Modern Xiaomi smartphones come with a variety of useful modules, including the built-in infrared transmitter, which turns the gadget into a universal control panel, allowing you to interact with TVs, air conditioners and other household appliances without finding the original remotes. However, many users are faced with the fact that the feature does not work immediately after purchase or disappears from the interface after upgrading the system.
The correct operation of the infrared emitter requires not only the physical presence of the module in the housing, but also the correct software configuration. Often the problem lies in the lack of permissions for the system application or the wrong region in the device settings. In this article, we will discuss in detail all the steps of activation, configuration and diagnosis of possible failures.
Turning on an IR port is not just an application installation, but a comprehensive setup of communication between the hardware and the software MIUI or HyperOS. Understanding the principles of this module will help you avoid common mistakes and quickly manage home electronics.
Checking the presence of an IR module in the device
The first step before any manipulation of the settings should be to make sure that your smartphone is technically equipped with an infrared transmitter. Not all models in the budget and mid-range segment have this module, so it is important to check the specification of your device.
Visually, you can find the port by looking at the top of the phone in good light, and you will see a small circular hole, often surrounded by black or dark red glass, which can be hidden in a line with other sensors. If it is difficult to visually determine the presence of a module, you should consult the official specifications on the manufacturer's website or in the documentation attached to the box.
There are also software-based ways to check through system reports or iron diagnostic applications that show a list of available sensors. The absence of a Consumer Infrared or IR Blaster record in the hardware list means that software activation is impossible because the physical module is missing.
⚠️ Warning: Using third-party apps from the Play Market store that promise to emulate the IR port on phones without it makes no sense.These programs only work through Internet databases if the TV has a Smart TV Wi-Fi, but not a replacement for physical infrared emitter.
Below is a table of popular models and the presence of an IR port for quick check:
| Smartphone model | Availability of an IR port | Location. |
|---|---|---|
| Xiaomi Redmi Note 10/11/12 | There is. | Upper end |
| Poco X3/X4/X5/NFC | There is. | Upper end |
| Xiaomi Mi 11/12/13 | No (in some versions) | Absent. |
| Redmi 9/10/11/12 (basic) | There is. | Upper end |
| Poco M3/M4/M5 | There is. | Upper end |
If you have a module in your model but it doesn't work, then we'll move on to the software part, and the lack of a physical port makes further instructions useless for your particular device.
Installation and initial configuration of the Mi Remote application
The main tool for managing equipment is the system application Mi Remote (in some regions called Mi Remote), which is often preinstalled in global firmware versions, but can be hidden in the Tools or Services folder. If you do not find it on your desktop, check the folder with system utilities or search the phone settings.
If you delete the application or it is not in the stock build, you need to download the official version. It is important to use the original application from Xiaomi, as third-party counterparts may not have access to the system IR module without root rights. Once installed, run the program and provide all the requested permissions, especially access to location and Bluetooth, if they are required for pairing.
When you first start up, the system will ask you to select the type of device you want to control. Select a category, for example, "TV", and start the process of adding a new remote, and the application will ask you to choose the manufacturer of your equipment from the list or find it through a search.
☑️ Primary settings Mi Remote
The key is to test the buttons, and you'll see a few buttons on the screen, and the app will ask if your appliances are responding to them, press the buttons consistently, and answer questions honestly so that the system can calibrate the signal frequency to your particular TV or air conditioner.
The Impact of Region and System Settings
One of the most common reasons why the IR port is not turned on or the remote application is not working is the wrong region in the smartphone settings. The functionality of some MIUI and HyperOS system applications depends on the geolocation specified in Settings → Additional settings → Region.
If you have selected a region "Russia" or some European countries, the application may work correctly, but in rare cases the database of remotes may be limited.
You also need to check the permissions for the Mi Remote application itself. Go to Settings → Apps → All Apps → Mi Remote → Permissions. Make sure you allow access to run in the background and, if any, access to the IR port (although this is usually the system resolution).
💡
If after changing the region, the remote has earned, but voice input has disappeared or widgets have changed, try clearing the cache of the Service and Feedback application before returning the region.
Also worth paying attention to is the power saving mode: Aggressive charge saving settings can block the IR module from working as a background process, add the remote app to the exclusion list, or set the "No Limits" mode for it to work.
⚠️ Warning: Changing the region to China could lead to ads in system apps or a change in the list of recommended news in the browser. MIUI.
Step-by-step: Adding a new device
The process of adding the remote is standardized, but requires careful selection of codes. After you start the application, press the + button in the corner of the screen. The system will suggest choosing a category of device: TV, console, air conditioner, projector or fan.
Choose your manufacturer. If your brand is not listed, search by name or select the Search option to automatically brute-force your codes. In manual mode, you will be offered multiple remote options for the same brand.
Point the phone to the device and press the Test button on the screen. If the equipment reacts (for example, changes volume or turns off), press Yes. If there is no reaction, No, and the system will suggest the next code variant, which can take several minutes, but guarantees accurate adjustment.
After successfully testing all the basic features (on, volume, menu), give the name of the remote, for example, "TV in the living room", which is especially convenient if you have multiple remotes for different rooms or devices.
Diagnostics and solution of signal transmission problems
If the remote is configured but the signal is not passing, the problem may be in the distance or angle of the tilt.Infrared port requires line of sight and operates at a distance of up to 7-10 meters.
A common cause of failure is a protective glass or cover covering the IR emitter. Some thick cases with high sides can block the beam, making control impossible. Remove the case and check the remote again.
It’s also worth checking if the phone is not enabled with Do Not Disturb mode or specific profiles that may limit the operation of system services.Rebooting the smartphone often helps to reset the temporary errors of the IR driver.
How to check the operation of the IR port through the camera?
In rare cases, resetting the Mi Remote app to factory settings helps. Go to Settings → Applications → Mi Remote → Memory → Clean. This will remove all saved remotes, but can fix the software glitch.
Use of third-party applications and alternatives
If the standard Mi Remote app seems uncomfortable or doesn’t support some exotic device, you can use third-party solutions from the Google Play store. Apps like ZaZa Remote or Lean Remote often have more extensive codebases and flexible settings.
When installing third-party software, be sure to give it access to the IR port. Unlike a system application, third-party programs need to explicitly give permission in the MIUI security menu. Without this, they will only work in Wi-Fi (for Smart TV), ignoring the IR module.
However, it is worth remembering that third-party applications can consume more battery resources or contain advertising. Xiaomi’s system solution is optimized best and integrated into the shell, allowing, for example, to display the remote on the lock screen or use widgets.
💡
Third-party apps are a great addition if the desktop didn’t find the code for your old tech, but for everyday use, the native app is more stable.
For advanced users, there is the possibility of creating macros where a single button triggers a chain of action, but this requires a deeper dive into the system automation settings.
