How to connect Xiaomi phone to Samsung TV via Wi-Fi: all ways and solutions to problems

Wirelessly streaming a screen from Xiaomi to Samsung TV seems like a simple task — until you encounter bugs like “Device not found” or constant connection breaks. The problem is that manufacturers use different protocols: Miracast (from Xiaomi), Wi-Fi Direct and Smart View (from Samsung), and their compatibility depends on the firmware version, TV model and even regional settings.

This article features three working methods of connectivity (including hidden compatibility mode for older Samsung models), protocol compatibility table, and solutions for the 5 most common bugs. If your Redmi Note 12 doesn’t see the 2020 Samsung QLED or the picture is slowing down, here’s the reason and fix. For convenience, we added interactive checklists and a survey at the end to see what worked for other users.

1.Preparation: What to check before connecting

Before attempting to connect devices, make sure they meet the minimum requirements:

• 📱 Smartphone Xiaomi: version MIUI 12+ (Miracast may not work on older firmware. Check version: Settings → The phone. → Version. MIUI.

Critical: Turn off your smartphone VPN and temporarily deactivate ad blockers (such as AdGuard or Blokada) that can block service packets needed to detect devices. Also check that the TV is on Network Sharing (Settings → General → Network → Device Access).

💡

If you have a Samsung TV with Tizen operating system version below 4.0, update the firmware through Settings → Support → Software Update. Without this, Smart View will not see Xiaomi due to the outdated protocol stack.

Method 2: Screen Mirroring (Miracast) - universal method

It's the standard wireless broadcast protocol that most devices support, and it's called Screen Mirroring (or Wireless Display) on Xiaomi, Screen Mirroring or Smart View on Samsung, and the main advantage is that it doesn't require internet, it works over Wi-Fi Direct.

Step-by-step:

1. On Samsung TV: Open Settings → Connections → Screen Mirroring (or Smart View on the remote, click Source → Screen Mirroring).
2. On Xiaomi: Open Settings → Connections & Sharing → Wireless Display (or Screen Mirroring in the notification curtain). In the list, find the name of your TV (such as Samsung QE55QN90B) and tap it.

Confirm the connection on both devices (entry may be required) PIN-TV-code).

Make sure Screen Mirroring | is on TV

Check that your smartphone and TV are on the same Wi-Fi network (or are using Wi-Fi Direct)|

Disable VPNs and ad blockers |

Reboot the router if the devices can’t find each other|

Update your firmware on your TV if Tizen is below 4.0-->

If the phone screen is not displayed or the broadcast is interrupted, try:

• 🔄 Reboot both devices.
• 📶 Reconnect to Wi-Fi (sometimes it helps to change the router channel from 2.4 GHz to 5 GHz).
• 🔧 On Xiaomi, in Screen Mirroring settings, enable Show Devices without Miracast (if any).

3. Method 2: Smart View (only for Samsung TV with Tizen 5.0+)

Smart View is Samsung’s proprietary technology that allows you to not only duplicate the screen, but also manage content from the phone (for example, play video on TV directly from the gallery).

How to connect:

1. On TV: Run the SmartThings app (if not, download from the Samsung App Store). Select Add Device → Phone or tablet.
2. On Xiaomi: Download the SmartThings app from Google Play. Sign up (you can use Google or Samsung Account). From the main menu, click Add Device → TV and select your model.

Follow the instructions on the screen (scanning may be required) QR-TV-code).

The advantage of this method is the stability of the connection and additional functions (for example, using the phone as a remote control).

• 🚫 On some Xiaomi models, for example, POCO X3) SmartThings may not see the TV. The solution is to use Screen Mirroring (mode 1).
• 🔒 You need a Samsung account to work, without it, only basic functions are available.

Method 3: Wi-Fi Direct – Manual connection (for experienced)

If the first two methods didn’t work, try connecting devices directly via Wi-Fi Direct, a trickier way to do this, but often saves on older Samsung models (2016–2018) or when Miracast is in trouble.

Instructions:

1. On Samsung TV: Settings → Network → Wi-Fi Direct → Enable Network Name (e.g. DIRECT-SamsungTV-XX:XX) and Password (if required).
2. On Xiaomi smartphone: Settings → Wi-Fi → Additional → Wi-Fi Direct Find the TV network and connect to it.
3. Return to Settings → Connections & Sharing → Wireless Display and select the TV manually.

Importantly, in this mode, the smartphone will not have access to the Internet, because it is connected directly to the TV, and to get back the network, you will have to switch between Wi-Fi Direct and the main access point.

💡

Wi-Fi Direct is the only working way for Samsung’s J series (2015–2016) TVs that don’t support Miracast or Smart View.

5. Compatibility table: which way to choose for your model

Not all Xiaomi + Samsung combinations work equally well, and the table below shows the proven options:

If your model is not in the table, check out the Tizen version:

Settings → Support → About the software

On versions below 4.0, you will need to use Wi-Fi Direct or an external adapter.

6. Problem Solving: 5 Errors and Correcting Them

Even with the right settings, the connection may not work.

⚠️ Note: If after connecting the phone screen is displayed with artifacts or “breaks” video, try in the settings Screen Mirroring on Xiaomi to reduce the resolution of the broadcast to 720p or disable the option of hardware acceleration.

• 🔴 Error: “Device not found” Check that Screen Mirroring is on TV → General. → External Devices: Restart the router (sometimes) DHCP fails IP-Addresses for Wi-Fi Direct. On Xiaomi in the developer settings (Settings) → The phone. → Version. MIUI → 7 times tap) turn on debugging over Wi-Fi.
• 🔴 Lags and stutters Video Switch router to 5 GHz channel (less interference). Close background apps on your phone (especially messengers and streaming services). In Screen Mirroring settings, select Game mode (reduces latency).
• 🔴 No sound when broadcasting on Samsung TV Check that the settings are → Sound. → Sound output selected by TV Speakers. On Xiaomi in the notification curtain during the broadcast, click on the Screen Mirroring icon and select Transmit the Sound.

If nothing helps, try a hard reset of network settings on your TV:

Settings → General → Reset → Reset Network settings

After that, you will have to reconnect to Wi-Fi.

7. Alternative methods: if nothing works

If all methods are exhausted and the connection still fails, consider these options:

• 📱 Google Chromecast: Connect the adapter to the port HDMI On Xiaomi, install Google Home and follow the setup instructions. Plus: works with all apps (YouTube, Netflix). ~2 seconds.
• 🖥️ Cable USB-C → HDMI: Suitable for Xiaomi with DisplayPort Alt Mode support (e.g. Xiaomi) 13 Pro, Redmi K60). We need an adapter. USB-C to HDMI (cost 500 ₽). Plus: no lags, full resolution 4K@60Hz.
• 🌐 DLNA (Photo/video/music only: Turn on TV DLNA (Settings → General. → On Xiaomi, use the Mi Home app or BubbleUPnP. Minus: does not broadcast the screen, only files.

For 2015 and older Samsung TV owners, the only reliable way to buy an external adapter (e.g., Xiaomi Mi TV Stick or Amazon Fire TV Stick) is to support Miracast and Google Cast, bypassing the limitations of older models.
