Sometimes you want to demo something from your phone to a wider audience, maybe at a presentation or a demonstration. You may want to do it live or just to record something from your phone to put in a presentation.
Vysor is a app in the chrome browser that allows you to do just that on any android phone. You need to:
Enable Developer tools on your phone
Then enable USB Debugging in the Developer tools section
Add the Chrome app – VYSOR and you should be good to go.
