After adding the video lockscreen option from the Galaxy S9 to the Galaxy Note 8 and Galaxy S8/S8+. Samsung has now added support for home screen landscape mode to the Galaxy Note 8 and Galaxy S8/S8+ devices in the latest update of Samsung Experience.
Until now, Samsung’s latest flagship, the Galaxy S9 was the only one with support for home screen rotation feature.
You can check for the option on your device by heading to Settings / Home screen settings. You should see a new “Portrait mode only” option that you can enable if you want your Home screen to rotate to Landscape mode.
While not everyone has the feature yet, Samsung should roll it out to more users very soon. You can also download the APK from below link.
