Why do you still display unread messages after reading short messages?

The reasons for displaying unread information are system errors and interference from third-party applications.

1. System error: Sometimes there will be some errors in the mobile phone system, which will cause the SMS status not to be updated correctly. In this case, you can try to restart your phone or clear the cache of SMS application to solve the problem.

2. Interference from third-party applications: Some third-party applications may conflict with SMS applications, resulting in incorrect message status display. You can try to disable or uninstall some recently installed applications and check whether the problem is solved.
