Xiaomi smartphone owners often face a situation where the device "thinks" that it has headphones connected, when in fact the socket is free.The lock screen shows the headphone icon, and the sound is played only through an external speaker with distortions or does not go at all. This is a common software glitch in the MIUI or HyperOS shell that is easy to fix.
This behavior could be caused by a dust plug, a software glitch, or a break in the terminal, and the system mistakenly reads the signal in the audio track as if it were an external device, and in most cases, you don't have to carry the phone to the service center, because you can solve the problem yourself in a few minutes.
In this article, we will discuss all the methods of eliminating the headset icon in detail. We will look at both software resets and physical cleaning, as well as touching on rare cases of hardware malfunctions. Xiaomi Redmi and Poco have a similar configuration structure, so the instruction will be suitable for most models of the brand.
Quick reboot and reset sound settings
The first and easiest step that users often ignore is to completely reboot the system, and restarting it allows you to clear a temporary cache that might have stuck the audio device's connection signal, and if you haven't turned your phone off completely in a long time, but only locked the screen, that could be the reason.
But sometimes a simple reboot is not enough, because there are advanced settings in the audio settings that can conflict, and you need to check if the mono-sound mode is activated or if the balance is not biased one way, which is sometimes interpreted by the system as working with a headset.
βοΈ Diagnostics of the sound module
Try to force the audio diagnostics to run, too, so you can run a speaker test on the engineering menu or through the Services app, and if the test shows an error or silence, the problem goes deeper than just a software bug on the interface, and then you might need to reset the settings.
β οΈ Before performing a full reset, be sure to save all important data to a cloud server or computer, as the phoneβs memory will be completely cleared.
Physical cleaning of the headphone jack
The most common reason for the earphone icon is the banal dust, pile or oxidation of contacts inside the 3.5 mm connector. The mechanical end inside the socket could stick due to the entry of small debris. The system sees the closure of contacts and thinks that the plug is inserted.
To clean, you'll need a dry toothbrush, compressed air, or cotton swab slightly soaked in alcohol (but not water!). Walk gently through the inside of the connector to try to sweep the dust out. Compressed air helps blow contaminants out of the channel where the brush is missing.
There's a folk method that helps you stir up a sticky tip: Take a headphone plug (preferably an old one that's not pathetic) and insert it into the connector, then quickly remove it. Repeat this procedure 10-15 times. Mechanical action often returns the spring mechanism to its original position.
What can't you clean the connector?
If you've cleaned it, but it's still quiet, maybe there's moisture inside. Put your phone on a dry surface in a warm place for a few hours. Silicagel will help you pull the extra moisture out of the speaker and connector faster.
Use of switching applications
If physical cleaning doesn't work, and rebooting doesn't work, Google Play Store utilities will come to the rescue, and these apps can programmatically switch audio output by ignoring the sensor signal in the connector, and they force the sound to the speaker.
One of the most popular solutions is the Lesser AudioSwitch app, which allows you to manually select the source of the output: speaker, headphones or Bluetooth. Once you install it, you can simply switch the slider to Speaker, and the headphone icon will stop interfering.
- π§ Lesser AudioSwitch β a powerful tool with manual control of sound routing.
- π Sound Assistant β allows you to fine-tune the behavior of audio in different scenarios.
- βοΈ Disable Headphone - a specialized utility specifically for disabling the headset mode.
It's important to understand that these apps don't repair the phone, they just get around the problem, they're a temporary solution if you don't want to disassemble the device, but they consume minimal resources and have little impact on autonomy.

If you use a Bluetooth headset all the time, try turning off the Audio option for all devices in Bluetooth settings to check if the Bluetooth module conflicts with the 3.5mm connector.
Resetting settings through the engineering menu
Xiaomi smartphones have a hidden CIT engineering menu designed to test components, which allows you to check the status of the audio module and sometimes reset it, and uses a special code in the Phone app to enter the menu.
Dial ##6484##. The test menu will open. Find the item associated with the audio (usually called "Receiver", "Speaker" or "Headset"). Run the test. If the test is successful but the icon is hanging, try switching between modes several times during the test.
| Parameter | Meaning/Action | Description |
|---|---|---|
| Entry code. | ##6484## | The main code for the Xiaomi CIT menu |
| Alternative code | ##4636## | Phone Information Menu (rarely helps with sound) |
| Section | Audio / Speaker | Audio track section |
| The result | Pass / Fail | Indicates status of the hardware component |
Sometimes it helps to clean the cache through ADB (Android Debug Bridge), but it requires a computer connection.Adb shell am broadcast command -a android.intent.action.HEADSET_PLUG -n com.android.systemui/.headset.HeadsetBroadcastReceiver It can emulate disabling headphones, but it doesnβt work on all Android versions.

An engineering menu is a safe diagnostic tool, but changing unknown parameters in other sections can cause the network or display to run unstable.
The problem with Bluetooth and third-party devices
Sometimes the headset icon appears not because of a physical connector, but because of a "stuck" connection over Bluetooth.The phone may believe that the sound should go to wireless headphones that are outside the access zone and block the output to the speaker.
Go to Bluetooth settings and hit Forget Device for all previously connected headsets, speakers, and car systems. Then turn off the Bluetooth module completely. If the icon is missing, then the problem was a software conflict of data protocols.
It is also worth checking if you are connected to the phone through USB-OTG Some kind of device. Some of the external ones. DAC-You or the microphones can be perceived by the system as a headset.
In rare cases, a conflict is caused by a newly installed app that has gained access to a microphone or audio. Check the list of recently installed programs and try to remove those that are related to audio recording, voice recorders or bass boost amplifiers.
Hardware repair and replacement of the connector
If none of the software methods worked and cleaning the connector proved useless, it's likely the hardware that's the problem. The sub-board could have failed. In modern smartphones, the headphone jack is often soldered on the bottom board that connects to the mother's plume.
Inside the connector is a contact group, which eventually oxidizes from moisture or breaks physically, and if the contacts inside are constantly closed, the phone will think that the headphones are connected 24/7, and then only changing the bottom plume will help.
- π¨ Diagnosis - visual inspection of the board for the presence of oxides.
- π Replacement of the plume β the cost of the part is usually not high.
- π§΅ Sweatering - in some models, the connector can be soldered separately.
The cost of repairs at the service center varies by model. For popular like Redmi Note models, parts are available. Self-replacement requires fine electronics skills and tools to open the case.
β οΈ Warning: Opening the case of the smartphone itself deprives you of an official warranty. If the device is warranty, contact an authorized center Mi Store.
