Xiaomi smartphone owners often look for ways to improve the gaming experience by turning a mobile device into a full-fledged console. Using a physical controller such as the Defender Crusher allows you to feel the real return in racing, fighting games and shooters, where touch control often fails. The process of pairing devices does not require complex manipulation, but has its own nuances, especially when working with the shell of MIUI or HyperOS.
Proper joystick synchronization gives you access to retro console emulators and cloud gaming, which greatly expands the functionality of your phone. In this article, we will discuss in detail all the stages of connection, from enabling pairing mode to fine-tuning key emulation for games that do not support gamepads natively, you will learn how to avoid typical errors and ensure stable operation of the device.
Preparation of equipment and choice of operating mode
Before starting the procedure, make sure that your Defender Crusher's battery is sufficiently charged. Low charge can lead to an unstable connection or inability to enter Bluetooth search mode. USB-smartphone port or power adapter.
The key is to choose the right mode, as this controller supports multiple profiles. For Android smartphones, which include all Xiaomi models, you need to activate this profile. Mode switching is usually done by a combination of buttons, which is signaled by the LED indicator.
In Android mode, the indicator should flash blue, which indicates that the device is ready for search. If you see a red or green light, then the mode is active for iOS or PC, respectively, and pairing with the phone may not be correct or the buttons will not work correctly.
- 🔋 Charge the gamepad to a level of at least 50% for stable operation.
- 📱 Make sure that the Bluetooth module is enabled on Xiaomi smartphone.
- 🎮 Switch the controller to Android mode (blue indicator).
- ⚡ Use a short cable to charge quickly during the game.
⚠️ Warning: If the light flashes red, it signals a critically low battery charge. In this mode, the device may not be detected by the phone or permanently shut down.
The process of pairing via Bluetooth on Xiaomi
To start the connection, unlock the screen of your Xiaomi smartphone and go to the main settings menu. Find the Bluetooth section and activate the device search. Make sure that geolocation is enabled, as in modern versions of Android this requirement is necessary for the detection of peripherals.
Press and hold the on button on the Defender Crusher gamepad for 3-5 seconds until the LED flashes quickly.This means that the device has gone into visibility mode. The model name, often referred to as the Gamepad or Xbox Wireless Controller, should appear on the phone screen in the list of available devices.
Click on the device name in the list. The system may request a pairing confirmation or input PIN-In most cases, the code is not required, or the standard value is 0000. Once successfully connected, the indicator on the joystick will stop flashing and will burn with a steady light.
☑️ Connection check
Customize button emulation for games without gamepad support
Many mobile games, such as PUBG Mobile, Call of Duty Mobile or Genshin Impact, do not have native support for external controllers or block their use to maintain balance.
One popular solution is the ShootingPlus V3 or Mantis Gamepad Pro app. Once you install the software, you will need to calibrate the Defender Crusher gamepad buttons for a specific game, which allows you to assign each physical button a virtual click in a specific area of the screen.
The tuning process takes a few minutes, but it greatly improves the game's comfort: you can shoot, jump and control the camera with triggers and sticks, which gives you a tactical advantage over players using the sensor. It is important to keep the settings profile for each game separately.
Why do some games block the gamepad?
Table of compatibility and operating modes
Understanding the differences between modes of operation is critical to the proper functioning of the device. Defender Crusher is a multi-platform device, and its behavior changes depending on the chosen connection profile.
The table below shows the main characteristics of modes that will help you quickly navigate if the standard connection does not work or the buttons are pressed in the wrong place.
| Regime. | Indicator | Compatibility | Features |
|---|---|---|---|

If you have connected a gamepad to Xiaomi, but it is defined as an unknown device or the buttons are running chaoticly, most likely an incorrect profile is activated.Switch to Android mode according to the instructions for your specific device revision.
Solution: if the gamepad is not connected
Sometimes the pairing process can be interrupted or the phone just won't see the device. First, check the list of paired devices in the Bluetooth menu. If there's a Gamepad record with a connection error, delete it and try to find the device again.
A frequent problem on Xiaomi smartphones is an aggressive power saving system that can limit the operation of background processes or Bluetooth module. Go to the battery settings and make sure that there is no power limit for gaming applications and Bluetooth system services.
It’s also worth checking if the cache of Bluetooth services is full. Clearing the cache through the Settings menu → Apps → Show all apps → Bluetooth → Memory → Cleaning often helps to reset the communication protocol errors.
Use of wired connection via OTG
To minimize input lag in dynamic games, it is recommended to use a wired connection. Defender Crusher supports connection via USB cable, but to do this, your Xiaomi smartphone will need support for OTG technology.
Most modern models, including the Redmi Note series and Xiaomi Mi, support OTG by default.You'll need a USB Type-C to USB-A adapter (or micro-USB for older models). Just plug the gamepad cable into the adapter and then insert it into the phone's connector.
When wired, the device charges from a smartphone, which can quickly consume the phone’s battery, but provides maximum signal stability, in which the input delay is almost non-existent, which is critical for competitive games.
💡
When wired through OTG, the smartphone screen can go out faster due to high power consumption. Increase the screen timeout in the display settings.
💡
A wired connection via OTG provides minimal input latency, but requires an adapter and a charged smartphone battery.
Optimizing the gameplay on MIUI and HyperOS
Xiaomi’s shells have a built-in Game Turbo game mode that can conflict with or improve some of the gamepad’s features. Add your game to the Game Turbo app list to prioritize CPU resources.
In Game Turbo settings, you can disable the navigation buttons lock when playing, which is important if you use mappers, and it is also recommended to disable notifications and calls during the game session so that the incoming call does not interrupt the Bluetooth connection.
For advanced users, the option of increasing the sensitivity of the touchscreen is available, which in combination with the gamepad gives the most responsive control. Don’t forget to periodically update the firmware of the smartphone, as updates often contain patches for the Bluetooth stack.
⚠️ Note: When using wired connections through cheap adapters without shielding, interference and signal loss are possible. Use only certified cables with data transmission support.
