How does Huawei set a window to pop up at the top of the screen when receiving SMS?

First, confirm the open license notice.

Enter settings, search application management, find information, click notification/notification management, and turn on the notification permission switch. If it is open, please close and reopen it and try again.

Second, there is no banner notice after receiving the message.

Please make sure that the information banner switch is turned off.

Enter settings, search and enter application management, find information, click notification management/notification, select the corresponding card 1/ card 2 in the category, and turn on the banner switch.

Third, clear the data.

It may be that the information data is abnormal. I suggest you try to clear the data. The operation method is as follows:

1. Go to Settings, search Application Management, find the information, click Save > Delete Data, then restart the phone and try again.

2. Try to restore all settings: Go to Settings, search to restore all settings, and then click the Restore All Settings option.

Warm reminder: the path of EMUI 5.0 is Settings > Advanced Settings > Backup Reset. When the reset settings are used, the switch of the application avatar will be turned off, resulting in the loss of the application avatar data. Please back up the application data before this operation.

After all the settings are restored, when you set the face or fingerprint to unlock, you need to enter the application lock password to verify the binding. If you forget the application lock password, please try to retrieve it.

If the above method has not solved your problem, I suggest you back up your data in advance (third-party applications such as QQ and WeChat need to be backed up separately) and take the purchase voucher to Huawei customer service center for testing.
