How to find out if there is an IR port on the Xiaomi Redmi smartphone: a complete guide with verification

The infrared port (IR) in Xiaomi Redmi smartphones is a convenient feature that allows you to control household appliances (TVs, air conditioners, music centers) directly from your phone, replacing many remotes. However, not all Redmi models are equipped with this module, and in some regions the manufacturer can exclude it from the configuration. How can you determine exactly whether there is an infrared port on your device without disassembling the case?

In this article, we will discuss 5 reliable ways to check, from visual inspection to software diagnostics, and also tell you which Xiaomi Redmi models exactly support IR control. You will learn exactly where the port is located, how to activate it in the settings and what to do if the phone does not recognize the technique.

If you are planning to buy Redmi specifically for control equipment or have already encountered problems when using an IR remote, this guide will help you avoid errors and save time.

1. Visual inspection: where to look for an IR port on Xiaomi Redmi

The easiest way to do this is to look at the top of your smartphone, and the IR port in Xiaomi is usually located on the top end, next to a headphone jack (if any) or speaker, and it looks like a small dark window (sometimes reddish) of 2-3 mm, covered with transparent plastic.

Here’s how to distinguish the IR port from other elements:

  • πŸ”΄ IR port: a round or oval opening with a matte surface, often near a front camera or light sensor.
  • πŸ“· Front camera: larger in size, with a lens, sometimes with a metal rim.
  • 🎀 Microphone: small hole, but without transparent coating.
  • πŸ’‘ Light sensor: an almost invisible hole, often hidden under the glass of the screen.

On some Redmi models (such as the Redmi Note 10 Pro or Redmi K40), the IR port can be hidden under a black speaker grid - it can only be seen in bright light at an angle. If you're not sure, compare your phone to the official specs photos (more on this below).

⚠️ Warning: On devices with a factory film or case, the IR port may be closed. Remove the protection before inspection - sometimes the transparent film completely blocks the signal.

πŸ“Š You’ve already tried to find an IR port on your Xiaomi Redmi?
Yes, I did.
Yeah, but I didn't.
No, I didn't.
I don't know what that is.

2.Model check: Xiaomi Redmi list with IR port

Not all Xiaomi Redmi smartphones have an infrared port, such as the budget models (Redmi 9A, Redmi 10A) and some versions for the global market (Redmi Note 11 for Europe) often lack this module.

SeriesModels with IR portModels without an IR portNotes
Redmi Note 12Note 12 Pro+, Note 12 Pro Speed, Note 12 TurboNote 12 (global version), Note 12SIn China, the IC is in all modifications.
Redmi Note 11Note 11 Pro+, Note 11T ProNote 11 (Europe), Note 11SIR is not available in India versions
Redmi 10Redmi 10 (China), Redmi 10X 5GRedmi 10 (global), Redmi 10ABoth versions were sold in Russia.

Redmi 9Redmi 9 (China), Redmi 9T NFCRedmi 9A, Redmi 9CIn Europe, IR is only in 9T.

If your model is not in the table, check the specifications on the official Xiaomi website (Specifics section) or use services like GSMArena. Pay attention to the regional modification: for example, the Redmi Note 11 Pro+ 5G for China has an IR, and for Europe – not.

πŸ’‘

To know exactly the model of your Redmi, go to Settings β†’ About Phone β†’ Model. If the name has the letters Global or EEA, this is the version for Europe, where IR is often absent.

3. Software verification through MIUI settings

If the visual inspection fails, check for the IR port through system settings. MIUI has a built-in app for control that only activates when a physical module is present.

Follow the instructions:

  1. Open the settings (cog icon).
  2. Go to Connections and Sharing (or Communication and Sharing in new versions of MIUI).
  3. Scroll down and find Infrared Port or Smart Home.
  4. If there is a point, your smartphone supports IR. If not, the module is physically not.

On some firmware (e.g. MIUI 14), the path may be different: Settings β†’ Special Features β†’ Physical buttons β†’ Infrared port.

Open Settings|Find the section "Connections and Sharing"|Check for the item β€œInfrared port"|If there is no point, there is no IR-->

If there is a Smart Home section in the settings, but there is no separate item for IR, try adding the device manually:

  1. Open Mi Home (the app must be pre-installed).
  2. Click Add Device (+).
  3. Select a category, such as a TV.
  4. If you request to use an IR port, the module is present.

⚠️ Note: Custom firmware (such as LineageOS or Pixel Experience) has built-in settings MIUI In this case, use third-party applications to check (see the next section).

4.Use of third-party diagnostic applications

If your system settings don't give you a definitive answer, install specialized hardware testing tools to scan for an IR module and test its performance.

Top.-3 Android:

  • πŸ“± IR Tester (a simple IR port test with signal visualization).
  • πŸ” Phone Tester (checks all sensors, including IR).
  • πŸŽ›οΈ Remote Control Tester (tests sending IR commands).

How to check with the IR Tester:

  1. Install the app from Google Play.
  2. Run it and press Test IR.
  3. Direct the IR port to another smartphone’s camera (or turn on the front camera on your phone).
  4. If you press the Send button on the camera screen appears purple flicker - IR works.

If the application produces an error No IR hardware found, it means that there is no physical module. Note: some applications may show a false positive result on virtual IR devices (for example, via Bluetooth), but this method is not suitable for controlling traditional equipment.

Why can’t IC work even if there is a port?
Causes of malfunction of the IR port: 1. Module contamination - dust or fat block the signal. 2. Damage after a fall - microcracks on the board. 3. Disconnection in the firmware - some custom ROM remove support for IR. 4. Conflict with the case - dense bumpers can block the port. 5. Hardware defect - defect in production (rarely, but occurs).

5. Check through the Engineering Menu (for advanced)

If you’re confident in your skills, you can look at the smartphone’s engineering menu, which displays all the hardware components, a method that works for Xiaomi Redmi on a pure MIUI (no root).

Instructions:

  1. Open the Phone app.
  2. Enter the combination: ##4636###.
  3. In the menu that opens, select Phone Information.
  4. Scroll down to the Sensors section.
  5. Find the IR Sensor or Infared Port string.

If the line is missing or Not available is nearby, there is no IR port. On some devices, you can use the MTK Engineering Mode app instead of the engineering menu (for smartphones on MediaTek processors):

MTK Engineering Mode β†’ Hardware Testing β†’ IR Test

⚠️ Warning: Do not change other options in the engineering menu - this can cause malfunctions in the phone.If you are not sure about your actions, use alternative methods of checking.

πŸ’‘

The engineering menu is the most accurate way to check, but it takes care, and if you don't find the IR section, it's guaranteed to mean no module.

6. Alternative methods of control of equipment without IR

If your Xiaomi Redmi is not equipped with an infrared port, it does not mean that you can not control the equipment from your smartphone.

  • πŸ“Ά Wi-Fi remotes: Many modern TVs (Samsung, LG, Sony) supports management over the local area network. Use official applications manufacturers.
  • πŸ”΅ Bluetooth remotes: Some air conditioners (Midea, Gree) have Bluetooth modules. IR Remote.
  • 🌐 Smart outlets and hubs: Devices like Xiaomi Mi Smart Socket or Aqara Hub allow you to control equipment through the cloud.
  • πŸ“± Universal IR Remotes: Buy an external IR blaster (e.g. BroadLink) RM4 Pro, which connects over Wi-Fi and works with any smartphone.

For Xiaomi owners, the most convenient option is the Mi Home ecosystem. Even without an infrared port, you can connect smart lamps (Yeelight), robot vacuum cleaners (Mi Robot Vacuum) or air conditioners with a Wi-Fi module. The main thing is to make sure that your equipment is compatible with Mi Home (the list of supported devices is available on the Xiaomi website).

If you want to use IR, consider buying a smartphone with confirmed support, including the Redmi Note 12 Pro+ (China), POCO X5 Pro or Redmi K60E.

FAQ: Frequent questions about the IR port in Xiaomi Redmi

My Redmi Note 10 Pro doesn't run air conditioning. Does that mean it doesn't have an IR port?
First, check: Is there an Infrared port in Settings β†’ Connections. Does your air conditioning model support in the Mi Remote app (update the database in the application settings). Is the port closed with a cover or film. If the port is there, but does not work, try resetting the Mi Remote app or reinstalling it.
Can I install an IR port in a smartphone if it is not available?
No, it's impossible. An IR port is a hardware module soldered into a motherboard, and it can't be added software or externally (except for individual IR blasters that connect over USB/Bluetooth).
Why is my Redmi’s IR port listed but not?
This is typical for Xiaomi: You bought a regional version (for example, for Europe), where the IR is removed, the manufacturer changed the configuration without updating the specifications (found in budget models), you see the characteristics of another version (for example, Redmi Note 11 Pro + 5G for China vs. global version). Always check the equipment by serial number or buy the device in official Xiaomi stores.
How to check the IR port on Redmi with custom firmware?
On unofficial firmware (for example, LineageOS) system settings MIUI Use: Sensor testing applications (Phone Tester) Terminal with command: cat /proc/cpuinfo | grep Hardware (if there is a mention in the conclusion) ir_remote, Connecting an external IR blaster to check compatibility.
Can an IR port break down from frequent use?
An IR port is a passive module with no moving parts, so it doesn't wear out. However, it can fail for the following reasons: Mechanical damage (fall, impact), fluid getting inside the case, short circuit on the board (rarely). If the port stops working, try cleaning it with a soft brush or resetting the phone. If that doesn't work, contact the service center.
