Screen recording on Android TV is not an easy process as we have in our android devices. Google has removed the main essential component which is required for screen recording apps i.e. "draw over other apps" setting to stop apps from floating over the UI components in the TV interface. This is quite reasonable to prevent privacy hindrance of the user. But still, you want to record the screen of your Android TV then here are the steps that you can follow.
One of the most popular methods of recording a TV screen is mirroring the screen. But the recorded video from this app is very low in quality and resolution. Here are steps that you can follow to record the screen of your Android TV.
