Microsoft SwiftKey is a popular keyboard app on Android.
SwiftKey is also designed to learn predictive text suggestions from what and how you jot down.
One thing you could do to customize your keyboard further is to use a theme.
Tap on Themes in the SwiftKey app to configure the appearance of your keyboard.
The themes will open into the Yours tab by default.
This tab displays a list of your downloaded themes.
With the keyboard open you could instantly switch between your keyboard themes by tapping on them.
Use the keyboard icon in the bottom-right corner of the screen to test out your downloaded themes.
The Gallery tab is where you’re free to scroll through pre-configured keyboard themes.
Alternatively, you’re free to tap Close preview to close it and keep searching.
Tip: When you download a theme, it will be automatically applied.
Use the Gallery tab to search for a pre-configured theme that you like.
Delete themes you dont want any more by pressing and holding them in the Yours tab.
