Is the number displayed on the Samsung B8399 information label clear or closed?

According to the description, there will be a number in the upper right corner of the SMS icon, indicating that there are unread SMS messages in the mobile phone. It is recommended to enter the SMS, read the unread SMS and see if the number is cancelled.

If you have read all the short messages and the number is still displayed in the upper right corner of the short message icon, it is recommended to try:

Because there is no specific model of the mobile phone, take the Android operating system as an example.

1, Settings-Application Manager-All-Information-Clear Data.

2. Restart the phone.

3. If there are numbers in the upper right corner of the information icon, but there is no information to see, it is recommended to enter Settings-Developer Options-Close without keeping the activity.

4. Check whether the third-party SMS software is installed in the mobile phone. If installed, please uninstall and delete.

5. If the same problem still occurs, please back up the important data of the mobile phone and restore the factory settings: Settings-Reset/Privacy Restore the factory settings.

If the problem still exists after the above operation, please take the purchase invoice, maintenance card and machine to Samsung service center for inspection.
