Install for the Floating Keyboard
The Galaxy S9's Android Pie update has a floating mode for the stock Samsung Keyboard app. If this sounds familiar you probably had a Galaxy device running Android KitKat.
Samsung devices running Android KitKat had access to a useful floating keyboard. For whatever reason, Samsung decided to remove the feature in Lollipop, Marshmallow, Nougat, and Oreo.
Fortunately, the company's brought the feature back in Android Pie and those of you who struggle with the size of the Galaxy S9's display should find it pretty useful.
Android Pie's floating keyboard allows you to move the keyboard around the screen in order to find a sweet spot for two-handed typing.
So if you've got small hands or typing just feels awkward on the Galaxy S9, try the Android Pie and enable the floating keyboard. It's available in all applications.
