If you own a Samsung Galaxy S9, then you have placed a phone app on the home screen, through which you can make calls and view the call history.
Now it's possible that this phone app has suddenly disappeared from the Home screen. If the phone app is no longer visible on your Samsung Galaxy S9, you can usually add it again relatively easily.
The reason for this is usually the following:
If you have activated "Drawer" as the start screen style, i.e. the start screen and app menu are displayed separately on the S9 or S9 Plus, then it can happen that the phone app suddenly no longer exists on the start screen.
Usually you remove the phone app by mistake and then notice it later.
Add the phone app back to the Drawer - Help
You must therefore switch from the start screen to the App menu and search for the phone app there.
Press and hold the app with your finger until it lifts off and can be placed back on the start screen in the Drawer, i.e. in the lower part of the Home screen.
Release the app to finally place it back in the App Drawer.
You can then open the phone app on your Samsung Galaxy S9 from the home screen, make calls and view the call history.
