Help, there is no text message on the mobile phone. Why does the SMS label always show 1?

If the number is displayed on the SMS icon of Samsung mobile phone and cannot be cancelled, please solve it as follows:

1. Turn off reservationless activities in the developer options, and turn off reservationless activities in the application-settings-developer options.

2. It may be caused by information data error. Click Application-Settings-Application Manager-All-Information-Clear Data.

3. Please update the mobile phone software to the latest version, and apply-Settings-System Update (pay attention to backing up the important data of the mobile phone).

4. If it doesn't work, please back up the phone data and restore the phone to the factory settings (Setup-Reset-Restore the factory settings).

If the problem still exists, please take the purchase invoice, maintenance card and machine to Samsung Service Center for inspection.
