Use Virtual Keyboard
Vivid Unit doesn’t come with a physical keyboard, but it features a touchscreen display that allows you to input text through a virtual keyboard.
To use the virtual keyboard, you can simply tap on the keyboard icon located on the taskbar at the bottom of the screen. This will bring up the virtual keyboard, which you can use to type in text just like a physical keyboard. You can switch between letters, numbers, and symbols by tapping the relevant keys on the keyboard. To close the virtual keyboard, simply tap the keyboard icon on the taskbar again.
