Install for the Floating Keyboard
If you sometimes have issues typing on your Galaxy A's display, you're going to really like this new feature.
Samsung's brought back a floating keyboard in Android Pie. If you're unfamiliar, it allows you to move the keyboard around the screen in order to find a sweet spot for two-handed typing. You can use the floating keyboard in most applications.
So if you've got small hands or typing just feels awkward on your display sometimes, you'll want to give Android Pie a shot.
It'll be particularly helpful to those who own bigger models like the Galaxy A8+ and Galaxy A9.
