Huawei's mobile phone occasionally has information sound, but there is nothing to show. How to deal with it?

If your Huawei mobile phone occasionally has information sound but no display, you can try the following solutions:

Check the notification settings: Make sure your mobile phone notification settings are correct. Open the settings of the mobile phone, find the notification settings or application management, and check the notification rights and settings of each application. Make sure that the application you want to receive notifications is allowed to send notifications.

Clear the application cache: Sometimes the cached data of the application may cause problems. Try clearing the cache for a specific application by going to Settings, finding Application Management, selecting the relevant application, and then clicking the Clear Cache option.

Check for application updates: Make sure your application is the latest version, and outdated applications may cause problems. Open the App Store and check if there are any application updates available.

Restart your phone: Sometimes restarting your phone can solve a temporary problem. Try restarting your Huawei phone to see if the problem still exists.

Restore factory settings: If all the above methods fail, you can consider restoring factory settings. Please note that this will erase all data on your mobile phone, so please make sure to back up important data in advance. Find the "System and Reset" option in the settings, select "Restore Factory Settings", and then follow the phone prompts to complete the operation.

If the problem still exists, it is recommended that you contact Huawei Customer Service Center or go to the nearest Huawei authorized service center for further technical support and help.
