I received three messages at the same time. Why didn't a message appear?

Generally speaking, SMS is the software that comes with the mobile phone system. Take Android as an example. Most domestic manufacturers do not use Android system directly, but make a new version based on Android system in magic change. This version will protect some system software, and users cannot install or uninstall it.

But after all, SMS is also a kind of software. If we manually turn off the corresponding permissions, it will not be displayed normally. Although the mobile phone will receive a text message, there will be no prompt. If we turn on the permission to allow notification, the mobile phone will be notified when it receives the text message. If the priority display is set to on, the short message notification will be placed above other messages, ranking first. In addition to these functions, most mobile phones also have privacy protection for SMS notifications. When turned on, the notification will only display the notification in the unlocked state, but will not display the short message content, and will not be displayed normally until the mobile phone is unlocked.

Second, the blacklist

In addition, some mobile phones also have the function of "blacklist" or "rejecting calls or text messages from strangers". If the user sets this function himself, some short messages will be automatically intercepted. However, some mobile phones can set the priority of SMS notification. If it is set to General, when multiple SMS messages are received at the same time, the notification may not be displayed.

Third, third-party software interception.

In addition to the limitation of system authority and the function of SMS itself, there is also a situation that it is restricted by third-party software. Third-party software, such as 360 security guards and mobile phone version of computer housekeeper, all have functions similar to SMS interception, and such interception functions are only connections and will not be deleted.

Some powerful interception software will even help users display all kinds of short messages in different categories. When we receive a text message, the mobile phone will not display it. Most likely, the intelligent identification function of third-party software will treat it as unimportant short messages or spam messages and directly block the notification.

The solution is also simple. Turn off the permissions of this kind of software, or simply uninstall this kind of software. However, some software comes with the mobile phone system. Unless it is root, it cannot be uninstalled actively. You can only find the relevant settings and then close them.
