be black. At this time, please wait for the device to return to normal temperature before using it. It is recommended that you try to keep the device at an ambient temperature of 0°C - 35°C to avoid this problem and reduce battery loss.

Second, try to solve it in the following ways

1.Force restart the device

It is recommended that you force restart your device. If you cannot restart or the black screen still appears after restarting, it may be a hardware failure. Please back up your data (third-party applications such as QQ and WeChat need to be backed up separately), and then bring your purchase certificate to Huawei Customer Service Center for repair.

2.Clean up the device space

(1) Clean up background applications. Multiple applications running in the background will take up too much memory or other resources, and abnormalities may occur when the device is overloaded. It is recommended that you try to avoid running multiple applications at the same time.

(2) Clean up the storage space, it may be that insufficient storage space leads to low performance. It is recommended that you use the phone manager to clean up the storage space of the device and uninstall apps that are not used frequently.

3.Check whether the memory card (SD card)/NM card is installed

Please reinsert the memory card/NM card and check whether the problem exists. If the problem does not exist, it may be a bad connection. If the problem persists, the card itself may be damaged or not compatible with the system.

4.The system may be damaged

The system may be damaged by mistakenly deleting system files or installing an unofficial system. Please refer to the following methods to use Huawei Mobile Assistant to repair the system:

(1) Go to the official website of Huawei Mobile Assistant, download and install the latest Windows version of Huawei Mobile Assistant.

(2) Open Huawei Mobile Assistant, click System Repair in the lower right corner of the page.

(3) When the phone is turned off, connect it to the computer via a USB data cable, and then press and hold the volume down button and the power button of the phone at the same time.

(4) After the phone enters the FastBoot mode, Huawei Mobile Assistant will prompt "Successfully entered the system repair mode", click to start repairing.

(5) After the repair installation package is downloaded, it will be installed automatically. Please do not disconnect the USB connection during this period. The whole process will take some time, please wait patiently. After the system repair is completed, the mobile phone will automatically enter the system update mode, and the mobile phone will automatically restart after the system update is completed.

Warm reminder: During system repair, please do not disconnect the USB connection.

If the repair fails, please back up your data (QQ, WeChat and other third-party applications need to be backed up separately) and bring your purchase certificate to Huawei Customer Service Center for repair.

Warm reminder: Detecting and repairing the system version of the device may cause data loss. If your device can enter the system normally, please back up the data immediately.
