After the mobile phone was updated, the text message could not be viewed, but it flashed back soon after clicking.

1. This is an instant messaging service. After receiving the flash message, it does not need to be opened, and the information content is directly displayed on the screen of the receiver's mobile phone. After reading, the information is not automatically saved, but only partially saved manually. This service is only suitable for China mobile users to send to China mobile users.

2. Your mobile phone can only store a certain number of short messages, and the excess will be automatically deleted.

3. Mobile phone system or network failure, the message failed to be automatically saved.

4. SMS intercepted by mobile phone software cannot be opened directly in the main interface, and needs to be viewed in the software.

Handling suggestions:

1. You can try to delete other messages in your mobile phone. Maybe the disappeared text messages will pop up, but there is little hope.

I don't know what number you are using. Some numbers support online viewing of SMS details. Log in to the online business hall and try to print the SMS details.

3. Open the mobile phone related software, such as 360 Jinshan, to see if there are any short messages processed by the software.
