Need to screen mirror the new Samsung Galaxy S23? Check out our guide for the latest Samsung phone.
Note that the Samsung Galaxy S21 phone comes with a feature called Smart View to cast content to other displays. This is Samsung’s native screen mirroring technology that allows a phone or tablet to send content to a Samsung smart TV or another Samsung wireless receiver. When mirroring with the Samsung Smart View option, you can only mirror to other Samsung devices. To share content from your Galaxy phone to a non-Samsung device you will need to use a Cast option instead of Smart View or add Cast mirroring to Smart View.

How to Screen Mirror and Cast a Samsung Galaxy Phone
There are a few ways to do this on your Samsung Galaxy. This guide walks you through each:
1. Access Smart View in the Quick Settings Tray
Swipe down from the top of your screen to reveal Quick Settings. The Smart View icon may be here. The button looks like a play button surrounded by two semicircles. If you don’t see Smart View here, move to step 2.
2. Access Smart View by paging further into Quick Settings
When you open the Quick Settings tray, by default it displays an abbreviated view with only a single row of icons. You can pull the tray down again to reveal the extended view. This displays a full page of available Quick Settings options. Look for Smart View here or swipe to the right to reveal an additional page of Quick Settings options to find the icon.
If you still don’t see Smart View here, move to step 3.
3. Access Smart View by searching inside Quick Settings
If you can’t see a Smart View icon anywhere on your Samsung Galaxy phone, you can search for it. Swipe down from the top of your screen to reveal the Quick Settings tray and swipe a second time to reveal the extended view. Tap the search icon, which is the magnifying glass, and enter “Smart View.” The search results will then display the Smart View icon.
4. Select Smart View and choose a destination
Click Smart View and select a destination to mirror to. Remember, with Smart View you will only be able to connect to other Samsung devices.
However, Casting will allow you to connect to other device types. Read on to discover how to use Cast on a Samsung phone.

Use Cast to mirror Samsung Galaxy devices
You can use the Cast option to screen mirror your Samsung phone to non-Samsung devices, like a Mac or Windows computer screen (and many other devices). To Cast from a Samsung Galaxy S21, select or search for the Cast icon when you open the Quick Settings tray. The steps for finding the Cast icon are the same as the steps for finding the Smart View icon that we detailed above. After you select Cast, choose the destination you would like to mirror to.
