The phone and message shortcut keys at the bottom of Samsung mobile phones are missing, how can I get them back?

Preliminary judgment may be that the software is hidden. It is recommended to open the application-menu-show hidden applications-check whether the software that is not displayed is checked (if it is checked, just uncheck it) .

Check whether the icons have been sorted into other folders. If none of the above operations work, it is recommended that you back up your phone data (phone book, text messages, multimedia files, etc.) and restore factory settings (enter phone settings - reset - restore factory settings).

If the problem persists after restoring factory settings, it is recommended to send the phone to the nearest Samsung service center for testing and further processing.
