This is cool! I just came across this tutorial for how to cast videos, pics and more, from your android phone to the Raspberry Pi and onto your TV or computer screen, using an app called Raspicast!
I know you can also do this from Kodi using an app on the iphone or android. I have Kodi installed on a Raspbian image with the Pixel desktop, on a Raspberry Pi 3. But, when I exit Kodi and switch back to the desktop, without rebooting, for some reason there is a lag when streaming Netflix or videos from other streaming sites. So this works better for me!
Here is the link to the instructions for setting up Raspicast.
