Letv 1s SMS icon is missing. What if I can't send and receive text messages?

You tried to click Settings-Application Management-Desktop-Clear Data.

How to solve the problem of mobile phone desktop icon missing;

Initially, the software may be hidden. It is suggested to open the application-menu-show hidden applications-and see if the software that is not displayed is checked (if it is checked, it will not be checked);

Check whether the icons are grouped into other folders. If all the above operations fail, it is recommended that you back up your mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (enter mobile phone settings-reset-restore factory settings);

If the problem of restoring factory settings still exists, it is recommended to send the mobile phone to the nearest Samsung service center for testing and further processing.
