Smartphones are no longer just call devices, becoming universal remotes for all home appliances. Owners of Xiaomi, Redmi and POCO devices often wonder about the presence of an infrared module, since it allows you to control TVs, air conditioners and audio systems without finding the original remotes.
Checking for an IR port doesn’t always require a deep dive into technical specifications or disassembling a gadget. There are several software and visual techniques that allow you to quickly determine whether your device is equipped with a signal transmitter. In this article, we will look at all the verification methods available, from simple inspection of the case to the use of specialized utilities.
Having this module greatly expands the functionality of the device, turning it into a smart home control center. If you plan to use the phone as a universal remote, it is important to make sure that your model supports this technology in advance, since manufacturers often exclude the IR module from budget lines.
Visual inspection of the device body
The simplest and most reliable way to make a primary diagnosis is to look closely at the top of a smartphone. An infrared transmitter is a small, circular hole, often surrounded by black or dark red glass, that is visually different from noise reduction microphones or proximity sensors.
Note the location of the elements: the IR port is usually next to the headphone jack (if any) or microphone. On many Xiaomi models, this hole has a characteristic shine when light hits, which helps distinguish it from the usual plastic coating of the case.
It's worth considering that in some modern designs, manufacturers disguise the sensor as the color of the case, making it less noticeable. If you don't see a clear hole on the upper end, this does not guarantee its absence, but significantly reduces the likelihood of having a full-fledged hardware IR module.
⚠️ Warning: Do not attempt to clean the IR port hole with sharp objects or alcohol, as this may damage the sensitive sensor or protective glass, which will lead to incorrect operation of the remote control.
Checking through the Mi Remote system application
The main tool for working with infrared radiation in the shell of MIUI and HyperOS is the pre-installed application Mi Remote (or Remote), the presence of this application in the system is a strong indicator that the hardware for transmitting infrared signals is present in the device.
Start the program and try adding a new device, and if you're asked to select a type of equipment (TV, air conditioner, set-top box) and a brand, and then the phone starts sending test signals, then the infrared port is active and functional.
In some regions or firmware, the app may be hidden or removed, in which case it can be found in the Tools folder or downloaded from the GetApps store. If a message appears when you launch about a lack of support or the application immediately closes, chances are your smartphone does not have the necessary module.
It is important to note that the application is not only hardware-dependent, but also permission settings are correct. Make sure that Mi Remote has access to the necessary system functions, although this usually happens automatically when you first start.
☑️ Diagnosis through Mi Remote
Analysis of the technical characteristics of the model
The most accurate method that doesn’t require manipulation of your phone is to look at the official specification of your model, and manufacturers always indicate the presence or absence of InfraRed module in the “Communications” or “Sensors” section of the site or in the box.
You can also use specialized applications from Google Play, such as AIDA64 or Device Info HW. These utilities read data directly from the system and give a full list of available hardware, including Consumer IR.
When searching for information on the Internet, use the exact model name listed in the Settings → About Phone section. Often, different modifications of the same smartphone (for example, the global and Chinese versions) may differ in the set of sensors.
Why do you write Consumer IR in the specifications?
Comparison of popular Xiaomi and Redmi series
Understanding company policies helps you quickly navigate the availability of a feature, and historically, flagship series and many mid-range models have been equipped with an IR port, whereas ultra-budget ones are less common.
Below is a table showing the module in different product lines, and note that the data may vary depending on the year of release of a particular model.
| Series of devices | Availability of an IR port | Typical location | Note |
|---|---|---|---|
| Xiaomi Flagman (Mi 11, 12, 13, 14) | There is. | Upper end | Standard for flagships |
| Redmi Note (series 8-13) | There is. | Upper end | Popular feature in the middle segment |
| POCO (F and X series) | There is. | Upper end | Often inherited from Redmi |
| Redmi A/C Series | No. | - | Budget segment without module |
The table shows that the probability of having a port is high in the devices of the Redmi Note and POCO series. However, if you are the owner of a device of the Redmi A series or very old models of the Mi line (before the Mi 4), the probability of not having a feature tends to maximum.
💡
The presence of an infrared port in Xiaomi smartphones depends not only on the price, but also on the positioning of the series: in gaming and multimedia lines it is almost always there.
Using third-party applications for testing
If the built-in tools don't give a clear answer, you can use third-party software. There are many applications on the Google Play store, such as IR Test or Peel Remote, that can determine the presence of Consumer IR Hardware.
Once you install this application, run a scan. The program will try to find the IR transmitter drivers in the system. If the driver is found, the application will confirm the presence of hardware support and offer to conduct a test signal sending.
Be careful when choosing software: many free apps are full of ads. It is recommended to choose programs with high ratings and a large number of reviews to avoid installing malware on your Android smartphone.
⚠️ Note: Third-party remote apps may not work properly with some TV models, as they do not have access to updated codebases, which are in the official Mi Remote.
Possible problems and solutions
Even with a port, users may find themselves in a situation where the remote is not working, and often the problem is not the hardware, but a software failure or incorrect configuration, and the first thing to do is check if the hole is covered with a cover or protective film.
Sometimes it helps to clean the Remote app cache through the Settings menu → Apps → All Apps → Remote → Storage → Clean. This resets temporary files that could have caused the conflict.
If none of the methods worked, and the specification says there's a port, the plume or the module itself may have been damaged, and then you'll need to be diagnosed at a service center, especially if the phone has been hit or moisture.
💡
When buying a new smartphone case, make sure it has a cutout under the top end, otherwise you will not be able to use the IR port to control the equipment.
