ADB via USB on Samsung Galaxy Note 12.1 running KitKat

Many of you already know that, but since it is easy to forget here is a reminder how to turn ON the

"{}Developer options"

on devices running Android 4.4.x KitKat

Go to: Settings > General (tab) > About device

tap few times on "Build number" until the "{}Developer options" show in the left menu.

In "{}Developer options" 

- select USB debugging

I also often keep these 2 options selected when I share the device screen in demonstrations:

- Show touches

- Show pointer location

You can see the infinite sign I drew with my finger

For the screen sharing and capture I use command line software called "droid@screen"
