My Xiaomi mobile phone sent a text message to someone, and then it disappeared. What happened?

1. The user has turned on the private short message function, that is, after sending a short message to the other party, the short message will be automatically hidden; You can enter the SMS interface, hold down the screen and pull down. After the privacy SMS interface pops up, cancel the privacy setting.

2. Users install third-party software, which affects the normal function of SMS. For example, if you use the privacy protection function of other security software, the sent SMS will be automatically hidden, and you can cancel the protection by entering the setting interface of such software.

3. There is a problem with the mobile phone system, which leads to the loss of short messages. You can try to restart the phone to solve it. If necessary, the mobile phone system can be restored to the factory setting state or upgraded to the latest version.
