If you find that the drop-down shortcut bar is missing on the Huawei Mate 40 mobile phone, you can try the following steps to adjust the settings:
1. Pull down the notification bar: Slide your finger down from the top of the screen to see if only the notification is displayed, but not the shortcut bar. If this is the case, continue with the following steps.
2. Open the setting application: find and click the "Setting" application icon on the main screen.
3. Enter notification settings: In the settings page, scroll down and select "Notification and Status Bar" or similar options.
4. Select notification management: On the notification setting page, select the "Notification Management" or "Notification Center" option.
5. Enable drop-down shortcut bar: On the notification management settings page, ensure that the "drop-down notification bar style" or similar options are enabled. If it is disabled, turn it on.
6. Customize shortcut bar: If the drop-down shortcut bar is enabled but still invisible, you can try to customize the contents of the shortcut bar. On the notification management settings page, find the option of "shortcut box" or "shortcut bar" to ensure that the shortcut you need has been added to the shortcut bar. You can add or delete specific shortcuts to meet your needs.
If the above steps still fail to solve the problem, you can try restarting your phone, or consult Huawei's official website or contact Huawei customer support for more specific help and guidance.
