Why is the SMS interface displayed every time the lock screen is reopened?

Hello, it is reasonable to say that the page you opened before locking the screen is a short message interface, so the page you opened after unlocking will be a short message page.

If the page opened before locking the screen is not a SMS interface, then the page opened after unlocking is not a SMS page.

If you think there is something wrong with your mobile phone, you can restore it to the factory settings, but before restoring the factory settings, you should back up the data to avoid data loss.
