How to use Laban Key: Vietnamese Keyboard

To begin using Laban Key, you will need to install it on your Android phone or tablet.

When you open the app, you will be greeted by the main screen, where you will be able to choose the input method that you want to use.

This will allow you to type Vietnamese in different ways, such as using the English keyboard, or using the one built into the Android operating system.

The Laban Key will automatically recognize the input method that you have chosen, and you will be able to type your Vietnamese words in the language that you have chosen.
