How to delete the SMS sending record of Samsung mobile phone?

To delete the SMS record in the mobile phone, I suggest you: under the standby page-click on the mobile phone-record-click on the option box marked with a corner in the upper left corner (all calls are displayed by default, and the display here will be different if you have changed the viewing mode of the call recording point before)-select the viewing mode of the call recording point as All Information-click on the mobile phone-menu key (three dot icons in the upper right corner)-Delete.
