Android device most time as we know comes in a full touchscreen platform, some also come with hardware keyboard but most of them are full touch screen.

The full touch screen makes it smarter and fun to use. But when it is full touch screen then we need to install keyboards as application, so we can interact with the device.

Picking a keyboard application depends on how compactable they are to your device and how they look.
