SMS icon on Samsung mobile phone

If the icon of the software that comes with the mobile phone/tablet is lost, I suggest you: 1. If the software icon on the home screen is missing, please enter the application-just click the icon you want to add and drag it to the home screen. 2. If you don't find your own software icon in the application, please check whether the application is hidden: Application-Menu button-Show hidden application (supported by some models). 3. Check whether the application is disabled/closed: Standby-Application-Settings-Application Manager-All-Find the icon-Click Enable. 4. Back up data (contacts, text messages, photos, etc. ) and restore factory settings (Settings-Reset/Privacy-Restore Factory Settings). If the problem still exists, it is recommended that you take the machine, purchase invoice and warranty card to the local Samsung after-sales service center for testing.
