How to connect a Samsung phone to a TV Xiaomi Mi 4S: all ways with photos and videos

Connecting Samsung smartphone to the Xiaomi Mi TV 4S opens up a lot of possibilities: from viewing photos on the big screen to streaming video in resolution 4K But users often face compatibility issues, such as Miracast, which is not working because of different wireless protocols. HDMI-cables are not recognized without additional adapters. In this article, we will discuss all current ways of connecting, including hidden settings Mi. TV, which the manufacturer does not advertise.

The Xiaomi Mi 4S (L43M5-5ASU, L50M5-5ASU, etc.) has limited support for Wi-Fi Direct and DLNA standards compared to the brand’s flagship TVs. For example, when connecting via Screen Mirroring on the Samsung Galaxy S23 Ultra, you may need to force the “Old Device” mode on the Mi TV settings, otherwise the screen will flash or display with artifacts. We tested all methods on current MIUI 14 firmware (for phones) and PatchWall 4.0 (for TV) to ensure that the instructions are working.

If you've tried to connect devices before and you've had errors like "Device failed" or "Miracast is not supported," don't blame the technology. 80 percent of the time, the problem is with the wrong network settings, the outdated software, or the lack of adapter drivers, and then step-by-step guides with these nuances in mind.

1. Connect via Wi-Fi Direct (Screen Mirroring)

The most versatile method that does not require cables. Xiaomi Mi 4S supports the Miracast protocol, but with reservations: the maximum resolution during transmission is 1920×1080 (even if the TV is 4K), and the sound delay can reach 200-300 ms. First, make sure that both devices are connected to the same Wi-Fi network (or create an access point on the phone).

Instructions for Samsung (on the example of Galaxy S22):

• 📱 Open the Settings. → Connections → Screen Mirroring (or Smart View).
• 🔍 In the list of available devices, select your Xiaomi Mi 4S (The name will be in MiTV-format[letters/digits]).
• 🔄 If the connection is not established, go to Settings on the TV → The Internet and the Internet → Wi-Fi Direct and enable Allow All Devices".
• ⚙️ To reduce the lag in the TV screen settings, set the Image Mode: Game.

On the Xiaomi Mi 4S, the path to settings may vary depending on the PatchWall version:

Settings → Devices → Phone screen → Turn on Miracast

If the image “breaks” or the sound disappears after connecting, try:

• 🔌 Reboot the router (especially if it is dual-band – 2.4 GHz is more stable than 5 GHz for Miracast).
• 📶 Reduce the distance between devices to 3-5 meters.
• 🔊 In the TV sound settings, select Exit: HDMI ARC (even if the connection is wireless).

💡

If the phone screen isn’t showing up in full, tap on the Menu remote → Image → Screen size and select Just Scan (no cropping).

2. Connection to HDMI (adapter-wise USB-C/HDMI)

Modern Samsung Galaxy (starting with the S10) will require a USB-C → HDMI adapter with DisplayPort Alt Mode support. Important: cheap Chinese adapters often do not transmit sound or limit the resolution to 720p. We recommend original adapters from Samsung (EE-HG970) or certified by Anker.

Step-by-step:

1. Connect the adapter to the phone and HDMI-cable HDMI 2.0 on Mi 4S (port HDMI 1/ARC They may not recognize the signal).
2. On the TV, select the signal source: press the Input → HDMI 2 remote.
3. On the phone, the notification curtain will appear USB: Transfer images – click on it and select DeX Mode (for desktop) or Duplicate screen.

If the image does not appear:

• 🔄 Try another one. HDMI-port HDMI 3 on the Mi 4S Often conflicts with adapters).
• 🔋 Make sure the phone charges while you connect (some adapters require external power).
• 📱 In the phone settings, turn on for developers → Debugging by USB (Sometimes helps with recognition problems).

3. Connection via USB (MTP/PTP)

This method is suitable for viewing photos/video, but does not support screen duplication. Xiaomi Mi 4S recognizes Samsung phones as external drives, but only if the smartphone is enabled file transfer (MTP). For video in 4K or HEVC format, you may need to preconversion – TV does not always correctly play files with a bit rate above 50 Mbit / s.

How to connect:

1. Connect your phone and TV with a USB-A → USB-C cable (use the USB 3.0 port on the Mi 4S for faster speeds).
2. On the phone in the notification curtain, select File Transfer (not Charging).
3. On the TV, open the Files or Gallery app - the phone will appear as a removable disk.

Limitations of the method:

• ❌ No sound when watching video (sound is coming through the phone).
• ❌ Streaming services (Netflix, YouTube) are not working because of the DRM-defense.
• ❌ Maximum video resolution — 1080p (even if the file 4K).

4. Connect via Chromecast (Google Cast)

If your Xiaomi Mi 4S has Google Play Services installed (available on PatchWall firmware since 2021), you can use Google Cast to stream content. This method works more stable than Miracast, but does not support all applications. For example, Netflix and YouTube stream without problems, and TikTok or local video players do not.

Instructions:

• 📱 Make sure that the latest versions of Google Play Services are installed on your phone and TV.
• 🔍 On your TV, open the Google Cast Receiver app (if not, install it via GetApps).
• 🎯 In the app on your phone (like YouTube), click the Cast icon (in the top right corner) and select Mi. 4S.

List of supported apps for Google Cast:

💡

Google Cast consumes less phone resources than Miracast, but only works with a limited list of apps. For universal screen broadcasting, it is better to use HDMI or Wi-Fi Direct.

5. DLNA connection (for media files)

DLNA allows you to stream music, photos and videos from your phone to TV without duplicating the screen. On the Xiaomi Mi 4S, this feature is built into the Media Player app, but requires pre-configuration of the network.

How to set up:

1. On your phone, install the BubbleUPnP app (or use the built-in SmartThings on Samsung).
2. On the TV, open Media Player → DLNA and enable device detection.
3. In the application on the phone, select the file and click Play on → [Your Mi. 4S].

Supported formats for Xiaomi Mi 4S:

• 🎵 Audio: MP3, AAC, FLAC, WAV (supportive ALAC).
• 📷 Photo Photo: JPEG, PNG, BMP (supportive HEIF/HEIC Apple).
• 🎬 Video: MP4 (H.264), MKV (before 1080p), AVI (supportive H.265/HEVC containerized MOV).

💡

If the video is slowing down when playing over DLNA, convert it to H.264 with a bitrate not higher than 20 Mbps through the HandBrake program.

6. Solving common problems

Even with the right connection, there can be errors, and we've collected typical scenarios and ways to fix them:

If none of the methods worked:

⚠️ Note: Some of the firmware Xiaomi Mi 4S (Especially on modifications for China) Miracast support is disabled at the system level. → On TV. → The model, if the model ends -CN, You will need to change the firmware to a global one (-SU), But it voids the guarantee.

To diagnose problems with HDMI:

• 🔧 Check the cable on another device (such as a laptop).
• 🔄 Restart the TV by holding the power button on the remote for 10 seconds.
• 📡 Turn off all others. HDMI-devices (configures, sound panels) – they can conflict.
