    We have gathered the answer to all of your streaming questions. Simple, to the chase and detailed way of clarification.

Installation of apps on Amazon Fire TV Stick is an easy thing to do: You search the app market, choose the app and click install, job done! Sometimes installation encounters errors saying "the origin of this app is unknown" or "Publisher of the app is unknown". This usually happens when user tries to install an app from outside of amazon market. Here we show how to enable installation of these apps on Amazon Fire Stick.

When should "Apps From Unknown Sources" be enabled?

Generally this feature is needed when an app is being installed from within another app. For instance if you have the "Downloader" app, which is a downloader and installer app by itself, and you want to install an app using Downloader on your Fire Stick, then you are basically installing app from outside of Amazon market. This is when you need to enable this feature.


Since Amazon Fire Sticks come in two different kind of Old and New interfaces, we explain this in details for both:

-New Amazon Fire TV Interface (Version and later)

2-Now move right and select Device
