USB-Direct connection allows you to stream video in high resolution. 4K, Hi-Res music and photos in original quality.
The process of connecting a smartphone to a Xiaomi Mi TV TV or Redmi TV Seems simple, but often hides technical nuances associated with file system formats and modes of operation USB-In this article, we will discuss in detail how to prepare devices, which cables to choose for stable data transmission, and what to do if the TV can not see the connected phone, understanding these principles will save you from unnecessary nerves and allow you to enjoy content instantly.
Equipment and preparation of devices required
Before you start the transfer procedure, you need to make sure that the right equipment is available. USB-cable is suitable for data transfer; many cheap cables that come with budget electronics are designed solely for charging and do not have internal lines for transmitting information. You will need a high-quality cable with Data Transfer support, preferably original or certified by your smartphone manufacturer.
It is also important to consider the state of ports. USB Type-C connectors on phones and USB Type-A on TVs wear out over time, which can lead to unstable contact. Before connecting, it is recommended to visually inspect the ports for dust, pile or oxidation. If the connectors are dirty, gently clean them with a dry soft brush or compressed air to ensure a reliable connection.
Particular attention should be paid to the version. USB. To transfer heavy files, such as movies to 4K, It is better to use standard cables. USB 3.0 and higher, which are often marked in blue inside the connector. Although the ports on Xiaomi TVs are most often standard 2.0, using high-quality cable minimizes the risk of data packet loss when reading the media library.
Setting up the USB mode on a smartphone
After the cable is physically connected to the TV's USB port and smartphone, a system notification should appear on the screen of the mobile device. By default, Android smartphones go into "Charge Only" mode for security purposes, which means that the TV will supply power to the phone, but will not gain access to the file system.
To change this setting, lower the notification curtain on your phone and click on the message “Charge via USB” or similar. You will see the menu of the choice of mode of operation. To correctly display files on your Xiaomi TV, you need to choose the File Transfer (MTP) or Photo Transfer (PTP) mode. MTP mode is preferred, since it allows the TV to see the folder structure and all types of files.
⚠️ Note: If you have chosen the mode MTP, But the TV still can't see the folder, try switching to mode. PTP. Some older TV models work better with the image transfer protocol, although it is less versatile.
In some cases, especially on smartphones with a MIUI shell or HyperOS, additional access confirmation may be required. The phone screen may have a request "Allow data access?" that needs to be confirmed. Without this step, the file system will remain locked to external devices, and the TV will display the drive as empty or not display it at all.
☑️ Connection check USB
Search and discovery USB-TV-storage
Once the smartphone is in the correct mode, you need to refer to the TV interface. Xiaomi remotes often have a separate button for quick access to the signal sources or application menu. Press the button with the image of the square with the arrow or the Input button to call the source list.
In the list that opens, select your smartphone. It can be displayed as “USB Device”, “Mobile”, or on a phone model (for example, “Mi 11” or “Redmi Note”). If the device does not appear in the list of sources, try to find and run the built-in Media Player or Explorer application in the TV application menu. In some versions of PatchWall firmware, the external drive appears automatically at the top of the interface.
When you first connect, Android TV can request permission to debug or access files. If a pop-up with a code or confirmation request appears on your TV screen, be sure to accept it using the remote, which creates a trusted connection between devices, which is especially important for stable operation during long-term viewing.

Reproduction of video, photos and music
The interface of the built-in player on Xiaomi TVs is quite minimal, but functional. Once you open the folder, you will see a list of files. The system automatically sorts them by type: video, images, audio. To start the file, you just select it and press the central OK button on the remote.
The built-in player supports most popular formats, such as MP4, AVI, MKV for video and MP3, FLAC for audio. However, if you are faced with a situation where the video is played without sound or the image has artifacts, this may indicate (not supporting) a specific codec built-in TV facilities.
To expand the capabilities, it is recommended to install the VLC for Android or MX Player app on the TV. These programs have their own codecs and are able to play almost any file format transmitted from the phone. They also allow you to customize subtitles, audio tracks and playback speed, which is often not available in a standard player.
⚠️ Note: When reproducing heavy 4K-High bitrate files through USB-The modem of the phone is micro-slow, and this is due to the limited read speed through the interface. MTP compared to the physical flash drive.
Use of Third-Party File Managers
Standard Android TV tools aren’t always easy to navigate through the complex folder structure of a smartphone. If the built-in Explorer seems limited, installing a file manager from the Google Play store on a TV is a great solution, the leader in this category is the X-plore File Manager or File Commander app.
These apps provide a dual-panel interface that allows you not only to view files, but also to copy them to the TV's internal memory. APK-The application file is directly from your phone to your TV. Just copy the installer from the smartphone's Download section to your TV memory and start installing it.
Another useful feature of third-party managers is the ability to sort files by size, date or type, which greatly speeds up the search for the desired content in the crowded memory of a modern smartphone.

Install the X-plore File Manager app on your TV, which lets you create FTP-server, which will allow you to transfer files from your phone to your TV without wires, being in the same Wi-Fi network.
Solving Problems with Device Recognition
The most common problem is that the TV can't see the phone. If you're convinced the cable is working and the MTP mode is correct, try restarting both devices. Sometimes the USB drivers on Android TV can freeze, and a simple reboot restores the port to normal operation.
Xiaomi TVs, like most Android devices, are great at reading FAT32 and exFAT formats. If your phone uses an internal file system that isn't visible as a standard storage device, the problem may be this. If you use a memory card on your phone, make sure it's formatted in a compatible format.
Another reason could be power shortage: a USB port on a TV produces limited current (usually up to 0.5A or 1A). If the phone is charging and transmitting data at the same time, it may not have enough power and will constantly reconnect, in which case it is better to disconnect the phone from the charger and rely only on the TV power, or use an additional power cable if possible in your configuration.
💡
If the TV stopped seeing the phone after updating the firmware, reset the USB settings in the Developer Menu on your smartphone or perform a full reset of the TV settings.
