What is the reason for the black screen of honor?

There is a black screen when the mobile phone is in use. Please press and hold the volume down button+power button 10 second or press and hold the power button 10 second or more to forcibly restart the phone, and troubleshoot as follows:

1. Confirm whether there is any abnormality when using the mobile phone while charging:

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 to run incompatible applications:

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. Some third-party applications are incompatible with the system, which may cause the phone to crash and the system to get stuck, resulting in a black screen. It is recommended to enter the application market to download the latest version of the application and update the mobile phone system to the latest version. Remember to back up your mobile phone data before upgrading (third-party applications such as QQ and WeChat need to be backed up separately).

If the system keeps reporting errors and can't start normally, you can enter safe mode and uninstall the previously installed software. Enter and exit the safe mode: press and hold the power button and the volume up button at the same time during the boot process until the selection interface appears, control the cursor with the volume button to select the safe mode, and press the power button to enter; Restart the phone to exit safe mode.

3. Confirm whether an unofficial system is installed:

Unofficial system will affect the stability of mobile phone and lead to the abnormality of mobile phone. It is recommended to take the purchase voucher to the service center to restore or upgrade the system.

4. 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 the 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 repair, it is recommended that you unplug the SIM card and replace it with another operator's SIM card. After the mobile phone is registered to the network normally, unplug the SIM card and insert the problematic SIM card into the mobile phone.

5, still can't solve:

If the problem still exists, please take the purchase voucher to the service center for testing and handling. It is recommended that you don't click on unknown links when using mobile phones to prevent mobile phones from being infected with viruses. Enter Glory official website > Service Support > If you want to inquire about the service shop, you can inquire about the nearby service center. Before going to the service center, it is recommended to back up the materials in advance (such as QQ, WeChat and other third-party applications), bring the purchase voucher, and call the service center in advance to confirm the time, so as not to delay your time ~
