The headphone icon, which persistently appears in the status bar of Xiaomi, even when you have long disabled them, is one of the most common problems among owners of smartphones Redmi, POCO and Mi. This bug is not only annoying visually, but can also signal more serious problems: from a malfunction of the audio jack to software errors in the firmware.
In most cases, the reason is the system's incorrect identification of the connected device. For example, if you used wired headphones with a non-standard connector or a Bluetooth headset with a poor connection, MIUI can "hang" in accessory recognition mode. Less often, the problem lies in the physical damage to the socket 3.5 mm or contacts inside the device. In this article, we will discuss all possible ways to eliminate the icon from simple to radical, including hidden developer settings and hardware diagnostics.
Important: If the icon appeared after a phone drop or moisture, first check the operability of the audio jack, in such cases, software methods may not help, and will require repairs.
1.Rebooting the smartphone is the first step
Start with the simplest: reboot the device. In 30 percent of cases, the headphone icon disappears after a normal reboot, as the system resets temporary data about the connected devices.
How to properly reboot Xiaomi:
- 🔄 Press the power button for 2-3 seconds.
- 📱 In the menu that appears, select “Reboot” (not “Switch off!»).
- ⏳ Wait for full shutdown and automatic switching on (usually takes 30-60 seconds).
If you have the badge left after the reboot, try a hard reset, press the power button and increase the volume simultaneously for 10-15 seconds until the screen goes out, which helps when the system is "hang" at the core level.
💡
If the icon disappears after the reboot, but returns when you connect the headphones, the problem is with the accessory itself. Try using another headset.
2. Cleaning the cache of the “Phone” and “Settings” application
The headphone icon is managed by system services that are stored in the cache. If the cache is corrupted, MIUI may mistakenly "think" that the headphones are connected. Clearing the cache for key applications often solves the problem.
Instructions:
- Open Settings → Applications → Application Management.
- In the search bar, enter “Phone” (calling app).
- Select "Storage» → «Clear the cache».
- Repeat the steps for the Settings app.
After cleaning, restart your smartphone. If the method didn’t work, try clearing the cache for all system applications through the recovery mode (discussed below).
What is cache and why should it be cleaned?
3. Resetting audio and Bluetooth settings
If the icon appears when you connect a Bluetooth headset, the problem may be a conflict of profiles of the device, resetting the audio settings and Bluetooth will return the parameters to factory values.
How to reset the sound settings:
- 🔊 Go to Settings. → Sound and vibration.
- 🎧 Click on three dots in the upper right corner → «Reset the settings».
- 🔄 Confirm the action and restart the phone.
For Bluetooth reset:
- 📶 Open the Settings. → Connections and sharing → Bluetooth.
- 🔄 Press three points. → «Clear the data" (this will delete all paired devices!).
- 🔗 Reconnect the headset.
Attention! After the Bluetooth reset, all the stored devices (earphones, speakers, fitness bracelets) will be removed. Write down their names in advance so you can quickly reconnect them.

4. Enabling Developer Mode and Debugging
In the hidden MIUI settings, there are settings that allow you to manually control the recognition of connected devices, and you need to activate the developer mode.
How to turn on the developer mode:
- 📱 Go to Settings. → The phone.
- 🔧 Click 7 times in a row on the item "Version" MIUI» (A notification will appear saying, “You have become a developer!»).
- 🔙 Return to the main settings menu and open a new section for developers».
Now, do the following:
- 🔍 Find the option "Debugging by" USB» and turn it on.
- 🎧 Scroll down to the Net Absolute Volume block (this will reset volume settings).
- 🔄 In the Login section, find “Disable the Check for Headphone Connection” (if any) and activate it.
Critical information: On some models (e.g. Redmi Note 10 Pro), the option to turn off headphone connection check is hidden. To see it, first turn on the "Show settings for power users" in the developer menu.
5. Hardware diagnostics: check of connector and contacts
If the software methods didn't work, the problem could be physical damage to the audio jack or the contacts on the board.
Steps for diagnosis:
- Visual inspection: Take a flashlight and inspect the 3.5mm socket for dirt, oxidation, or bent contacts.
- Test with other headphones: connect the headset knowingly working. If the icon does not appear, the problem is in your headphones.
- Multimeter check: If you have a tester, measure the resistance between the connector contacts (you need to disassemble the phone).
Typical signs of hardware failure:
| Symptoms. | Probable cause | Decision |
|---|---|---|
| The sign appears at the slightest touch of the connector | Oxidation or short-circuiting of contacts | Cleaning with alcohol or replacing the connector |
| The sound is distorted or lost in one headphone | The cable or connector contacts are damaged | Replacement of headphones or connector |
| The badge does not disappear even after flashing. | Problem at the motherboard level | Diagnostics at the service center |
⚠️ Attention! If you don't have experience in electronics repair, don't try to clean or solder the contacts yourself. Wrong actions can short circuit and cause the phone to fail completely.
Extreme measures: reset to factory settings
If none of these methods work, you'll have to reset your phone completely, and that will delete all the data from the phone, but it will return the system to its original state by eliminating the software errors.
How to reset:
- 📱 Go to Settings. → The phone. → Resetting settings.
- 🔄 Select Reset All Settings (not to be confused with Reset Network Settings!»).
- 🔐 Enter the password from the Mi Account (if tied).

- 📱 Extract. SIM-card and memory card (if any).
If after resetting the headphone icon is still displayed - the problem is 100% hardware, and the phone requires repair in the service center.
💡
Factory reset is the latest software method, and if it doesn't work, don't waste time on other instructions: the malfunction is hardware-related, not software-related.
