First off, press and hold the “Alexa” button on the remote and say “Screen Recorder“. Now, you will be directly taken to the app page. Open it and install the app.
You will get a prompt on your Fire TV Stick screen. Click on “Start Now“.
On the next page, select the device where you want to transfer the video and that’s it. Within seconds, the video will be transferred to your device.
So that is how you can record the screen on Fire TV Stick without much hassle. You just need to install the app, record the screen and transfer the video once you are done. In my testing so far, the quality of the screen recording has been pretty good and it didn’t slow my Fire TV while running in the background.
