How to turn on the IR port on Xiaomi Redmi 10: the complete guide

Modern smartphones, including the popular Xiaomi Redmi 10, are increasingly equipped with a built-in infrared emitter that turns the gadget into a universal remote control, which allows you to forget about dozens of remotes for the TV, air conditioner, consoles and audio system, combining all control in one application.

In fact, Redmi and Xiaomi smartphones don’t have a physical button or tumbler in their system settings that turns on or off an IR port, like Bluetooth or NFC. The infrared emitter is on demand: it activates automatically the moment you launch the Mi Remote system application (Mi Remote) and select the device to control. If the remote doesn’t respond, the problem lies not in the disabled port, but in the application settings, calibration or hardware compatibility of the model.

In this article, we will discuss in detail how to configure the control of equipment on Xiaomi Redmi 10, what hidden features are available in the engineering menu and what to do if the standard remote does not see your equipment, you will learn how to check the performance of the IR sensor with the camera and how to avoid typical errors in the initial configuration.

Checking the presence of an IR emitter in the Redmi 10 model

The first step before setting up should always be to verify the presence of a hardware module in your particular device, the fact that the line of Redmi is heterogeneous: some models are equipped with an IR port, while others do not have it for the sake of cost. In the case of Xiaomi Redmi 10, the situation is as follows: the global version (Global Version) often does not have an integrated IR emitter, while the Chinese version (CN Version) or versions for some markets in Asia may be equipped with it.

You can visually determine the port by looking at the top of your smartphone. The IR emitter is a small black glass, often located next to a noise reduction microphone or speaker. If you only see a SIM tray and a microphone on the end, but there is no characteristic dark window, then your Redmi 10 probably does not have this function hardware, in which case software activation will be impossible.

Also worth checking the specifications in the device menu. Go to Settings → About Phone → All settings and carefully review the list of supported technologies. Although it rarely says "IR Blaster" directly, the presence of the Mi Remote application in the Tools folder is an indirect sign of the hardware part. If the application is not in the stock firmware, installing it from third-party sources will not add a physical emitter.

⚠️ Note: Installing third-party Universal Remote apps from Play Market will not create an IR port if it is not physically available.

For accurate assurance, you can use the technical specifications on the official website or device box. Look for the Infrared or IR marking in the list of communication modules. If the specifications only indicate NFC (which is also often not available in Redmi 10), Bluetooth and Wi-Fi, but there is no mention of infrared, then the module is missing.

Set up the Mi Remote app for managing machinery

If you are convinced that your Xiaomi Redmi 10 is equipped with an IR port, the next step is to properly configure the system application. In the shell of MIUI or HyperOS, Mi Remote (in Russian localization - "Mi Remote"), it is in the standard folder "Tools". When you first start, the application will request permission to use the IR port and access to geolocation (for selecting remotes by region), which must be confirmed.

The process of adding a new device is intuitive, but it requires careful consideration when choosing a model. Press the + button in the application interface, then select the type of equipment: TV, air conditioner, projector, Mi Box console or camera. Then a list of brands will appear. Find a manufacturer of your equipment, for example, Samsung, LG or Sony. If the brand is not on the list, you can search by name.

The key step is to test the codes. The app will offer multiple remotes for the same TV model, and you'll need to press the On/Off or Volume button on your smartphone screen and confirm if the technology is responding. The signal encoding can vary even for one-year devices, so sometimes you have to go through 3-4 options before you find a working one.

Once you've successfully selected the code, remember to give the remote a clear name, such as "Living room TV" or "Bedroom Air Conditioning," which allows you to quickly switch between devices if you add multiple remotes to the app, and you can change the order of the buttons in each remote setting or add macros for quick action.

IR port calibration and signal testing

Sometimes the remote is configured but not stable: the technology only reacts from close range or at a certain angle. In this case, you may need to calibrate or simply check the health of the emitter. Xiaomi smartphones do not have a separate calibration menu for the user, but there is an effective method of diagnosis using the camera of another smartphone.

The arrays of modern cameras are sensitive to infrared radiation that the human eye cannot see. To check if the infrared port on Redmi 10 is working, run the Mi Remote app and select any remote you add. Point the top of your smartphone (where the emitter is) into the lens of another phone's camera. Press any button on the remote screen.

If the IR port is functional and active, you'll see a bright purple or white flash on the camera screen in the emitter area. If there's no flash, try changing the angle of inclination or distance. The lack of glow when you press the buttons may indicate a software failure or hardware failure of the module.

You can use the engineering menu for a deeper diagnosis, although access to it is limited in new firmware versions. Try entering the code ##6484## in the phone app. If the CIT (Customer Interface Test) menu opens, look for an IR or Infrared test in the list, running this test will make the port emit a signal continuously, which will make it easier for the camera to check.

Use of alternative applications and codes

The Mi Remote app has a huge base, but it doesn’t always contain codes for rare or old appliances, and in these cases, users turn to alternative solutions from the Google Play store. Apps like Peel Smart Remote, SURE Universal Remote or AnyMote can have more flexible settings and codebases that are not available in Xiaomi’s firmware.

When installing third-party software, make sure it requests and gets permission to use the IR port. The principle of operation remains the same: brand selection and button testing. The advantage of third-party applications is often the ability to manually enter the signal frequency or create complex macros, for example, the serial switching on of the TV and receiver with a single button.

In addition, the interface of such programs can be overloaded, which is not always convenient when switching channels quickly. Use them only if the regular Mi Remote does not cope with your technique.

💡

Tip: If the remote is working but with a delay, try reducing animation time in the application settings or clearing the Mi Remote app cache in the Applications section.

Typical problems and ways to fix them

Even with a serviceable IR port, Xiaomi Redmi 10 users may face a number of problems, one of the most common is that the remote stops working after a system update, which is because new versions of MIUI can change drivers or permissions for system applications, in which case cleaning the Mi Remote application data through the settings menu helps.

Another common situation is dead zones, and the IR signal is cone-propagated, and if you hold the phone at too sharp an angle, the signal will not reach the receiver, and the signal can be blocked by the case if it has high sides or is made of dense opaque material that covers the upper end.

If the TV or air conditioner doesn't respond to any code at all, a non-standard frequency of signal modulation may be used. In rare cases, a full reset of network and Bluetooth settings helps, since the radio modules in the smartphone work together. Try resetting the network settings in the Settings menu → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.

⚠️ Attention: When using an IR port in bright sunny weather, the range may decrease. The infrared radiation of the sun creates noise that silences the remote signal.

Also worth mentioning is the problem with phantom taps: If the phone is in your pocket or on a table with a screen up, a random touch can send a signal and turn on the TV. To avoid this, you can turn off vibration when you press it (so you don’t want to touch the screen) or simply lock the screen when the remote is not in use.

💡

The main reason for the broken remote on Redmi 10 is the absence of a physical IR module in the global version of the smartphone, not a software failure.
