Apple 1 1 cannot receive information.

Solution 1: Check whether the application allows notifications.

If there is a problem that no new messages are notified after the screen is locked when using the iPhone, it is likely that we have not turned on the notification function of this application. We can turn on the notification function of the application in the settings of the mobile phone.

The setting method is as follows:

Step 1: On the iPhone's desktop, find the phone's setting options and click Enter.

Step 2: After entering the phone setting interface, find the notification option in the interface and click Open.

Step 3: After entering the mobile phone notification interface, find the application that cannot receive new message notification in the interface, and click Open.

Step 4: After entering the notification setting interface of the application, find the notification permission function in the interface, and slide the switch on the right side of the function to open it. When the switch turns green, it means that the function has been successfully turned on.

Step 5: After the permission notification function of the application is turned on successfully, you need to check the screen lock option in the reminder style of the interface.

Step 6: If you want the notification reminder of new messages to be displayed continuously, find the banner style option in the interface and set this option to continuous.

Solution 2: Check whether to open the notification center.

If there is a problem that there is no notification of new messages after the screen is locked during the use of iPhone, then it may be that we don't have the notification center function when the phone is locked, so just turn on this function.
