On the SMS page, delete all the read gray pages.

Mobile phone short message page, delete all the gray read:

In the use of HarmonyOS system, there is a problem that there is unread information in the information APP, but the unread information can't be found after opening the information APP. In the information APP, "All Read" is displayed in a gray unavailable state.

Severity: it does not affect the stability of the system, but affects the user's feeling (affects the system experience).

Guess the cause of the failure: First, read was selected in the status bar SMS notification prompt, and the variable value did not refresh to the latest value when reading data during the program operation, which belongs to the program bug. Second, the bug of data call in system operation.

I hope it can be improved in the latest system version and get rid of this bug that affects the experience.
