What if the SMS can't pop up?

Taking Huawei P40 and EMUI 10. 1.0 systems as examples, the reasons why SMS cannot be displayed are as follows:

1. Check whether the mobile phone has downloaded third-party software, such as security guards. It is possible that the software intercepted the message. It is recommended to uninstall.

2. Verify whether the SMS blacklist function is set in the mobile phone.

3. Check the mobile phone notification settings, whether SMS notification is turned on and whether the notification mode is set to pop-up.

4. If all methods fail, it is recommended to back up the mobile phone data and restore the mobile phone to the factory settings.

If the notification reminder function is turned off, just turn it on. First find the system setting options, open them, find applications and notifications, and then look at notification management after entering. Turn it on and see if the switch behind "Information" is off. If "Closed" is displayed, just open it. After opening it, you can successfully remind the information.

This answer applies to most brands of mobile phones such as Huawei, Apple, Xiaomi and OPPO.
