What is the black screen of mobile phone?

If you get a blank screen during use, please press and hold the volume down button+power button 10 second or press and hold the power button 10 second to restart the equipment forcibly (some models can be extended to 20 seconds, such as Magic V and Magic 4 series), and troubleshoot the equipment as follows:

1. Use your mobile phone to check for abnormalities while charging.

This situation will lead to overheating of the mobile phone, resulting in abnormality. I suggest you try to avoid playing with your mobile phone while charging.

2. Check whether incompatible applications are running.

Running multiple applications in the background will take up too much memory or other resources, and equipment overload may cause anomalies. It is recommended that you try to avoid multiple applications running at the same time.

Some third-party applications are incompatible with the system, which may lead to equipment crash, system jam, black screen or restart. I suggest you enter the application market to download the latest version of the application and update the equipment system to the latest version.

If the system keeps reporting errors and can't start normally, you can enter safe mode and uninstall the previously installed software.

Note: 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. Use the volume button to control the cursor to select the safe mode, and press the power button to enter; Restart the device to exit safe mode.

3. Check whether the basic service of Glory Wisdom Assistant is turned on.

Go to Settings > Smart Assistant > YOYO and suggest that there will be a pop-up window of "Open Basic Services of Smart Assistant", click "Open Now", and then restart the phone. If there is no "Open Basic Service of Smart Assistant" pop-up, it means that the basic service has been opened. Restart the phone and try again.

4. Confirm whether the unofficial system that is not the official system of glory is installed, which will affect the stability of the equipment and cause the equipment to be abnormal. It is recommended that you bring the purchase voucher to Glory Authorized Service Center for system recovery or upgrade.

5. Confirm whether an external memory card is installed. Please check whether the problem still exists after plugging and unplugging the external memory card again. If the problem persists, it may be that the memory card itself is damaged or incompatible with the device system. It is recommended to try to replace the memory card.

6. It still doesn't solve your problem. If the mobile phone can be turned on normally, please back up the data (QQ and WeChat are backed up separately) and go to the service center for testing and processing. Find the preset application of HONOR- My Glory App, open the service page, and click Quick Service > Store Service/Store Service/Service Store to query the nearby service centers. It is suggested that you call the service center in advance to confirm the business hours, so as to facilitate your travel.
