Mirroring your Samsung phone to a Roku TV lets you share photos, play mobile games on the big screen, stream apps not available on Roku, or give presentations directly from your phone.

This guide will show how to mirror Samsung phone to Roku TV and alternative methods for situations where Wi-Fi isn't available.

Step 2. On your Roku TV, go to Settings > System > Screen Mirroring. Set the mode to Prompt (to approve each time) or Always allow.

Step 3. On your Samsung phone, swipe down from the top of the screen to access the Quick Settings menu and tap the Smart View button.
Step 4. Select your Roku TV from the list to start the mirroring process.
Step 5. Once connected, your Samsung phone's screen will be displayed on your Roku TV. You can now enjoy streaming videos, apps, photos, and more on the big screen.

To connect your phone to your TV without Wi-Fi, you can use alternative methods like a mobile hotspot or HDMI cable. Whether you're looking to mirror your Samsung phone to a Roku TV or another device, these solutions allow you to enjoy your content without the need for a wireless network.
Way 1. Use a Mobile Hotspot
If your Roku TV and Samsung phone can't connect via a traditional Wi-Fi network, you can set up a mobile hotspot on your phone and connect both your Samsung phone and Roku TV to it. However, keep in mind that using your mobile hotspot may incur additional data charges depending on your mobile plan.
Step 1. Go to Settings on your Samsung phone and select Connections > Mobile Hotspot and Tethering.
Step 2. Turn on the Mobile Hotspot and set up the Wi-Fi network name and password.

Step 3. On your Roku TV, go to Settings > Network > Set Up Connection, select the Mobile Hotspot network you just created, and enter the password.
Step 4. After both devices are connected to the hotspot, you can follow the same steps for screen mirroring as mentioned in the previous section.
Way 2. Use an HDMI Cable
If you prefer a wired solution or have trouble connecting wirelessly, using an HDMI cable can be a quick and reliable option to mirror your Samsung phone to your Roku TV. Here's how to connect phone to TV with HDMI cable:
Step 1. Depending on your Samsung phone's port, you'll need either a USB-C to HDMI adapter (for newer models) or a Micro-USB to HDMI cable (for older models).
Step 2. Plug the USB-C or Micro-USB end of the adapter into your Samsung phone, and the HDMI end into one of your Roku TV's HDMI ports.

Step 3. Use your Roku remote to navigate to the TV input settings, then select the HDMI port to which your phone is connected.
Step 4. Your Samsung phone's screen will automatically appear on the TV. From here, you can easily mirror content, watch videos, play games, or browse photos directly on the big screen.
