Check the USB connection and settings.
First of all, make sure that the USB connection between your Huawei mobile phone and your computer is good. Try replacing the USB cable or connecting to a different USB port to ensure that the connection is not the root of the problem. In addition, please make sure that the phone is set to "transfer files" mode, not "charge" mode.
Install the latest drivers.
Most mobile phone connection problems may be caused by missing or outdated drivers. Visit Huawei official website or the website of the driver manufacturer to download and install the latest driver. Please make sure to select a driver that is compatible with your phone model and operating system.
Update mobile phone system software
Upgrading the phone's operating system software may help solve the connection problem. Open the phone's setup menu and check if there are any available system updates. If there are updates, please download and install them. These updates may contain patches to fix connectivity issues.
Reinstall the driver
If the driver installation fails, you can try to reinstall it. First, uninstall all drivers related to Huawei mobile phones on the computer. Then download and install the latest driver again. Make sure to follow the instructions and prompts during installation.
Use third-party tools
If none of the above solutions can solve the problem, you can try to use some third-party tools to help you manage your mobile phone connection. For example, you can try using the mobile assistant or driver management tools to diagnose and solve connection problems.
