Huawei's mobile phone can't download HSBC in Hong Kong.

I understand your problem is that you can't download the application of HSBC in Hong Kong on Huawei's mobile phone. Please note that since your phone may not recognize the installation of this application, you need to follow the following steps:

1. Confirm that your phone has been allowed to install applications from unknown sources. You can find the "Safe" or "Source" option in the phone settings, and make sure that the "Unknown Source" option is selected.

2. Please make sure that you have downloaded the installation package of the HSBC application in Hong Kong. Please ensure that you have obtained the installation package of the application from an official or trusted download channel.

3. Try to open the downloaded installation package on your mobile phone. When you click on the installation package, your mobile phone should prompt you to install the application.

4. If your mobile phone prompts you to install the application, please follow the instructions on the screen, including agreeing to any permission request and confirming the installation location of the application.

5. If your mobile phone still can't install the application, please check whether your mobile phone has enough storage space and make sure there are no other problems with your mobile phone. If the problem still exists, you can try to uninstall some other applications or contact Huawei customer service for help.

If you still can't download the application of Hongkong and Shanghai Banking Corporation, please ensure that you have followed the above steps and try to download and install the application on other mobile phones. If other mobile phones can't download or install the application, it may be because there is something wrong with the application itself or it is not compatible with a specific device.
