Roku isn't just a versatile streaming media player — it is also a handy "projector" for displaying your phone's screen on a TV or other big screen.
Using the Roku's screen mirroring feature, you can display exactly what you see on your Galaxy S10 (or almost any other phone) on your TV. Your Galaxy S10 should be compatible with any Roku model that supports screen mirroring .
Before you begin, make sure that the phone and the Roku are connected to the same Wi-Fi network . If you're doing this at home, that shouldn't be a problem — they're probably already set up that way. If you're connecting to a Roku at a different location, though, make sure you're connected to the local Wi-Fi network.
1.Using your Roku remote, press the Home button. In the sidebar on the left, select "Settings."
3.Select "Screen Mirroring."
4.Select either "Prompt" or "Always allow." If you aren't concerned about someone gaining access to your Roku and sharing their screen without permission, "Always allow" is a convenient option.
5.On your Galaxy S10 , swipe down from the top of the screen to pull down the Notification center. Pull it down a second time so you can see three rows of icons.
6.Find Smart View. You may need to swipe to the second or third page of icons before you find it.
7.Tap "Smart View." After a few moments, all the nearby devices to which your phone can connect will appear in a list.
8.When you see it, tap the entry for your Roku .
9.If you chose to be prompted whenever trying to mirror to the Roku, go back to your TV screen and use the Roku remote to select "Always allow" or "Allow." After a moment, the Galaxy S10 will connect and display on your TV.
Your Galaxy S10 may ask if you want to change the aspect ratio to suit the TV— in other words, if you'd like to stretch out your phone's display to fit the TV screen. Choose whichever option you prefer.
