Sending your Android device's screen to a nearby TV is useful when you want to share a video, play a game or view some photos from a new trip.
Google built screen mirroring, which Google calls Casting, for Android starting with Android 4.4.2 – released in 2013, so your current Android devices should all have Casting built-in and ready to go. At one time, Google updated a support page with devices that supported the feature, but the company stopped updating it about the time that Samsung released the Galaxy S7 . In other words, if you have an Android device built over the last three or four years, you should be good.
In addition to an Android device running Android 4.4.2 or later, you need aor a Chromecast compatible TV or other compatible display device as a ].
So how is it possible to throw the screen on an Android device to a TV? It's pretty simple, actually.
Before you begin, make sure your Android device is connected to the same Wi-Fi network as your Chromecast device. Then pull down from the top of the Android device's display to display the Quick Setup box.
Look for a button labeled Cast . (If not, press the pen icon to edit the Quick Settings box and add it.)
Press the Cast button and then select the device you want to use. All your Chromecast devices, including allwill be listed. Select your TV, and then a second or two later, your screen will appear on the TV.
Everything you do on your phone will be reflected on the TV until you turn off Casting via a message displayed as long as you throw.
