How to turn off the headphone icon in the Xiaomi Redmi phone

The situation where the headphone icon is displayed on the screen of a Xiaomi or Redmi smartphone, even though the headset itself is not connected, is a common and annoying problem. This indicator blocks the output of sound through the main speaker, forcing the user to look for ways to turn off the headphone icon in the phone. Often the system mistakenly believes that the 3.5 mm jack or Bluetooth channel has external acoustics active.

The causes of this failure can range from the banal ingress of moisture or dust into the audio jack to software errors in the shell of MIUI or HyperOS. In some cases, the phone “thinks” that the headset is connected, due to oxidation of contacts or downed settings of sound drivers. In this article, we will discuss all effective methods for fixing this problem.

Program reasons for the appearance of the headset icon

Before disassembling the device, you need to rule out software failures. The MIUI-based Android operating system sometimes mishandles interruptions from audio drivers. This can occur after updating the firmware, installing third-party audio management applications, or after improperly extracting the wired headset. The audio service system cache can overflow or damage, which leads to a false activation of the connection sensor.

It's also worth considering the impact of third-party applications, because some audio enhancers or equalizers can take control of the audio output and not return it to the system after closing, and if you've recently installed these tools, they may be the problem.

It's important to understand that software failure is the most innocuous cause, and unlike physical damage, it's solved by rebooting or resetting the settings without having to climb inside the device's housing.

Basic methods of elimination through reboot

The first and often most effective way to turn off the headphone icon in a Xiaomi phone is to completely reboot the system, which clears RAM and forcibly restarts all system processes, including audio drivers. In most cases (about 60%), a simple reboot eliminates the false definition of the headset.

However, a normal reboot may not help if the process is stuck at the core level, in which case it is recommended to perform a soft reset, for this purpose on Redmi and Poco smartphones you need to press the power button and hold it for 10-15 seconds until the screen goes out and the manufacturer's logo appears.

If the indicator is gone after switching on, but the sound is still quiet or gone completely, the system may have switched to another output channel, in which case you can try to turn up the volume with the buttons on the case, and if the icon is still there, then we can move on to more advanced diagnostic methods.

Cleaning the data of the application "Sound settings"

When a simple reboot doesn't work, you need to manually clean up the system component that handles the audio, and in the MIUI shell, it's often the system application or service that you find in the installed program list, and it's a secure procedure that doesn't delete your personal files, photos or contacts.

To do this, go to the Settings menu, then select the Apps section and then All Apps. In the upper right corner, click three dots and select the Show System Processes option. In the list that appears, find an item associated with sound (for example, Sound Recorder, Audio or MIUI Sound).

Inside the app menu, click Clear and select Clear Everything (or Clear Data) to return the audio settings to factory values, and the phone can then automatically restart or require manual restart to apply the changes.

💡

Cleaning the data of system sound applications resets the driver configuration, eliminating software conflicts that cause a false headset definition.

Sometimes, you should also find Bluetooth and Bluetooth MIDI Service on the list of applications, and for them to also perform data cleanup, which will help if the problem lies in the wireless module, which erroneously believes that the Bluetooth headset is connected.

Diagnostics of physical damage to the connector

If the software methods failed, there is a high probability of physical problems. The 3.5 mm (mini-jack) connector in Xiaomi smartphones is designed so that inside it there are contacts that open when the plug is inserted. If these contacts are oxidized, stuck with moisture or clogged with dust, the phone will constantly “see” the connected device.

Carefully inspect the jack hole in good light, preferably with a magnifying glass, and there should be no villi, dust or corrosion (green or white) inside, even a microscopic dust clump can close the contacts.

• 🧹 Carefully clean the connector with a dry toothbrush or wooden toothpick (metal items to use dangerously!).
• 💨 Blow the connector with compressed air from a can of cleaning equipment.
• 💧 If there is a suspicion of oxidation, you can use a special liquid for cleaning contacts (Contact Cleaner), but only in minimal amounts.

A common cause is moisture. If the phone has recently been in the bathtub or in the rain, moisture may have gotten inside the connector. In this case, you can not use a hair dryer (hot air can damage the adhesive seals and drive moisture deeper).

Use of engineering menu and reset settings

For advanced users, it is possible to check the status of the audio module through the engineering menu, but be careful: changing unknown parameters can lead to unstable phone operation. CIT Test) or ##4636##.

In the test menu, select an item associated with audio (often called Audio or Speaker), where you can run a speaker and microphone test. If the test shows an error or the headphone icon is on even in test mode, the problem is almost certainly hardware.

If nothing works, the last software measure is a complete reset to factory settings (Wipe Data).Be sure to back up all important data to the cloud or computer before doing so. Go to Settings → About Phone → Settings Reset → Erase all data.

⚠️ Warning: Full reset will delete all photos, contacts and apps, and use this method only if you are sure that the problem is not the hardware, or as a last chance before going to the service.

Hardware repair and replacement of the plume

When software methods and cleaning the connector do not help, it is a malfunction of the bottom plume (sub-board) or the main module. In Xiaomi Redmi smartphones, the headphone jack is often soldered on a separate board that connects to the motherboard with a flexible plume, which could move away or rub.

In some models (such as the Redmi Note series), the 3.5mm connector is combined with a charging connector on a single board, replacing this board is a standard and inexpensive procedure in service centers, and if the connector is on the motherboard, repair requires qualification and soldering.

💡

When buying a spare part for self-repair, pay attention to the board version - for the same phone model (for example, Redmi Note 9), there may be different revisions of the lower boards.

Self-replacement is possible if you have the skills to disassemble the equipment and the necessary tools (driver kit, sucker, mediator). However, if the phone is warranty, any opening of the case will lead to the loss of warranty obligations.

⚠️ Warning: Do not try to pick inside the connector with a metal needle or pin. You can close contacts on the board, which will cause the audio chip or the entire motherboard to burn.

If you're not sure about your abilities, you should go to an authorized service center, and the diagnostics are often free, and the wizard will tell you exactly whether you need to change the plume or the problem deeper.

Interim solutions and workarounds

If the headphone icon is on and you can't fix the phone right now, you can try to get around the software restriction. There are apps that force the audio output to the speaker, ignoring the system status of the headset. One of these popular solutions is Lesser AudioSwitch.

This app requires superuser (Root) rights to work properly, but some features may be available without them, depending on the Android version. Once installed, select Speaker as the output device. This can cause the phone to ignore the signal from the mini-jack connector.

Another option is to use a Bluetooth adapter or a 3.5mm USB-C adapter (if the phone supports OTG), and connecting an external sound card can shift the priority of the output, although the headphone icon may remain in the status bar.
