Why is there always a short message prompt but no short message?

It is possible that the notification of an application has been turned off by the system, and you can't see it when it is notified. You can find it in the notification bar settings. If not, you can take the following measures: check whether the mobile phone is in mute or vibration state.

Because the repeated SMS reminder is turned on, the operation method is as follows: first unlock the phone and click Settings, as shown in the figure below. Enter Settings and click Notify, as shown in the figure below. Enter the mobile phone notification settings page. On the notification settings page, find and click the information, as shown in the figure below.

There are basically several reasons for this: 1 is some notification information. You can go to the notification bar and status bar in the settings, check the notification management, find the software that sends notifications, and turn it off by "ringing or allowing notifications". Some softwares have automatic reminders.
