What is Bixby button? Why may you want to disable Bixby button in Galaxy S9 and S9+?

Since Galaxy S8 (and S8+), Samsung added a dedicated button for Bixby with the hope of boosting the usage of Samsung’s AI assistant.

As shown in Galaxy S9 and S9+ layout, Bixby button is located on the left side of the phone below the volume keys.

By default,

If you press the Bixby button on Galaxy S9 or S9+, the phone will open Bixby Home.

How to use Galaxy S9 home screen landscape mode?

simon · 8 Comments

Samsung added the Galaxy S9 home screen landscape mode in Galaxy S9 and S9+.

You can change Galaxy S9 home screen to landscape orientation when you hold Galaxy S9 and S9+ horizontally. Of course, this also applies to Galaxy S9 apps screen (app drawer), which essentially is a special home screen.

This Galaxy S9 guide explains what Galaxy S9 home screen landscape mode is, how to enable and disable Galaxy S9 home screen landscape mode, and how to use Galaxy S9 home screen landscape mode.

Update: in Android Pie update for Galaxy S9 and S9+, you can use the rotation toggle button to quickly change and lock screen orientation, including the home screen. You may check this guide on using the rotation toggle to change and lock the Galaxy S9 screen orientation.

In addition, you can also lock the layout of Galaxy S9 home screen in Android Pie update as explained in this guide.

What is Galaxy S9 home screen landscape mode?

By default, the home screen (and apps screen) was always in portrait mode on most Android phones even if you hold the phone horizontally, and if you turn on auto-rotate.

So, it is hard to use the home screen in landscape mode, and you may have to hold the phone in portrait orientation to use the home screen and apps screen.

Please do not confuse this limitation in home screen with the auto-rotate.

Most apps including system apps like Settings support landscape mode for a long time. When you turn on auto-rotate, you can use most apps in the landscape orientation.

In Android tablet, since Android Honeycomb 3.0, the home screen landscape mode has been supported.

However, on the phone, the home screen landscape mode is still new.

The larger screen aspect ratio beyond 16:9 in many recent flagship Android phones exacerbates the implementation of landscape mode for the home screen. The screen simply looks too narrow for the icons.

Anyway, Samsung now offers the option to use Galaxy S9 home screen landscape mode in Galaxy S9 and S9+.

This means the Galaxy S9 home screen can automatically rotate to landscape mode when you hold the phone in landscape position.

Undoubtedly, the app icons and widgets in Galaxy S9 home screen will be re-organised in landscape mode. Simple rotation is not enough due to insufficient height in the landscape mode.
