Casting your Samsung phone to a Roku TV is easier than it sounds, but the best method depends on what you want to show and how smooth you want the experience to be. Whether you are mirroring your entire screen, sharing photos, or playing a video from YouTube, there are several reliable ways to get it done. This guide walks you through how to cast Samsung phone to Roku TV using built-in features and flexible third-party tools, with clear steps you can follow in minutes.
Method 1: Use Built-in Miracast
Smart View is the fastest way to mirror your Samsung screen to Roku when both devices are on the same Wi-Fi network. It mirrors everything on your phone, which makes it ideal for presentations, browsing, or showing apps that do not support casting.
What you need:
- A Samsung phone with Smart View: Most Samsung phones include Smart View by default. To confirm, swipe down to open Quick Settings and look for Smart View. If you see it there, your phone is ready.
- A Roku TV that supports screen mirroring: On your Roku TV, go to Settings > System > Screen Mirroring. If this menu exists, your Roku supports screen mirroring and can receive a Samsung screen.
- Both devices connected to the same Wi-Fi: Check the Wi-Fi name on your Samsung phone and compare it with the network shown under Settings > Network on your Roku TV. The names must match for the devices to discover each other.
How to cast from Samsung phone to Roku TV:
Step 1. On your Roku TV, go to Settings > System > Screen Mirroring.

Step 2. Set Screen Mirroring mode to Prompt or Always allow.
Step 3. On your Samsung phone, swipe down to open Quick Settings.
Step 4. Tap Smart View.

Step 5. Select your Roku TV from the device list.
Step 6. Confirm the connection on your TV if prompted.
When this Samsung-to-Roku mirroring works best:
- You want full screen mirroring, not just video
- You are sharing photos, web pages, or apps
- You prefer a built-in solution without extra installs
Keep in mind that Miracast mirrors your screen in real time, so performance depends on Wi-Fi quality.
Method 2: Use the PigeonCast App
If you are asking, how do I cast my Samsung phone to my Roku TV, my answer is using PigeonCast.

Why consider using PigeonCast:
- Works well when Miracast fails to connect

PigeonCast is practical if you often cast Samsung phone to Roku in different environments, such as offices or shared networks.
Method 3: Use a Streaming App
Streaming apps with built-in cast support offer the most stable experience for video playback. Instead of mirroring your phone, the TV streams the content directly.
How to cast Samsung to Roku TV using YouTube:
Step 1. Open the YouTube app on your Samsung phone.
Step 2. Make sure your phone and Roku TV are on the same Wi-Fi network.

How to Cast Samsung Phone to Roku TV FAQs
How do I cast my Samsung phone to my TV?
The easiest way is to use Smart View, which is built into most Samsung phones. Turn on screen mirroring on your TV, open Smart View from your phone's Quick Settings, and select your TV from the list. If Smart View is not available or unstable, using a supported streaming app or a third-party casting app like PigeonCast is another reliable option.
Why won't my Samsung phone connect to my Roku TV?
This usually comes down to connectivity settings. In most cases:
- The phone and TV are not on the same Wi-Fi network
- Screen mirroring is turned off or set to "Never allow" on Roku
- The connection was blocked during a previous pairing attempt
Restarting both devices and rechecking the screen mirroring setting on Roku often resolves the issue.
Why can't I cast to my TV from my Android phone?
Not all Android apps support casting by default. Some apps rely on Miracast-style screen mirroring, while others use app-level casting where the TV streams content directly. If casting does not appear in one app, try Smart View for full screen mirroring or switch to an app that includes built-in cast support.
Where is the cast button on Roku?
Roku does not have a system-wide cast button. Casting is initiated from your phone or app, not from the Roku interface itself. You will typically see a cast icon inside supported apps like YouTube, or you will connect through features such as Smart View on Samsung phones.
Why is my Roku not discoverable?
If your Roku does not appear as an available device, check the following:
- Screen mirroring is enabled under Roku system settings
- Both devices are on the same Wi-Fi network
- Your router is not using network isolation or guest mode
Once these are aligned, your Roku should become discoverable within a few seconds.
