This article describes how to change the default keyboard on Android and how to switch between keyboards. The instructions below apply to smartphones running Android 10, 9.0 (Pie) or 8.0 (Oreo) and should work regardless of who made your Android phone: Samsung, Google, Huawei, Xiaomi, etc.
How to Change the Keyboard on Your Android Device
Once you’ve downloaded an Android keyboard, or even more than one, launch it to complete the installation. Most apps will walk you through the process of enabling a keyboard and setting it as the default, but it’s also easy to do this manually.
Scroll down and tap System > Languages & input. (On Samsung Galaxy smartphones, go to Settings > General management > Language & input.)
In the Keyboards section, tap Virtual keyboard. (On Samsung, tap On-screen keyboard, then tap the standard keyboard.)
