The screen doesn't respond to taps, the remote doesn't connect to devices, or the app doesn't start at all? The problem can lie in both software failures and hardware limitations of your Xiaomi.

In this article, we will look at all the possible causes of Mi Remote failure, from the banal lack of permissions to damage to the IR transmitter, how to diagnose a problem, what settings to check first, and when to contact the service center, and we have prepared a checklist for quick check-up and answers to frequent user questions.

If you want to use Xiaomi Redmi Note 12, POCO X5 Or another model suddenly lost the ability to control the TV or air conditioner — don't rush to blame the manufacturer. 80 percent of the time, the problem is solved in 5 minutes without special skills.

1. Checking the basic working conditions Mi Remote

Before digging deeper, make sure the minimum requirements for the app are met, and many users miss these points by spending time looking for complex solutions.

First, check if your Xiaomi model supports an infrared port (IR transmitter).Not all of the company’s smartphones are equipped with it, such as the Xiaomi 13 Lite or the Xiaomi X-ray. POCO M6 Pros may not have it. A full list of models with an IR port can be found on the official website in the specifications section of the device.

Second, make sure your phone is turning on the IR port in the settings.

1. Go to Settings. → Connected devices → Infrared port.
2. Activate the switch if it is switched off.
3. Check whether the port access is blocked by the power saving mode (more on this in the next section).

The third key is the compatibility of the managed device. Mi Remote works with most brands (Samsung, LG, Sony, Xiaomi), but some older models or rare Chinese devices may not be supported.Check the list of compatible brands in the app itself in the Add Device section.

2. Software failures: updates, cache, permissions

If the basics are met, but the Mi Remote still doesn't work, it's probably a software failure, and let's start with the simplest thing, which is to check the permissions of the application.

Go to Settings. → Annexes → Application management → Mi Remote and make sure it's on:

• 📱 Access to the camera (required for some scanning features)
• 📡 Access to location (sometimes required for geolocation functions)
• 🔋 Auto-run (so that the application does not close with the background optimizer)
• 🛡️ Ignoring battery optimization (critical for stable operation)

If the permissions are in order, the next step is to clean the cache and the application data, which helps in 60% of software failures.

1. Open the Settings. → Annexes → Mi remote.
2. Press Warehouse. → Clear the cache.
3. If it doesn’t work, choose Clear Data (Warning: This will delete all saved remotes!).

Then check the version of the app.The outdated version of Mi Remote may conflict with the latest updates. MIUI. Update the app via Google Play or App Gallery. If there are no updates, try reinstalling it completely.

Hardware problems: IR port and sensors

If the software methods don't work, the problem can be in the hardware, and most often the infrared transmitter itself fails, either because of physical damage or because of factory defects.

How to check the efficiency of the IR port?

1. Open the Camera app on another smartphone (like your iPhone or Xiaomi’s second one).
2. Point the camera at your Xiaomi’s IR port (usually located at the top of the case).
3. Start the Mi Remote and press any button (e.g., turn on the TV).
4. If the IR port is working, you'll see a purple flicker on the screen of the second phone, and if there's no flicker, the port is faulty.

Other signs of hardware problems:

• 🔦 The IR port is physically damaged (scratches, dents, traces of moisture).
• 📉 The Mi Remote does not detect the port in the settings.
• 🔄 The port is unstable (it is detected, then not).
• 💧 The phone was exposed to moisture or falls.

If the IR port is faulty, there are two options:

1. Contact the service center (if the phone is guaranteed).
2. Use alternative management methods (Wi-Fi/Bluetooth-The remotes, if the technology supports them).

Conflicts with MIUI and battery optimization

Operating system MIUI It's known for its aggressive optimization of the background of applications, and it's often the reason why the Mi Remote doesn't respond to commands or shuts down suddenly.

The first thing to do is to turn off battery optimization for the application:

1. Go to Settings → Battery and Performance → Battery Consumption Management.
2. Find Mi Remote in the list and select No Limits.
3. Also, turn off the Adaptive Battery in the same menu.

Second, check the background restrictions:

1. Go to Settings. → Annexes → Application management → Mi remote → Background restrictions.
2. Make sure there are no restrictions on work in the background.

The third thing is the energy saving mode. MIUI (Especially on budget models like Redmi. 10A or POCO M4) If you turn on the power saving mode, you can completely block the IR port. → Battery → Energy saving regime.

If the problem persists, try resetting your optimization settings:

1. Go to Settings → About Phone → MIUI version.
2. Click on the MIUI version several times to activate the developer mode.
3. Back to Settings → Additionally. → For developers.
4. Find the option Reset Battery Optimization Settings and activate it.

💡

After the update MIUI Mi Remote stopped working, try to roll back to the previous firmware version through Settings → The phone. → Updating the system → Three points. → Select the service pack. To do this, pre-download the old version. MIUI From the official Xiaomi website (Downloads section).

5. Problems with device compatibility

Even if your Xiaomi is equipped with an infrared port and the Mi Remote is stable, there may be problems with the compatibility of specific devices, for example, the application may not recognize rare models of air conditioners or old TVs.

How to check compatibility:

1. Open the Mi Remote and press Add the device.
2. Select a category (such as a TV).
3. Scroll through the list of brands – if your manufacturer is not, try to choose Universal.
4. If that doesn’t work, check if your technique supports remote learning (the Custom Remote function in Mi Remote).

Frequent compatibility issues:

If your device is not recognized, try alternative management apps:

• 📱 AnyMote (supports training teams)
• 🎛️ ZaZa Remote (extended codebase)
• 🔄 SURE Universal Remote (working on the Wi-Fi/Bluetooth)

💡

If your appliances support Wi-Fi or Bluetooth control (e.g., Xiaomi Mi smart TVs) TV or Gree U Crown air conditioners, use these protocols instead of IR. They are more stable and do not depend on the physical state of the IR port.

External disturbances and operating conditions

Infrared signal is sensitive to external conditions. If the Mi Remote is unstable (it reacts, then does not), check the following points:

Distance and angle of direction

• 📏 Maximum distance for the IR signal — 5-7 Meters (under ideal conditions).
• 🎯 Direct the phone directly to the receiver of the controlled device (usually located in the front).
• 🚫 Avoid obstacles: Glasses, mirrors, glossy surfaces can reflect or absorb the signal.

Sources of interference

• ☀️ Direct sunlight on the phone’s IR port or receiver.
• 💡 Fluorescent lamps or LED-flashlight.
• 📶 Working nearby wireless devices (routers 5 GHz, microwaves).

Status of the IR port

• 🧴 Port pollution (dust, grease, film glue residues) Clean it with a soft brush or compressed air.
• 💦 Moisture ingestion (even a small amount can cause corrosion of contacts).

If you suspect that interference is the problem, try operating the equipment in another room or in the dark (to rule out the effects of sunlight).

💡

To check the stability of the IR signal, use the application IR Tester (available on Google Play) shows the strength of the signal in real time and helps determine the optimal distance and angle.

7. When to contact the service center?

If you have tried all the methods, but Mi Remote still does not work, it may be a problem that requires professional intervention.

⚠️ Warning: If the phone has been in water (even for a short time), do not try to dry it with a hair dryer or rice. Corrosion of the contacts of the IR port can manifest itself in a few days, in this case, you need a complete dismantling and cleaning of the board in the service center.

Signs that you need the help of a specialist:

• 🔧 The IR port is physically damaged (cracks, chips, traces of oxidation).
• 📵 The Mi Remote app does not detect the port in the settings, although it is by specification.
• 🔄 The port is unstable (it appears, then disappears from the system).
• 💥 The phone has been hit or dropped.
• 🔋 After replacing the battery or screen, the IR port stopped working (possibly damaged plume).

The cost of repairing the IR port in service centers:

Before the service visit:

1. Make a backup copy of the data (in case of resetting).
2. Check if the warranty is maintained (if so, the repair may be free).
3. Check if the problem is software-based (try Mi Remote on another Xiaomi).

💡

If your Xiaomi is still under warranty, don't open it yourself! This will void warranty obligations. Contact the official Xiaomi service center - the list of addresses can be found on the website mi.com/ru/service.
