Xiaomi’s modern Smart TVs, which run on Android TV or Google TV, provide users with ample multimedia entertainment, including running demanding games. However, the standard remote control that comes with the device often proves not comfortable enough for full-fledged gameplay due to the lack of physical analog sticks and a limited set of buttons. It is in these situations that owners think about using their smartphone as an alternative game controller, turning a familiar communication device into a powerful control tool.
Using a mobile phone in conjunction with a TV opens up access to deeper control settings and allows you to use gyroscopes and accelerometers of a smartphone for games that require a device tilt. This solution is especially relevant for owners of Xiaomi Mi TV Stick, Box S and Mi TV line, where the search for compatible Bluetooth gamepads can turn into a lottery because of the characteristics of the drivers of the system.
Before you start setting up, you need to understand that there are two fundamentally different approaches: using the phone as a virtual remote with advanced functionality and emulating a real Bluetooth gamepad at the system level. The first option is suitable for navigating menus and simple games, while the second requires installing specialized software on both devices to ensure minimal input lag. Xiaomi is actively developing the ecosystem, but native support for smartphones as gamepads is limited, so we will have to resort to third-party solutions.
The Benefits of Using a Smartphone Instead of a Standard Remote
The main advantage of using a smartphone is its versatility and the presence of a touch screen that can display dynamic button layouts that change depending on the application running. Unlike a standard IR remote or a simple Bluetooth controller, the phone has a powerful processor that can process complex gestures and transmit data through high-speed Wi-Fi Direct or Bluetooth Low Energy protocols. This allows you to implement functionality that is not available for ordinary peripherals, such as displaying a game map or inventory directly on the phone screen while the TV displays the main picture.
Plus, the smartphone is always on hand, and you don’t have to look for a separate accessory or worry about buying batteries for an extra gamepad.The phone is regularly charged, and modern models support fast charging, which minimizes downtime. For Xiaomi Mi Box TVs, it’s also a way to get around the limitations of some apps that don’t work properly with standard remotes, requiring exactly mouse or touchpad emulation, which is ideally implemented through the smartphone screen.
⚠️ Note: When using your phone as a joystick over Wi-Fi, make sure both devices are on the same subnet (AP Isolation will block the connection between the TV and smartphone, even if they are connected to the same access point.
Another important aspect is tactile recoil. Modern smartphones are equipped with advanced vibrator motors that can transmit (feedback) in games that support this functionality through special intermediary applications. This creates an immersion effect comparable to expensive console controllers. However, it is worth considering that the constant operation of the screen and communication modules can quickly drain the battery, so it is recommended to keep the phone on charge during long gaming sessions.
Software solutions: controller applications
The most affordable way to turn a phone into a joystick for a Xiaomi TV is to install specialized apps from the Google Play store. The leader in this niche is already Google’s Android TV Remote Control app, which provides a stable connection and has a convenient touchpad. However, for games it is not suitable, so users often pay attention to solutions such as TV Remote Control, Universal TV Remote or specialized gamepad emulators like Bluetooth Gamepad.
The setup process usually begins with the installation of the selected application on the smartphone, after which you need to launch it and initiate the search for available devices on the local network. Xiaomi TV must be on and connected to the same Wi-Fi network. In some cases, the TV will be a request for confirmation of pairing, which you need to accept using the standard remote. Once successfully connected, the phone screen will turn into a control panel with navigation buttons, keyboard and, in some applications, virtual joysticks.
- 📱 Android TV Remote Control: Official solution with voice input and minimal navigation delay.
- 🎮 TV Gamepad: A specialty application emulating an Xbox or PlayStation controller via a Wi-Fi connection.
- ⌨️ Universal Remote: Combine that supports IR port (if you have it in your phone) and network management for old and new Xiaomi models.
Importantly, not all apps work equally well with the PatchWall shell used in Xiaomi TVs. Some emulators may not handle back or home buttons properly, which requires additional calibration in the app’s settings. It’s recommended that you test several options to find the optimal balance between functionality and interface usability specifically for your TV model.

To reduce input lag in Wi-Fi games, try to connect both your phone and TV to a 5GHz router. 2.4GHz is often overloaded by neighbouring networks, causing cursor jerks.
Setting up Bluetooth connection for games
For more serious games, where every millisecond of response counts, the Wi-Fi connection may not be stable enough, in which case Bluetooth is preferable. HID-There are emulation methods available for a device (like a mouse or keyboard) without root rights or specific software, and one of these methods is to use applications that create a virtual Bluetooth server on a phone that the TV sees as an external gamepad.
The pairing process begins by activating Bluetooth Visibility Mode on Xiaomi TV via Settings → Controllers & Accessories → Add Accessory. Simultaneously, an emulator app is launched on the smartphone that starts broadcasting the signal. The TV must detect the device with the name corresponding to the selected profile (for example, "Wireless Controller"). Once paired, the Android TV system automatically determines the device as a game controller and assigns the appropriate drivers.
The standard Android layout may not match the expected game. To solve this problem, we use button reassignment utilities such as Button Mapper or embedded tools in emulator applications. You may need to create a profile specifically for the game by assigning physical gamepad buttons to virtual buttons on the phone screen.
| Parameter | Wi-Fi (Applications) | Bluetooth (Emulation) | USB-modem (OTG) |
|---|---|---|---|
| Delay (Latency) | Medium (20-50 ms) | Low (10-20 ms) | Minimum (<10 ms) |
| Stability | Depends on the router. | Tall. | Maximum |
| Difficulty setting up | Low. | Medium | Tall. |
| Battery consumption | High-pitched | Medium. | Low (television charge) |
⚠️ Note: When using Bluetooth emulation on Xiaomi TVs with a small amount of RAM (1 GB or less), unstable system operation is possible. background emulation processes can cause slowdown of the Smart interface TV.
It’s worth mentioning that some advanced users use ADB (Android Debug Bridge) to hop input from their phone to their TV, a method that requires debugging via USB on the TV (in developer mode) and installing the appropriate server on a PC or directly on TV. The command looks like adb devices to check the connection, and you can use the adb shell input keyevent to emulate input, although this is the level for advanced modifications.
Using the telephone through USB-cable (OTG)
The most reliable, though least mobile, way is to physically connect your smartphone to your Xiaomi TV via a Xiaomi TV. USB-port (OTG). In this mode, the phone can be defined by the TV system as wired. HID-controller, if you use special applications that require root access, or if the phone supports the mode"USB Tethering in a specific configuration emulating a network adapter for command-dropping.
However, a more common scenario for USB — It's using your phone as a power source for a Bluetooth adapter, or using special applications that, when wired, minimize latency, and you need to turn on the developer mode to do that on your TV. This is done by repeatedly pressing the Settings item. → On TV. → Assembly (7 times).
☑️ Preparation for USB-connection
Once you activate debugging, connect your phone to the TV's USB port. The system can request debugging permission, which you need to confirm on your TV screen. Next, using applications like Remote ADB Keyboard or dedicated USB-enabled gamepad emulators, you can achieve almost instantaneous response. This is ideal for retro consoles running on your TV, where timing is critical.
It’s important to consider power consumption.The USB port on a Xiaomi TV usually delivers currents of up to 500mA, which may not be enough to run the phone’s screen and communication modules at the same time.It’s recommended to keep the brightness of the smartphone screen to a minimum or use apps that lock the phone’s screen, leaving only the touch layer to control active.
Solving delay and compatibility issues
Even when properly configured, users may have problems with de-synchronizing on-screen and phone clicks. The main enemy here is image buffering on the TV itself. Many Xiaomi models default to post-processing, which increases input lag. For games, you need to switch image mode to Game or Sports, and disable all improvements like noise reduction and dynamic contrast.
If you use a Wi-Fi connection, make sure the channel is not congested. In apartment buildings, the air is filled with neighbors' signals, which leads to the loss of data packets between the phone and the TV. Using a Wi-Fi analyzer will help you find a free channel or switch to 5 GHz if the router and TV support this standard. It is also worth checking whether the router is not worth the speed limit (QoS) for multimedia devices.
- 📉 Decrease in graphics quality: In the settings of the emulator on the phone, you can reduce the frequency of the sensor survey, which will reduce the load on the network.
- 🔄 Restart Services: Sometimes it helps to restart the service TV Remote Service in the settings of TV applications.
- 🔌 Disconnecting the superfluous devices: Turn off the TV extra USB-devices that may interfere with or consume the bus resource.
⚠️ Warning: Some antivirus programs and firewalls on smartphones may block outbound connections to the local network, considering them suspicious. If you have problems with connection, temporarily turn off network protection in your phone security settings.
Android built-in tools can be used to diagnose problems TV. Go to Settings. → Reference → Diagnostics of the network to check the quality of the connection. If the ping to the gateway is high, the problem lies on the router or Wi-Fi side of the TV module, not the phone. USB-a distance distance distance to the TV (to remove the antenna), can significantly improve the stability of communication.
Secret method of reducing delay
Alternative methods and cloud gaming
If it seems difficult to directly turn a phone into a joystick for native TV apps, you might consider an alternative path: cloud gaming. Services like GeForce Now or Xbox Cloud Gaming, run through a browser on a Xiaomi TV or installed via a mobile phone. APK-The file, often with its own smartphone controller apps, in which the phone connects directly to the game server, and the TV acts as a monitor that broadcasts the video stream.
This approach takes the entire load off the TV's processor and eliminates the compatibility issues of input drivers. The phone uses its own gyroscope and touchscreen to send commands directly to the game stream. This provides the best compatibility, but requires a very fast and stable Internet connection with low ping to the service provider's servers.
Also worth mentioning is the possibility of using the phone as a second screen for games run on a PC and broadcast to a TV via a Chromecast or Miracast, where the phone can act as a steering wheel or dashboard using an accelerometer to control cornering in racing simulators. Apps like Sensorium or PC Remote allow you to customize such scenarios with high accuracy.
💡
Using a smartphone as a joystick for Xiaomi TV is a trade-off between convenience and functionality: Wi-Fi is ideal for navigation, Bluetooth or USB for gaming, and for cloud gaming, the phone becomes a full-fledged controller through its own service applications.
