How to Fix Screen Mirroring Not Working on Samsung

Last Updated on April 25, 2022 by Angelos Chronis

Screen mirroring is a feature found on most modern Android devices and especially on Samsung models. It allows the user to “mirror” their mobile or tablet screen on another, usually bigger, compatible screen; for example, the screen of a Samsung Galaxy onto a Samsung smart TV.

Usually, accessing this feature is as simple as the press of a few buttons; You activate screen mirroring, link your Sasung smartphone to a TV and that’s it, you should be able to see a copy of your phone’s screen on your TV.

However, things are not always that simple. Sometimes, for whatever reason, a Samsung phone or TV will be unable to mirror its screen. In this article, we will explore the various reasons why this could happen and figure out ways to solve them.

  • Select your TV.
