To enable landscape on home screen and app drawer screen you need to be on the latest version of the software particularly if you own an S8. S9 and S9+ users will have it by default. You can check it by going to Settings > Software Update. If there’s an update available then download and install it. Once you do that go right ahead with the steps below to enable landscape mode in home screen on Galaxy S8/S9.
Use Galaxy S8/S9 Home Screen In Landscape Mode
Open Settings.
Under Settings, select Display.
Next, tap on Home screen.
In Home Screen settings you will see Portrait mode only option. Tap on it to disable portrait only mode.

This will also work for app icons and app drawer screen.

Then either I had to somehow manage using the screen with portrait orientation while the phone was kept horizontally or simply hold the phone vertically to use it and then switch back to landscape later. However, all of this is now a thing of the past with the latest option. How is it useful to you? Let us know in the comments down below.
